How It Works Nitrogen MaximizersInstinct® and NServe® nitrogen maximizers deliver maximum profit by extending nitrogen availability during corn's key growth stages. They work underground, where up to 70 percent of nitrogen loss can occur through leaching into the ground or denitrification into the atmosphere.
ore have to be oxidised before leaching leaching the cured ore at a pressure of between about atmospheric pressure and about 5 atmospheres, at a temperature between about 5° C. and about 65° C., through the application of a leaching solution thereby producing a pregnant leach solution in which at least 20% of the cobalt initially present in the oxidised cobalt ore is dissolved.
