Organic manure and fertilizer N management strategies improve soil health at different growth stages of pearl millet under pearl millet-wheat sequence.

ABSTRACT:

Background

Incorporating organic manure improves soil properties and crop productivity. A long-term study started in October 1967 examined the effects of farmyard manure and nitrogen fertilization on the soil at key growth stages of pearl millet in a pearl millet-wheat cropping system over its 51st cycle.

Results

Applying 15 Mg of farmyard manure (FYM) per hectare in both growing seasons significantly boosted soil organic carbon (SOC), dissolved organic carbon (DOC), and key nutrients compared to one-season application. SOC levels reached 9.1-11.0% with FYM₁₅, outperforming FYM₁₀ and FYM₅. The effectiveness order was FYM₁₅ > FYM₁₀ > FYM₅ > FYM₀. Chemical nitrogen fertilization also enhanced soil pro
