A field experiment was conducted on clayey soil at Kom AbouKhallad village, Nasser district, Bani-Suef Governorate, Egypt during
the winter season of 2014/2015. This study was conducted to identify the
effect of applied vermicompost at rates 2.5, 3.3 and 4 Mg fed-1,
magnetite at rates 100, 150 and 200 k.g fed-1 and Sugar industry wastes
(a mixture of the Filter Mud and Sugar lime wastes with a ratio of about
1:1) at rates 6.7, 10 and 13.3 Mg fed-1 as either solely or combined
treatments, on some soil properties as well as the vegetative growth,
nutritional status and yield of wheat (Triticum aestivum L. cv Bani-Suef
5). The suitability class of the used irrigation water is C3S1 (ECiw =
2.08 dS/m and SAR= 7.12) for Baha drainage water.
The obtained results of the investigated soil indicated that, the
values of EC, ESP and pH, were decreased with application of
vermicompost, magnetite and sugar industry wastes. These decreases
varied from treatment to another, the best treatment was found to be
(T10= filter mud + sugar lime (1:1) w/w (13.3 Mg fed-1) and T13= filter
mud + sugar lime (1:1) (6.7 Mg fed-1) + vermicompost) as compared to
the other combined or solely ones. However, the treatments effect on
OM% and CEC have the opposite trend since their combination caused
increase of OM and CEC values. Also, application of vermicompost,
magnetite and Sugar industry wastes were more pronounced in
decreasing soil bulk density, and increasing both hydraulic conductivity,
total porosity and soil moisture content values. The obtained data
emphasized that the achieved enhancing soil properties were positively
reflected on the nutrient contents of plant tissues and plant parameters.
(grain and straw yields).
So that, it could be recommended that applications of
vermicompost, magnetite and sugar industry wastes should be used to
alleviate the hazardous effects of a saline soil or saline irrigation water.
In addition, such favourable conditions should be enhance continuous
biological activity and nutrients slow release along the growth stages of
wheat plants, and in turn to minimize their possible losses by either
leaching or volatilization processes. This approach represents a best strategy in agriculture field that has a long-term positive agronomic
value and an effective practice of fertilization management on long-term.
