Liquid Fertilizer


CSS produces liquid fertilizer solutions and blends to make your farming operation more productive and sustainable. All of our products are formulated with our flagship product, Harvest-to-Harvest™, as the base product of every formulation.

“H2H™ products are soil applied, and can be applied through any type of irrigation equipment”All Harvest-to-Harvest™ products are soil applied, and can be applied through any type of irrigation equipment, including: pivot systems, solid-set sprinklers, drip line, and low pressure drip tape. CSS recommends a minimum dilution rate of 4:1 with water when applying through high-pressure sprinkler systems. For drip line and drip tape, Harvest-to-Harvest™ should be water run and applied at .5 – 3% final line dilution directly into the main manifold. For smaller drip systems that are 300GPM and less, we recommend that Harvest-to-Harvest™ be diluted 4:1 minimum prior to injection. Please consult your CSS sales or technical sales rep to get more information on application and dilution rates.

Harvest-to-Harvest™ Liquid Fertilizer

Harvest-to-Harvest™ is a stabilized food hydrolysate that is derived from recycled supermarket organics. The term “food hydrolysate” simply indicates that it is the product of the digestion of food with enzymes into a liquid fertilizer. Harvest-to-Harvest™ contains complex forms of nutrients, including: carbohydrates, amino acids (proteins), organic acids, and fats. These complex sources of nutrition are a great source of nutrients and energy for soil organisms and plants.

Harvest-to-Harvest™ is also a great source of Organic Matter (20 – 25%), that can be applied through any existing irrigation equipment due to its small particle size (26 micron average ; 74 micron maximum). This small particle size along with its low C:N ratio make the organic matter readily consumable by soil organisms. This readily consumable organic matter contributes to nutrient mineralization, increased root mass, more efficient nutrient uptake, and provides greater water holding capacity in the soil with repeated applications.

Harvest-to-Harvest™ is 100% pathogen free and safe for use on all crops.
