BlueGold® Calcium-Phosphate [Soft Rock Phosphate] (OMRI Listed)


Certified Organic Calcium Phosphate (Soft Rock Phosphate)

BlueGold® Calcium Phosphate has a massive microbial profile. Soft Rock Phosphate should not be confused with Hard Rock Phosphate, which is treated with acids and caustic chemicals. Our BlueGold® Calcium-Phosphate is OMRI Listed. Phosphate input is especially important after Fall harvest or first thing in Spring, as it is the primary mineral plants look for as they begin their Vegetative cycle. Fall input is better as it can be massaged into the soil throughout the Winter.

BlueGold® Calcium-Phosphate also called Soft Rock Phosphate or Colloidal Phosphate. It is the soft clay-like material that lies between the various layers of Hard Rock Phosphate and is an excellent source of Phosphate and Calcium (Mega Cal-Sil, Cal-King, C4) for your plants. Soft Rock Phosphate should not be confused with Hard Rock Phosphate. Hard Rock is also known as Tri-Calcium Phosphate. It is often treated with Sulfuric Acid to produce Super Phosphate, reducing the Phosphate to a Water-Soluble form with caustic chemical additions to the detriment of structure and microbial colonies. Soft Rock Phosphate is washed off and accumulated in settling ponds during the mining process. The Phosphate source is completely natural and is, in fact, a genuinely remarkable fertilizer with a massive CFU/g microbial profile. Although both products contain Calcium and Phosphate, the nutrients in Soft Rock Phosphate are more readily available for your plants to use.

The King of Minerals™ in your soil is Phosphate. No mineral uptakes without available Phosphate. The Queen of Minerals™ in your soil is Calcium. Phosphate does not move or uptake without Calcium (Mega Cal-Sil, Cal-King, C4). Soft Rock Phosphate is a quick-acting source of Phosphorous already in Phosphate Calcium blend. Raw Phosphate minerals are tightly bound and require a slightly acidic soil (6.4 pH) and beneficial microbial activity to move properly in soil strata and uptake into plants. To achieve this more quickly rather than letting nature take its course, you can compost your raw minerals or use BlueGold® Super Phos-23, which is a mechanically micronized Soft Rock Phosphate combined with our BlueGold® Base Blend Wetting Agent for enhanced penetration.

Natural Phosphate stays in the soil where it is put and moves very little. All movement is achieved through microbial activity (a major deficient coast to coast in the United States) and through organic matter, the throttle for water (water is the carrier of many things). Unlike chemically processed Hard Rock Phosphate, Soft Rock Phosphate is insoluble in water. It will not leach away and therefore is long-lasting. However, because there is a microbial and organic matter problem in almost all farms, the use of a Wetting Agent (BlueGold® Base Blend) is instrumental in moving Phosphate in the soil by diffusion. The only alternative is too deep plow/till the soil, which only further injures microbial activity as anaerobic bacteria are flipped on top (into an aerobic environment), and the aerobic bacteria is flipped to the bottom (into an anaerobic environment).

BlueGold® Calcium-Phosphate is an additional big gun in the arsenal along with our BlueGold® Super Concentrates (Mega Cal-Sil, Cal-King, and Super Phos-23) and Raw/Injectable Aragonite (Calcium Carbonate) in the Nutrient War that rages in every field. You only have a short window in a Vegetative State to get the King of Minerals™ and Queen of Minerals™ sitting pretty on their sap PPM thrones. Our BlueGold® Calcium-Phosphate (Soft Rock Phosphate) is designed for all field and cross-dressing plants. It is very effective at low rates when used in conjunction with our super-concentrated BlueGold® Super Phos-23.

BlueGold® Calcium Phosphate should only be applied in accordance with an Apical sap/soil analysis. Results should dictate ongoing application rates. Ask us how to qualify for guarantees.
