The Waterbury Democrat., 1942-08-17

representatives made list of fer tilizer grades considered necessary for each state in the region. The following day the group met with representatives of the fertilizer trade and presented the list for adoption. The final list approved in Boston is now in the hands of the OPA and will soon be released to the public. The number of grades permitted will probably not exceed 12 or IA, in contras: to some 65 sold in Connecticut last year. Most of the regular grades will come out with less nitrogen but with no change in phosphorus or potash. For example, a 5-10-10 grade (referring to the percent of nitrogen, phos- phorus and potash respectively will become 4-10-10.
 Plenty Of Phosphorus And Potash
 By applying the usual amount of fertilizer, the farmer will be keep ing up the phosphorus and potash content of his soil and will at the same time be saving nitrogen for war use. Further, by taking special pains to conserve manure and crop residues and by making greater use of legumes, he may overcome to a considerable extent the nitrogen de- ficlency of the fertilizer.
 To reduce freight tonnage and la- bor requirements, low analysis fer tilizers will not be obtainable, the minimum being 20 units. An ex- ception is made only in fertilizer for tobacco, for which the custo- mary 6-3-6 grade will likely be re- tained. Although most of the in- organic nitrogen will go into mix lures, some will be available for side dressings of vegetables and other forced" crops.
 Mixed goods, Dr. Lunt points out, are made up mostly of inorganic materials. The only inorganic nitro gen carriers which will be available in quantity the coming year are sulfate of ammonia and nitrate of soda. No cut is expected in the former, which is obtained as by- product from coke ovens or syn thesized from free nitrogen in the air, but there may be some reduc- tion in the latter because it is shipped from Chile. Urea. solution nitrogen, cyanamide and similar materials will disappear from the fertilizer market because of their use in the manufacture of muni- tons.
 Available Organic Nitrogens
 No materials containing inorganic nitrogen are to be used on fall- sown grains in the states to the south and next to Connecticut, 1t being the concensus of opinion that their omission will have very little effect on the crop. Organic sources of nitrogen are more abundant than ever, but at the moment are con- Sidered too bulky and too expensive for use in fertilizer formulas intend- ed for average farm, garden or or- chard use. A few such mixtures will probably be on the market, and these will be the only complete fer tilizers available, for lawns, flowers and other ornamental plantings. Nitrogenous organizes can be pur- chased alone in unlimited quanti- ties. and these materials (cotton- seed meal, castor pomace, fish scarp, tankage. activated sewer sludge, etc) will he available to the home owner and landscape gardener Dr. Lunt foreSeeS no necessity for rationing fertilizer to individuals, as in gasoline. provided dealers and farmers alike do their part to make the available supply go as far as possible in the very important task of producing food for the nation.
