See the following table for N and P recommendations for grain sorghum … Manure applications, if available, are a good source for many nutrients, including zinc. • N, P, Zn, (and K) have reliable soil tests to measure nutrient availability and predict fertilizer needs. The nutrient recommendation for a soil testing in the optimum range for P and K is 120 pounds of N, 65 pounds of P 2 O 5, and 120 pounds of K 2 O for a crop with a 21-ton per acre yield potential. Since growers do not want to overapply nitrogen, they can manage nitrogen with a multiple-application plan. Millet is important in some farm enterprises in Minnesota. The University of Nebraska–Lincoln recommendation for the economically optimal N rate (EONR) for grain sorghum is estimated using the equation: EONR (lb/acre) = [70 + (1.1 x EY) – (20 x OM) – (14 x NO. As a result, many growers assume they can save on other input costs as well. Optimum nutrient availability occurs within a pH range of 6.5 to 7.5. Where nitrogen comes from does not … Properly fertilized sorghum used an average of one inch more water than unfertilized sorghum but produced 12.5 hundred weight (22 bushels) more grain per acre. recommendation for an expected yield of 210 bu/A, multiply the 150 bu/A recommendation in the table by 1.4 (210÷150=1.4). This critical component enables the soil to provide nutrients to plants. This critical component determines if nutrients in the soil can be taken up by the plant. sorghum. Both phosphorus and potassium are immobile nutrients in the soil and are generally safe from leaching. Soil tests for some of these nutrients are difficult to interpret. Sorghum is no exception, requiring 1.12 pounds per bushel of grain produced, which is very similar to the recommendation for corn. (C02) Corn (for Grain) Irrigated 250 bu/a31. Zinc recommendations for corn and sorghum production _____11 Lime recommendations based on SMP or Sikora buffer pH methods, given in pounds/acre of finely ground pure calcium carbonate (CaCO 3) to increase soil pH from its present -N), soil organic matter, and grain price relative to the price of fertilizer nitrogen. The effect of starter fertilizer is most often observed on grain sorghum in areas where nights are cooler. A soil pH range of 6.0 to 7.5 is ideal for sorghum production, with pH of 6.5 considered optimum. Nitrogen is particularly needed on most soils and exerts the greatest effect on yields. (001) Corn (for Grain) Dryland4. ™ ® Trademarks of Corteva Agriscience and its affiliated companies. Sorghum planted under cool soil conditions can show a significant early growth response when starter fertilizer is properly applied. Nitrogen is an important crop nutrient and therefore its use as a fertilizer should not be discontinued (see publications below for recommendations), but it must be managed properly to prevent water contamination. For example, if nine gallons per acre of 7-21-7 fertilizer, weighing 11.0 pounds per gallon is used, then 99 pounds of material is applied per acre. Adjusting high pH downward is usually impractical. Earlier maturity may also result in slightly drier grain at harvest (one or two percentage points lower grain moisture). In addition, common phosphorus fertilizer sources contain nitrogen and sometimes sulfur, which tend to lower the pH within the narrow band to allow greaterphosphorusavailability.Growers should base the amount of phosphorus fertilizer applied on soil test estimates and yield goal. Research at the University of Nebraska and other Midwestern universities has shown that significant yield increases … Ideally, producers should base fertilizer recommendations on soil test data. Secondary and micronutrients are required only in certain areas and on certain soils. Assistant Professor & SDSU Extension Soil Fertility Specialist. Kansas State cautions that the use of phosphate for aluminum toxicity reduction is a temporary solution, since it does not change the pH of the soil. Sustainable sorghum farming strategies – growing tips and fertiliser recommendations to improve sorghum crop quality and yield. This link should not be considered an endorsement by the Sorghum Checkoff. © 2021 Corteva. Under irrigated conditions, irrigation water can supply much of a crop's sulfur needs if irrigation water contains sulfates. 1.2 lbs. Extension management recommendations to produce a high yielding, economical grain sorghum crop. The benefits of rapid early growth include more uniform stand establishment and plant size. Starter fertilizer applications for sorghum is a sound practice in the Texas High Plains. 