We introduce several methods for applying ammonia to main crops

    Different types of crops require different fertilizer characteristics. In order to fully utilize the effects of ammonia, fertilizers should be applied according to the crop's fertilizer requirements.

Winter wheat:

    In order to obtain a bumper yield for wheat production, in addition to deeper ploughing and soil improvement, selection of improved varieties, and strengthening of field management, comprehensive utilization of fertilizers, especially nitrogen chemical fertilizers, has a great influence on wheat production. According to the analysis of Shandong Academy of Agricultural Sciences, when the yield is 609.6 kg, the wheat absorbs 16.84 pounds of nitrogen from the soil and absorbs 2.8 pounds of nitrogen per kilogram of seed. Experiences from high yields in various regions have proven that applying nitrogen fertilizer and using phosphorus and potassium fertilizers are among the key measures to achieve high wheat yield.

    Based on the application of farmyard fertilizers, qualified units can use a certain amount of ammonia as base fertilizer. Generally 30,50 pounds per acre, using the fertilization method with the plough in the arable land, can also be used to introduce ammonia water fertilization machine or ammonia urn and other furrows. The depth of fertilization should be less than 10 cm, with the use of fertilization with soil, to prevent the volatilization of ammonia.

    Ammonia topdressing should be applied before winter, green, and jointing, and ammonia water should be applied according to the growth of wheat seedlings. Generally, each topdressing ammonia water 30, 40 kg, forced method, can be ditching or flushing with water; in the South there are splashing habits of the unit, you can also use splash method, but should pay attention to water multiples, and Fertilize at low temperatures.
