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.

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%.
Plot A) GENESIS with Sumagrow test plot 7.55 acres
Applied ½ gal.SumaGrow per acre along with reflex after planting
Applied ½ gal. SumaGrow per acre 5 weeks later over top spray (1.0 gallon total per acre)
Applied 20 gal. nitrogen per acre at layby and 15 gal.nitrogen per acre after planting (total 35gal)
Applied 2 tons chicken litter and 150 lbs per acre of potash (preplant) per acre.

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
Total Dollar GAINS from Genesis with SumaGrow per acre $334.68
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.
HIGHER YIELD
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%.
HIGHER QUALITY
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%.
RESULTS
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!
