CA is a sustainable agriculture practice that is proven to help improve soil health. The three principles of CA include minimal mechanical soil disturbance (i.e., no tillage), permanent soil organic cover and species diversification.CA/SI improves soil fertility, reduces labour, conserves water, increases yield, sequesters carbon from the atmosphere, and increases smallholder farmer’s income. As such, to fulfill one of the principles of cover crop, there needs to be a constant supply of cover crop seed. However, cover crop is yet to be commercially available to the Cambodian farmers.
So far, SmartAgro has produced about 30 tonnes of 12 varieties of cover crops seed, which can cover 1,500 ha of farmland area.
