What are the major types of fluid fertilizers, and what are the differences between them?
The major types of fluid fertilizers are suspension fertilizers and solution fertilizers. Solution fertilizers are dissolved completely in water. Suspension fertilizers are partially dissolved in water, but some of the nutrients, particularly potash, are suspended in the water in the same way mud is suspended in water. Suspension agents are used in suspension fertilizers (typically a clay material) to keep the fertilizer material from settling out. You may store true solution fertilizers as long as the temperature stays above freezing. You should apply suspension fertilizers on the same day the dealer blends them. What are some common grades of solution fertilizers, and of what are they composed? The two most common grades of solution fertilizer are urea-ammonium nitrate solutions (UAN). Basically urea and ammonium nitrate are dissolved in water. Because of the urea content, to avoid volatilization losses of nitrogen (N) to the atmosphere, you must follow the same constraints in managi
