Learn how to maintain soil health and combat degradation due to environmental and agricultural practices or natural disasters.
Soil health is an important aspect to consider when looking at the sustainability of an agricultural system. Learning about how to maintain soil health and combat degradation due to environmental and agricultural practices or natural disasters is critically important. By understanding the different factors that affect soil health, such as water availability, biological factors, physical structure, and chemical constituents, you can make educated decisions about sustainable land management practices.
In class 7 chapter 9, you’ll learn about the different soil types, their characteristics and how to identify them. You will also learn about techniques used for maintaining optimal soil health, such as nutrient cycling, soil erosion control and mulching. Finally, you’ll explore prevention and mitigation strategies for addressing environmental problems caused by poor soil health from overuse or lack of management. After studying this chapter, you'll be able to identify threats to soil health in your local area and discuss changes that need to be applied in order to preserve or improve the quality of our soils.
It is important to understand the fundamentals of soil health, as it directly relates to plant growth and crop yields. Soil structure and texture affects the amount of oxygen available for root growth, water infiltration and holding capacity, nutrient availability and pH levels. Additionally, nutrient cycling plays an important role in maintaining soil health. By understanding how to cycle nutrients within a system, you’ll be able to extend the longevity of agricultural landscapes by tackling problems such as soil erosion, compaction and drainage issues – preserving it for future generations
