Frequently Asked Questions
Why is crop rotation important?
Crop rotation prevents soil-borne diseases, reduces pest buildup, balances soil nutrients, and improves soil structure. The same crops in the same spot deplete specific nutrients and allow disease organisms to build up in the soil.
What is the basic 4-year rotation?
A classic 4-year rotation: Year 1 - Nightshades (tomatoes, peppers), Year 2 - Legumes (beans, peas) to fix nitrogen, Year 3 - Brassicas (broccoli, cabbage), Year 4 - Root crops (carrots, beets). Then repeat.
How many years between the same crop?
Most experts recommend 3-4 years between planting the same crop family in the same location. Nightshades and brassicas need at least 3 years due to persistent soil diseases like blight and clubroot.
