The Lankaran province is a humid subtropic region in Azerbaijan. It is a foremost region in tea, citrus, grain, vegetable plants production. We have performed long researches in the soils under tea and vegetable cultures of the Lankaran province, a modern fertility level of the soils under tea and vegetable cultures has been determined on the basis of the references- fund materials and private researches. Evaluation of the soils under tea and vegetable cultures by quality was carried out based on the obtained initial information and the weak podzolic yellow soils were selected for the soils under tea, the humic- boggy soils were selected for the soils under vegetable (100 scores), the bonitet scores of the other soils were fixed in comparison with them. Then an average account bonitet score of the soil diversity was calculated, an average account score of the tea lands was 76 scores, but an average account score of the vegetable lands was 78 scores. The agroproduction grouping of the soils under tea and vegetable cultures was performed in the Lankaran province: the 1 st group –an area of the high qualitative soils under tea culture is 53,5%; but it is 20,75% in the soils under vegetable culture, the IV group-lower qualitative soils are used under tea culture (4, 46%), but they aren’t used under vegetable.
