rock phosphate bentonite
Influence of Kaolinite Clay Supplementation on Growth
22/04/2016Bentonite is a rock constituted of highly colloidal plastic clays composed mainly by montmorillonite ( Safaei et al., 2014 ). The particular characteristic of bentonite is its capability to form gel with water and its high cation exchange capacity (about half the CEC of zeolite clay).

Interaction Between Halotolerant Phosphate
16.12.2021Rock phosphate (RP) is a raw material used in manufacturing phosphatic fertilizers; it has been used as an alternative P source extensively due to its lower cost and as a support for sustainable agriculture (Xiao et al., 2011). However, the extremely poor solubility of RP limits its direct use as a soil amendment, especially in saline–alkaline soil. Previous studies have
