Textured Soil: soil is loose, very friable, and individual sand grains can be seen or felt. Soil organic matter: all organic matter in the soil, including humus, microbial biomass, and plant and animal residues in various stages of decomposition. Relative amounts of sand silt and clay in a soil. Micronutrient Transformation in To increase carbon sequestration in soils in the dryland and tropical areas, as a contribution to global atmospheric CO 2 mitigation, new strategies and new practices in agriculture, pasture use and forestry, including conservation agriculture and agroforestry, are essential. The effective control of the soil borne pathogens is possible only through detailed study on survival and dissemination of these pathogens. Physical Properties. MANY tropical soils are poor in inorganic nutrients and rely on the recycling of nutrients from soil organic matter to maintain fertility. - Chapter 37 Soil and Plant Nutrition * Figure 37.10 The roles of soil bacteria in the nitrogen nutrition of plants. It involves inoculation of beneficial microorganisms that help nutrient acquisition by plants through fixation of nitrogen, solubilization and mobilization of other nutrients. - Soil What is soil?

Chemical Properties. •Permeability is the ease in which water, air, and plant roots move through the soil –Ease of air, water and root movement –Affects rate of water intake and drainage •Porosity and permeability are affected by soil texture, structure, organic matter and compaction Soil is the most important natural resources and its fertility and quality indicator for sustainable crop production. There are 17 essential plant nutrients, three come from air and water (carbon, oxygen, and hydrogen) and 14 come from the soil. The table below describes the essential and beneficial elements obtained from the soil. Drains well, soaks up rain with little runoff. Soil organic matter is the backbone of nitrogen supply in organic production, and cultural practices to manipulate nitrogen start with building soil organic matter.

The role of organic matter in soil fertility BY E. W. RUSSELL Department of Soil Science, University of Reading Soil organic matter is a very heterogeneous mixture of substances, ranging from plant and root fragments, through the living bodies of the soil organisms, to brown amorphous humic substances produced by their activity. Farm animals manure (cow, pig) is a good option here. Content of January 29 meeting -3. The effective control of the soil borne pathogens is possible only through detailed study on survival and dissemination of these pathogens. Soil What is soil? Grazing land: this is land used for grazing cattle and sheep. Management of soil organic matter, 22 primarily through the use of short-term leys, helps ensure good soil structure and 23 biological activity, important for nutrient supply, health and productivity of both 24 crops and livestock. Iron bacteria (micro organisms) play a major role in transformation  Bacteria & fungi oxidise ferrous state to ferric state.
