 C MMERCIAL FERTILIZER IN KENTUCKY, JULY, 1970 - JUNE, 1971 5
This bulletin contains the results of analyses of 2,082 official samples
of commercial fertilizer made during the period July 1, 1970 through June 30,
1971.
Separate tables are provided for the results of the analyses for nitro-
gen, available phosphoric acid and soluble potash, organics, boron, and
— secondary and micro nutrients.
EXPLANATION OF TABLES
The information given in the following tables should be useful in deter-
mining how nearly a manufacturer is meeting the chemical guarantee printed
on the bag or tag for the fertilizer represented by the samples listed. This
may be done by comparing the "grade" with the actual analysis listed under
An additional means of comparing guarantees with the analyses of samples
is in the percent of relative value found, shown in the column RV. The fol-
lowing examples illustrate how this relative value is calculated:
a 5-10-15 sulfate fertilizer is guaranteed to contain 5 units of nitrogen,
10 units of available phosphoric acid and 15 units of potash. Factors for
computing the relative value of these plant foods are: 3 for nitrogen, 2 for
available phosphoric acid and 1 for potash. Thus the combined guaranteed value
of the product represented is calculated:
5.0 Units of Nitrogen x 3 = 15.0
10.0 Units of Available Phosphoric Acid x 2 = 20.0
15.0 Units of Potash x l : 15.0
Total computed guaranteed value 50.0
_ 7 The same procedure is followed for "found values." Assuming a sample
of 5-10-15 was found to contain 5.1 units of nitrogen, 10.2 units of avail-
able phosphoric acid and 15.1 units of potash, the relative found value is
computed:
5.1 Units of Nitrogen x 3 = 15.3
10.2 Units of Available Phosphoric Acid x 2 = 20.4
15.1 Units of Potash x 1 = 15.1
Total computed value 50.8
' 50.8 (computed found value of sample) divided by 50.0 (computed guaranteed
value) times 100 (to arrive at percentage) gives 101.6 as the percent of rela-
tive value found.
The analyses indicated by an asterisk are deficient more than the toler-
ance. Occasionally an analysis may be found that appears to be inconsistent
in its marking. For example, two samples that are guaranteed 10% available
phosphoric acid may both be found to contain 9.77. One of these may have an
asterisk and the other not. There are two factors that may cause this differ-
ence.
(Continued)

 6 REGULATORY BULLETIN 207
1. These tolerances are calculated by an electronic computer and applied
to the laboratory analyses before these data are rounded off to the nearest <
tenth of a percent. In the above example, the laboratory found 9.66% for
one sample and 9.7b% for the other. The first one would be starred as de-
ficient.
2. The grade is written by using the largest whole number in the guarantee
of each ingredient. For example, a custom-mixed lot of fertilizer may be
guaranteed 0 -11.9-11.2. The grade would be written O-11-ll. However, the
tolerances are calculated on the 11.9% and 11.2% guarantee.
If this fertilizer analyzed 11.3% A.P.A. and 10.9% potash, the 11.3%
A.P.A. would be starred because this analysis is 0.6% units below the 11.9%
guarantee.
In some samples a deficiency in one nutrient is accompanied by an over-
run in another nutrient. This may be evidence of improper mixing or weighing
by the manufacturer. Extreme variations of this kind cannot be attributed
to separation of materials (segregation) after the product is bagged though
this may be a minor factor. Excess of one nutrient cannot compensate for defi-
ciency of another nutrient. The purchaser is entitled to receive the full .
guarantee for all nutrients as expressed by the manufacturer's guaranteed
analysis. V
EXPLANATION OF CERTAIN COLUTWS
The letters NIT after a grade means that the product is, or that it
contains Nitrate of Potash. The W/B after a grade indicated that the sample
contained boron and the W/ME means that the sample was analyzed for secon-
dary and micro-nutrients. The column headed "Num" lists the laboratory
number of the particular sample. In the column headed "XS CL", an asterisk
indicates the sample did not meet the guarantee for sulfate of potash, The
RV column shows the percent of relative value found.

COMTUTING COEFFICIENT OF VARIATION
The listing on pages ll thru 18 shows the average analysis and coefficient of
variation for each grade where two or more samples of a grade are reported. These
data also show the average percentage of guarantee and the coefficient of variations
for all grades reported for a company, or plant, when more than one plant is listed
and ten or more samples are reported.
The listing on pages 19 thru 21 is a sum ary of the average percentage of guar-
antee and the coefficient of variation by plant and company.
The coefficient of variation is proposed as a means for reducing this to a sta-
tistic that is useful. The method for doing this will be found in textbooks on sta-
tistics and when applied to a guarantee of 5% nitrogen is calculated as follows:
Sample Number Nltorgen Guarantee Found Sguared
A 5.0 5.6 31.36
B 5.0 5.5 30.25
C 5.0 5.4 29.16
D 5.0 5.7 32.49
E 5.0 5.5 30.25
F 5.0 5.8 33.64
G 5.0 5.0 25.00
H 5.0 6.0 36.00
1 5.0 5.5 30.25
J 5.0 5.3 28.09
55.3 306.49
10 Samples, average analysis = 2%$2 = 5.53

Standard deviation = \ { 306.49 - égég = \/ 0.68 = 0.275
9
10 — 1
Coefficient of variation · 0.275 x 100 = 4.97 - 5.0%
5.53
lf in this example there had been less variation or "acatter", the resulting per-
centage would have been smaller. If there had been more variation, it would have been
larger. The coefficient varies directly wlth the range in values of analyses.

 COMM RCIAL FERTILIZER IN KENTUCKY, JULY 1970 - JUNE, 1971 ll
"WILD" SAMPLES
No matter how much care is exerted in a fertilizer plant, an occasional
"wild" sample may appear. Such samples 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 well as the average analysis completely out of line. They are
judged to be so abnormal they have not been included in these statistical deter- .
· minations. There were 18 such samples in the mixed fertilizer samples reported.
As a basis for excluding these samples, the following rules were followed:
l. Throw out any samples more than 120% or less than 80% in relative
value except:
a. The sample is within j 20% of the average sample value.
b. The variation of all the sample values is such that the samples
more than j 20% appear to fit a normal distribution pattern.
i 2. Throw out individual samples whose ratio of ingredients differs strong-
ly from the balance of samples of the grade. These may include samples:
a. Whose ratio strongly suggests an entirely different grade of fer-
tilizer.
b. Two or more of whose ingredients are high or lower by 20% or
more of the extreme values of the remaining normal samples.
