The results of analyses of the official samples of the various
» grades of fertilizer sold in Kentuck Y durin 1939 show that thc
' 5 E
iertihzers usually equaled their gnaranties and that the deli- , A
ciencics, with few exceptions, were of a minor nature. The ton- i
nage was about the same as the average in Kentucky in normal 1
Fears, o1· 110,000 tons, but an additional quantity of about 36,000 "
tons of 20-percent and triple superphosphate was used by farmers I l
of the State under the Agricultural Adjustment Administration {
ofthe United States Department of Agriculture. ,
NUTRIENTS IN COMMERCIAL FERTILIZERS  
The price of a commercial fertilizer is based on the quantities
p of available nitrogen, phosphorus and potassium it contains and
these nutrients are usually called the primary nutrients, but
ill§1`€ are a number of secondary elements or nutrients, 111311}* IH

` LOW-GRADE FERTILIZERS UE
Many brands of low-grade 11llXO(—l fertilizers were sold to i m
farmers in Kentucky during the year. Of the total tonnage of » lt
mixed fertilizers sold in the State 111 1039, approximately 173,000  _ ln
' tons contained not more than 14 percent of nitrogen, phosphoric I lll
` acid Hlltl potash, and approxiniately 25,000 tons contained 16 ‘ il
percent or less. The purchase of sucl1 a tonnage of low-grade , Sl
, fertilizer represents a tremendous loss in actual cash as well HS i_ lll
disappointment to the farmers of Kentucky. This loss in actual ` All
1llOl1C)' is due to the fact that there are ee1·tain costs in piroducilly  , lll
a to11 of fertilizer, regardless of the plant-food content, such as  
handling, mixing, bags, freight, lax and other charges. The sav-  
ings by the farmers in buying high—grade fertilizers instead ot I
low-grade fertilizers, because of these costs, would 111ea11 10 to 15 Ll
percent. on their fertilizer bills, or $3.50 or $+1.00 a ton, o1· an il
estimated cost to the farmers of the State of $85,000 or more mr  
llllillly. For example, it takes 3 tons of a 2-8-Lt fe1·tilize1‘h* _
supply the same amounts of nitrogen, ])l1,0S11l1()1'lC acid Zllld p01H$ll 2,
as are contained in 2 tons of a 3-1.2-G fertilizer. At the p1‘eVHll· °
ing retail prices in Kentucky in 15130; ·
3 tons of 2-8-4 at $25.50 a ton cost $76.50
2 tons of L}-12-6 at $32.40 a ton cost $04.80  . S
Q The saving in buying the Isl-12-6 fertilizer is $11,70, or about 11 . 1,

and tons. If a larger proportion of high-grade fertilizer was sold in
lckv the State, the saving would be greater.
Zmis A ()tl1er costs of an economic nature to the farmers, due to the ·
,,0,,1 purchase of low-grade fertilizers, such as failure in crop produc- l
din tion, loss in labor, loss in, soil conservation, less income to meet
mm . the budget and similar losses, may be even larger than the f
and . actual loss in money sustained in buying low-grade fertilizers. ,
mp- Agronomy and soil experts, the National Fertilizer Association t
bmit . and control officials are united in, advocating the use of high-
mm grade fertilizers. `
the LOW-GRADE FERTILIZERS NOT RECOMMENDED
)g(m’ The Fertilizer llepartnient is of the opinion that, because of
i the cost of mixing and distribution, it is uneconomical for farmers . ‘
of Kentucky to buy low-grade fertilizers. It would not recom-
ld ,0 - mend the purchase of a mixed fertilizer with a total plant food of _
gc of less than 16 percent. By the same token, it is believed that a
37000 total of 18 or 20 percent, or even more, would be more economical
mom because in this way a farmer can get the same amount of plant
gd 16 food in less tonnage and save the extra cost in freight on tillers,
frmdc Spreading and other costs incident to the niaiiufacture and hau-
2,, as dling. lt is further of the opinion that if a farmer ’s soil needs the
wtunl three primary nutrients, nitrogen. phosphorus and potassium, it
mcmg lvoul d be uneconomieal to buy a fertilizer- with less than 3 percent
ich as lllll'<>ge1i, 8 percent phosphoric acid and 4 percent potash, for the
lc SEN t same reason of cost.

