Soil acidity is associated with the presence of hydrogen and aluminum in exchangeable form. Since soil acidity is a condition that results from prolonged leaching of soluble salts, soils in humid areas are usually acidic. The concept of acidity was developed in connection with the behavior of ...
High soil CEC translates into a soil with high buffering capacity, signifying that addition of acidic or basic components has a smaller effect on soil pH at least up until a certain point (Granatstein et al., 2009). For instance, a high CEC soil will take a longer time to develop into...
Soils become extremely acidic (pH < 4) when the presence of large amounts of reduced forms of S are oxidized to H2SO4 if the soils are exposed to oxygen when they are drained or excavated. With a ≥ 0.15 m thick sulfuric horizon that is often present, such soils are commonly referred...
Crop rotation or mixed cropping can improve the fertility of the land. Solid waste treatment Proper methods should be adopted for management of solid waste disposal. Industrial wastes can be treated physically, chemically and biologically until they are less hazardous. Acidic and alkaline wastes ...
The soil is an acidic, loamy clay derived from Quaternary Red Clay and classified as a Ferralic Cambisol51. Before the establishment of this experiment, the site was a mass pine (Pinus massonina Lamb.) natural secondary forest. The field experiment compared three crop systems based on common...
(Brady & Weil 2008). Aluminum toxicity is also a common problem for crop growth at low pH (<5.5). Typically, soil pH values from 6 to 7.5 are optimal for plant growth; however, there are certain plants species that can tolerate — or even prefer — more acidic or basic conditions. ...
The infrared spectrum of a mineral is a characteristic feature, which permits the identification of mineral species. The absorption bands arise from vibrations of the atoms or ions in the structure, and the frequencies of vibrations are dependent on the
Soil can be acidic.neutral.or basic.The pH of the soil is determined by the nature of the rockfrom which it was formed.and by the nature of t}le plants that grow and rot in it. The acidity of rain and snow can lower the pH of the groundwater that enters the soil.By burning foss...
Similarly, as for dryland soils, GPR surveys are more successful in peats with sandy subsoils and are even more successful in acidic peats lacking clays and exchangeable cations. The electrical conductivity of clays can cause electromagnetic signal attenuation and can be accentuated by a high cation...
acidic, fungal-dominated humus materials of slowly-decomposing litters and more common in the less acidic, bacterial-dominated richer soils of rapidly decomposing species. Indeed, the chemical and physical characteristics ofplant litterhas proven to be more important than climate or any other source ...
