أثر ملوحة مياه الري و المخلفات النباتية في بعض صفات التربة

Abstract EN

field experimental was conducted at Horticulture research station in Mahaweel during autumn season 2014-2015 in a loam clay sandy soil , using Systematic arrangement design of whole-plots with three replication .

Main treatment was three levels of irrigation water ( 1.4 , 5.0 , 7.0 dS m-1) while the sub-treatment had five levels of plant waste, which a comparison , rice husks (10 tons h-1), wheat straw (10 ton h1), the ashes of the husks rice (3.3 ton h-1) , the ashes of straw of wheat (2.5 ton h-1) and three interaction.

A field experiment to find out the effect of different irrigation water quality and five levels of plant waste on some chemical properties of soil , the results showed , the increase in the values of Electrical conductivity of irrigation water from 1.4 to 5 and 7 dS.m-1 led to obtain a significant increase in the values of Electrical conductivity of the soil from 2.84 to 6.38 and 8.78 dS m- 1 respectively.

The low degree of interaction of soil from 8.00 to 7.84 and values 7.69 respectively led to a significant increase in the positive and negative ions concentration dissolved in the soil.

The plant waste, particularly rice husks and straw of wheat have significant effect in lowring the rate of Electrical conductivity of the soil, reducing the values of positive and negative ion in the soil and reducing the harmful effect of salts in the root zone as a result of improving the physical properties of the soil
