Abstract
 
The current work aims to evaluate the effect of different periods of organic farming on some soils qualities compared with the traditional system. Several farms varied in their soil nature and periods of practicing organic farming system were chosen. The farms are located in Belbes, El-Manayef, El-Fayoum and El- Behera areas. Moreover, the study also involved adjacent traditional managed farms. The evaluation was based on the weighted values of the physical, chemical and biological properties of the 0-50 cm and 0-100 cm soil depths. The considered soil properties weresoil organic matter (SOM); bulk density; porosity; available water; penetration resistance, mean soil particles weight diameter (MWD), cation exchange capacity and total microbial count. The obtained results indicated that soilbiological parameters were less important than the physical or thechemical factors. Principle component1, (PC1) scores indicated that 79.97% and 78.05 % of total variance are attributed to the 0-50 cm soil depth of the organic and conventional managed soils, respectively. In the meantime, 75.72 and 71.94 % are related to the 0-100 cm soil depth for the two farming systems, (Organic and conventional) in the same sequence. The only significantfactor contributing to PC2 was total count; PC2 indicatedthat (10.29 and 10.87% of the totalvariance are accounted for 0-50 and 0-100 cm soil depth of organic farming as well as 15.3 and 16.68% of the totalvariance for 0-50 and 0-100 cm soil depth of conventional farming system, respectively.
