Soil conditioners, also called soil amendments, assist improve soil structure by increasing aeration, water holding capacity, and nutrients. They assist chop up compacted clay soils that lack enough space for air and water, which square measure vital for microorganisms to thrive and for plant roots to grow. They additionally cycle nutrients otherwise sure up within the soil. Soil conditioners embody a spread of merchandise made of many alternative materials, each organic and inorganic. Organic (carbon-based) soil conditioners like Bloom can be made of animal manure, fertilizer from yard waste or food waste, cover crop remnant, biosolids, sawdust, ground pine bark, peat moss, or other materials. Common ingredients in inorganic soil conditioners on the other hand square measure usually mineral-based mostly, like enlarged clay or sedimentary rock and even sand.
