<div><div>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. </div></div><div><br></div><div>A different question: my new tractor has an enclosed cab (no more monkey suit), with an activated charcoal filter.

<p class="gmail_msg">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.</p>
<p class="gmail_msg">need a simple but effective solution...any takers?</p>
<p class="gmail_msg">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.</p>

<div class="gmail_msg">I agree that it's great to be out pruning. 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. </div>

pruning. The weather is ideal. The
temps are in the high 20's, the wind

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.</div>
