    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.

    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 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.

    My best to you

        Your comment makes sense to me.  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.

        Be well, George

        Ruminations after a morning pruning.  The weather is
        ideal.  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.
