If the N-P-K rating is 10-6-4, for example, and the weight of the bag of fertilizer is 25 pounds, the fertilizer bag contains 2.5 pounds of nitrogen. To find the nitrogen content of a fertilizer, multiply the number in the N position of the N-P-K rating by the total weight of the fertilizer. Subsequently, question is, how much does a gallon of 10 34/0 fertilizer weight? Liquid: Liquid:Ĭorrespondingly, what is the density of urea fertilizer?īulk densities, angle of repose of some materialsįunction. It takes into account the space/air between the granules, and is typically about 50 – 60% of the Specific Gravity, when expressed on a volumetric basis. kg per cubic metre (m3) or kilolitre (kL). Swap will redirect you to Percent to PPM calculator. The Bulk Density is the weight of the product in a given volume, e.g. Reset tab will reset all the values and we can carry out further calculation. However, bulk density measurements can be reported in a variety of ways so it is important to have awareness of their definitions and which one to use when spreading fertilizer. SummaryThese examples provide you with some guidelines to follow in order to calculate nutrient costs on a per pound basis.Bulk density is measured by weighing a container of known volume filled with a fertilizer sample. When soil test results for nitrate-nitrogen are not available, a value of 3 ppm is used to calculate the nitrogen recommendation. Second, calculate the lbs per gallon of 9-18-9 for the nitrogen, phosphorus, and potassium nutrient components of this fertilizer product. For every ppm of average nitrate-nitrogen concentration to a 4-foot depth, the recommended nitrogen need is reduced by eight pounds per acre. Sharpen your pencils and follow along with these examples of nutrient cost calculations.Įxample 1: Single Nutrient ProductsFor single nutrient fertilizer products such as anhydrous ammonia (82-0-0) or 28% UAN (28-0-0), calculating the costs per pound of nutrient is simple. Published at the Chat 'n Chew Cafe, 26 March 2002URL: Reckoning for the Mathematically ChallengedRelative nutrient costs play an important role in the fertilizer selection process. Fertilizer Reckoning for the Mathematically Challenged (Purdue Univ.) * Total gallons of fertilizer (H) * Gallons of fertilizer applied per acre (I) = H / D * Pounds of Nitrogen applied per acre (J) = I x E Using the example above, how many pounds of Nitrogen were applied per acre? * 300 gallons of fertilizer applied to 20 acres = 15 gallons of fertilizer applied per acre * 1.069 lbs. In the example above, 280.6 gallons of fertilizer were required to hit the desired target of 15 lbs. N (Nitrogen) per acre * 20 acre field _Fertilizer, liquid:_ * 10-10-10 formulation * Product weighs 10.69 lbs. In 1988, 92 of the total dry fertilizer was sold as bulk material, with only 8 in bags. Dry fertilizers (solids) still constitute the major part of the fertilizers sold in Michigan. Anhydrous ammonia and N solutions accounted for 78 of the total liquids sold. Liquid Fertilizer Application Calculations TemplateAgricultureCalculate how much liquid fertilizer you need to apply to deliver some number of pounds of Nitrogen to a field. In 1988, liquid fertilizers accounted for 28 of the market.
