Definitely. While having ample rainfall is obviously a huge advantage, rain is never timely enough or consistent enough to allow the crop to reach its full yield potential. This is even more evident with sandy soils that have a lower water holding capacity. On top of that, drip is also a nutrient delivery system that allows you to fertigate and control the nutrient levels in your soil in a precise and economical way. Applying all of your fertilizer in just a few applications can be wasteful, especially under rainy conditions that provoke leaching. Splitting your nutrient application throughout the season guarantees that your corn crop  gets what it needs when it needs it. This is what makes drip systems the perfect tool for increasing productivity in previously rain-fed plots.
