The effect of long-term monoculture on chemical composition of soil organic carbon (SOC) remains unclear. This study was done to evaluate how changes in chemical compositions of SOC responded to long-term monoculture. To achieve this objective, the chemical compositions of SOC ...
Soil surveys were conducted to study the physico-chemical characteristics of major black pepper (Piper nigrum) growing soils in Kerala and their relationship with black pepper productivity. Soil samples were collected from four major black pepper growing districts, namely, Idukki, Wayanad (hi...
chemical compound,compound- (chemistry) a substance formed by chemical union of two or more elements or ingredients in definite proportion by weight soil conditioner- a chemical substance used to improve the structure of the soil and increase its porosity; "gypsum can be used as a soil conditione...
This fraction of soil consists of loose and friable particles of 2.203—.02 mm diameter. Sand particles can be seen by unaided eye. These particles, although inactive, constitute the framework of the soil. They play less important role in physicochemical activities. When coated with clay, these...
Our study further linked C (and N) enrichment and resulting depletion of mineral-derived cations within XPS analysis depth to the wetting properties as an important soil physical property that is relevant not only on the pedon but as well on the particle scale with distinct implications for ...

Acid sulphate soil (ASS) includes all the soils and materials in which, as a result of soil formation, sulphuric acid will be, is, or has been produced in amounts that have a lasting effect on the main soil characteristics [1]. The bulk of ASS has been geographically associated with mod...
The continuous flow of ozone gas into the dispersion of CNTs is designed to strip out the unstable hydroxyl species and weaken the p-type effect of CNTs through their extremely oxidative property, while forming highly stable carbonyl groups in the CNTs network. The electrochemical oxidation method ...
Oolong tea is famous for its characteristic of durably brewing. To explore suitable brewing cuppages and the scientific methods to brew Oolong tea in multiple steeping process. Dahongpao tea (Zhengyan, Banyan and Zhouyan tea) is well known Oolong tea variety, brewed at 14 times and assessed ...
