Show HOW TO RESTORE FERTILITY OF SOIL European Methods Compared with Those in Use in the United States. HOW to restore nud maintain tbo productivity of the soil Is the most important phase of the conservation problem. In many of our older communities soli fortuity has been reduced below tho point of profitable production. Nation wido effort at tbo present timo, 'through federal and state agency, is 'directed townrd tho restoration of fertility fer-tility in theso localities. In tho older I countries of Europe, where farming bos been followed for many centuries, the problem of satisfactory yields of furtn crons hnH been solved. Tim rur. rlculturo of Germany is similar to that of tho United States, but tbo yield per acre of wheat In Germany is ruoro than twice that in the United States, the yield of rye nearly twico as large, the yield of barloy nenrly a third larger lar-ger and the yield of oats tnoro than ono-thlrd larger. ' The proportionate area of cerealB grown In Germany is about ono-flftu less than In the United States, whllo tho proportionate area of hay nnd for-ago for-ago crops Is one-half greater. In addition addi-tion to that, tho porccntngo of the total nroa which Is planted to root crops Is enormously greater In Gormany than lmtho United States. Theso root crops consist largely of potatoes and sugar beats, and tbo best German authorities authori-ties estlmato that at least one-third of tbo products of tbo area of theso two crops Is available for stock feed. They also estimate that one-third of the products of the area devoted to cereals Is devoted to tho feeding of domestic animals. Germany theroforo devotes very much more of her soil to tho production pro-duction of feed for live stock than does tho United States. On tho same area of farm land the Gorman fnrmor maintains on the aver-ago aver-ago from 80 to 78 per cent more live ' stock than does tho American farmer. Tho manure from these animals Is also ; better cared for In all European coun- J tries than it Is In this country.

German Ger-man farmers not only conserve their own nntural resources, but they draw on othor parts of tho world to maintain main-tain tho fertility of their lands. America Amer-ica baa been mining her soil and shipping ship-ping tho products to Europe In addition addi-tion to the sources of fertility above given, Germany uses annually on hor soil 050,000 tones of nltrnto of soda, 275,000 tons of sulphate of ammonia, 1,200,000 tons of superphosphato nnd 1,400.000 tons of basic Blng In addition to largo amounts of potash salts. 1 o |
