 ANALYSIS OF OFFICIAL FERTILIZER SAMPLES IN KENTUCKY JULY 1976 - JUNE 1977 5
INTRODUCTION
This bulletin presents the results of analyses of 2,703 official samples of
commercial fertilizer taken during the period July 1, 1976 through June 30, 1977
by the field inspection staff. These samples represented approximately 35,000
tons of fertilizer out of the approximately 1,100,000 tons sold during this period.
The regulatory laboratory made 2,477 nitrogen, 2,541 phosphorus, 2,518 potassium,
and about 860 chloride, secondary, and minor element analyses on these samples.
The results of N, P205, and K20 analyses of samples of mixed fertilizers and
v fertilizer materials are in Table 1. An indication of the variation of the N,
P205, and KZO found among the samples from a specific grade of a specific manu-
facturer is in Table 2. Table 3 contains the results of secondary and minor
element analyses and Table 4 is a listing of fertilizer registrants for Kentucky
· as of June 30, 1977.
- EXPLANATION OF TABLES
TABLE 1.
Every official sample taken during the year of a fertilizer with a guarantee
for N, P205, or KZO is listed in this table. A comparison of the "GRADE" with the
laboratory analysis for nitrogen (N), available phosphoric acid (APA), and potash
g (POT) will show how closely the manufacturer met his chemical guarantee. An
_ additional way of comparing guaranteed with the found analysis is with the relative
value shown in the column headed RV. The following example illustrates how this
relative value is calculated:
( A 5-10-15 fertilizer is guaranteed to contain 5% N, 10% PZOS, and 15% K20.
A "Guaranteed Value" and a "Found Value" are computed for this fertilizer by
_ assigning arbitrary values to the individual nutrients as follows: 4 for N, 3 for
P205, and 2 for K20. Thus, the "Guaranteed Value" of the 5-l0—l5 is calculated
as follows:
Element Guaranteed, % facto; Value
N $.0 x 4 = 20.0
~ PZO5 10.0 X 3 = 30.0
KZO 15.0 X 2 = 30.0
Total "Guaranteed Value" =· -00iO
n

 6 REGULATORY BULLETIN 224
The same procedure is followed for the "Found Value", thus:
Element Found, % fggtg; Vglgg '
N 5.l X 4 = 20.4
PZOS lO.2 X 3 = 30.6 ( .
KZO l5.l X 2 = 30.2
Total "Found Value" = FET?}
The relative value (RV) is then computed by dividing the "Found Value" by the
"Guaranteed Value" and multiplying by l0O: i
RV = (8l.2/80.0) X l0O = l0l.5% A
The RV is rounded to the nearest whole percent before being printed in the bulletin.
Those results marked with an asterisk (*) are deficient under the criteria
stated in the Inspection and Analytical Tolerance section (page 8). Occasionally °
an analysis may be found that appears to be inconsistent in its marking. For example,
two samples that are guaranteed lO% P2O5 (APA) may both be shown as containing 9.3%.
One of these may have an asterisk (*) and the other not. There are two situations
which may cause this apparent difference:
(T) The tolerances are calculated by computer and applied to the laboratory `
analyses before the data are rounded to the nearest tenth of a percent and printed. J
In the above example, the laboratory found 9.27% for one sample and 9.33% for the
other. Only the first one would be marked (*) as deficient.
(2) The grade as printed is the largest whole number in the guarantee of each
ingredient. For example, a custom-mixed lot of fertilizer may be guaranteed ll.9%
P205 and ll.2% KZO. The grade would be printed O-ll-ll. However, the tolerances
are calculated on the ll.9% and ll.2% guarantees. If this custom mixed fertilizer
analyzed ll.0% PZOB and l0.9% K20, only the ll.0% PZOS would be marked (*) because S
it is below the ll.9% guarantee by more than the tolerance.
The column headed "NUM" lists the laboratory number of the particular sample.
In the column headed "XS CL", an asterisk (*) indicates that the chlorine content —
of the sample exceeded the maximum chlorine guarantee of the field crop tobacco
fertilizer. A
TABLE 2. ~
The data in this table show the average analysis (AA) and coefficient of
variation (CV) for certain grades and the average percentage of guarantee (% of
GUAR.) and appropriate CV for all grades sampled for certain companies. An entry