3. Nitrogen is the nutrient most often limiting in sorghum production. Tag: Grain Sorghum Fertilizer Requirements. Figure 2: High pH induced iron deficiency chlorosis. Sulfur incorporated in a starter mix is a good method of application. Fertilizer has a significant influence on water use, as illustrated in Table 2. (702) Canola Winter Type3. Potassium is sometimes promoted as a stalk strength or standability-enhancing nutrient. Sidedress nitrogen should be applied by the time sorghum reaches the five-leaf stage. For the low P and low K category, the new recommendation is 210-140-170. When pH falls outside the optimum range, agronomists often recommend applying phosphorus in or close to the seed furrow or in a narrow band a few inches to the side and a couple of inches deep into the soil. Once sorghum is established, two critical growth stages occur when lack of nitrogen can significantly impact yield. The rate of starter fertilizer depends on the salt content, or index, of the fertilizer, the distance between the fertilizer and the seed, and the soil texture. Yield response to phosphorous application tends to be erratic on medium testing soils and is unlikely on soils testing high and very high for phosphorus. Sign-up for our newsletter. Economic information is collected on each CGSRVP The phosphorus content of the fertilizer is not considered when the salt index is calculated. Materials and Methods Field experiments were conducted on a Hoosic soil (pH 6.4, medium soil tests for P and K) at the Valatie Research Farm in Columbia County, NY. Lubbock, TX 79403 • Fe and zinc are the micronutrient most likely to be deficient in Kansas for sorghum. One of the things common to all three growers is having adequate nutrients. Mr. Reddy-May 6, 2017 Want to stay up-to-date on all things sorghum? Jason Clark . The yield goal needs to be realistic, taking into account moisture, soil type and cropping sequence. nitrogen/acre from previous manure application.Actual rate = 110 x 1.2 - 40 -15 = 77 pounds actual nitrogen needed. ECC (effective calcium carbonate) at a significantly lower cost. (C03) Corn (for Grain) Irrigated 300 bu/a Click cancel to return to SorghumCheckoff.com. It is best to have fertilizer . of yield goal Sorghum seed is sensitive to fertilizer burn-do not allow fertilizer to come in contact with seed. Recommendations for fertilizing corn should be used for the sorghum family, including the 100-125 kg/ha (90-110 lb/ac) nitrogen applied at planting. Nitrate is a colorless, odorless, and tasteless compound and it is also one of the most Compaction, excessive soil moisture and low soil temperatures contribute to iron chlorosis severity. Phosphorus Phosphorus is especially limited when pH drops below 6 or is above 8. Balanced fertility programs improve water use efficiency (drought tolerance) and grain yield, at the lowest possible cost. Fertilizing Grass Pastures and Hayland , NebGuide G1977 Fertilizing Proso Millet , … The concentration of aluminum in the soil increases as soil pH decreases, eventually becoming toxic to crop growth. Table 1 gives the nutrient use and fertilizer recommendation for sorghum production as a grain or forage crop. Optimum Fertility Improves Water Use Efficiency. Nitrogen can be applied at varying times with good results. (002) Corn (for Grain) Irrigated 150 bu/a29. (C01) Corn (for Grain) Irrigated 200 bu/a30. Failing that, research at Kansas State University shows that sorghum requires 1.6 pounds of nitrogen per bushel of expected yield, assuming 2.0% organic matter. Zinc is a nutrient that is often overlooked, but is a crucial element for optimum sorghum production. When pH drops below 5.6, liming is warranted to reduce soil acidity,which then allows plants to utilize soil nutrients. The most dramatic visual response to starter fertilizer occurs when soils are cool at planting time. In productive irrigated situations, up to 200 pounds of nitrogen will be required. Sorghum response to phosphorus is most likely on soils testing medium or lower. Fertilizer Recommendations by Crops, Categorized (Crop codes in parentheses) I Field Crops 1. • Plant part: Leaves are higher then stems, upper leaves are higher than lower leaves • Tillers: Higher than main plants • Maturity: Higher yields result in lower HCN • Fertilizer: Do not over apply N and amend P and K deficiencies • Frost: Frost concentrates HCN, delay harvest or grazing few days for HCN to … The soil will become more acidic each year and liming will eventually be necessary. Use of pop-up fertilizer placed in direct contact with the sorghum seed is more risky, but can be done successfully by precisely metering a lower rate. fertilizer dollars in sorghum is from N and P. • Sulfur becoming an issue on some soils. Table 1 shows the typical nutrient removal for a 100-bushel per acre sorghum crop. Sorghum Production Information Guide.  | Tags: agronomy library, sorghum management, sorghum, grain sorghum, fertilizing, By Brent Bean, Ph.D., Sorghum Checkoff Agronomist. BMR sorghum Fertilizer requirements for sweet sorghum depend on the fertility levels of the field in which it is grown. Planning a soil fertility strategy for grain sorghum has many of the same requirements as corn. EC 750 Original Authors: 2005 – Jim Gerwing . Posted on Mar 11, 2019 Of these nutrients, the key elements include nitrogen, phosphorous, potassium, zinc, and sulfur. A multiple-applicationplan is particularly important on sandy soils where preplant nitrogen can leach out of the sorghum root zone following heavy rains. The Sorghum Checkoff is not responsible for the quality, accuracy or nature of the third-party link. The likelihood for deficiency will be greater on sandy soils when compared to fine textured soils. Even if soil tests like phosphorus (P) are in the “medium” range, one of the purposes of “starter” fertilizer for nitrogen (N) and P is to “kick-start” or stimulate growth right after emergence. Soybean is an important crop in Minnesota and provides a significant return for many farms. The first stage occurs approximately 30 days after emergence, when sorghum enters a rapid growth period and the potential number of grain kernels start to form. Adequate potassium levels are necessary for strong stalks, but high potassium rates alone will not provide total protection from stalk lodging. Thus, a good starter fertilizer might range from a ratio of 1-4-0, 1-3-1, 1-3-3, to 1-1-1, depending on the rate of fertilizer required. Example: Yield goal pounds per acre = 6200 lb/ac, carryover nitrogen is 40 lb/ac from soil test. Prior to his current role, he was a Field Sales Agronomist involved in sorghum production with growers in Nebraska. Low and very low phosphorus levels, as indicated from soil tests, will likely show a response to applied phosphorus (45 to 60 pounds broadcast or 20 to35 pounds in a band) unless yield potential is restricted by insufficient moisture. Soil test results will allow you to develop and fine-tune a sound fertility management plan. Estimated nutrient requirements for grain sorghum based on stage of growth are presented in Table 4. Soil tests are a good tool for predicting zinc needs. The fertilizer needs of the crop are often neglected while attention is mostly directed at fertilizing other crops in the rotation. Check out the sorghum soil management page for current University of Nebraska-Lincoln Extension recommendations for nitrogen, phosphorus, potassium, zinc, iron, and sulfur. Grain sorghum requires approximately 1.2 pounds of nitrogen for every bushel produced. For production on sandy soils with low organic matter, it is suggested to try a 10 to 15 pounds per acre sulfur application to ascertain the likelihood of a sulfur response. The cost of planting grain sorghum is much less expensive than other crops, primarily because of seed price. nitrogen/acre from previous manure application.Actual rate = 6200 x .021 - 40 -15 = 75 pounds actual nitrogen needed. Potassium In most U.S. soils,potassium is available in adequate supply for the needs of sorghum. He has been with Pioneer Hi-Bred since 1990. Fertilizer management for high yielding grain sorghum Nitrogen is the main building block of plants and is used to make amino acids, proteins and then biomass. Soil pH. Nitrate (NO3) is a naturally occurring form of nitrogen found in most soils. He currently serves as a Technical Product Manager and is involved in sorghum production with growers in Kansas, Oklahoma, and Texas. Applications should be timed such that nitrogen is in place and available for this rapid growth phase, as yield potential is being established at this time. Bill McClure holds a Bachelor of Science degree in agronomy from the University of Nebraska. Early growth response does not always increase grain yield but may result in earlier maturity of the crop. Recommendations for nitrogen, phosphate, and potash are summarized in the tables that follow. Soil pH. By concentrating the phosphorus,the nutrient has less opportunity to become “tied up”by the soil. If your lab reported in percent, multiply percent N by 10,000 to get ppm. Zinc is most likely deficient in areas where topsoil has been removed and under high yield conditions. Toll Free: (877) 643-USCP. Phosphorus and K fertilizer rates of 0, 0.5, 1.0, and 2.0 times the recommended rates (recommended rates were 79 kg/ha P2O5 and 101 kg/ha K2O) for the lowest soil test values were applied broadcast and incorporated before planting. Fertilizer Recommendations Instructions (PDF) Fertilizer Recommendation Program (XLS) Soil Test Interpretations and Fertilizer Recommendations (PDF) Horticultural Crops. Soils testing in a medium or higher range for potassium (K) generally do not show a yield response to added potassium fertilizer. Soil pH This critical component determines if nutrients in the soil can be taken up by the plant. A 5 to 7 ton forage sorghum crop will remove about 40 lb/acre P 2 O 5 and 180 lb/acre K 2 O. Kansas State University