my ,0 , l'¢Slllts will be loss and disappointment. The net savings to farm-
Dotasli ers annually in buying high-grade fertilizers instead of low- K
,1_C\_Hi,_ grade fertilizers would be very great. 9
USE OF COMMERCIAL FERTILIZERS
Before a farmer selects a fertilizer to use on his land, he tirst
_ should know what his land needs i11 plant food. lf he does not
volll   V know, he should consult some authority who does. The farmer .

l & tions, including the experience of other farmers. The Agronomy .
Department of the College of Agriculture of the University of  ` 2
. j Kentucky is constantly carrying out expe1·imental work with _ ,
` fertilizers. Much of this work has been published and is avail- I
able in bulletins for free distribution. Usually, the information   ,
the farmer needs for intelligent selection of l1is fertilizer is avail- .
` able for the mere asking. Some helpful publications are: Bal-  A

Q lt may be found that the soil of a particular farm is detieient {
only in, nitrogen, or in phosphorus, or in potassium. ilt would he .
poor economy to buy a fertilizer containing plant food already in I
· the soil in sutficient amounts for maximum crop production. b 3
lt is exceedingly important, therefore, for the farmer to know  
what l1is soil needs, or else he may buy something his soil. does not K
need or fail to buy what it does need. Hence, the necessity of I
. not only knowing what plant food the soil needs, but the selection ‘ 1
· of a h_igh-grade fertilizer, well balanced in the proportion of the .
plant food nutrients. 1
` EXPLANATION OF PLANT-FOOD ELEMENTS » I
Nitrogen, phosphorus and potassium are called prinuu‘}‘ _ i
plant food elements. They are the nutrients usually supplied 4 1
in connncrcial fertilizers. The percentages of these ])l'llll2ll`l·
plant nutrients are printed on the State tag as nitrogen, phos-
phoric acid and potash. Tl1e secondary or minor plant food
elements are necessary for plant growth but, with tl1e exception ‘
. of calcium and magnesium for some crops, are required by plal1iS  
in relatively small amounts and under our present knowledge ll I
A is believed they are usually present in most Kentucky soils in l
sufficient amount for proper plant growth.  
The results of many investigations indicate that certain  
nutrients perform definite functions in the growth and develolt if
1ne11t of plants. Some of these functions are;  ` 3

paring values of fertilizers of ditferent grades and should not in
· he confused with the selling price. This can not be accurately
estimated because of the many factors, some of them varialJl0, lh
which are included in it. m
The estimated value is determined by giving a value to each ee
component, which value represents the cost of that component
to the manufacturer plus an equitable share of the total cost of ,
placing the fertilizer on the market. The estimated value. <‘l'

A unit is 20 pounds, or 1 percent of a ton. If the unit value
al of each component is multiplied by the percent of the component
St · in the fertilizer and all the results are added, the estimated value
ld per ton, or index of relative value, is obtained. This valuation
to A c is used in comparing the value of samples analyzed with the
rc.  ' IllElllllli·€lCI[·llI`€1'S7 guaranties. The valuation depends upon the
an ` actual content of the fertilizer components and should not be con-

POINTS A FARMER SHOULD CONSIDER IN BUYING FERTILIZER b
1. Ascertain the need of the soil and what will supply it. —
No fertilizer will give proper results if it does not contain the ·
plant nutrients in which the soil is deticient. lf in doubt as to
the kind of fertilizer the soil needs, consult the County Agent or
the Experiment Station. ‘ .
_ 2. Be guided by the information given on the State guar-
, anty tag. °
3. Buy no fertilizer that is not registered and tagged with —
a State official tag. lf it is not tagged with a State guaranty _;
I tag, it is being sold in violation of the law and it should be
refused.  
4. High-grade fertilizers are most economical. Too many  
farmers buy on price rather than on quality. This is false (
economy. E
POINTS A DEALER SHOULD CONSIDER -  
1. Handle no fertilizer that is not registered and tagged I
with a State guaranty tag at the time of purchase.
A 2. Handle only high-grade fertilizers——fertiIizers that will F
most economically serve your customers.  
3. Buy only from reputable manufacturers who have good I
records and are complying with the fertilizer law and will assist I
you in complying with tl1e law. I4
-I. llave definitely in mind the kinds of fertilizer your 1·
trade needs and buy only fertilizers that will meet these needs. I
5. It is the p1·actice of some manufacturers to plaee tags in  
the truck or car with the shipment of fertilizer without attaeh- D
ing them to the bags, or to claim that they were put in. This often
results in confusion and failure to tag at all, as the tags may be  
misplaced or lost. The tags should be attached to the bags when `
the shipment is made. S
