Product Details

The fineness of Agrowinn-Minerals has many advantages, including bringing nutrients to the soil root zone where they are needed. With dry or wet foliar application during the first three quarters of the growing period, you can correct many nutrient deficiencies.

If you substitute Agrowinn-Minerals (Rock Dust) for some of the chemical fertilizers you are currently using, you will have no increase in annual costs. Rather, you will have increased the value of your crops and the productivity of your soil.

Agrowinn Minerals:

  • is environmentally friendly and non-polluting
  • is not quickly soluble and has good residual
  • loosens compacted soil and enhances plant feeder root fertility
  • does not burn plants or seedlings

The finer Agrowinn-Minerals (Rock Dust) is ground, the less product is needed. Rock dust is of course, inorganic. And since microbes consume the fine dust easily, they then discharge organically available plant food. The warmer the climate, the more microbes that are available to create plant food.

Nutrition & Trace Minerals

From "Acres, U.S.A." by G.H. Earp-Thonw

Often it is the little things in life that really count. Who knows - the secret that keeps you from perfect health may be a tiny trace element no larger than the head of a pin - or even one-tenth the size of the head of a pin. Read this classic article from the 1950s - as timely today as when it first appeared - and you will understand just how important trace elements are. As Earp-Thomas relates, a mere six ounces of the trace mineral cobalt spread over 43,000-odd square feet of land became the difference between the fertility and barren-ness of a farm. Take six ounces of paint and try to spread it over 43,000 square feet surface, and you will comprehend how thin 6 ounces of cobalt must have been spread over 43,000 square feet of farmland- yet those six ounces to the acre saved the farm from ruin. Are you getting the trace elements? It will make little difference how much phosphorus, how much calcium, how much iron, how much this-or that ordinary mineral you are receiving each day if even one of the trace elements is missing from your diet.

Agrowinn-Minerals has Cobalt and an abundance macro and micro nutrients, and trace elements.

Agrowinn-Minerals (Rock Dust) and its Paramagnetic Powers

...25 grams of Agrowin rock dust was tested for the level of paramagnetic force which is characteristic of this type of rock dust. It was tested on a PCSM Soil Testing Meter developed by Dr. Phil Callahan who has been researching and writing about paramagnetism for many years. The sample tested was part of a 10 lb. order shipped to me from your company last week. The level of paramagnetism in this sample was measured at 1275 cgs. According to the ranges listed with the PCSM Soil Meter rock dusts which measure between 1200 and 2000 CGS are considered "good" rock dusts. The PCSM Soil Meter is manufactured by Pike Agri-labs.

Take care, Mark Grogan


Application
Dry Applications:

• A General Areal Coverage is 10 lbs per 1000 sq.ft. or 1 lb per 100 sq.ft. This works for Vegetables, Flowers, Lawns, before & after Sod installs, over Groundcovers and Shrubberies.
Any plant will benefit from mineralization, including Natives.

• Dust lightly without caking (apply like powdered sugar over the soil surface).

• Apply Every 2-3 months or min. 1-2 times per year or apply with each new crop planting.
(more depending on soil condition and plant type)

• Water after top dressing. (If you dust over flowering plants - water down the dust).


Any Potted Plants:

• Use 1-2 teaspoons per 1 gallon pot size.


Wet Soil Applications (in general):

• Suspend 1-2 tablespoons of Minerals in any Hose-end Sprayer, in 50 Gl Barrel use a minimum ¼ lb.
Syphoning devices and fertilizer Proportioners can be used as well as Gypsum-injectors.
With drip irrigation, agitate the Minerals and use clean water afterwards to clear the lines.
(Product passes 250 mesh, 40% of product is in the microns).


Aquaponic, Hydroponics, and Golf Course Applications:

Please inquire directly as each condition and system differs.


Any Tree:

• Broadcast around center canopy and beyond drip line as far out as possible.

• Use about ¼ to 1 pound per inch of Trunk diameter.
(1 lb can cover 100 sq.ft.)

• Dust lightly without caking (like powdered sugar over the soil surface).


All Trees In Orchards:

Apply the Minerals with your irrigation systems:
   Sample calculation for 100 lbs/acre/year,
       Irrigating Once per Month = 12 times
        (100 : 12 = 8.3 lb per acres)
        Irrigating Every 2 Weeks = 26 times
        (100 : 26 = 3.85 lb per acres)
Agitate to suspend the Minerals during injection and use clean water after to clear the lines.
1-8 pounds suspends easily in 100-400 Gallon of irrigation water.


Foliar:

• Sprayers: For 32 oz hand-spayers, use 1-2 Teaspoons.

• Hose-end-sprayer: 1-2 tablespoons, or as much as can be suspended in water.
Use every 1-2 weeks or as needed.
Works great for hard to reach hillsides and struggling plants, including trees to give them a boost.

• Spray over Vegetables to mineralize the leave greens.
