Shri Poshan
Precision macro/micro nutrient orchestration
Origin & History
The nutrition layer, decoded.
Poshan (पोषण) means 'nourishment'. India's Soil Health Card scheme (2015) revealed widespread Zn, B, Fe, S deficiencies — yet farmers still apply uniform NPK. Shri Poshan layers ICAR-IISS leaf-analysis protocols on top of soil-health-card data to prescribe a per-field, per-stage nutrient orchestration that uses 30% less fertiliser for 15% more yield.
The Science
Soil samples are analysed for 12 parameters (N, P, K, S, Zn, B, Fe, Mn, Cu, OC, pH, EC). Leaf tissue is sampled at critical growth stages — DRIS (Diagnosis and Recommendation Integrated System) indices flag the most-limiting nutrient. Prescription: micronutrient foliar spray or fertigation event.
Crop Applications
How Shri Poshan shows up in the field.
Each crop responds differently to nutrition-layer intelligence. Validated across ICAR + state agri university pilots.

Sugarcane
K + S at grand-growth stage lifts cane weight by 11%.

Banana
Bunch-grade B foliar spray prevents bunch-stem cracking.

Tomato
Ca foliar spray reduces blossom-end rot by 80%.

Wheat
Zn foliar spray at booting boosts grain protein 1.2 points.
Practices across States

Farmer Benefits
What the farmer takes home.
Shri Poshan translates field intelligence into bankable, measurable, daily outcomes — without locking the farmer into proprietary inputs.
Fertiliser cost down 25–30% with same or better yield
Hidden-hunger fixed → grain protein, fruit quality up
Less nutrient runoff → groundwater nitrate down
Custom blend strategies for FPOs at scale
