Soil pH & Amendment Calculator — Fix Acidic or Alkaline Soil for Indian Gardens

🌿 Soil pH & Amendment Calculator

Find out if your soil is too acidic or too alkaline for your plants, and calculate the exact amount of lime (to raise pH) or sulphur (to lower pH) needed to correct it. Covers pots, grow bags, raised beds, and open garden beds.

ℹ️ What is Soil pH? pH measures soil acidity or alkalinity on a scale of 0–14. pH 7 is neutral. Below 7 is acidic; above 7 is alkaline. Most vegetables and herbs prefer pH 6.0–7.0. Getting pH right is the single most important factor for nutrient availability and plant health.

⚠️ Disclaimer: pH amendment calculations are estimates based on standard soil science principles. Actual requirements vary significantly by soil composition, organic matter content, buffering capacity, and local conditions. Always get a professional soil test from your nearest Krishi Vigyan Kendra (KVK) or agricultural university before applying large quantities of lime or sulphur. Apply amendments gradually and retest after 4–6 weeks. Over-application of lime or sulphur can cause serious soil damage.
