China Cotton Study at Jiangxi Agricultural University Shows 28.3% Yield Increase

This university study doesn’t have many specifics, however, we do know the lint (what the farmer actually gets paid on) yield increase went up 28.3%.  Three gallons of SumaGrow were used per acre due to poor soil health.

Arkansas Cotton Farmer Obtains Additional 100 Pounds of Lint per Acre

These amazing results were sent in from Danny Quall’s farm in Jonesboro, Arkansas. Danny grows 1500 acres of cotton in addition to other crops that he treats with a conventional fertilizer program.  Danny chose two 10 acre conventionally fertilized plots of cotton, one of which he treated with a product containing SumaGrow. The 10 acres treated with a product containing SumaGrow:
  • Produced 100 lbs/acre more in lint cotton
  • Produced $10/acre more in cotton seed
  • Matured 10 days earlier
  • Tap root was an average of 6” longer
After the cotton reach maturity, it was exposed to a wind storm that produced winds in excess of 50 mph. The plot treated with SumaGrow stood tall and was undamaged.  The untreated cotton was pushed to the ground, inflicting damage to the stalk and cotton bolls.

Georgia Cotton — Sayer Farms Increases Lint Yield by 27.7%

This trial was conducted on Sayer Farms, in Irwin County, Georgia on two dry land test plots after 2.5 weeks with no rain.  The soil type was the same for both plots which are across a dirt road from each other.

The SumaGrow treated plot showed a 27.7% increase in lint yield and a 27.6% increase in seed production.  Nitrogen fertilizer was also reduced by 58.8%.

Net Production and Profit Comparison

Lint: Genesis with SumaGrow gain

1318 lbs – 1032 lbs = 286 lbs per acre x .84 per lb.(1/02/14)                        =$240.24

Seed: Genesis with SumaGrow gain 

1515 lbs – 1187 lbs =328 lbs per acre x 10.5 cents                                      =    34.44

Nitrogen: Reduction with Genesis with SumaGrow                             =    60.00

Cotton in Tarboro, North Carolina: Yield Increase and Quality Increase

These results show the yield and quality increase on a 138 acre cotton farm in Tarboro, NC.  The cotton farmer also raises chickens so approximately 13 tons of chicken litter was applied.  A product containing SumaGrow was used on 65 acres with no additional fertilizer while the remaining 73 acres was treated with chicken liter, as well as 40 units of nitrogen and 25 units of sulfur fertilizer per acre.


The treated acreage averaged 1079.49 pounds per acres while the control acreage averaged only 915.58 pounds per acre, an increase of 16.92%.


The Bale Analysis Report (link below) shows the quality of the cotton was substantially better than the control.  Higher grade, higher strength and a lower percentage of trash in the treated acreage cotton led to a price of 92 cents per pound for the farmer versus only 52 cents per pound on the control acreage, an increase of 77%.


Combing the higher yield with the higher quality price received, the farmer increased his revenues by 106% per acre ($989.55 vs. $480.20).  Actual bottom line profits would be an even greater percentage increase as all other expenses stayed the same, with the exception of the fertilizer expense, which was actually lower on the treated acres since no commercial fertilizer was used.

The farmer had previously told our distributor he would use SumaGrow next year on all of his soybeans, however, after seeing the results on his cotton; the farmer has now decided to not plant any soybeans, just cotton!
