Question

What is the percentage of phosphorus available in FYM ?

Hint:

Note: FYM enriches the soil with nutrients while also improving soil texture and water retention.

Answer 1

Farm Yard Manure (FYM) serves as a significant organic nutrient source in agriculture, contributing to soil fertility maintenance. On average, FYM comprises approximately 0.5% to 0.8% phosphorus (P2O5) by weight. Actual phosphorus content fluctuates based on livestock type, feed, bedding material, and manure management practices (storage and composting). Phosphorus from FYM is released gradually, enhancing its availability to crops. Beyond phosphorus, FYM supplies nitrogen, potassium, micronutrients, and organic matter, benefiting soil structure and microbial activity. Consistent FYM application decreases reliance on synthetic fertilizers and supports sustainable agricultural practices.
