What is Crop Rotation?

Definition: Crop rotation is the practice of planting different type crops on the same piece of land each successive growing season.

Purpose: It helps prevent soil diseases, insect pests, weed problems, and builds healthy soils.

·         Improves soil's moisture absorption, reducing freshwater exploitation.

·         Decreases soil erosion and enhances fertility levels.

·         Prevents nutrient depletion caused by overproducing one crop.

·         Returns nutrients to the soil without synthetic inputs.

·         Interrupts pest and disease cycles.

·         Increases soil health by enhancing biomass from different crops' root structures.

·         Boosts biodiversity in the garden.

 

Serious home gardeners can consider practicing a four-year crop rotation cycle, alternating between:

1)      Legumes such as peas, green beans, soybeans, peanuts, alfalfa and fava beans.

2)      Greens and Brassicas including kale, broccoli, cauliflower, cabbage, herbs, lettuce, and other leafy greens.

3)      Fruiting Vegetables like tomatoes, squash, cucumbers, melon, peppers, eggplant, and potatoes.

4)      Root Vegetables such as turnips, radishes, beets, garlic, onion, leeks, parsnips and carrots.

Sample Four Year Crop Rotation Schedule

In a four-year crop rotation, when you start the cycle doesn’t matter, but the ORDER does.

Year One - Legumes fix nitrogen from the atmosphere, adding to the soil.

Year Two - Greens and brassicas then utilize a lot of nitrogen to support their leafy growth. By using up some nitrogen, the greens are also preparing the soil for the next group.

Year Three - Fruiting vegetables need ample phosphorus to develop flowers and fruit (and will focus too much on leafy green growth instead of fruit if they’re provided too much nitrogen).

Year Four - Root vegetables are the least heavy feeders, but perform best with more potassium and phosphorus than nitrogen. Then the cycle starts all over again with nitrogen-fixing legumes.

Keep Track of Crop Rotation 

The most difficult part of practicing crop rotation can be keeping track. Use a planner, spreadsheet or chart to record what you’re growing in each bed every season. Makes it super easy to plan ahead for future planting by referring back to previous years efforts.
