A solid trial resulting in a 14.3% yield increase while reducing the grower standard amount of fertilizer by 50%. The trial report also notes a huge increase in the soil organic matter which is the true test of soil health.

This study started in February of 2013 on approximately 30 acres in Hancock County, Mississippi. ArborGen improved second generation Loblolly Pine (Pinus taeda) seedlings were planted at the rate of 550 seedlings per acre. The seedlings were treated with a solution of water and varying amounts (2 oz. to 14 oz.) of SumaGrow by briefly placing the seedling roots in the solution, a “root dip.”
The treated seedlings are growing approximately one extra foot per year versus the control.

Arise Research is one of the few facilities which can accurately measure nitrate runoff. Each plot is grown in a containment bay where there is a plastic lining on the bottom and sides. There is also a piping system in the containment bay to collect the runoff which goes into a holding tank (58 in the photo below). The water is collected from the holding tank where it can analyzed.
An interesting tidbit was reported in an email that there had been deer damage to the SumaGrown test plots where the deer were observed eating the SumaGrown plots and not the others. This has been reported anecdotally several times; the animals instinctively know which crops are better (SumaGrown), likely due to the higher brix levels — better taste (higher in natural sugars) and higher nutritional value.
