Show Answer by Prof. R. S. Northrop. The condition described in Mr. Bunker's letter evidently calls for a leguminous cover crop. I believe that if he would try cow peas or soy beans for two or three years he would find that they would develop a very heavy crop for soiling purposes. While wc use vetch here, the whip-oorwill whip-oorwill variety of cow peas or the common stock of soy beans would, in a region where a long dry climate prcvai's, p'oducc a much greater amount of green manure. These crops have been tried for a season ' or so at St. George but, so far as my knowledge goes, did not succeed in developing to any great extent, due to the fact that the specific bacteria bac-teria which aid them in their development develop-ment were lacking in the soil. I believe, that by repeated sowings on same land for two or three years or possib'y by securing a start of the nitrogen gathering bacteria from the Department of Agriculture the bed of results wou'd be obtained. T would suggest that they be planted plant-ed in rows between rows of grapes for the first two or three years, or in a special garden plot and cultivated cultivat-ed carefully after which any land could be innoculatcd with the soil . from the part where they have been grown. Seed can be secured from any of the larger eastern seedsmen or could .be secured for cu by anv of the Salt Lake seed houses. |
