The Connecticut Agricultural Station Reports 
for 1906, 1905, 1904 on the 
Relative Cheapness of High and Low Priced Fertilizers. 
The official reports of the Connecticut Experiment Station for 1906, 1905 and 1904 
contain the analyses of over six hundred samples of brands of mixed fertilizers (samples taken 
in the market). In these reports of analyses the MAPES MANURES are given the highest 
valuation of all and on the ordinary basis of figuring "'valuations;*’ no benefit is received by 
the MAPES MANURES for the superior and more costly forms of Potash, as Nitrate of 
Potash and Carbonate of Potash (eight cents instead of five cents per lb.), nor of the superior 
forms in Peruvian Guano, Pure Animal Bone Flour, of Nitrogen, Ammonia, Phosphoric Acid, 
Potash, etc.

“As a rule, fertilizers which sell at a low price are really the most costly if we regard the amount of 'plant food 
in them. 
“Some brands of fertilizers sold in Connecticut by reputable manufacturers,and freely bought by some farmers, 
supply scarcely more than one-third of the plant food which can be bought for the same amount of money in other 
brands which are sold in the same places. That is, in buying these brands, the farmer is simply throwing away 
two-thirds of his purchase money.'”

“The Connecticut Agricultural State Report again confirms what we have so often urged—that the cheaper the 
price per ton of a commercicd fertilizer, the higher the cost per pound of the actual Nitrogen, Potash and Phosphoric Acid it 
contains. Accordingly, it is not surprising that Dr. Jenkins contends some farmers are not getting the benefit from 
fertilizers that they might, because they go for cheapness instead of quality P 
“ Exactly 600 commercial fertilizers and waste products have been analyzed and tabulated.” 
"VALUATION” OF FERTILIZERS 
They Fail to Determine the Quality of Goods. Established Reputation the Main Security to the Purchaser. 
Extracts from Annual Report of the Connecticut Agricultural Experiment Station, 
Prof. S. W. Johnson, Director, for year 1895. Issued December, 1895. 
“ The valuations^ , it must be remembered, are based on the assumption that the nitrogen, phosphoric acid, and 
potash in each fertilizer are readily available to farm crops. Chemical examination can show pretty conclusively 
whether this is true in respect to potash. There is less certainty regarding phosphoric acid, while chemical examina¬ 
tion, as it is usually made, gives little or no clue as to the availability of the organic nitrogen of mixed goods.” 
“ While various inferior or agriculturally worthless forms of nitrogen are in the market, the main security of 
purchasers of mixed fertilizers is in dealing with firms which have an established reputation , and in avoiding ‘cheap’ 
goods offered by irresponsible parties.”—Page 39. 
From the Rural New-Yorker, March 28 , 1903 : 
HIGH GRADE FERTILIZERS —The Rural New-Yorker has always made it a point to urge farmers 
to buy the highest grade of fertilizers they can obtain. The Mapes fertilizers have for years been known as the 
standard for high-grade goods. They are not simple mixtures of three or four chemicals, but often contain six or 
eight different ingredients—often supplying four different forms of nitrogen and several each of potash and phos¬ 
phoric acid. Do these elaborate mixtures pay? The best answer is given by the great army of farmers and fruit 
growers who continue to use the Mapes goods year after year. The chemists “valuation” of a fertilizer does not 
always show its true value. For example, the last report of the Connecticut Station gives the valuation of two Mapes 
brands, and then states that since nitrate of potash and carbonate of potash are used the real valuation should be about 
$3.50 per ton above that given on the ordinary basis of figuring.
