Companion planting

Definition

Companion planting is an agricultural practice that involves growing different plants together in close proximity to enhance growth, repel pests, and improve the overall health of crops. This method is based on the idea that certain plants can benefit each other when grown together, leading to increased yield and reduced need for chemical pesticides. It plays a significant role in sustainable agriculture and food systems.

5 Must Know Facts For Your Next Test

1. Companion planting can help deter pests by using plants that repel insects or attract beneficial predators, reducing the need for chemical insecticides.
2. Some combinations, like planting tomatoes with basil, can enhance flavor and promote healthier growth due to their complementary nutrient needs.
3. This practice supports biodiversity by creating a more varied ecosystem, which can lead to improved pollination and healthier soil.
4. Certain companion plants can improve soil fertility by fixing nitrogen or adding organic matter when they decompose, benefiting neighboring crops.
5. Companion planting is a key strategy in organic farming, aligning with practices aimed at promoting ecological balance and sustainability.

Review Questions

• How does companion planting contribute to pest management in sustainable agriculture?
  • Companion planting plays a crucial role in sustainable agriculture by naturally deterring pests and reducing the reliance on chemical pesticides. For example, certain plants emit scents that repel harmful insects or attract beneficial predators like ladybugs. This natural form of pest control not only protects crops but also maintains ecological balance and promotes healthier farming practices.
• Discuss the benefits of companion planting for soil health and crop yield.
  • Companion planting benefits soil health by promoting biodiversity and enhancing nutrient cycling. Some plants, like legumes, can fix nitrogen in the soil, while others add organic matter as they decompose. These interactions create a more fertile environment that supports higher crop yields. When plants work together in this way, they can also help each other resist diseases and withstand environmental stresses.
• Evaluate the role of companion planting within the larger framework of sustainable food systems and its impact on modern agriculture.
  • Companion planting is integral to sustainable food systems as it emphasizes ecological practices that reduce reliance on synthetic inputs while enhancing biodiversity. This approach not only improves crop resilience and yield but also fosters healthier ecosystems. By integrating companion planting into modern agricultural practices, farmers can contribute to more sustainable production methods that address challenges such as climate change, soil degradation, and food security while promoting an interconnected approach to farming.
