Soil Health Score
Soil Reaction Diagnosis
Neutral (Ideal for Nutrient Uptake)
Soil pH is in the optimal range (6.5 - 7.5). Major and micro nutrients are readily bioavailable.
ICAR Fertilizer Adjustments
Based on the standard Soil Test Crop Response (STCR) protocol (+25% for low, normal for medium, -25% for high):
Soil Amendment Prescription
No Chemical Amendments Needed
Soil pH is favorable. Continue standard nutrient replenishment.
Organic Carbon Strategy:
CRITICAL: Organic carbon is low (< 0.50%). Soil biology and water retention are depleted. Apply 5–8 tonnes of well-rotted FYM, sow green manure (Dhaincha/Sunhemp) before Kharif, and strictly avoid burning crop residues.

How to Collect Soil Samples for Testing (मृदा नमूना संग्रह विधि)
Follow the 5-step scientific composite sampling procedure to ensure 100% accurate lab recommendations and avoid costly fertilizer miscalculations.
Divide Field into Homogeneous Units
खेत का विभाजन करें
Do not mix different soil types. Divide field based on slope, soil color (black vs red), past fertilizer history, and drainage. Sample each distinct block separately.
Maintain Standard Sampling Depth
उचित गहराई से नमूना लें
Field Crops (Wheat, Paddy, Cotton, Soybean): 0 to 15 cm depth. Horticultural Orchards (Mango, Grapes, Pomegranate): 0 to 30 cm and 30 to 60 cm. Pasture/Grasses: 0 to 5 cm.
Make V-Shaped Cut in Zig-Zag Pattern
V-आकार का गड्ढा बनाकर मिट्टी निकालें
Walk across the field in a zig-zag trajectory. Clear surface litter, dig a V-shaped pit to 15 cm depth, and shave a 1-inch (2.5 cm) thick vertical slice of soil from the face. Collect from 12–15 spots per acre.
The Quartering Reduction Method
चतुर्थांश विधि (500 ग्राम तक कम करें)
Mix all 15 slices thoroughly in a clean plastic bucket. Spread into a flat circle, divide into 4 equal quarters, discard opposite two quarters. Remix remaining and repeat until exactly 500 grams remains.
Shade Drying & Moisture Free Packing
छाया में सुखाना और लेबल लगाना
Dry the 500g composite sample in shade on a clean plastic sheet. NEVER dry under direct sun or oven. Pack in a clean double plastic or cloth bag with the identification tag placed inside.
Mandatory Best Practices (क्या करें)
- •Sample soil 1 month prior to sowing or immediately after harvesting previous crop.
- •Use clean, rust-free stainless steel khurpi, auger, or spade and plastic buckets.
- •Take sub-samples from at least 10–15 spots across 1 acre in a zig-zag trail.
- •Clearly write farmer name, survey number, and proposed crop on two tags (one inside bag, one outside).
Critical Mistakes to Avoid (क्या न करें)
- •NEVER sample near bunds, field edges, tree shades, compost pits, or fertilizer bags.
- •NEVER sample immediately after chemical fertilizer, manure, or gypsum application.
- •NEVER dry soil sample under hot direct sun or bake in an oven; heat destroys microbial nitrogen.
- •NEVER use old fertilizer sacks (like urea or DAP bags) which contaminate the sample.
