What are the chemical properties of the soil?
Soil chemical properties, including heavy metal concentrations, pH, total carbon, total nitrogen, CEC, exchangeable calcium (Ca), magnesium (Mg) and potassium (K), exchangeable Al and hydrogen (H) and available phosphorous (P), were determined following standard laboratory methods.
What are the three main chemical properties of soil?
Chemical properties of soils include the following aspects: inorganic matters of soil, organic matters in soil, colloidal properties of soil particles and soil reactions and buffering action in acidic soils and basic soils.
How many chemical properties does soil have?
The Chemical properties of soils includes (1) Inorganic matters of soil , (2) Organic matters in soil , (3) Colloidal properties of soil particles and (4) Soil reactions and Buffering action , (5) Acidic soils and (6) Basic soils. This module highlights the major chemical properties of soils.
What are physical and chemical properties of soil?
A soil’s physical and chemical properties affect plant growth and soil management. Some important physical and chemical properties of soil are mineral content, texture, cation exchange capacity, bulk density, structure, porosity, organic matter content, carbon-to-ni- trogen ratio, color, depth, fertility, and pH.
What are the most important chemical properties of soil?
Soil pH. Soil pH is perhaps the single most important aspect of soil chemistry, because it affects the availability of nutrients to plants and the activity of microorganisms in the soil. Soil pH is a measure of the number of hydrogen ions (H+) present in a solution.
What is the most important chemical property of soil?
How do chemical affect the soil?
The presence of a number of acids in the soil, such as hydrochloric and sulfuric acids, creates a damaging effect on soil referred to as soil friability. As the chemicals in the chemical fertilizers destroy soil crumbs, the result is a highly compacted soil with reduced drainage and air circulation.
What are the 5 properties of soil?
All soils contain mineral particles, organic matter, water and air. The combinations of these determine the soil’s properties – its texture, structure, porosity, chemistry and colour.
