Nitrogen can be applied in an organic or inorganic form. Determining the amount of nitrogen in a fertilizer and how much of the fertilizer product to apply is easy. The application of nutrients other than nitrogen should be based on a soil test. Soil should contain an adequate supply (40 ppm) of nitrogen (N) when the garden is planted.
amount of nitrogen fertilizer. Nitrogen in water applied late in the growing season, after the crop has already taken up most of its nitrogen needs, is of limited value. Care must be taken to reduce drainage below the root zone since nitrogen will leach with the water. The sections on irrigation scheduling are critical to reduce these losses.
This means the majority of your commodity nitrogen fertilizer leaches into the soil and water, where it cannot be used by plants and instead damages the environment. Our liquid nitrogen fertilizer can be used in smaller amounts, while creating the same or, in many cases, better results.
