I’m making applications to orchard trees so my assumption would be that it takes more water to spread out the fertility – seeing it more as a volumetric measurement than surface area. But maybe @JohnWarmerdam has some insights into this. The trees are on large spacing (20′) so there’s definitely inefficiency. My only option as I understand it would be to run the tractor faster. But ensuring spray nozzles that are open are hitting their mark is another action I take. My sprayer is a pul-blast type.
