Soil and Nutrient Management
Agricultural lands in Southeast Asia are predominately occupied by small-holder farmers, who have limited resources and capability (knowledge and technology) to manage the soils efficiently to optimize crop production.
Current land use practices together with harsh climatic conditions and population pressure have led to soil degradation, loss of soil fertility, declining crop yields and malnutrition, subsequently declining in livelihood. An enhancement in productivity of food crop is unlikely to be achieved without ensuring that crops have adequate and balanced supply of nutrients.
Sustainable agricultural system is based on managing soil according to their constraints and thus capabilities. Rehabilitation of the productive capacity of soil for crop production is the key issue to be addressed in ASEAN Sustainable Agrifood Systems (ASEAN SAS). If soil quality is poor, it cannot function effectively thus incapable to sustain a productive agriculture. This could be achieved through integrated approach to conserve and manage soil and nutrient. Accomplishing this could have enormously impact on sustainability of agriculture and food production in the region….
