- Abstract
Organic agriculture is considered to be a durable system, in which the manure utilization assures a high quality of the production obtained and also of the soil's properties. Through application of high quantities of the organic fertilizers, in dozes of 50t/ha and 100 t/ha of manure, comparatively with variants fertilized with NPK and unfertilized variants, results showed an improvement of the soil's properties to all cultures as fallowed: pea-beans, wheat, potato and maize. The results obtained on argic phaeozem revealed that 50 t/ha manure applied on soil lead to increased the hydro stability of the soils aggregates between 5 and 8%, increased values of wilting point coefficient and also the pH values between 0,5 and 1 to all cultures. A higher quantity of manure, 100 t/ha has not showed high differences compare to witness regarding the aggregate stability and led to increase of the CO values, which means a negative effect during the drought season when plant cannot take the water from showers, which will be held from soil. Regarding the organic matter content, the values were different depending on culture and their efficiency to use manure. Thus, the differences between witness and 100 t/ha manure variant were the highest, at pea (2.12) and wheat culture (1.76).
