Novihum Soil Fertility Studies Show Higher Cotton Yields

Research and commercial trials for cotton performed by Novihum in Tennessee have shown yield increases ranging from 225 to 255 pounds per acre (lbs/A).

A three-year study at Agricenter International in Memphis tracked the effect of Novihum 25 – a novel humus concentrate to help improve soil fertility and health – at various band widths and application rates. The trial was conducted on a silt loam soil with a pH of 6.3 using Novihum rates ranging from 50-1,500 lbs/A at band widths of 6 and 12 inches. Two rates, looking at cotton yield alone, showed the highest results:

  • A yearly application of 150 lbs/A with a 6-inch band increased yield by an average of 225 lbs/A compared to the control.
  • A one-time large rate application of 1,500 lbs/A in a 6-inch band increased cotton lint yield by an average of 255 lbs/A.

An additional commercial trial in Tennessee showed that Novihum-treated areas at a 1,200/lbs/A rate showed an average cotton yield increase of 6.5%. The soil was slightly alkaline which naturally limits availability of iron, manganese, boron and copper. But soil sampling in the treated blocks showed increased amounts of those nutrients plus increased rates of nitrate, ammoniacal nitrogen, orthophosphate-P and total nitrogen immediately available to plants.

Additional trials of Novihum in cotton are scheduled for 2021.

Developed as a safe and reliable organic matter solution, Novihum is indistinguishable from the high-grade humus found in very productive natural soils. Over 20 years of research have shown immediate and long-term benefits such as improved water use efficiency and management, greater stress tolerance, better seedling growth and root development, measurably healthier soils and higher yields when applied to soils with various organic matter content.
