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 5 chemical properties of 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 is chemical properties of the soil?

The chemical properties of soil are the levels and availability of nutritional mineral elements for the plants, and the chemical parameters of soil in connection with their restoration or availability. The results on nitrogen and phosphorus are presented in detail.

What is physical properties of soil?

Physical properties of soil include color, texture, structure, porosity, density, consistence, aggregate stability, and temperature. These properties affect processes such as infiltration, erosion, nutrient cycling, and biologic activity.
