write a short note on soil resources
Answers
Answer:
Explanation:
→ The coverage of Earth’s surface with soil varies from place to place. Tropical forests have thin soils that are poor in nutrients, while grasslands in temperate regions have soils that are rich and well able to support crops. There are several different classes of soil depending on how the soil is formed and where it is located. An understanding of which class of soil is found in a particular location is an important foundation to obtaining successful crop yields.
Soil resources need conserving as much as water resources do. Erosion is the key process by which soil is created from rock and destroyed. Wind and rain are the main factors that cause erosion of soil from agricultural areas, possibly converting them into new desert. Some modern agricultural practices leave soil exposed to the elements and thereby risk loss of long-term productivity because of soil erosion.
Soil resources are a form of environmental asset providing a range of ecosystem services. A key feature of soils is their delivery of supporting services including the formation of and function of the soil itself, nutrient cycling, water cycling, structural support of vegetation and soil biodiversity. Advances in watershed, natural resource, and environmental sciences have shown that soil is the foundation of basic ecosystem function. Soil filters our water, provides essential nutrients to our forests and crops, and helps regulate the Earth's temperature as well as many of the important greenhouse gases.
