Keith Day Ag Services has been serving the Salinas Valley since 1986 and is now the largest producer of organic compost and soil inputs on the Central Coast. We provide custom compost and soil amendment blends, as well as lime, gypsum, trucking, and spreading services. Our experienced team works closely with farmers, vineyards, contractors, landscapers, and nurseries to create tailored solutions that deliver consistent quality and value.

Our Investment in Quality

We operate multiple compost and soil blending facilities throughout the Central Coast, equipped with state-of-the-art grinders, compost turners, and screening systems to ensure consistent product quality. Our process starts with careful monitoring and inspection of incoming feedstocks that include landscape trimmings, agricultural culls, spent mushroom substrate, and grape pomace. Every batch undergoes rigorous testing before it leaves our site, ensuring our commitment to delivering a high-quality, uniform product.

Custom Soil Blends

Keith Day Ag Services produces high-quality soil blends tailored for row crops, vineyards, orchards, landscapers, greenhouse production, and a variety of horticultural applications. Blends may include compost, lime, gypsum, and other materials customized to meet specific soil and crop needs. Combining materials into a single, consistent blend helps improve application efficiency and reduces overall soil compaction.
