Uncertain rainfall hinders soil health investment in much of sub-Saharan Africa
Nature Food ( IF 23.2 ) Pub Date : 2022-04-25 , DOI: 10.1038/s43016-022-00494-y


A farmer’s decision whether to use fertilizer is complicated in rainfed areas because the resulting yield gains vary greatly depending on rainfall, temperatures, soil conditions and many other factors. Farmers on about 25% of sub-Saharan Africa’s rainfed maize-growing land face an unacceptably high likelihood that this productivity-enhancing input will not pay off.

不确定的降雨阻碍了撒哈拉以南非洲大部分地区的土壤健康投资

在雨养地区,农民是否使用化肥的决定很复杂,因为由此产生的产量收益因降雨、温度、土壤条件和许多其他因素而有很大差异。撒哈拉以南非洲约 25% 的雨育玉米种植土地上的农民面临着这种提高生产力的投入无法产生回报的可能性高得令人无法接受。
