Agrowinn-Minerals is the finest rock dust on the market (also known as rock powder or stonemeal). Rock dust is environmentally friendly and will not leach into your ground water. It is also a slow release product; its super-fine particles will pass through a 2500 mesh screen with water agitation. It is also easily applied with boom-type sprayers with diaphragm pumps only.
Agrowinn-Mineral's fine-ness has other advantages as well, in that it brings the 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. Agrowinn-Minerals have an extraordinarily high level of minerals and trace elements (57 different trace elements) in well balanced quantities. (Contact us for a complete trace element list).
