Soil Test Interpreter
Interpret your soil-test report — pH, organic carbon, N, P, K — into Low/Medium/High ratings and plain-language fertilizer guidance.
The ±25% adjustment is the standard soil-test-based correction used by Indian soil testing labs on the general recommended dose for your crop and region.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.

Frequently asked questions
What do Low, Medium and High mean in a soil test?+
They are ratings against established critical levels: Low soils need the full or boosted nutrient dose, Medium need the standard recommendation, and High soils can have the dose reduced. The cut-offs differ for N, P and K.
How is soil organic carbon related to nitrogen?+
Organic carbon is the practical proxy for a soil's nitrogen-supplying power, since most soil nitrogen is held in organic matter. Low organic carbon (below ~0.5%) signals a Low nitrogen soil that needs a higher urea dose.
