Final answer:
Some reasons for soil deterioration include pesticide resistance, increased salts in the soil, nutrient-poor soils, blight, and desertification.
Step-by-step explanation:
Reasons for Soil Deterioration are-
Pesticide resistance: Excessive use of pesticides can lead to the development of pesticide-resistant pests, which can destroy crops and harm soil quality.
Increased salts in the soil: Over-irrigation or the use of salty water for irrigation can lead to a buildup of salts in the soil, making it inhospitable for plant growth.
Nutrient-poor soils: Poor agricultural practices, such as the continuous monoculture of crops without proper soil replenishment, can deplete essential nutrients in the soil.
Blight: Plant diseases like blight can spread rapidly in soil, causing widespread damage to crops.
Desertification: Overgrazing, deforestation, and unsustainable agricultural practices can lead to the conversion of fertile soil into desert-like conditions.
