What are organic soil amendments?
Organic soil amendments are materials added to soil to improve its physical properties, fertility, and nutrient content. Organic amendments come from living or once-living materials such as plants, animals, and minerals. These materials are added to the soil to improve its structure and enrich the soil with nutrients, making it a more hospitable environment for plant growth. Organic soil amendments also help maintain soil moisture levels, promote healthy microbial activity, and increase beneficial insects and worms' populations.
The benefits of organic soil amendments
The use of organic soil amendments has numerous benefits for both the soil and plants. Unlike synthetic fertilizers, organic amendments release nutrients slowly over time, providing a consistent source of nutrients for plants. Organic soil amendments do not burn plants' roots as synthetic fertilizers can, reducing the risk of over-fertilization. Organic soil amendments also improve soil structure, increasing its ability to hold onto nutrients and water. By improving soil's overall health, organisms such as earthworms and beneficial microbes are attracted to the soil, which can help control pests, improve plant health, and increase yields.
The most common types of organic soil amendments
There are several types of organic soil amendments available, each with specific benefits and uses:
- Compost: A mixture of decaying plant and animal matter that supplies nutrients and improves soil structure.
