 6 REGULATORY BULLETIN 196
This bulletin contains results of analyses of 3,030 official samples
of commercial fertilizer made during the period January l through June 30,
l967.
Separate tables are provided for the results of the analyses for nitro-
gen, available phosphoric acid and soluble potash, organics, unacidulated
phosphatic material, boron, secondary and micro nutrients, and aldrin in
fertilizer.
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 "N" "APA" and "POT".
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
following examples illustrate how this relative value is calculated: A
A 5-l0—l5 sulfate fertilizer is guaranteed to contain 5 units of nitrogen,
l0 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 l 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 ol Available Phosphoric Acid x Z = 20.0
l5.0 Units of Potash x 1 = 15.0
Total computed guaranteed value 50.0
The same procedure is followed for "found values". Assuming a sample
of 5·lO—l5 was found to contain 5.l units of nitrogen, l0.2 units of avail-
able phosphoric acid and l5.l units of potash, the relative found value is
computed:
5.1 Units of Nitrogen x 3 = 15.3
l0.2 Units of Available Phosphoric Acid x 2 = 20.4
l5.l Units of Potash x l = 15.1
Total computed value 50.8
50.8 (computed found value of sample) divided by 50.0 (computed guar-
anteed value) times 100 (to arrive at percentage) gives l0l.6 as the percent
of relative value found.
fhc analyses indicated by an asterisk are deficient more than the
tolerance. Occasionally an analysis may be found that appears to be in-
consistent in its marking. For example, two samples that are guaranteed
l0Z available phosphoric acid may both be found to contain 9.7Z. One of
these may have an asterisk and the other not. There are two factors that
any cause this difference.
l. These tolerances are calcvlated by an electronic computer and applied
te the laboratory analyses before these data are rounded off to the nearest
tenth of a percent. ln the above example, the laboratory found 9.66% for
one sanple and 9.73] 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 -l1.9—1l.2. The grade would be written 0-11-ll. However,
the tolerances are calculated on the 11.9% and 11.2% guarantees.
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.
The use of a high speed computer to make these calculations enables us
to apply these tolerances more precisely than has been possible before.
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. ·
EXPLANATION OF CERTAIN COLUMNS
The letters NIT after a grade means that the product is, or that it
contains Nitrate of Potash. The N/B after a grade indicates 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. 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. The PHYS column shows
the physical form of the fertilizer when sampled.
The first digit indicates: 1 = chemically combined
2 = dry blend
The second digit indicates: l = pulverized, bag
‘ 2 = pulverized, bulk
3 = semi-granular, bag
A = semi—granular, bulk
5 = granular, bag
6 = granular, bulk
7 Z pellet, bag
8 = pellet, bulk
9 = liquid
0 = slurry
Example: Chemically combined, granular, bag = 15

The listing on pages IZ thru 23 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 24 thru 27 is a summary 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 Nitorgen 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
I 5.0 5.5 30.25
J 5.0 5.3 28.09
55.3 306.49
10 Samples, average analysis = éggé = 5.53

Standard deviation = \ / 306.49 - ééég _ \/ 0.68 = 0.275
_ 9
10 - l
V Coefficient of variation = 0.275 x 100 = 4.97 - 5.0%
5.53
If in this example there had been less variation or "scatter", the resulting per-
centage would have been smaller. If there had been more variation, it would have been
larger. The coefficient varies directly with the range in values of analyses.
