PURE BLEND PRO ™ Soil Formula
Hydro-organic Fruit and Flower Soil Formula
American Agritech has specially formulated this organic bloom nutrient
formula for plants cultivated in soil and for the final ripening of fruit in the
last stage of hydro-organic gardening.
Cultivating fruiting and flowering plants in hydroponics requires less
phosphorous levels than potassium and even nitrogen. In hydroponics, phosphorous
levels that are too high tend to lock out calcium, magnesium and trace minerals.
On the other hand, plants grown in soil need higher phosphorous levels due to
clay colloidal particles that bind up phosphorous. Microbes in the soil also
compete for the phosphorous.When cultivating fruiting and flowering plants in
soil, growers usually need to double or triple phosphorous levels, unlike
hydroponics, thus making the 1.5-4-5 formula ideal for soil applications.
