Weathering of K-bearing minerals as the major source of potassium in soils is of special importance under K deficient conditions. Many studies have been carried out on the effect of plant types and microorganisms on the transformation of micaeous minerals and their potassium release. However, there is no information on the effect of organic matter on mineralogical changes in micaceous minerals....

Organic acids, such as malic, citric, and oxalic, play important roles in agricultural soils. They can affect chemical and physical properties of the rhizosphere and therefore, increase cation and anion concentration in soil solution. This increases the uptake of elements by plants. A factorial experiment with a completely randomized design was conducted to investigate and compare the influence...
