 ANALYSIS OF OFFICIAL FERTILIZER SAMPLES IN KENTUCKY JULY 1977 - JUNE 1978 7
`  INTRODUCTION
This bulletin presents the results of analyses of 2,119 official samples of
commercial fertilizer taken during the period July 1, 1977 through June 30, 1978 by
the field inspection staff. These samples represented approximately 27,000 tons of
fertilizer out of the approximately 989,000 tons sold during this period. The
Q regulatory laboratory made 1,971 nitrogen, 1,979 phosphorus, 1,984 potassium, and
about 720 chloride, secondary, and minor element analyses on these samples. The
results of N, P205, and K20 analyses of samples of mixed fertilizers and fertilizer
` materials are in Table 1. An indication of the variation of the N, P205, and K20
% found among the samples from a specific grade of a specific manufacturer 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, 1978.
EXPLANATION OF TABLES
A TABLE 1.
Every official sample taken during the year of a fertilizer with a guarantee
for N, P205, or K20 is listed in this table. A comparison of the "GRADE" with the
laboratory analysis for nitrogen (N), available phosphoric acid (APA), and potash
(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
A calculated:
_ A 5-10-15 fertilizer is guaranteed to contain 5% N, 10% P205, 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 P2O5, and 2
for KZO. Thus, the "Guaranteed Value" of the 5-10-15 is calculated as follows:
" Element Guaranteed, % FEE EL.;
l N 5.0 X 4 = 20.0
P205 10.0 X 3 = 30.0
KZO 15.0 X 2 = 30.0
` Total "Guaranteed Value" = 80.0
r

 8 REGULATORY BULLETIN 226 ~
The same procedure is followed for the "Found Value", thus:
Element Found, % fggtgg Vglgg
N 5.l X 4 = 20.4 .
P205 lO.2 X 3 = 30.6 ,
KZO l5.l X 2 = 30.2
Total "Found Value" = Bl.? l
The relative value (RV) is then computed by dividing the "Found Value" by the
"Guaranteed Value" and multiplying by l0O:
RV = (8l.2/80.0) X l0O = lOl.5% ;
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 inconsistant in its marking. For example, two samples
that are guaranteed lO% PZOB (APA) may both be shown as containing 9.3%. 0ne of these S.
may have an asterisk (*) and the other not. There are two situations which may cause
this apparent difference: (
(l) 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. 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% P2O5 .
and ll.2% KZO. The grade would be printed 0-ll-ll. However, the tolerances are
calculated on the 11.9% and ll.2% guarantees. If this custom mixed fertilizer analyzed
ll.O% P205 and lO.9% KZO, only the 11.0% PZOS would be marked (*) because it is below
tm H.%'wamnwebymwetmntm mlmame. i
The column headed "NUM" lists the laboratory number of the particular sample. In _ l
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.
Ei
The data in this table snow the average analysis (AA) and coefficient of variation i
(CV) for certain grades and the average percentage of guarantee (Z of GUAR.) and
appropriate CV for all grades sampled for certain companies. An entry 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.

 u ANALYSIS OF OFFICIAL FERTILIZER SAMPLES IN KENTUCKY JULY 1977 - JUNE 1978 9
* 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 10 analyses of a fertilizer guaranteed to contain 5% nitrogen:
The formula for computing the coefficient of variation (CV) is:
gh CV = (S/M) X 100
where S = standard deviation
M = average found analysis
The formula for computing S is:
` s = i [ xx? - (xx)2gn
Q n - 1
where X = an individual found analytical result
U n = number of analyses
X means "Sum of ....... "
Now in our example n = l0 and lets assume that the 10 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? = 5.62 + 6.62 +   + 6.32 = 306.49
‘ (:X)2 = (55.3)2 = 3058.09
s =  = 0.276
The average found analysis, M, is computed as follows:
M = (5.6 + 5.5 + ... + 5.3)/l0 = 5.53
Using S and M, the CV can now be computed:
A CV = (0.275/5.53) X 100 = 5%
If, in this example, there had been less variation or "scatter", the resulting percentage
(CV) would have been smaller. lf 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.
A 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 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
t 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 6
` samples reported in Table 1 that were excluded from the CV computations reported in

 10 REGULATORY BULLETIN 226 {
Table 2. As a basis for excluding these samples, the following rules were generally 7 .
followed.
l. Throw out any samples more than 120% or less than 80% in relative value except:
a. Those within j_20% of the average sample value, or ri
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:
a. Whose ratio strongly suggests an entirely different grade of fertilizer, or 2
b. Nhere 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 Explanatory)
INSPECTION AND ANALYTICAL TOLERANCE
n
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 V
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. T
IF "FOUND" j_"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" is equal to 3% of the "GUARANTEE" plus 0.4. For example, the tolerance on
a 12% guarantee is 12 X 0.03 + 0.4 = 0.76. Any found value of 11.24% or less was Y
declared deficient (12 - 0.76 = 11.24%). The relative value (RV) was considered _
deficient when it was more than 2.5% below 100%. 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 1.5%. Samples were considered excessive in chlorine i
(XS CL) if they analyzed more than 0.5 above the maximum guaranteed percentage.

° A product was considered deficient in ca1cium (Ca), magnesium (M9). 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
Q samp1e ana1yzed Tess than or equa1 to 0.8 X “GUARANTEE". The product was considered
V r
excessive, "E", if the samp1e ana1yzed as much or more than 2 X "GUARANTEE“ for any of
- these e1ements.
In some samp1es a deficiency in one nutrient was accompanied by an overrun in
another. This may be evidence of segregation, incomp1ete mixing, or incorrect weighing
by the manufacturer. Extreme variations of this kind, however, cannot be who11y
it
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.
