There are many positive sides of crop rotation. Rotating crops among the beds of a backyard garden is actually an important and interesting practice, and also one that we needed to adopt in our garden.

 Disease Control

Many diseases and pests tend to affect plants of the same types. Rotating crops reduces the likelihood of diseases which can remain in the soil. For example, tomatoes, peppers, eggplant and potatoes are in the Solanaceae family and have similar susceptibility to diseases. If a gardener wants to rotate crops, any of the plants in this family should not be planted where other members were grown in the previous season.

Nutrients

Different plants use different amounts of nutrients from the soil. A crop which requires a high amount of a particular nutrient from the soil — for example spinach’s need for boron — could eventually lower the levels of that nutrient and then not do as well in that area.

The other example most people are somewhat familiar with is how legumes like beans and peas fix nitrogen in the soil. It makes good sense to alternate them with other plants that can take advantage of that nitrogen.

Soil Improvement.

Rotating crops can also improve soil structure by alternating deep rooted plants with shallow rooted plants.If you’ve already planted your veggies for the year, suggestions to consider rotating your crops are coming a bit late. However, you might need a little time to think about your practices and your willingness to make changes.

If you are considering making changes next year, you can make a map or diagram of what you planted in which spots this year. It’s a good idea to keep those garden plans so you can compare them year to year.
