Nature has been re-mineralizing the soils of the earth through volcanic eruptions and sedimentation since the beginning of time. However, these valuable minerals have been significantly depleted in most soils over the years - and plant life, soil health and bio-diversity have suffered as a result. Today's soils contain no more than 16-20 minerals on average compared to 80-100 millions of years ago. Without these natural minerals, plants become weaker, require more water, produce less, contain lower nutrient levels and are more susceptible to stresses, pest infestation and other issues. Green Generations Andesite Mineral Complex is a volcanic-based rock dust containing essential and beneficial minerals and trace elements along with certified natural paramagnetic levels over 8,000 cgs to help condition and balance the equilibrium in the soil while stimulating microbiology to create an nutrient-dense environment in which plants can thrive. Andesite Mineral Complex is 100% natural, biodynamic and safe for use on all indoor and outdoor fruits, vegetables, flowers, trees, shrubs and lawns, will not burn or harm plants and cannot be over-applied. Andesite Mineral Complex can also be used in aquaponics & hydroponics systems and on green roofs, living walls, equestrian, cattle, dairy and other grass-fed animal pastures, orchards, vineyards and more. Andesite Mineral Complex meets National Organic Program (NOP) standards for certified organic production. Andesite Mineral Complex has an approximate mesh size between 80-100 on average and comes bulk-packaged in a heavy-duty 3mil plastic bag.
