Precision agriculture is a way of thinking about how to improve production and get more from existing resources. It often involves the use of technology. An example found mostly in wealthier countries is a computer-guided tractor. The computer does most of the driving. 精细农业是谋划如何提高产量，以及从现有资源中获取更多回报的一种方式。它通常涉及到技术的运用。富有国家常见的一个例子就是使用电脑操纵的拖拉机。计算机负责大部分的驾驶工作。
