UTILIIZATION OF ORGANIC AMENDMENTS TO REMEDIATE CHEMICALLY POLLUTED SOIL AND REFLECTION ON PLANT GROWTH

Abstract

This study was carried out in a pot experiment placed at private farm in Shibin Elkom, Menoufia Governorate, Egypt, during growing summer season of 2018 to evaluate the effect of some soil organic amendments on plant growth and nutrients and heavy metals uptake as well as soil chemical properties and its content of available heavy metal in two polluted soils. The conclusions extracted from this study can summarized in the following points: 1- Applications of soil organic amendments improved some soil chemical properties such as soil EC, CEC and the content of OM. 2- Applications of soil organic amendments (compost and biochar) improved plant growth and remarkably stimulated fresh and dry matter yields. 3- Plants content of N, P and K significantly promoted with compost and biochar applications. 4- Elevating rate of added compost and biochar augmented soil content of available heavy metal that may be enhance their uptake by plants (sugar beet) consequently remove it from the contaminated soils. 5- Applications of soil organic amendments increased plant concentration and uptake of heavy metals consequently it could be utilizing as a remediated in removing heavy metals from the polluted soil.
