Benefits of HUM-TURF 1258 PKRF

American Humus

  • Increases the cation exchange and buffer capacity of soil and thus free P, Ca and microelements held by clay minerals and increase their availability to plants.
  • Chelates nutrients and reduces leaching of chemical fertilizers.
  • Increases organic matter in soil and decrease the use of inorganic chemicals fertilizers.
  • Helps break up compacted clay soils and allowing for enhanced water penetration and better root zone growth and development.
  • Adds essential organic material necessary for water retention in sandy soil and thus improving root growth and enhancing the sandy soil’s ability to retain and not leach out vital plant nutrients.
  • Mitigates the toxic effect on plants in high salinity and sodicity soils.
  • Enhances growth and proliferation of beneficial micro-organisms in soil.
  • Helps in balancing the soil pH.
