What does head-to-head spacing refer to?

Head-to-head spacing refers to the spacing of spray or rotary heads being equal to the manufacturer's published radius of the head. This practice ensures that the water coverage provided by one irrigation head overlaps with that of another, leading to uniformity in water distribution across the irrigated area. By using this spacing method, operators can prevent dry spots where plants may not receive adequate moisture and eliminate areas of overwatering that can lead to runoff or water wastage. Proper head-to-head spacing is essential for achieving efficient irrigation, reducing water costs, and promoting healthier plant growth.
