Question

Explain how unscientific agricultural practices can reduce the fertility of the soil?

Answer 1

Unscientific agricultural practices can reduce the fertility of the soil

Explanation:

• Poor agricultural practices cause soil erosion causing flooding, water pollution and agricultural waste. Soil loss, increased floods, and contamination of dams by fertilizers and crop waste, could all be stopped if unscientific agricultural practices are stopped
• For example, unscientific agricultural practices like shifting cultivation can lead to decline in soil fertility. Shifting agriculture  is a method of growing food wherein wild/forested land is clear-cut and the remaining vegetation is burned. The leads to an environmental mess such as soil erosion, loss of forests, and release of pollutants into the atmosphere.
• Another practice is Intensive farming where a lot of labour and money  are used to raise the yield which can be got per land area. The use of large quantities of pesticides for crops and medication for livestock (farming animals)is common, Excessive pesticides affects the fertility of the soil

Answer 2
