    土壤养分是指土壤提供给作物生长的必须营养元素,包括氮(N),磷(P),钾(K)等13种元素。土壤养分含量的多少,可通过土壤养分速测仪测出。然后对照土壤养分丰缺指标,就可判断这块土地的养分含量多寡。因为在我们对一块土地进行调查研究或者播种施肥前,都需要对这块土地的土壤养分含量进行一定得了解。只有这样,才能更好地利用土壤自身含有的养分,同时及时补充含量不足的元素。

近红外土壤养分速测仪应用光谱技术,结合数据挖掘和融合技术,对土壤中的各养分进行了测量。同时由于运用近红外技术,使得它区别于一般的土壤养分速测仪。近红外土壤养分速测仪最显著的特征是:不破坏样品,不需要化学试剂、检测时间少于1分钟。
