Understanding nitrogen requirements for plants helps gardeners supplement crop needs more effectively. In Minnesota, good crop production usually requires an application of more than 20 pounds of nitrogen per acre. The key to most efficiently using urea is to incorporate it into the soil during a tillage operation. For Established Roses: Use a high-nitrogen fertilizer or top dress with alfalfa meal (5-1-2) for the first application to jump-start leaf development, along with epsom salts to encourage new cane development and lusher growth. Some nitrogen fertilizers tend to reduce the pH of the soil and thatch slightly. Table shows corn yields after applying 80 pounds of N per acre in Lamberton. Always check the nitrogen analysis on chemical fertilizer packaging to determine the percentage amount of nitrogen present. Studies that continuously use urea have been conducted in Lamberton since 1960. Nutrients, such as nitrogen and phosphorus, are essential for plant and animal growth and nourishment, but the overabundance of certain nutrients in water can cause a number of adverse health and ecological effects.Nitrogen, in the forms of nitrate, nitrite, or ammonium, is a nutrient needed for plant growth.

The Haber process, also called the Haber–Bosch process, is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today. Slightly higher in phosphorous to promote flowering (and subsequent fruiting), it also is a good source of nitrogen. When soil pH is too high or too low, grasses can't access nitrogen or other nutrients effectively. However, when urea was side-placed as a 2-by-2-inch starter, researchers noted little, if any, damage (Table 7).
