更为普遍的是，土壤肥力低下，耕作管理粗放，严重制约了有限降水的资源化。

More generally , the low soil nourishment and the increasing use of land to expand production on farming management strongly restrict the utilization of limited precipitation resource .

然而，只要是管理得当，在水源充足、或者是土壤湿润度及土壤肥力管理均能跟上的情况下，就有可能带来可观的收益。

But with good agricultural husbandry , it is possible to realise positive returns when the availability of water or moisture is integrated with soil fertility management .
