From the perimeter of the agricultural holding, soil samples were collected under study in order to establish the state of soil fertility. The limiting factors of the soil fertility were identified. The production capacity of soils is influenced by a series of limiting factors, among which the most representative are: soil reaction, humus reserve, and the low content of nutritive elements. Depending on the restrictive elements presented, calcium amendment measures, ameliorative fertilizing, works to correct the aero hydric regime of the soil, and the professional application of agricultural technologies are required for intensive exploitation of agricultural land in ecological parameters. On the evaluated soils there can be observed an acidic and very acidic reaction which has started to block phosphorus. For now, the potassium levels are very good but the acidification process will continue, because calcium is being utilized as food, and is being consumed from the superficial layer, which causes the soil to continuously acidify. Acidification also occurs from most acidifying fertilizers. Acidic soils are soils lacking in basic cations and the colloidal complex transfer - the soil solution that is unfavorable for plant nutrition. As a result, it is recommended that the basic fertilization, when preparing the land, be carried out with manure, a complex fertilizer that improves activity in soil microbial life and nutritive elements in the soil
