Comparative effect of some industrial wastes as soil conditioners on some phyiso-chemical, hydro physical soil properties and maize productivity [electronic resource].

Includes references.

A field experiment was conducted at EL-Arish Agricultural Research Station, North Sinai Governorate for two successive summer seasons 2009 and 2010 to study the effect of the application of by -pass, sugar lime, vinasse and the mixtures of them on some phyisochemical, hydro physical soil properties and Maize productivity. The obtained data showed an improvement on the phyiso-chemical, hydro physical soil properties and corn production, with all treatments, due to increasing total porosity, fine capillary pores, available water, and water use efficiency while, bulk density, hydraulic conductivity, quickly drainable pores ECe and pH values have been decreased indicating an improvement on soil structure. Grain yield of maize was increased by using concerning amendments, particularly in the presence of the mixture (4) followed by the mixture (1) then the mixture (3). The application of the mixture (1) gave the highest profit followed by the mixture (2). According to the economic evaluation. Using mixture (4) in the light soils saved 343 m3 fed-1 of water. Almost 2x106 fed. of the Egypt's land area is comprised of the light soils, consequently led to save about 686x 106 m3 of water, at Using mixture (4). This quantity can be used to cultivate about 69x103 fed.
