Show A FEW SIMI'Lli FACTS. The farmer In these tiaye must be umetbiiiir ol n ecieiitist; not that he must burn the inldiiliht oil over eciea-titlc eciea-titlc books and lecturer, nor that he iiiuU tnke a scientific course. If lis is wise, however, he sill get clearly In iiiiiui a few simple fuels which sclen-tlllc sclen-tlllc Investigation has fully; estnbl'ahid, mid tho object of the present arrlclu U to group n few o( these together and put them In such (.Imps that tho farmer can get a flun grasp on them and keep that grasp continually, meditating by daytime as ho turns the furrow as to i heir bearing upon his busliisss. Our lenders all know bv ililn Hint. wm. .wxuv.a t.ll n.ll11 I'J HUB ilUIC that nitrogen in soinu ol its combinations combina-tions is essential lo plant nnd animal life. You cannot grow nn ounce of muscle or an ouuco of healthy bone without nitrogen, and this nitrogen must get to the animal throush the plunt nnd to tho plant through (he sail and to the soil from tho nlr. Nitro. gm lu one sense is tho cheapest thing in the world K curly four-fifths of the air is composed of what Is called free nitrogen, mid yet neither plant nor animal ani-mal cm avail itself of jt except its na lure has been entirely ghanged, Ills so cheap that it Is worthless, and sometimes some-times we think the Creator mixed It with the oxygen to kcep this whole 1 n .I i. ii ".ijLJgrAt i .....-woild .....-woild from bolng b)wn to piece the Ilrst time some farmer strike a match. The ntlrogen which" we have In the roll lis been derived front the air through iho lrufryi of Jegumlnou plant, whether grasses, trees, Weeds, or the lower forms of plant life. Th second largest family of plant wo har Is the Lcgumlnosso, and It Is their bub nest to draw from tho nlr enough nitrogen nit-rogen to keep plant and animal life In existence. Thl is done Cj rough the tubercle, or, rather, the microscopic In. habitants of the tubercle which are found on the roots of these plants, How, thcr, may the fanner avail himself of these simple fscl In which we have condensed the teachlnir of wbolo volumes ami long and patient years of Investigation on the part of scientific men ? First, let hi in establish a rotation ol crops in which a large place is given lo tlieso leguminous plants,' the clovers, where he can grow tUem, and cowpeai, soy bean, 'and alfalfa al-falfa w hero he can not. If he harvest bis nllrogKii by plowing up a crop of clover after It has produced seed, be has dono two things : First, secured a supply sup-ply ef nitrogen for th use of plantsr second, ho has stored the soil with humus In nhich nitrogen i mainly held. No farm can run dawn If it I kept lu good physical condition and well supplied with nitrogen. Ho fsrro, however well supplied with nitrogen, can do it best unless it is kept in good physical condition, that Is, well farmed; In other wotdn, tho soil must bcrin such shape that the plant roots can utilise Its fertility Ko farm, however good Its physical condition may be, can ever bo permanently profitable unlet the supply both of humus and of nitrogen Is maintained. II the supply oriiumui is exhausted by continuous cropping without the addition of vegetabte matter mat-ter It will become pasty in a wet time, will become compacted in a dry lime, and hence plants cannot avail themselves them-selves of its fertility. Another point which we have touched upon elsewhero Is that the farmer should as far as possible keep his lsnd full ol llyo plant roots to tako up the nitrates as fast as Ihey are formed by mlcroblc action from the nitrogen anj humus In tho soil. Natu-e- I always attempting to do this. It throws up weeds in the stnbblo rfs soon a the crop is removed unless it has been sowed down to tho tame graBes. It slwnys keeps something growing. If tho farmer has exhausted the fertility, It grows whatever it can even If It be nothing but broom sedge. It start tree and brush, anything that will grow, and, given timo enough, it brink back tho lost fertility. Let the farmer take note of nature's methods. If shattered oat, wheat or rye prfng up after harvest, let them grow. Thoy art living to retain the fertility of the soli. Nor should the farmer ovsr frgct that the deep, rich, black soil the world over aro largely those whera the soil freezes In the winter, thu arr.stiug the development of nitrate nnd preventing the waste of fertility SValUce' Farmer, |
