Benefits of HUM-CORN 1258 PKRN

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.

K deficiency SymptomsPhosphorous deficiency Symptoms
Chlorosis (Yellowing) and necrosis (tissue death) of the maize leaf margins, beginning on the lower leavesReduced early plant growth and tiller development.
Older leaves turn yellow with tissue necrosis along the margins, but the upper new leaves may remain greenYoung corn plants often turn purple.
Stalks lodging ( breakage of the stalk below the ear)Plants remain green but older leaves have reddish-purplish leaf tips and margins.
Plants are smaller and grow more slowly than do plants with adequate phosphorus.
