NEET BIOLOGY

Detailed explanation-1: -Plant growth is affected by the amount of nutrients and moisture in the soil. High-quality soils contain a lot of organic matter, nutrients, and water. Soil quality is affected by farming practices. Plowing and tilling can disrupt soil structure as the soil is turned over for planting.

Detailed explanation-2: -In addition to erosion, soil quality is affected by other aspects of agriculture. These impacts include compaction, loss of soil structure, nutrient degradation, and soil salinity. These are very real and at times severe issues.

Detailed explanation-3: -They are water, light, nutrients, and temperature. These four things affect the growth hormones of the plant, which will either make the plant grow quickly or slowly.

Detailed explanation-4: -The impacts of intensive land use can cause compaction, erosion and the loss of soil carbon. This can reduce the biodiversity of soil, its health and productivity. Most human-caused erosion is due to pastoral farming. Soil from forestry land can also be eroded when forests are cut down and replanted.

Detailed explanation-5: -On the basis of soil parameters provided by HWSD seven key soil qualities important for crop production have been derived, namely: nutrient availability, nutrient retention capacity, rooting conditions, oxygen availability to roots, excess salts, toxicities, and workability.
