depletes the soil of nutrients
(making the soil less productive over time), reduces organic matter in soil and can cause significant erosion.

polyculture
system as compared to monoculture: Better nutrient utilization – nutrients not utilized by one crop will be beneficial to another crop in the crop rotation. … Higher crop resistance to plant pests – plants grown near each other are more immune to pests.

How is multiple cropping helpful?
Multiple cropping can
increase production and income
and has additional benefits—increased crop diversity, improved functioning of agricultural systems, spare land for biodiversity or other uses and reduced use of inorganic fertiliser and pesticides.
What are the 3 ways of planting intercrop?

Row intercropping
– growing two or more crops at the same time with at least one crop planted in rows. Strip intercropping – growing two or more crops together wide enough to permit separate crop machine production but close enough for the crops to interact.
