Impact of applied natural and organic amendments on improvement some properties and productivity of sandy soil [electronic resource].

Includes references.

A field experiment was carried out on a newly reclaimed sandy soil under sprinkler irrigation at Ismailia Agricultural Research Station, with peanut plants (Arachis hypogaea) Giza 5 cultivar, during 2009, to assess the effect of (compost, FYM) and (gypsum and bentonite shale) with zinc and boron as micronutrients on some hydrophysical and fertility status of sandy soil (bulk density, total porosity, hydraulic conductivity, moisture constants and nutrients retained) at maximum vegetative growth stage (90 days after sowing) as well as vegetative growth, yield and its attributes of the studied crop, i.e., seed& foliage yields, weight of 100 seeds, seed oil, protein and N, P, K, Zn, and B content. The applied rate of organic soil amendment individual or in combined treatments was 12.5 tons fad⁻¹., and inorganic one at a rate of 10 ton fad⁻¹., which were thoroughly mixed with the 5 cm soil surface layer. The applied rates of zinc and boron as micronutrients individual or incombined treatments were at a rate of 500 g fad-1' as foliar application at two times. The results obtained indicated that the applied inorganic soil amendments (compost or FYM either individual or in combined treatments zinc+boron) showed significant and positive improvements in both soil characteristics and the grown peanut yield parameters under investigation, with a significant superior for the combined treatments.
