Mission It is our goal to emphasize the "Service" portion of our department name. So, if we can be of further service, please do not hesitate to call, write or contact us by e-mail. Fertilizer investigational allowances are 10 % or two units for all primary nutrients or 3% relative value. Relative value (RV) is calculated:
RV =
(Found((Nitrogen X 2)+(Available Phosphate X 2)+Soluble Potash))
------------------------------------------------------------------------ X 100
(Guaranteed((Nitrogen X 2)+(Available Phosphate X 2)+Soluble Potash))
Ag Liming Material investigational allowances are 90 %
passing a U.S. #8 sieve and calcium carbonate equivalent
(CCE) 65% minimum.
Sieve sizes used to determine effectiveness of the material
are #8, #40, and #60. Effective Neutralizing Material
(ENM) is calculated by assigning values to the retained
portions. Material retained on the #8 has no value,
material retained on #40 is allowed 25%, material retained
on #60 is allowed 60%, while material passing the #60 is
allowed 100%. These assigned percentages are added in the
collected term, Fineness Factor (FF). ENM for the
individual sample is calculated:
% CCE FF
ENM = --------- X --------- X 800
100 100
Effective Magnesium (EMg) content is calculated:
% Mg FF
EMg = --------- X --------- X 2000
100 100
Stockpile rolling average is calculated by averaging the last three samples secured from the sampled stockpile. |
