Crop Rotation

Crop Rotation

The most basic form of crop rotation is also the simplest: never plant the same thing in the same place twice. A good crop rotation plan is a sort of seasonal dance in which the crops move from spot to spot, and it helps create a garden that is constantly new and intriguing.

The aim of rotation is threefold: to balance nutrient demands, foil insect and disease attacks, and deter weeds. Figuring out rotations, and finding an elegant solution to the puzzles of planning, can be fascinating work.

Nutrient Rotation

  • The challenge here is trying to balance the nutrient demands each crop makes on the soil.
  • Divide your crops into the following four types, for four different seasonal rotations:
    –Leaves: Thrive on nitrogen; examples include lettuce, salad greens, chicory, spinach, broccoli, Brussels sprouts, cabbage, cauliflower, kale and kohlrabi.
    –Fruits: Need phosphorus; examples include squashes, cucumbers, melons, pumpkins, tomatoes, peppers, and eggplants.
    –Roots: Love potassium; examples include onions, shallots, garlic, scallions, leeks, carrots, beets, turnips, and radishes.
    –Soil builders and cleaners: Legumes are excellent for the soil because because they store nitrogen from the air and release it into the soil; examples of cleaners include corn and potatoes, examples of builders include beans and peas.

    The first season of planting could be devoted to leafy plants, the next season to fruits, followed by the root plants and then legumes.

    Prevention Rotation

  • Crop rotation can also break the cycles of pest and disease problems that build up in soils planted repeatedly to the same crop.The idea is to plan your rotation so that no two crops subject to similar diseases follow one another within the disease’s incubation period. The same principle holds for insect pests: crop rotation makes it harder for emerging insects to find their preferred food each spring.
  • Plant Rotation List by Family
    –Squash: melons, squash, cucumber, and pumpkins.
    –Mustard: broccoli, Brussels sprouts, cabbage, cauliflower, kohlrabi, kale, mustard, radishes, and turnips.
    –Tomato: tomatoes, eggplants, peppers, and potatoes.
    –Beet: beets, spinach, and chard.
    –Legumes: beans and peas.
    –Onion: onions, leeks, scallions, garlic, and shallots.
    –Carrot: Carrots, dill, parsnips, and parsley.

    not only does crop rotation contribute to maintaining the appropriate balance within your soil, it also keeps it from eroding. When you have strip crops, such as corn, the wind tends to blow down the center of the rows, causing the un-used soil to blow away. So, the next year you may want to plant a solid crop, such as alfalfa or barley. You could possibly plant soybean, it is planted in small rows but there is little space between. We are really hitting this topic in my Wildlife class at my high school, and it has really made me consider jus how important crop rotation really is.
