Conservation agriculture improves yield and potassium balance in intensive rice systems
Intensive rice-based systems are mining soil potassium (K) due to negative K balances. Conservation Agriculture (CA) practices may increase yield and economic return of rice-based systems but there is limited ...

Conservation agriculture in intensive rice crop** reverses soil potassium depletion
Intensive crop** in the Eastern Gangetic Plain has progressively depleted soil potassium (K) over time due to negative K balances. There is limited understanding of how alternative soil and crop management p...