research suggests that on acid soils, banding 35 pounds per acre P2O5 at planting can increase yield to the same level as liming at a rate of 5000-10,000 pounds. Soil Testing Program Manager. ©2016 United Sorghum Checkoff Program. On a per bushel basis, grain sorghum requires a similar amount of most nutrients as corn. Information from the CGSRVP fields is used to improve and refine recommendations to meet the needs of Arkansas grain sorghum farmers and identify areas which need additional research. Other credits include 15 lb. Extension Soil Specialist. After each cut, 50 kg/ha (45 lb/ac) more nitrogen should be applied to encourage growth. Optimum nutrient … Under low rainfall conditions with low yield potential, 30 to 60 pounds of nitrogen per acre may be adequate. Figure 1: Phosphorus deficiency shown by purpling is often aggravated by other conditions, such as cool wet soils and slow root growth. Rely on experience and local recommendations to determine the need to supplement these nutrients where a grain sorghum crop is planned. Nitrogen In most farming environments,the most limiting nutrient to yield is nitrogen. Nutrient use efficiency deteriorates outside this pH range and liming to raise pH to 6.0 or above is effective. 4201 N. Interstate 27 University research on boron, copper and manganese does not show a consistent response for most soils. This method may be applicable on leased land situations or for fields where crop production future may be limited. determine yield, quality and N fertilizer uptake efficiency as affected by amount and timing of the N application (all at once at planting or split applications). Although many producers view grain sorghum as a low maintenance crop, with its deep fibrous root system, sorghum responds well to nutrient applications, especially in lower testing soils. Do not place urea or ammonium thiosulfate in direct contact with the seed. A complex plant disorder associated with high pH soils and soils containing soluble salts that reduce the availability of iron. The salt index of a fertilizer can be determined by adding the rate of nitrogen (N), the rate of potassium (K20), and one half the rate of sulfur (S) applied. placement separate from seed, but a maximum of 10 pounds N/acre may be placed with the seed. A water analysis is helpful to determine sulfur content of the water. Phone: (806) 687-8727 Soil tests should be taken to determine what kind and amounts of fertilizer should be used. For a grain yield of 7,500 pounds per acre, sorghum needs approximately 25 inches of water during the growing season. Table 2. Zinc Soil test zinc above 1.0 ppm does not require any fertilizer zinc additions to … These salt limits are designed to provide safe conditions for all environments, with rare exceptions. Fertilizer nutrient needs for grain sorghum are based on expected yield, nutrient levels in the soil and fertilizer-nitrogen costs. At boot stage, 65 to 70 percent of the total nitrogen has been taken up. Sorghum-sudan grasses can grow in a wide pH range with 5.5-7.5 as the optimum. In all situations, a nitrogen credit should be given for residual nitrogen in the soil (from soil test), nitrogen content in irrigation water, and nitrogen contribution from a previous legume crop or applied manure. Soybean crop yields will decrease when it lacks essential nutrients. Growers must base the amount of nitrogen applied on factors including yield goal, the amount of residual nitrogen in the soil profile and the expected nitrogen amount mineralized from soil organic matter. Multiply ppm ammonium nitrogen (from your lab report) by 2.7 to get pounds of ammonia N in an acre foot of pond water. Equations for determining N, P and K nutrient recommendations for sorghum can be found in (Table 1). Use of starter and sidedress applications should be considered when the potential for nitrate leaching is high. Sorghum utilizes nitrogen rapidly after the plants reach the five-leaf stage. Table 1. Follow soil test recommendations to determine nutrient requirements. Some states now suggest taking a soil sample to a shallower depth for no-till. (701) Canola Spring Type2. The nitrogen fertilizer recommendation in South Texas is 2 pounds of nitrogen for each 100 pounds per acre of grain yield. See NebGuide G361, Using Starter Fertilizers for Corn, Grain Sorghum and Soybeans. Improving the Profitability, Sustainability and Efficiency of Nutrients Through Site Specific Fertilizer Recommendations in West Africa Agro-Ecosystems pp 241-252 | Cite as Improving Agronomic Efficiency of Mineral Fertilizers through Microdose on Sorghum in the Sub-arid Zone of Burkina Faso The actual nitrogen rate is based on the expected yield goal for the specific field, multiplied by a factor of 1.2 units per bushel (or 2.1units per hundred weight or .021 units per pound) minus any nitrogen