How to reasonably determine nitrogen fertilizer application rates in precision quantitative rice cultivation
The quantification of nitrogen needs to consider the fertilizer requirements of high-yield rice, the pattern of soil nitrogen supply, fertilizer characteristics and the current-season utilization rate, as well as various changes during the growth period, and includes two parts: total nitrogen quantification and nitrogen fertilizer application methods. Determination of total nitrogen amount: obtained through soil testing and fertilizer recommendation trials
