Show of Plants Reducing The Water Fine Paper LOne of the factors crop of Utah P P and keeping it paper for the Dry Farming Congress of Reduce the Water Requirements it that statement The Doctor opened with the pounds of water to PJ from to o f Pa oui of of dry Ho quoted the who found that on poor sod it JJ of water to produce one pound While on fertile soil it required but P Utah brought out similar instance corn on unnaturally fertile piece of of dry pound of water to produce one pound When it required adding so me it to in reduced nitrate in addition to the manure loam not cultivated another experiment corn grown on sandy required pounds of When cu tiva ted it was reduced to On clay loam not cultivated reduced it to Cultivating pounds On clay soil not cultivated pounds was the requirement when cultivated this was reduced to Effect of Fertility In tho dry farming water is the limiting factor In crop By having the soil well provided with plant the plant can make more growth with a given amount of water just as one would havo to oat more soup if it were thin than if thick to supply a amount of Fertilize by putting more plant food in the soil increases production without increasing the moisture Cultivate by keeping the moisture evaporating makes ideal conditions for germs to work on the inert plant food making it available and so a larger plant Part of the value of tho summer fallow comes from the plant food made and not alone from saving up What Plowing Does He sums up as the present time the only means possessed by the farmer for controlling transpiration and making possible maximum crops with the minimum amount of water in a properly tilled soil is to keep tho soil as fertile as In the light of this the practice usually recommended for the storing of water and for the prevention of the direct evaporation of water from the soil are Deep and frequent preferably in the so that the weathering of the winter may be felt to great depths and is of the first importance in liberating plant Cultivation which has been recommended for the prevention of the direct evaporation of water is of itself an factor in setting free plant food and thus in tho amount of water required by Experiments In connection it is interesting to bring up the results of experiments conducted by Snyder of Ho for that timothy grown on poor land had a protein content of G per cent while land contained 8 on good per W that grown oXon the rich soil the plant put 36 per cent moi value into the In another experiment he fJ that corn fodder grown on poor land contained 6 J cent On the same land 9 per On clover sod 10 per in other two tons of corn fodder from-a rich soil contained food value than three tons from a poor The plantis a good deal like a when lumber is cheap L wastes As it gets expensive or hard to get he it more The same way with the as it finds the food hard to get it makes it go further consequently produces a plant with less food Rich and Poor Soil Combining these two results we get the a given amount of moisture will produce at least 30 pa cent more crop on rich soils than on poor and the crop grown on the rich soil will contain at least 45 per cent more food value than that grown on the poor In other the moisture that would produce pounds of crop on a poor soil would produce at least pounds on a rich soil and the crop raised on the rich soil would contain on an average 45 per cent more protein which would still further increase the food value of the crop grown on the rich soil to the equivalent of pounds grown on poor almost twice as much food value on the rich soil as on the poor one from the same amount of the rich soil will hold more and if there is plenty of the rich soil can grow two or three times as much crop as the poor soil and with a food value that is |
