Soil conditioners are substances added to soil to improve its physical properties and fertility. They are used to enhance soil structure, water retention, aeration, nutrient availability, and overall soil health. Soil amendments can be organic or inorganic materials that interact with soil particles to create a better environment for plant growth. These materials can be incorporated into the soil before planting or used as a top dressing for existing plants. Soil amendments are essential for maintaining soil health and productivity, especially in agriculture and gardening.
