A soil amendment is a material added to soil to improve its physical or chemical properties. Common types of soil amendments include organic matter, such as compost and manure, and inorganic materials like lime and gypsum. These amendments can enhance soil structure, increase nutrient availability, and improve water retention, making it easier for plants to grow. Using soil amendments can lead to healthier plants and better crop yields. They can also help correct soil imbalances, such as acidity or nutrient deficiencies. Regularly amending soil is a key practice in sustainable agriculture and gardening, promoting long-term soil health and productivity.
