Crops Calculators — Agriculture
Field-level crop planning: compost and fertiliser application rates, cover crop seeding rates, crop water requirement, plant and row spacing, and days to maturity. Application rates are per acre, so confirm your field area first if the tools are to agree with each other.
All Crops Calculators
Calculate tons of compost needed per acre based on target application rate and field size.
Calculate cover crop seeding rates for single species or mixes by weight per acre.
Estimate daily and seasonal water needs for crops based on ET rate and growth stage.
Calculate estimated harvest date from planting date and crop days-to-maturity.
Calculate fertilizer application rate per acre based on soil test results and crop needs.
Calculate grain bin storage capacity and estimate storage time based on moisture content.
Calculate greenhouse heating costs from volume, target temperature, and energy source.
Estimate total harvest yield from planted acreage, expected yield per acre, and crop type.
Calculate the correct pesticide dilution ratio and amount per tank for spray applications.
Calculate row spacing, plant spacing, and total plants per acre for any crop.
Calculate optimal raised bed layout and spacing for maximum garden productivity.
Calculate seed germination percentage and the number of seeds to plant for desired stand count.
