Answer:
Crop intensification can be defined as the methodologies/procedures used to increase crop productivity (i.e., food, biofuel, fiber) in the same unit of land. These methods include relay intercropping, successions crops and the use of organic materials in order to increase the fertility of the soils (and therefore plant growth)
Explanation:
Crop intensification refers to the techniques used by farmers around the world aimed at increasing crop productivity (for example, wheat yield, cotton fiber production, etc.) These systems of crop intensification mainly include relay intercropping and successions crops, which increase the fertility of the soils (especially after oilseed crops) and crop resilience to climate change. The addition of organic material may also result useful to increase the plant growth (i.e., crop production) and agricultural sustainability by minimizing available resources such as, for example, water availability, chemical fertilizers, etc.