credits. Phosphate combines with the toxic aluminum, effectively reducing aluminum concentrations in the soil. Additional Resources. Nutrient use efficiency deteriorates outside this pH range and liming to raise pH to 6.0 or above is effective. Adequate nitrogen must be present to support this rapid growth period. Approximate quantity of nutrients in a 100 bushels per acre sorghum crop, Source: Adopted from National Plant Food Institute. Row applied starter fertilizer can maximize uptake efficiency for nutrients such as phosphate, zinc and sulfur in low testing soils. Soil testing is the basis for determining which of these nutrients will likely limit production. Zinc is usually applied along with phosphorous and potassium. Soil sampling and analysis are critical for this determination and will prevent both the overapplication and underapplication of fertilizer. In general, the application of excessive amounts of N, K20 and S too close to the seed will delay grain sorghum emergence and reduce stand. A soil pH range of 6.0 to 7.5 is ideal for sorghum production, with pH of 6.5 considered optimum. SDSU Extension fertilizer recommendations are based on field research in South Dakota and neighboring states . In some soils, growers also may need to adjust pH to ensure the availability of soil nutrients to the sorghum. The second stage is at or just prior to the boot stage, which occurs approximately one week prior to heading, when nitrogen supports good pollination, grain set and grain fill. The fertilizer used as a starter should contain a small amount of nitrogen; most, if not all, of the recommended phosphorus; and possibly some potassium. Growers should consider applying no more than 50 percent of the anticipated needed nitrogen as a preplant application and then adjusting the remainder of the nitrogen applied to meet the anticipated yield potential as the season progresses. Going into the growing season, growers often find it difficult to set a yield goal and, in turn,struggle with calculating the proper amount of nitrogen needed. For information about horticultural recommendations please email Ward Upham. Sulfur An often neglected nutrient in grain sorghum is sulfur, which improves nitrogen use efficiency and is especially important as yield increases. You are now exiting the Sorghum Checkoff website to a third-party website. As shown in the graph below, yield becomes less responsive to nitrogen as yield approaches 150 bushels per acre becauseyield becomes limited by other factors. Soybean fertilizer recommendations Previous Next. At 100 pounds per acre, a total of seven pounds of nitrogen (.07 x 100) and seven pounds of potassium (0.7 x 100) would be applied per acre. Example: Yield goal bushel per acre = 110 bu/acre, carryover nitrogen is 40 lb/acre from soil test. Follow soil test recommendations to determine nutrient needs and fertilizer recommendations. … Liming. If a grower wants to produce a 100-bushel sorghum crop, the grower must support this yield goal with a supply of adequate nutrients, including phosphorus, nitrogen, sulfur and potassium. Earlier flowering can improve yield in years of early frost. Ron Gelderman . The appropriate use of nitrogen and phosphorous fertilizer for sorghum production could make an important contribution to optimize profit through increasing production and productivity of sorghum in areas, where there is low practice of using improved technologies such as optimum level of fertilizer [10]. Fertilizer is an important production input for optimum yields. Proper fertilization for adequate levels of all nutrients is the best way to maximize standability. Salt index limits are listed in Table 3. MANURE—It is important to consider nutrient credits from manure applied previously or to the current crop and adjust fertilizer rates accordingly. Fertilizer or manure ammonia is converted to nitrate only after it is applied to the field. Adjusting high pH downward is usually impractical. Other credits include 15 lb. A general rule to thumb for nutrient removal of NPKS is 24:8:32:5 3. A forage sorghum silage crop removes large amounts of nutrients, so soil testing is essential with this crop. Sulfur can be lacking on sandy soils low in organic matter. Growers should strive to keep the nitrogen to sulfur ratio at approximately 15-to-1. However, growers may need to add potassium in very shallow soils with reducedrooting depths and on sandy soils. All Rights Reserved. Fertilizer recommendation (Yield goal – soil test value) 1. The estimated salt index would be 14 pounds per acre. Application methods include preplant broadcast or banded as a starter at planting time. N/bu. Fertilizer Recommendation Guide. 2. If the phosphorus level in the field is low, starter fertilizer is an excellent way to get the phosphorus … The best example of this involves the use of fertilizer.
