Liquid Fertilizer Calculator
Concentrate needed from water volume and dilution ratio
Dilution
Fertilizer concentrate
0 mL
e.g. 500x = 2 mL per 1 L water. Foliar feeds are usually weaker (500-1000x).
By dilution ratio
⚠️ 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 is fertilizer dilution calculated?
Concentrate (mL) = water (L) × 1000 ÷ ratio. For 20 L at 500x, you need 40 mL of concentrate.
Do foliar and drench differ?
Foliar sprays are usually weaker (about 500-1000x), while soil drenches are relatively stronger. Adjust to crop and growth stage.
What if I over-apply?
Too concentrated can cause salt stress or leaf burn. Start weak and increase gradually while watching the plant response.
