40-0-0 (Urea sulfate) is a nitrogen fertilizer. It is a rich source of nitrogen, able to meet the needs of plants throughout the biological cycle. 40-0-0 is applied superficially to the widest range of crops.

Limus® is a urease inhibitor developed and patented by BASF. Limus® combines two active ingredients, which complement each other, synergistically enhance and are more effective on the range of soil urease enzymes than a single inhibitor. Greater urea protection leads to improved nitrogen availability during critical crop growth stages for more consistent yields.
