Specifically air blast sprayers. For decades we have measured a block of trees to determine acreage, sprayed out tank and determined gallons per acre based on what area was covered in tank. For example trees planted at 8 x 18 spacing gave us 300 trees to acre, we sprayed out tank, counted trees and determined that our sprayer puts out 2.5 acres per tank. we used this to determine amount of material to put in the tank etc. All the calibration formulas , I have seen require tree row volume(height x row spacing) to be part of equation. I have 4-5 different spacings in 100 acres of orchard which makes it more of a headache to constantly figure gallons per acre and spray materials needed in each different block(thus the reason we simply measured trees per acre). I know my speed , i know my gallons per minute but can't find an equation that converts this to gallons per acre without tree row volume. need a simple but effective solution...any takers? in Virginia we have plums in full bloom, fantasia and red gold nectarines in pink and some open blooms, 21 degrees forecasted on friday and saturday night.

I did use the word can to hedge the productive life of a block.

I disagree that you should expect a longer productive life with high density systems. My goal here is to be looking at replanting when the orchard reaches twenty years or so. New varieties, strains of varieties and improved planting system encourage 5% renewal in my opinion.

Right now I have a cold and I fell on the ice on Dec. 29th and I am still suffering. Pt may help but it may take a while. I suppose that you are enjoying the warmer weather.

The temps are in the high 20's, the wind is light and the sun is shining. Weather like this is why we live here. Permanent limbs ultimately and inevitably get too large. This is why high density systems can have a longer productive life than less dense orchards.
