INFLUENCE OF SOIL ORGANIC MATTER CONTENT ON SOIL

Soil Water. Most soil chemical properties are associated with the colloid fraction and affect nutrient availability, biota growing conditions, and, in some cases, soil physical properties. Biological properties in soil contribute to soil aggregation, structure and porosity, as well as SOM decomposition and mineralization. Organism activity is, In Demonstration 2, students examine soil properties such as soil horizons, texture, structure, color, depth, and pH in a large soil pit. Students and the instructor discuss how the soil properties observed affect the use of the soil for farm-ing, gardening, and other purposes. > SUPPLEMENTAL DEMONSTRATIONS AND EXAMPLES (1 HOUR).

Physical properties also influence the chemical and biological properties. The most pertinent physical properties of soil relevant to its use as a medium for plant growth are discussed in the The soil temperature greatly affects the physico-chemical and biological processes of the soil. Temperature of soil depends upon the temperature of atmospheric air and on moisture content. It is controlled by climate, colour of soil, slope, and altitude of the …

1/02/2017В В· Abstract. This chapter provides a basic description of soil properties and processes, stressing the concept that the soil is a dynamic entity where complex interactions among its biological, chemical and physical components take place. These soil properties are essential to crop production. Crop production potential is . greatly influenced by the phys-ical and chemical properties of soils. These same properties also influence related activities such as tillage, erosion, drainage, and irrigation. Important agronomic soil properties include the soil water-holding capacity
