Improving soil fertility and fodder sources on 80% sand!

26 May

The combination of no-till (no soil disturbance) and a high and diversified biomass inputs improve the soil fertility even on 80% of sand. Soil analysis are conducted at the Tokyo University of Agriculture and Technology and at the Royal University of Agriculture in Phnom Penh.

High biomass inputs buffer the soil temperature, increase the soil water holding capacity, increase the soil organic and nitrogen concentrations and enhance the soil biological activities that is largely involved in nutrient cycling, pest and diseases regulations.

Animal husbandry is one of the main components of the rice farming system and cattle and buffalo are in a constant state of undernourishment as they rely on poor-quality roadside grasses and rice straw as their primary source of nutrition. In addition, farmers have to travel long distances to ‘cut and carry’ roadside grass or care for animals grazing rice stubble. Our work emphasized that we can produce fodder sources (stylo and centro, two tropical legumes) after rice on the soil residual moisture producing from 10 to 20 tons of fresh biomass.

Significant improvements in the rice production systems, that is, higher resilience to drought and flooding, are crucial and should be based on diversification of non-rice crops and/or establishment of fodder legume species after wet season rice, while always improving income, food nutrition, soil fertility and fodder resources.
