The portion of slow-release nitrogen is listed on the fertilizer bag as water-insoluble nitrogen (WIN). If no WIN is listed on the fertilizer label, assume that all of the nitrogen is water soluble or quickly available unless the nitrogen includes sulfur coated urea. Sulfur-coated urea fertilizers provide slow-release nitrogen, but the fertilizer label does not list it as WIN. If the ...

However, most crops use both ammoniacal and nitrate nitrogen. Proper nutrient management should include the "Four R's" of fertilizer use: apply the right nutrient, at the right rate, at the right time, and in the right place for the selected crop (Mikkelsen 2011). This article focuses on how to select the right fertilizer to enhance profitability and satisfy best management practices ...

When your fertilizer is sans urea, all of the nitrogen in your mix becomes available as food at once. In addition, soil-borne bacteria is needed to metabolize urea-based fertilizer to make it available as plant food for your orchid. This puts non-terrestrial orchids at a disadvantage. 6. Look for ammoniacal nitrogen or nitrate nitrogen in labels

pH Management and Plant Nutrition: Fertilizers

water-soluble fertilizers: ammoniacal nitrogen (NH4-N), nitrate nitrogen (NO3-N) and urea (Figure 1). Uptake of ammoniacal nitrogen causes the substrate-pH to decrease because H+ (acidic protons) are secreted from roots in order to balance the charges of ions inside the plant with the solution surrounding the outside of the roots. Urea is easily converted into ammoniacal nitrogen in the ...
