Plant growth requires nutrients and their functions in plants cannot be replaced by other elements so that if there are not enough nutrients in the soil, plants cannot grow normally. The nutrient content in the soil and the ability of the soil to provide nutrients for plant growth is different. So that the type of fertilizer and the amount of fertilizer given to each type of soil will be different and it depends on the type of plant being cultivated. To determine the requirements of fertilizers and the types of fertilizers required for each type of soil, need some research about the evaluation study of soil fertility. The research was conducted in Aceh Besar with located between 5¼ 2 ‘-5¼ 8’ N and 95¼ 80 ‘-95¼ 88’E. Assessment of soil fertility status based on the criteria of several soil chemical properties, CEC (cation exchange capacity), alkaline saturation, C-Organic, P2O5 (HCL, 25%) mg / 100g, and K2O (HCL, 25%) mg / 100g. The analysis results obtained from 11 sample points show that Aceh Besar has soil fertility status from medium to low.
