Reducing the use of heavy metals and herbicides

Best practices in reducing the use of heavy metals and herbicides

  • In newer planting areas, reduce the level of metallic copper by using lower dose coppers.
  • In well established fruit and tree crops increase the use of biological controls as part of overall fungicide and insecticide programs to promote growth of microbial populations.
  • Reduce the use of herbicides as much as possible, specifically glyphosates due to chelating properties that reduce micro nutrient levels in soil.
  • To the extent possible, use naturally mined materials in fertilization such as rock phosphate to increase mycorrhizal populations, gypsum to promote breakdown and uptake of calcium and sulfur, calcium carbonate to promote uptake of calcium and production of carbonic acid.
