Crop rotation is a technique that regularly varies the type of crop grown in a certain area in order to increase the soil’s health. It also helps to control weeds, insects and diseases.
Some crops use up the nitrates in the soil and others, like beans and peas, restore them. By changing what crop grows in a field each year the natural cycles can be used to improve growth and take away the need for artificial fertilizers and chemical based growth promoters. Crop rotation improves the environment by returning most organic waste to the soil, increasing humus levels and allowing nature’s cycles to work.
While crop rotation may sound outdated, it is a far better solution than chemicals. Unlike crop rotation, chemicals only provide the crops with three basic elements, without supplying them with all the necessary nutrients.
Ecologists think that these methods should be widely used and many people are already changing because they know that ‘organic’ foods have been produced without harming the environment.
Advantages of Crop Rotation
- Crop rotation improves and maintains soil fertility
- Crop rotation ensures that a sufficient amount of nutrients are accessible to the crops
- Crop rotation helps control weeds, diseases and pests
- Crop rotation helps soil to maintain its structure and organic matter levels
By using these techniques organic farmers not only improve the quality of their crops, but also help in reducing the pollution in our environment and greenhouse gases.
