A 2018 UW research study compared TerraNu Calcium to other calcium sources for potato nutrition. The study was conducted on chip potatoes, Atlantic variety, by Dr. Matt Ruark and his team at the University of Wisconsin-Hancock Agricultural Research Station. Potato quality assessments were conducted by UW and Techmark, Inc.
Study conclusions:
- TerraNu Calcium improved gravity and reduced the amounts of sucrose and glucose, when compared to gypsum, pelletized gypsum and control.
- Applying TerraNu Calcium reduced total defects (internal and external) between 2-21% when compared to other treatments.
2018 On-Farm Potato Trials in Wisconsin, Michigan and Minnesota Showed:
- Increased potato yields between 20-80 CWT/ac. with the addition of TerraNu Calcium as the calcium source vs conventional programs with other sources of calcium.
- Potato sizing improved between 3-10% with TerraNu Calcium, reducing the number of undesirable sized potatoes and increasing marketable yield.
- Field crop, tuber uniformity, individual size and total tuber counts also increased as a result of adding TerraNu Calcium.
