Optimise soil health and plant nutrition. Calculate lime requirements, fertiliser blends, pH adjustment, compost rates and soil carbon sequestration.
Calculate exact N-P-K blends using Urea, DAP, MAP, MOP and other fertilizers. Hit your nutrient targets precisely.
Calculate →Calculate lime required to raise soil pH based on buffer pH and target pH. Essential before planting.
Calculate →Calculate pH adjustment requirements. Interpret soil test results and plan amendments.
Calculate →Identify and correct nutrient deficiencies from soil test results and crop symptoms.
Calculate →Calculate compost application rates based on nutrient content and soil requirements.
Calculate →Calculate manure application rates for nutrient budgeting. Reduce commercial fertiliser costs.
Calculate →Calculate soil organic carbon stocks and sequestration potential for carbon farming.
Calculate →Assess soil compaction risk based on soil type, moisture and machinery weight.
Calculate →Every $1 spent on correcting soil pH returns $3-5 in yield. Optimal N-P-K fertiliser saves 20-30% on input costs. Use these calculators to turn soil test results into precise action plans — no more guesswork, no more wasted fertiliser.
