Calculate fertilizer grams per plant for a feed program.
Because only the nitrogen analysis is actual nutrient, the grams of product per plant is the nitrogen dose divided by the analysis. Feeding per plant spreads fertilizer evenly and prevents a few large plants, or the weak ones, from dominating the dose.
Fertilizer per Plant
Per plant = N dose ÷ (N% ÷ 100); total = per plant x plants
Per plant = N dose ÷ (N% ÷ 100); total = per plant x plants Because only the nitrogen analysis is actual nutrient, the grams of product per plant is the nitrogen dose divided by the analysis.
