Of these materials, urea (46% N) is generally the least expensive N source. Use of urea fertilizer gradually lowers soil pH.
Get MoreBoth ammonium sulfate and ammonium nitrate are nitrogen fertilizers and contain no phosphate or potassium. Please remember that these are also dangerous chemical compounds and should be handled with care and consideration for the people or pets around them, as well as nearby plants and trees.
Get MoreFertilizers containing calcium should be flushed from all tanks, pumps, filters, and tubing prior to injecting any phosphorus, urea-ammonium nitrate, or urea sulfuric fertilizer. Calcium should not be injected with any sulfate form of fertilizer because it combines to create insoluble calcium sulfate, or gypsum.