 ANALYSIS OF OFFICIAL FERTILIZER SAMPLES IN KENTUCKY JULY l976 - JUNE l977 7
was made in this table for a company when one grade was sampled 5 or more times
or l0 or more total samples were obtained.
The coefficient of variation is proposed as a useful means for describing
variation among samples. The method for doing this will be found in textbooks on
statistics and will be illustrated for l0 analyses of a material guaranteed to
contain 5% nitrogen:
The formula for computing the coefficient of variation (CV) is:
~ CV = (S/M) X l00
where S = standard deviation
M = average found analysis
The formula for computing S is:
S = (/ZX? - (XX)?/n
· n - l
where X = an individual found analytical result
r n = number of analyses
Z means "Sum of ....... "
Now in our example n = l0 and lets assume that the l0 X's are 5.6, 5.5, 5.4,
5.7, 5.5, 5.8, 5.0, 6.0, 5.5, and 5.3.
· xx? = 5.52 + 5.52 + ... + 5.22 = 306.49
(zx)2 = (55.3)2 = 3058.09
s = u1§0ETT§Fi`?iE§ T097TOT79 = 0.275
` The average found analysis, M, is computed as follows:
M = (5.5 + 5.5 +   + 5.3)/io = 5.53
_ Using S and M, the CV can now be computed:
CV = (0.275/5.53) X lOO = 5%
If, in this example, there had been less variation or "scatter", the resulting percentage
# (CV) would have been smaller. If there had been more variation, it would have been
larger. The CV varies directly with the range in values of analyses and inversely
with the average analysis.
No matter how much care is exerted in a fertilizer plant, an occasional "wild"
` batch may appear and subsequently be sampled. Such batches are caused by unusual
W` circumstances such as putting the wrong fertilizer in bags labeled for another grade
or large errors in mixing or manipulation in the factory that cannot be said to
represent usual procedure. Computations that include such samples would only throw
the coefficient of variation as well as the average analysis completely out of line.
\ ) They are judged to be so abnormal that they have not been included in these
· statistical determinations. There were 35 samples reported in Table l that were

 8 REGULATORY BULLETIN 224
excluded from the CV computations reported in Table 2. As a basis for excluding
these samples, the following rules were generally followed. ’
l. Throw out any samples more than 120% or less than 80% in relative value except: _
a. Those within i 20% of the average sample value, or
b. when the variation of all the sample values is such that the questionable
sample appears to fit a normal distribution pattern.
2. Throw out any sample whose ratio of ingredients differs strongly from the
balance of samples of that grade. These may include samples: 3
a. whose ratio strongly suggests an entirely different grade of fertilizer, or V
b. where two or more of its ingredients are higher or lower by 20% or more of
the extreme values of the remaining normal samples.
TABLE 3 and 4. (Self Explantory)
INSPECTION AND ANALYTICAL TOLERANCE
A tolerance is allowed for variations that may occur in sampling and chemical
analyses. It does not, nor is it intended to allow for variation in the manufacturing
process. The manufacturer should compensate for variability in manufacturing techniques
and materials when calculating the formula for a given analysis. `
The following formula was used to identify those samples of mixed fertilizers
which were considered to be deficient in N, P205, and K20.
IF "FOUND" g_"GUARANTEE" — "TOLERANCE" THEN "FOUND IS DEFICIENT"
where: "TOLERANCE" = "GUARANTEE" X 0.03 + 0.4
In words this is: If the "FOUND" analysis is less than or equal to the "GUARANTEED"
analysis minus the "TOLERANCE" then the "FOUND" analysis is deemed deficient. The
"TOLERANCE" was equal to 3% of the "GUARANTEE" plus 0.4. For example, the tolerance on
a l2% guarantee is l2 X 0.03 + 0.4 = 0.76. Any found value of ll.24% or less was [
declared deficient (l2 - O.76 = ll.24%). The relative value (RV) was considered ‘
deficient when it was more than 2.5% below l00%. Specifically, if the RV was less .
than 97.5% it was considered deficient. .
Fertilizers sold for use on field crop tobacco must carry a maximum chlorine
guarantee which can be no more than l.5%. Samples were considered excessive in l
chlorine (XS CL) if they analyzed more than 0.5 above the maximum guaranteed
percentage.

 ANALYSIS 0F OFFICIAL FERTILIZER SAMPLES IN KENTUCKY JULY 1976 — JUNE 1977 9
A product was considered deficient in ca1cium (Ca), magnesium (Mg), su1fur (S),
boron (B), and iron (Fe) if the samp1e ana1yzed 1ess than or equa1 to 0.9 X
"GUARANTEE"; and, deficient in copper (Cu), manganese (Mn), mo1ybdenum (Mo), and
zinc (Zn) if the samp1e ana1yzed 1ess than or equa1 to 0.8 X "GUARANTEE". The
product was considered excessive, "E“, if the samp1e ana1yzed as much or more than
2 X "GUARANTEE" for a11 these e1ements.
In some samp1es a deficiency in one nutrient was accompanied by an overrun in
another. This may be evidence of segregation, inc0mp1ete mixing, or incorrect
weighing by the manufacturer. Extreme variations of this kind, however, cannot
be who11y attributed to segregation which occurs after the product is mixed
a1though this may be a factor. Excess of one nutrient wi11 not be a11owed to
compensate for a deficiency of another. The purchaser is entit1ed to receive the
fu11 guarantee for a11 nutrients as expressed by the manufacturer's guaranteed
ana1ysis.
