For example, by using the systematic approach and MYR, S has been found to be limiting rice yields in northeastern China, B is commonly found deficient where rapeseed is grown, higher plant populations have been tested in several provinces with success.

例如，通过使用系统方法和最高产量研究，在中国东北地区发现硫限制了水稻产量，在油菜种植区普遍缺硼，在好几个省份成功地进行了高密度试验。
