reserve in soil organic matter. Most of the available sulfur removed by plants probably comes from the ester SO42- fraction although other organic sulfur compounds are also involved. Soil temperature Mineralization of sulfur is severely impeded at 10°C‚ increases with increasing temperatures from 20° to 40‚ and decreases at temperatures >40°C.This temperature effect on sulfur mineralization is consistent with the relatively greater sulfur content of soils formed in northern climates.

Homework 2.1.2.0 1. In addition to clay minerals‚ what other soil constituents contribute to total CEC? The Organic Matter present in the soil. 2. How does CEC buffer nutrient concentration in soil solution? CEC will exchange ions continuously between the solution concentration until both of the concentration has neutralized. 3. Why does anion adsorption appear to be of little importance in most agricultural soils? Why are AECs of ultisols usually greater than those of mollisols?

thick bark of the cork oak is stripped for making bottling cork. Forests help to conserve soil by preventing rapid runoff of water after heavy rain and minimizing flooding. Trees take in carbon dioxide and release oxygen into air‚ which is a great benefit to mankind. Forests influence local and global climate. The forest is also vital as a watershed. Because of the thick humus layer‚ loose soil‚ and soil-retaining powers of the trees’ long roots‚ forests are vitally important for preserving adequate

is the cheapest method of tsetse control especially when restricted application of insecticide is adopted [22‚ 26‚ 27]. In this case insecticide is sprayed on the legs and belly of larger/older cattle in the herd thus minimizing environmental contamination and cost of insecticide. Taking in mind that restricted or conserved areas are the main habitats [2‚ 28]‚ such method is not suited for use in long run. This is because conserved areas such as national parks and game reserves are legally cattle-free

regenerated naturally. It ’s a trouble due to the parts how the trees must play in stabilising the climate‚ atmospheric composition and soil structure. According to The Environ Facts 8 Feb. 1999‚ deforestation reduces the ability of the land to support life‚ affecting wild species‚ domestic animals‚ agricultural crops and people. The reduction in plant cover leads to accelerated soil erosion by wind and water. South Africa is losing approximately 300-400 million tonnes of topsoil every year. (Adams and Tisdale
