Crop Rotation

Benefits of the specific technology to the community

From the Pan Germany Website:

  • Prevents soil depletion
  • Maintains soil fertility
  • Reduces soil erosion
  • Controls insect/mite pests. Crop rotation as a means to control to insect pests is most effective when the pests are present before the crop is planted have no wide range of host crops; attack only annual/biennial crops; and do not have the ability to fly from one field to another.
  • Reduces reliance on synthetic chemicals
  • Reduces the pests' build-up
  • Prevents diseases
  • Helps control weeds

Description of Product (s) or Process (es) and its Functionality (Succinct but Detailed Enough)

The method of crop rotation is somewhat self explanatory: the crop that is planted in a certain plot of land is rotated every 2-5 years. The crop preceding the current crop planted should be of a different family. The family names are listed in the table below. This is a method of pest control that has been very effective over time across many cultures. The method prevents host specific pests of harboring plants for long periods of time.

Table of Crop Groups

Common names
Chive, garlic, leek, onion, shallot
Cucurbit (Gourd family)
Bitter gourd, bottle gourd, chayote
cucumber, ivy gourd, luffa gourd, melons
pumpkins, snake gourd, squash, wax gourd
Crucifer (Brassica)
Bok choy (petchay), broccoli, Brussels sprouts,
cabbage, Chinese cabbage, cauliflower, collard,
kale, kohlrabi, mustard, radish,
turnip, watercress
Common beans, black bean, broad bean (Fava),
clover, cowpea, garbanzo, hyacinth bean,
kidney bean, Lima bean, lintel, mungbean,
peanut, pigeon pea, pinto bean, runner bean,
snap pea, snow pea, soybean,
string bean, white bean
Lettuce, artichoke
Solanaceous (Nightshade family)
Potato, tomato, pepper, eggplant
Grains and cereals
Corn, rice, sorghum, wheat, oat, barley, millet
Carrot family
Carrot, celery, dill, parsnip, parsley
Root crops
Cassava, sweet potato, taro, yam, water chestnut
Mallow family
Cotton, okra
Steps to this process, outlined by the above source, include:
  • Know the family where your crops belong to make sure that you plant on the next cropping a crop that belongs to a different family than the previous one.
  • Make a list of the crops you want to grow by also taken into consideration the market's demand of your produce. For example, plant leafy vegetable on the first cropping season, next fruit vegetables, then root crops, then legumes, then small grains
  • Grow legumes before grains or cereals
  • Practice green manuring
  • Always keep farm records

Design parameters

Parameters for this method simply include the type of crop that will proceed another crop.

Other resources Needed for Implementation/ Use


Execution of this method would mainly call for labor in replanting various crops.

Technical Skills Required to Operate or Utilize

Training Requirements

Training would have to be completed to ensure that the care takers of the land understood the steps outlined above.

Associated Costs

Cost of crop maintenance, which is defined elsewhere.

Operations & Maintenance

A large portion of the maintenance needed for this method of pest control will be in keeping good records of the crop life and plot history. There will have to be a standard process developed quickly.
