The current study was carried out to evaluate certain non-conventional techniques including the use of organic manures, either residues left from soaking cattle and chicken manures applied to the soil or spray of their extracts on the plant biomass; biofertilizers as well as natural resources of rock phosphate were also used, inorganic fertilizers being included for comparison. Such evaluation was thought to be performed through evaluating responses of soil characteristics represented by both chemical characteristics and element availability; responses of developed plants to applied treatments were thought to be not included in the present study. This study was conducted under conditions of greenhouse located in Soils Department, Faculty of Agriculture, AinShamsUniversity; it represents the application of results obtained from the two pot experiments previously conducted. Cucumber seedlings of 15 days old were planted after being inoculated with liquid culture of the used biofertilizers and let to be grown three months up to harvest. The studied soil samples were taken out before flowering stage of grown cucumber plants to evaluate the concerned responses of the indicated soil samples. Results showed that organic manure application practices were favorable compared to either original untreated soil or inorganic control treatments; application of the used biofertilizers added, either separately or in combinations, to manuring was favorable for most of the studied parameters, application of rock phosphate to the mentioned treatments being also favorable.
