Companion planting can help improve nutrient absorption in plants by promoting the growth of companion plants that have deep roots or are nitrogen-fixing. Deep-rooted plants can bring up nutrients from deeper layers of soil and make them available to other plants. Nitrogen-fixing plants, such as legumes, have the ability to convert nitrogen gas from the air into a form that plants can use, which can help increase nitrogen levels in the soil.
Some examples of companion plants that can improve nutrient absorption include:
- Beans or peas, which are nitrogen-fixing and can help improve soil fertility.
- Carrots or parsnips, which have deep roots and can break up compacted soil, making it easier for nutrients to move through the soil.
- Garlic or onions, which can repel pests and diseases and help improve soil fertility.
- Radishes, which have taproots that can break up soil and increase nutrient absorption.
- Herbs such as comfrey or chamomile, which can improve soil fertility and attract beneficial insects.
By planting these companion plants alongside your main crop, you can help improve the overall health and nutrient levels in your garden.
