Summary
Soil fertility and IPNS in Vietnam
Human activities in many cases strongly aggravated the disadvantages of the soil fertility. The most pronounced constraints to be addressed in plant nutrient management include inter alia: soil organic depletion, low CEC, phosphorus fixation, erosion, runoff and leaching. The main practices proposed for integrated nutrient management comprise: create a stable soil body with high carrying capacity, address phosphorus fixation, exploitation of biological sources of potassium, appropriate liming, diversification of farming systems, supply of multicomponent fertilizers and right use of fertilizers.
