Fertilizer Application Rate Per Acre
Fertilizer application rates per acre are the quantity of fertilizer that is used to a system location of land to offer the needed nutrients for crop development. Fertilizer application rates depend upon numerous aspects, such as the kind of crop, the soil fertility, the nutrition material of the fertilizer, and the ecological conditions. Fertilizer application rates are normally revealed in kgs or pounds of nutrients per hectare or acre.
Factors Influencing Fertilizer Application Rates
Crop type: Different crops have various nutrient requirement and uptake patterns. Cereals require more nitrogen than vegetables, and fruit crops require more potassium than leafy veggies. The crop type likewise identifies the timing and approach of fertilizer application.
Soil fertility: The soil fertility is the capability of the soil to provide nutrients to plants. Soil fertility depends upon the soil texture, structure, raw material, nutrient, ph, and salinity status. Soil screening is a helpful tool to evaluate soil fertility and figure out the fertilizer requirements of the crops.
Nutrient material of the fertilizer: The nutrition material of the fertilizer is the portion of nitrogen (N), phosphorus (P2O5), potassium (K2O), and other micronutrients in the fertilizer. The nutrition material identifies just how much fertilizer is required to provide a specific quantity of nutrients to the crops. Urea has 46% N, while ammonium nitrate has 34% N. Therefore, more ammonium nitrate is required to offer the very same quantity of N as urea.
Environmental conditions: The ecological conditions impact the accessibility and loss of nutrients in the soil. Aspects such as temperature level, rains, watering, drain, disintegration, seeping, fixation, volatilization, and denitrification affect nutrition biking and retention in the soil. High temperature levels and rains increase the loss of nitrogen through volatilization and leaching, while low pH and anaerobic conditions increase the fixation of phosphorus.
Calculating Optimal Fertilizer Application Rates (FAR) Per Acre
- The suggested nutrient rate (RNR) for the crop: This is the quantity of nutrients that are needed by the crop to accomplish a specific yield level. The RNR can be acquired from extension services, research study institutes, or literature sources.
- The readily available nutrient supply (ANS) from the soil: This is the quantity of nutrients that are currently present in the soil or can be provided by natural sources such as manure or garden compost. The ANS can be approximated from soil screening or previous cropping history.
- The nutrition usage performance of the crop: This is the ratio of nutrient uptake by the crop to nutrient used by fertilizer. The NUE depends upon the crop type, development phase, fertilizer type, positioning, timing, and ecological conditions. The NUE can be presumed from typical worths or determined from field trials.

FAR = (RNR– ANS)/ NUE
For example, expect a farmer wishes to grow wheat on one acre of land in India. The RNR for wheat is 120 kg N/ha, 60 kg P2O5/ha, and 40 kg K2O/ha. The ANS from soil screening is 20 kg N/ha, 10 kg P2O5/ha, and 15 kg K2O/ha. The NUE for wheat is 0.5 for N, 0.3 for P2O5, and 0.4 for K2O.
FAR for Wheat
- FAR (N) = (120– 20)/ 0.5 = 200 kg N/ha
- FAR (P2O5) = (60– 10)/ 0.3 = 167 kg P2O5/ha
- FAR (K2O) = (40– 15)/ 0.4 = 63 kg K2O/ha
Converting FAR from kg/ha to lb/acre
- FAR (N) = 200 x 0.89 = 178 pound N/acre
- FAR (P2O5) = 167 x 0.89 = 149 pound P2O5/acre
- FAR (K2O) = 63 x 0.89 = 56 pound K2O/acre
To transform FAR from nutrient to fertilizer, divide by the nutrition material of the fertilizer. If the farmer utilizes urea (46% N), single extremely phosphate (SSP) (22% P2O5), and muriate of potash (MOP) (62% K2O) as fertilizers, the fertilizer application rate is:
FAR (MOP) = 56/ 0.62 = 90 pound MOP/acre
