Precision Farming, Variable Rate Application Technology (VRT).


Population growth and pollution of water resources as a result of various human activities are fast getting the world to a point where availability of water, as opposed to land, is becoming a limitation to agricultural productivity. Consequently, farmers, agronomists, engineers and other stakeholders are examining the efficiency of water-use in agriculture and are developing technologies meant to improve agricultural water-use efficiency. Precision farming is one such innovation. This paper makes a case for the implementation of precision farming as a strategy to improve agricultural water-use efficiency. Implementation of precision farming would not only lead to a significant reduction in agricultural water requirement but would also reduce agriculture’s impact on the environment.
