The article focuses on variable-rate irrigation. Variable-rate irrigation could make center pivots much more efficient users of water, especially where there are non-crop areas or variations in soil type or crop mix under the watering circle. Calvin Perry, research and Extension engineer noted that those conditions are prevalent in South Georgia. According to him, variable-rate irrigation has an especially good fit in South Georgia, where there are around 10,000 center pivots, many of which are partial pivots or pivots which overlap with others. With tree lines, neighboring fields and riparian zones often intruding into the circle, putting in a pivot often is like putting a round peg in a square hole.

    For trickle irrigation systems to deliver improved water- and nutrient-use efficiency, distance between emitters and emitter flow rates must be matched to the soil's wetting characteristics and the amount and timing of water to be supplied to the crop. Broad soil texture ranges (e.g. sand, loam,...
