Show LOIL Q BIG IN BEET TONNAGE what determines the difference between a good yield and a poor yield of sugar beets on a given piece of land ater after careful study and experimentation the at the utah agricultural college are convinced that the chief factor is soil fertility in a recent statement prof george B stewart emphasized the importance of a fertile seed bed and the value of barnyard manure as a factor in increasing soil fertility of all our field crops sugar beets a are re most sensitive to soil fertility says prof stewart in cultivating them one may lay down as a maxim th the statement rich soil good yield poor soil small yield to be tit fit tor for the cultivation of boots beets a seed bed ewt be moist to tho the surface and it all of the seed that germinates Is to grow there must be sufficient organic matter to hold that moisture to secure such a seed bed no factor facter Is more valuable than a liberal application ot of manure not only does this material aid in the conservation of at moisture mol aturo it Is equally valuable in insuring warmth that other essential of at good germination and growth this it ft does in two ways first it loosens heavy clay so that the suns heat can penetrate and second the decomposition of the manuri manure itself Is a constant source of heat as every farmer knows finally apart from these external benefits of manure it Is valuable because it supplies important elements of food tor for the growing plants the liquid manure is available tor for plant food as soon as it Is applied and the solid part Is rapidly rotted and made available our results here at the college have convinced us that the best beat time to ap uly manure Is in the tall fall after the crop Is harvested thus the tall fall talus rains and spring snow water carry the liquid part down into tho the soil decomposition la Is more complete also where this method is followed it if however the farmer finds find it ft impossible to apply the fertilizer in the tall fall he should apply it ft as early in tho the spring as ag possible the question ot at how thickly the manure should be applied la Is also an important one on a large farm the amount available each year may not be sufficient to enable the tanner farmer to apply it thickly over the entire acreage to be devoted to beets in that event we have found that the bast returns are to be secured from a thin application covering the entire field while a thicker application will secure a larger yield per acre a greater total tonnage of 0 beets per ton ot at manure Is secured by a thin application over a large acreage than by a heavy application ot at the same amount over a small acreage |
