Nuts! All the fun ones got answered among the four that Byron asked about
cow[manure] per the NMSU
The last question was what the fertilizer rating in the common 3 number
system would be. Total nitrogen would be organic or Kjeldahl plus the
inorganic. Since the Kjeldahl is 1.74% and the inorganic is 87 ppm, that
is .0087 % or sort of enough to make the first number around 1.75 (1.7487).
The P would be the % phosphorus or 0.45% and the K would be the potassium
number, 1.51
The standard rating for New Mexico cow[manure] is therefore 1.75 - 0.45 -
1.51.
