The suetability of important soils in the Democratic Republic of Vietnam for growing coffee
The evaluation of earlier studies on the profile depth and and on the physical and chemical properties of important soils of the Democratic Republic of Vietnam as to their suitability for growing coffee led to these results: 1. Because of their physical features ferrallitic and fersiallitic soils are particulary well suited for growing coffee, whereas vertisol-like and groundwater-affected soils are less or not suited. 2. Within the group of ferrallitic and fersiallitic soils, physical and chemical soil properties suggest the following arrangement indicating decreasing suitability: basaltic soils - mountainous soil on granite - limestone soil - slate soil - soil on sandy porous sediments. 3. Contrary to the present practice of fertilizing in the Democratic Republic of Vietnam the chemical properties of the soil would make K fertilization more important than P fertilization in growing coffee
