 4 REGULATORY BULLETIN 180
This bulletin contains results of analyses of 3, 850 official samples of
commercial fertilizer made during the period January 1 through June 30,
1963. The average analysis of each plant food element and the coefficient of
' variation for each plant food are shown in Tables 1 and 2 for each plant. All
Nil
  Separate tables are provided for the results of analyses ofmixed dry fer- P.
1 tilizer, mixed 1iqui`d fertilizer, custom-·mixed fertilizer, straight materials, Ho
I boron, pesticides incorporated in fertilizer and for the percent of potash
V equivalent to excess muriate where the guarantee for Sulfate of Potash is not An
met. A summary of the results of the analyses of 26 magnesium samples and lO(
5 zinc samples is given on page 168. NB
EXPLANATION OF TABLES AY`!
As
The information given in the following tables should be useful in deter- P-
mining how nearly a manufacturer is meeting the chemical guarantee printed PT
on the bag or tag for the fertilizer represented by the samples listed. This ,
may be done by comparing the guarantee shown at the beginning of each listing Ar
of samples with the actual analysis in the column at the right interms of nitro- V 351
gen, available phosphoric acid and potash. At]
An additional means of comparing guarantees with the analyses ofsamples B8
is in the percent of relative value found, shown in the extreme right-hand col- H0
umn. The following examples illustrate how this relative value is calculated: K*’
A 5-10-15 sulfate fertilizer is guaranteed to contain 5 units of nitrogen, BH
1O units of available phosphoric acid and 15 units of potash. Factors for com- 10*
puting the relative value of these plant foods are; 3 for nitrogen, 2 for avail- OV
able 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 DC
10.0 Units of Available Phosphoric Acid x Z : 20. 0
15.0 Units of Potash x 1 : 15.0 Bl
'l`ota1 computed guaranteed value 50.0  
1
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 available Bl
phosphoric acid and 15. 1 units of potash, the relative found value is computed; gl'
e
5.1 Units of Nitrogen x 3 : 15, 3 ‘
10. 2 Units of Available Phosphoric Acid x 2 : Z0. 4 BE
15.1 Units of Potash x 1 : 15.1 ` QJ
Total computed value 50. 8 L5
50. 8 (computed found value of sample) divided by 50.0 (computed guar- BL
anteed value) times 100 (to arrive at percentage) gives 101. 6 as the percent of Rl,
t relative value found. Lt
ln some samples a deficiency in one nutrient is accompanied by an over- CE
run in another nutrient. This maybe evidence of improper mixing or weighing L)
by the manufacturer. Extrerne variations of this kind cannot be attributed to R1
separation of materials (segregation) after the product is bagged though this  
may be a minor factor. Excess of one nutrient cannot compensate for defi- (3*
ciency of another nutrient. The purchaser is entitled to receive the full g\1{\1‘- lf;
antee forall nutrients as expressed by the manufacturer’s guaranteed analysis. lm
The results of analyses of all inspection samples are given in tables 1, L.
3, 4. 5 and 6. lf an analysis shows a deficiency of more than the tolerance in
the amount clainied for nitrogen. phosphoric acid or potasli, or if the percent
of the relative value is 97 or lvss. the result is indicated by an asterisk

 8 REGULATORY BULLETIN 180
VARIATION I`N FERTILIZER ANALYSES
Variation is a basic trait in the analysis of fertilizer. The guarantee
‘ printed on fertilizer bags cannot be acc epted as an exact statement of the
chemical contents. Rather, it tells what the manufacturer was aiming for and
what the purchaser hopes to buy. This is true of all fertilizers. There is al-
! ways variation around some average analysis.
Many causes contribute to variability. Pa r tic l e size and variability in
chemical content of raw materials are an initial cause of variation. Methods
of assembling, weighing, mixing, delivery into storage piles, and re-handling,
including bagging, present further opportunities for variation. To some ex-
tent they may cancel each other and thus minimize variation. They may pro-
gressively accumulate and thus magnify variation. .
The degree of variability in the final fertilizer product is in direct ratio
to the variation introduced from these causes combined with the careexer- `
cised. Precision comes only through the use ofproperly classified ingredients,
employment of methods that are reasonably exact and carefulness at all stages
of manufacture.
What has been said of manipulation in manufac tur e is likewise true of
taking samples, their handling and analysis in the laboratory. This, too, may
contribute to variation. Differences from this source, like those broughtabout
in the manufacturing process, may tend to cancel each other or can accumu-
late. As in manufacturing, care and precision in the manipulation of samples
will reduce the degree of variability.
For the purpose of this report, variations attributable to sampling and
the laboratory may be disregarded. They are usually slight. Also all sam-
ples were taken by the same inspectors and handled in the laboratory in the
same way. lf there is "laboratory bias" it will be to change all results in the
same directions to the same degree.
WHY A CONCERN FOR VARIABILITY?
The manufacturer and the farmer alike are interested in this question of
variability. Producers of fertilizer as well as purchasers want a product fully
meeting guarantee. Manufacturers know that a certain amount of variability is
unavoidable. This is a factor in suggesting "over-formulation" in the industry.
The matter of how much over-formulation is necessary varies widely from I
plant to plant. The aim or objective of manufacturing is to have full guarantee
as shown on every bag. lf there is variability, it should be confined to values
above the guarantee.
From the user‘s viewpoint, if fertilizer is variable, some purchasers will
get less than they pay for and others will get more. Also, with variability in
. composition, different areas in the field will be treated differently correspond-
. ing to the degree of variability. The user, therefore, is interested in vari-
ability to the extent that he gets what he pays for, and the fertilizer is suffi-
ciently uniform to give the best possible agronomic return.
The fertilizer control official is likewise interested in this. His task is to  i
see that each bag of fertilizer or the average of any two bags or whatever unit
is selected is r eas onabl y similar to other units of quantity sold by a given
manufacturer. Fertilizer laws infer that the ave rage of the whole lot pur-
chased should be at least equal to the guarantee. Although there are tolerances
permitting some samples to fall slightly under guarantee, these tolerances are
not large.

