Abstract:
Soil samples were collected in the provinces of Hai Duong and Thanh Hoa, and in Ha Noi, Da Lat and Sapa cities. Each sample was taken from 9 spots of soil situated on 2 diagonals, that were mixed together. The chemical composition of the soil varied widely in different ecological areas. All the samples of soil showed light acid reaction, while those taken from Sapa (province of Lao Cai) were the most acid. Ha Noi soil samples were neutral. Almost soil samples were poor in total N, P and K, except that of Sapa, which was rich in N, while samples taken from Ha Noi and Thanh Hoa were the poorest. The total amount of P and K varied from poor to medium.
