When growing crops, keeping pests and disease away are key to success. A common solution is to use pesticides.
But what exactly are pesticides and how do they affect the planet?
Large industrial farms use pesticides and other harmful chemicals to protect crops and animals from pests and disease.
In some cases, the chemicals enter local water sources and can negatively affect other animals nearby. These farms grow large quantities of crops and so pesticides help them save time and energy.
Local farmers with smaller farms tend to avoid using pesticides and other chemicals. Instead, they use natural pest and disease control methods. 3 key examples are crop rotation, intercropping, and companion planting.
1. Crop Rotation
Crop rotation prioritizes soil health by optimizing nutrients while fending off pests and weeds.
By planting different crops on the same plot of land, farmers allow their plants to return nutrients to the soil naturally.
Different plants have different nutritional needs. So if a farmer plants the same crop in the same land every year, they continuously draw from the same soil.
2. Intercropping
Similar to crop rotation, intercropping refers to growing two or more crops at once on the same land.
It’s a common practice for farmers looking to reduce weeds as intercropping naturally inhibits weed growth.
The chosen crops must meet height, rooting ability, and nutrient requirements to ensure success.
By intercropping, farmers yield more crops while reducing weeds.
3. Companion Planting
This is the practice of growing plants together for mutual benefit.
By companion planting, you’ll attract insects and pollinators while fending off predators and wildlife.
Planting crops close together helps improve nutrient supply in the soil.
When done strategically, companion planting also allows certain fruits and vegetables to grow stronger. Taller crops provide shade for smaller/shorter crops, helping them better withstand the scorching summer sun.
Conclusion
By using these 3 farming methods for natural pest and disease control, local farmers can produce healthier crops for the community to consume.
This is also beneficial for the environment.
