Fluid Journal : Fall 2017
19 The Fluid Journal Fall 2017 Table 2. NuCal liquid lime flow is controlled through orifices seated directly at the manifold connection. Product flow of liquid lime suspension is assured by eliminating air space and water flushing after every use and refill to prevent plugging and drying.

This was achieved at significantly reduced application rates in wheat production compared to standard liming practices. In fact, through extensive field testing of micronized fluid lime, when properly and strategically applied to inland Northwest wheat soils, has proven to be a very economical and effective method of long term pH management. The result is a positive and annual return on investment. The best part is that the application process is easy, efficient and virtually waste free. In fact, all of the lime that you pay for goes exactly where you want it: into the soil that will feed plants and maximize your crop yield now, not in the unknown future. The ability to integrate precision application methods using NuCal micronized fluid lime in the described manner allows a level of control most of us never thought possible. We challenge wheat growers to take steps now that will enhance pH immediately and increase profits by using NuCal. Summing up The final results of the test suggest that a precise application rate of micronized calcium carbonate lime into the low pH soil strata can also positively affect yield. A positive ROI was possible, even in an otherwise very soft wheat market. At a club wheat price of $5 per bushel x a 6.8 bushel crop increase per acre and a treatment cost of $25 per acre, the return on investment was 36 percent. Figure 7.
