“农民只需开通常规的手机服务，植物需要水时就会（给他/她的手机）发送一条短信。”
For areas that receive regular and plentiful rainfall, such detailed crop monitoring might not be useful or economical. But in the western United States, where much of the water comes from underground aquifers, conserving water, and more importantly, conserving the electricity that pumps it to the surface and across fields, could save farmers hundreds of thousands of dollars each year.
在那些经常下雨、雨量充沛的地区，对作物实施如此细致的监控也许不是很有用，也不经济。但在美国西部，大部分水来自地下蓄水，省水，更重要的是，省下人们把水抽到地表再一一浇灌田地的用电，每年能为农民节约数十万美元。
