Part of the model for recommendation for usage of P fertilizer is investigated. The differences in the coeficients in the parabolic equation are discussed for two soil tipes. The relation is between added P fertilizer and the phosphate capacity in the soil. The results proved that the soil type is significant in the transformation of added P in the soil, especially the soil properties conserning the sorbtion as pH and P sorbtion capacity. This reflects in the coefficient in the used equations.
