When it comes to fertility in crop production, nitrogen is one of the most critical nutrients involved. “Nitrogen plays an important part in many essential functions and compounds necessary for life,” says the University of Missouri Extension and can be found in various parts of plants.

Unfortunately, nitrogen fertilizer is…

For growers who are trying to follow the “4Rs” of nutrient stewardship — applying the right fertilizer source at the right rate, at the right time, and in the right place, as set forth by The Fertilizer Institute — variable-rate technology (VRT) can help them tackle two of the four…

It’s almost time to plant which means it’s time to make some varietal decisions…

It’s that time of year again where things seem to be waking up from the doldrums of Winter…the grass is greening up, pollen is falling everywhere and even an occasional snake shows up…not to mention snake-oil salesmen (kidding, kind of). …
