Crop yield, fertilizer, seed rate & irrigation
Estimate total production from a yield rate and area.
Seeding rate (kg/ha) from population, seed weight, germination & purity.
Fertilizer amount needed to hit a nutrient target rate.
Actual kg of N, P and K in a fertilizer bag.
Simplified lime estimate to raise soil pH to target.
Plants per hectare/acre from row and plant spacing.
Spacing needed to hit a target plant population.
Germination % from seeds germinated vs planted.
Yield rate derived from an actual harvest and area.
Net irrigation (mm) from ET0, crop coefficient & rainfall.
Reference ET0 via the Hargreaves-Samani equation.
Flow rate from volume/time or pipe diameter & velocity.
Total water and application rate for a drip system.
