Pure flowers is marketed in a way that would make one think its better than phosphate as a form of phosphorous.

On the other hand,Phosphonates were first investigated as fertilizers in Germany and the U.S. during the
1930s and 40s. At that time, agricultural officials were concerned that war activities
would disrupt vital shipments of rock phosphate for fertilizer production, so alternative
sources of fertilizer phosphorus were explored (6). Results of studies conducted in both
countries demonstrated that phosponates were not effective substitutes for phosphate
fertilizer. USDA scientists found that yields of legumes and grasses treated with calcium
phosphite were lower than phosphate-treated plants, and in most cases, lower than
controls plants receiving no phosphorus. However, a second crop seeded into the same
soils that were treated with calcium phosphite showed improved yields. The authors
attributed the delayed phosphorus response to the conversion of phosphite to
phosphate in the soil (9). Subsequent research revealed that phosphite could be
converted to phosphate primarily by soil-borne bacteria, but that these bacteria would
not use phosphite until most phosphate was depleted (1). Based on the results of these
studies, phosphonate fertilizer was viewed as an inefficient and costly means of
supplying phosphorus to plants and scientists eventually lost interest in this compound
as a phosphorus fertilizer.
Despite previous research findings, phosphonate compounds are marketed by some
companies as a source of phosphorus and potassium fertilizer.
Pure flowers is marketed in a way that would make one think its better than phosphate as a form of phosphorous.
Pure Flowers 0-30-20 liquid was scientifically formulated with cutting edge phosphite technology. Pure Flowers 0-30-20 has the highest nutrient levels ever achieved in a completely solubilized liquid. The unique molecular structure of a phosphite is easily absorbed through the roots and leaves ensuring the crop instantly uptakes potassium and phosphorus. The ultimate flowering supplement will maximize your crops yield and boost the crops immune system.
