How is crop rotation good for the environment?

Crop rotation practices can result in increased soil carbon content through high crop cover periods, reduced frequency and tillage intensity. Increase in the use of forages in crop rotations can result in better crop residue management while higher soil-carbon content helps combat climate change.

What follows onions in crop rotation?

Area 1: Enrich area with compost and plant potatoes and tomatoes (Solanaceae). When crop has finished sow onions or leeks (Allium) for an overwinter crop. Area 2: Sow parsnips, carrot, parsley (Umbelliferae). Fill gaps with lettuce and follow with a soil-enriching green manure during winter.

Crop rotation helps return nutrients to the soil without synthetic inputs. The practice also works to interrupt pest and disease cycles, improve soil health by increasing biomass from different crops' root structures, and increase biodiversity on the farm.

Is crop rotation good or bad?

Crop rotation also helps to battle against the forces of erosion. Rotating crops helps to improve soil stability by alternating between crops with deep roots and those with shallow roots. Pests are also deterred by eliminating their food source on a regular basis.
