Although boron deficiencies generally occur on sensitive soils, poor liming practices can induce deficiencies anywhere. “It’s important to identify these areas and break them down into their own management zones. Tweet us your questions at @WolfTraxInc, or comment on this blog. “Eliminating compaction makes it easier for water to flow to plants, carrying boron along with it,” Ferrie says. A substance may have its use restricted to certain articles or products and therefore not all the examples may apply to the specific substance. If you grow highly responsive crops, such as alfalfa, you’re more likely to discover a boron deficiency than if you grow low-responsive crops, such as corn. Boron is an element found naturally in leafy green vegetables like kale and spinach. The average yield was 225 bu/ac with Boron and 225 bu/ac without across locations, but there was a 50 percent increase in tissue B concentration from 8 ppm to 12 ppm when Boron was applied. How is this related to 3D printing you may ask? Nationality: Argentine: Occupation: Sociologist: Atilio Borón is an Argentine Marxist sociologist. For a legume-grass pasture on sandy soils, topdress 0.5 to 1.0 pounds of actual boron per acre annually. If a boron deficiency is indicated, apply 1 pound of boron per acre. In our December 2014 installment of Nutrient Navigator (“Plants Need Boron to Thrive”), we outlined how power-packed boron plays a critical role in yield. to 0.3 lb. “Some soils are naturally  alkaline, so you would anticipate boron problems there. Because boron enters plants through a process called mass flow (water moving into plant roots, carrying  nutrients along with it), crops grown in soils with low water-holding capacity and without irrigation might experience boron deficiency. Boron (5 B) naturally occurs as isotopes 10 B and 11 B, the latter of which makes up about 80% of natural boron. “In this situation, you must treat the plants, not the soil. But a sandy soil with the same water pH reading might need only 1,500 lb. Much boron is found in chemical compounds in its ore borax. If a farmer applied boron based on those tissue analyses, without considering the weather, he would have wasted his money.” If you’re not sure you have a boron uptake problem, run strip trials, in addition to soil and tissue tests and  visual inspections, he says.

Registration dossier . “For example, in Illinois, during the 2012 drought, early tissue tests showed boron was sufficient,” Ferrie says. The need to apply boron fertilizer to soybeans in southeast Nebraska is extremely low based on our current knowledge and limited acres of low organic matter sandy soils. Foliar boron applied at 0.3-0.5 lb/ac during early flowering stages resulted in yield increases 24 times out of 33 (73%), but there were also yield losses 21% of the time. But because of the minute amounts required—½ lb. Recommended application rates of boron are rather low (0.5 to 2 lb/acre), but should be carefully followed because the range between boron deficiency and toxicity in most plants is narrow. David Doll. It can also be found in coffee, grains, prunes, raisins, noncitrus fruits, and nuts. By coating each granule in the dry fertilizer blend, Wolf Trax Boron DDP® delivers a safe and even application of the micronutrient across the field.
