it, or water of different temperatures, will put our at different rates.<o:p></o:p></span></p>

<p class="MsoNormal">Since I upgraded my tractor this winter, I plan on recalibration and this is the method I plan to use. Adjust the nozzles and the tractor speed until I feel I get adequate coverage of the trees. I will then fill my tank with 50 gallons
of water, and spray it over a prescribed route. When the tank is empty, I calculate the acres sprayed. From that I can determine the number of gallons per acre. To that number of gallons, I will add the chemical required per acre. Since we are high density,
well pruned, I multiply by .7 (captan: 6# x .7= 4.2 #). If I travel the same route, I will get the required spray per acre. <o:p></o:p></p>

<p class="gmailmsg">Hello all, need some healthy practical advice on sprayer calibration. 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.<o:p></o:p></p>
<p class="gmailmsg">need a simple but effective solution...any takers?<o:p></o:p></p>

of varieties and improved planting system encourage 5% renewal in my opinion. <o:p></o:p></p>

is why high density systems can have a longer productive life than less dense orchards.<o:p></o:p></p>
