  Sonoma Compost products are used by local farmers to grow just about every crop of interest in Sonoma and surrounding counties. Currently, a wide range of vegetables, apples, berries, olives, grapes and flowers are grown with the help of our premium quality compost and mulches.

According to our farmer customers, they use Sonoma Compost to increase the percentage of organic matter in their soil, build soil structure and improve tilth, add nutrients and make nutrients in the soil more available to their plants. They also use it to conserve moisture and improve general soil health by introducing a diverse population of beneficial microorganisms.
