Soil amendments and additives are applied to soil to improve its abilities, including water retention and absorption. The goal of soil amendments is to provide a healthier environment for roots to grow. Often times, they are mixed at precise ratios in tank loads with hydromulch depending on site conditions.
Soil amendments and additives come in many forms to serve the same ultimate purpose: optimizing germination. Some of the benefits include reducing compaction and helping with the in-soak of precipitation, balancing the mineral content and acidity of the soil, and increasing the organic content of the soil.
