   Applying 10-10-10 for non-bearing trees remains the standing UGA recommended program for non-bearing trees. There are other products on the market that may provide additional benefit to young trees. Terra-Sorb is a superabsorbent, hydrogel material that claims to increase water-holding capacity of the soil 150 times its weight in water. It has never been researched in Georgia pecans. A trial was conducted in Pierce County, Georgia on first-year planted Excel pecan trees to observe the difference between Terra-Sorb and the UGA Fertilizer program. The four treatments compared were: Terra-Sorb, UGA Fertilizer Program, Terra-Sorb + UGA Fertilizer Program and a control. These trees were planted in December 2019 with 1 pound of Terra-Sorb applied per tree. Tree height and caliper measurements were compared at the end of the season, along with leaf tissue analysis. In the first year, no statistical differences were found in height and caliper measurements, as well as nitrogen, phosphorous, and potassium content in the leaf.
