0 kg
Enter the soil-test or label rate per 10a. Typically 100-300kg/10a for pH correction.
Details
⚠️ This calculator is a simple reference tool based on general agricultural guidelines, recommended dilution ratios, mixing proportions and publicly available references. In real field conditions the appropriate dilution, dose and spray volume can vary with crop type and variety, growth stage, weather, soil, water quality, growing method and the quality/concentration of the materials used, so results may differ from actual needs. Pesticides, fertilizers, liquid fertilizers, microbial inputs, JADAM Sulfur, JADAM Wetting Agent and other natural/chemical materials can cause phytotoxicity, stunting, crop loss, disease or yield reduction through overuse, improper dilution or mixing with incompatible substances. Always check the product label, manufacturer guidance and relevant authorities, and test on a small area before full use. calcstool.com assumes no legal liability for any direct or indirect damage arising from manufacturing, diluting, mixing, fertilizing, spraying or other agricultural activity based on these results.
FAQ
How much lime do I need?
Total = area (10a) × rate per 10a. e.g. 1000 pyeong (~3.3×10a) at 200kg/10a ≈ 661kg, or 34 bags of 20kg.
How do I set the rate?
A soil test recommendation is most accurate; 100-300kg/10a is common for pH correction.
Do lime types differ?
Yes — hydrated lime, dolomite, oyster-shell lime differ in neutralizing value and rate. Check the product.