 COMMERCIAL FERTILIZER IN KENTUCKY, SPRING SEASON 1963 9
REPORTING THE ANALYSES OF FERTILIZER '
3¤t€€ Some system of characterization is desirable if the chemical analyses
nf the publi s hed in regulatory bulletins are to be meaningful. Marking deficient `
r and samples with an asterisk is one of these. Since 1961, two additional ways of
.5 al- diagnosing such data have been used.
AVERAGE ANALYSIS, A MEASURE
.ity in
thgds The statement has been made that the average of a given lot of fertilizer
iling_ should at least equal the guarante e. If this is c or r e c t, an average of the
B gx- analyses of several samples of such a lot will show whether or not this is true.
ro-  —
P ‘ The printed guarantee on each bag is viewed as the "aim" of the manu-
facturer. The average analysis of actual samples of the fertilizer becomes the
ratio T means of statistically measuring the manufacturer‘s "true aim." The average
mm-- analysis has been calculated for all of the analyses of mixed fertilizers re-
_€n[s’ ported in this bulletin when as many as two samples are shown. These aver-
tages ages, given in Tables l and Z, follow the words "average analysis. " V
MEASURING VARIABILITY
ue of
may "Average analysis" as an expression of the "true aim" of a manufacturer,
about says nothing in the dimension of variability. Some measure is needed to ex-
umu- press the range in analyses on either side of the average. To further use the
nples analogy from marksmanship if "average" measures aim at the target and tells
the center of this aim, another measure is needed to express the "scatter" of
the various shots. Are they close to the center of "true aim" or are they
; and "wide" of the mark?
sam-
,1 the The coefficient of variation is proposed as a means for reducing this to a
n the Statistic that is useful. The method for doing this will be found in textbooks on
statistics and when applied to a guarantee of 5% nitrogen is calculated as fol··
lows:

 10 REGULATORY BULLETIN 180
"WILD" SAMPLES T
No matter how much care is exerted ina fertilizer plant, an occasional
· "wild" sample may appear. Such samples are caused by unusual circum-
stances such as putting the wrong fertilizer in bags labeled for another grade W
or large errors in mixing or manipulation in the factory that cannot be said to
E represent usual procedure.
Computations that include such samples would only throw the coefficient A
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 only 60 such samples in the mixed fertilizer samples
reported. Such samples are indicated in the table as "See Note 9. " As a basis
for excluding these samples, the following rules were followed:
l. Throw out any samples more than 110% or less than 90% in relative
value except:
a. The sample is within i 10% of the average sample value.
b. The variation of all the sample values is such that the samples
more than + 10% appear to fit a normal distribution pattern.
Z. Throw out all of a small group of less than (5) samples if variability
is so great that no clear pattern is apparent.
3. Throw out individual samples whose ratio of ingredients differs
strongly from the balance of samples of the grade. These may in-
clude samples:
a. Whose ratio strongly suggests an entirely different grade of fer-
tilizer.
b. Two or more of whose ingredients are higher or lower by 10% or
more of the extreme values of the remaining normal samples.
NOTE ON METHODS OF COMPUTATION USED
It is apparent that the computation of coefficients of variation and even
the simple ave rage s for a large number of samples requires a great many
mathematical operations. The cost would make the operation impossible by
ordinary methods, but the use of the digital computer leased by the University
of Kentucky enables all of the c omputations to be performed at a rate of
approximately 5,000 samples an hour.
The machine program for this work was developed especially for the pur-
pose and is available for use on the computer at the University of Kentucky. It
will be duplicated for use on other IBM 650 or 1620 computers at no charge.
INFORMATION GIVEN IN TABLES
` The coefficients of variation for each grade from each plant are indicated
in Tables 1 and Z. These are calculated for mixed fertilizer only and are
shown when two or more samples of a grade are reported. The coefficients of
variation become more significant as the number of samples increases.
