Phosphorus Changes In Intensive Cropping Paddy Soil Under Natural And Controlled Conditions From Mada, Kedah

Phosphorus is one of the primary nutrients needed by plant to perform its activities. However, phosphorus in soil can easily being fixed. In agricultural soil, phosphorus was mainly supplied by fertilizer application. Majority of farmers tend to apply more phosphorus fertilizer to increase yield and...
