DOS GREEN WASTE COMPOST & ORCHARD COMPOST
Thermophilic compost produced from green waste created right here in the Coachella Valley. Primary derivatives are landscape clippings, grass clippings and tree trimmings. The green waste is arranged in large windrows, watered and turned on a regular basis to heat it to 160*F. This process kills weed seeds and pathogens. Compost is an excellent and easy source of organic matter for soil. The Green Waste Compost is a 3/8” screen; the Orchard Compost is not screened; it will have 1-2” pieces mixed through.
CV DESERT COMPOST & ORCHARD COMPOST
Much the same as DOS Green Waste Compost and Orchard Compost, but is CDFA registered and is OMRI listed.
VERMICOMPOST
100% Earthworm casting compost. Non certified castings are derived from earthworms consuming large windrows of dairy manure and/or green waste compost. Certified are derived from earthworms consuming certified green waste compost.
VERMIGROW COMPOST
Vermigrow compost is a 50/50 blend of certified organic worm castings and certified organic green waste compost. It is then bagged in 1 cubic foot bags, 50 bags to a pallet. CDFA Registered and OMRI listed.
CANNING MIX
Canning Mix is derived from stable shavings from HITS horse show. Windrows of the shavings are somewhat composted and screened at 3/8”. They are then mixed with unscreened shavings and sand. Gypsum, earthworm castings and perlite are also available to add to the mix for further enhancement.
MINED GYPSUM
Mined from the gypsum mine in beautiful Blythe, Ca, it is CDFA registered and OMRI listed. Gypsum provides sulfur and calcium for a healthier soil for your crops. Calcium improves soil structure, aeration and drainage, resulting in increased water infiltration and reduced soil surface crusting and improved seedling emergence. Gypsum also helps break up compacted soil critical for increasing rooting depth, stabilizes organic matter and decreases nitrogen loss to the atmosphere. Gypsum also displaces sodium on soil particles thus flushing it from the soil.
SOIL SULFUR
Soil Sulfur is a sulfur pastille that can be blended with other fertilizers or can be applied by itself. The sulfur is used to treat sodic soils and to reduce the soil pH. The sulfur is oxidized and combines with water to form sulfuric acid. The sulfuric acid reacts with the lime in the soil to form Gypsum or Calcium Sulfate. The Gypsum reacts with the sodium in the soil to forms a calcium-based soil which promotes better water penetration and aeration. Sodium sulfate is formed during this reaction and can be leached out through the soil profile. As a general rule, one-acre foot of water passed through the soil will leach out 90% of the salts.
