Field Applied Nitrogen Fertilizer Brochure

Nitrogen is essential for healthy plant growth and good yield. Straight nitrogen fertilizers are often the major source of this important nutrient.Nitrate forms of nitrogen are most swiftly absorbed by crops, which is why they are commonly used when a fast response is needed. In contrast, ammonium- and urea-based fertilizers need to be transformed by microbe activity in the soil before plants can absorb them. Therefore they are more commonly used where a more gradual uptake of nutrients is needed.
