Agriculture
Irrigation Water Requirement Calculator
Calculate daily irrigation water requirement in gallons based on crop water demand (Kc Γ reference ET), rainfall, system efficiency, and field area. Use it for irrigation scheduling that meets crop needs without overwatering or wasting energy.

Agriculture
Fertilizer Application Rate Calculator
Calculate the pounds of fertilizer needed to raise soil nutrient levels to a target based on field size, soil-test results, fertilizer concentration, and application efficiency. Use it at planting to avoid both under-application (yield loss) and over-application (cost waste and environmental harm).
