This approach often requires addition of natural and artificial fertilizers; whose adequate use necessitates agrochemical analysis of the soil on a regular basis. As a result of the unspecified and non-professional addition of mineral (organic) fertilizers and aiming to improve soil fertility, there has been balance disorder in the soil and its overload with certain nutrients. Thus, this study elaborates an agrochemical analysis of the soil in a greenhouse in which miscellaneous crops are cultivated, which has been treated with solid animal manure without any prior agrochemical analysis of the soil. Examinations have been made both of soil from the greenhouse and of soil in an uncovered parcel adjacent to the greenhouse, where crops have been cultivated as well. The soil samples were taken from three depths (10, 20 and 30 cm), unified by 5 separate samples. pH, electro conductivity, total amount of nitrogen, easily available phosphorus, potassium and humus have all been specified in these soil samples. A difference in the values of all parameters has been established in both covered and uncovered area, i.e. an increase in the values of the parameters in the covered area. From the analyses and the average values of all parameters, it has been established that the soil has fairly high pH values (8.41 in the greenhouse and 8.32 in the uncovered area), a medium level of total amount of nitrogen (1.66mg/100gr in the greenhouse and 1.3mg/100gr in the uncovered area), quite high concentration of phosphorus (50.72mg/100gr in the greenhouse and 47.23mg/100gr in the uncovered area), quite high potassium values (39.01mg/100gr in the greenhouse and 43.44mg/100gr in the uncovered area) and high values of humus (3.97% in the greenhouse and 3.29% in the uncovered area). On basis of the results obtained, it has been established that the soil is supersaturated with phosphorus and potassium and due to this, the soil itself cannot be fertilized in the following few years.
