Soil reaction (pH) • Soil reaction is the pH (hydrogen ion concentration) of the soil. • Soil pH affects crop growth and neutral soils with pH 7.0 are best for growth of most of the crops • Soils may be acidic (<7.0), neutral (=7.0), saline and alkaline (>7.0) • Soils with low pH is injurious to plants due high toxicity of Fe and Al.

www.ijsrp.orgThe soil bulk density was selected as dependent variables to determine statistical relationships of soil texture, organic matter content and nutrient concentrations with soil bulk density. Factors affecting bulk density are Porosity, Texture and Organic matter content. Clay soils tend to have a higher total porosity than sandy soils.

www.extension.uidaho.eduIn addition to pH, temperature is a critical factor affecting the balance between these microbial populations. Sudden changes in temperature adversely affect the methane formers, thus affecting the acid formers, too. Any change having an adverse effect on the methane formers increases acid concentration, which in
