Correct application methods and precautions for slow-release nitrogen fertilizer
Traditional nitrogen fertilizer management for strong-gluten wheat is generally divided into two applications. The first is a portion of nitrogen fertilizer applied before wheat sowing in conjunction with plowing, accounting for 60%-70% of the total nitrogen application; the second is a topdressing applied from the spring green-up stage to the stem elongation stage of wheat in conjunction with watering, accounting for 30%-40% of the total fertilizer application. Some apply it before wheat overwintering...
