Titan XC Improves Potato Yields in Idaho Trials

Posted by Agricen

In a split-farm trial harvested in 2020, the grower's potato yield was increased by +105.1 sacks per acre where his dry fertilizer had been treated with Titan XC to maximize prill breakdown and nutrient release, as compared to yield where untreated dry fertilizer had been spread. There were also fewer culls (unmarketable potatoes) where Titan XC had been used.

These potato yield results followed the team's findings from the 2019 season, where a split-field trial showed that potatoes grown with Titan XC-treated dry fertilizer outyielded the untreated dry fertilizer by +19 sacks per acre (572 cwt/acre with Titan XC vs 553 cwt/acre untreated).

Josh and his team also noted that they performed weekly tissue testing throughout the 2020 growing season and observed that potato plants grown with Titan XC-treated dry fertilizer showed a trend toward higher tissue phosphate levels compared to the untreated dry fertilizer. 

In Idaho, high lime, high pH soils mean that soil phosphate deficiencies are not uncommon. This is because applied phosphorus will react with calcium in the soil, which makes the phosphorus insoluble and unavailable. By applying Titan XC on dry fertilizer, growers can address this limitation and enhance the availability and uptake of phosphate and other nutrients from dry fertilizer. Titan XC accelerates the breakdown of treated dry fertilizer and helps facilitate mineralization – the conversion of organic nutrients into inorganic, plant soluble, plant available forms. With more nutrients available, more nutrients can be captured by the plant, which can lead to significant yield benefits.
