How do conservation tillage practices lead to agricultural sustainability? a. conservation tillage practices reduce the amount of water required to grow crops. b. conservation tillage practices reduce soil erosion and maintain soil nutrient levels. c. conservation tillage practices naturally protect crops from insect damage, reducing the need for pesticides. d. conservation tillage practices reduce the amount of energy needed to produce crops.

b.  Conservation tillage practices help reduce soil erosion and maintain soil nutrient levels.

Explanation:

The tillage refers to the turning the soil up and down so as to prepare the soil  for sowing seeds and controlling the weed population. Conservation tillage is a sustainable practice for retaining the quality of the soil so that it can be used for the growth of the crops in future. In this method the stalks and stubble are left on the agricultural land after harvesting the crops so as to prevent the soil erosion.

On the basis of the above description,  b.  Conservation tillage practices help reduce soil erosion and maintain soil nutrient levels. is the correct option.
