Comparative tests on plowed and unplowed soil for sugar beet seed-bed preparation
by L. D. Donnen
| Full text HTML  | PDF  
Results of trials over a period of four years show that nothing is gained in the production of sugar beets by plowing the soil in seed-bed preparation provided shallow cultivation kills all the weed growth.

Fertilized legumes aid following crop of non-legumes
by John P. Conrad
| Full text HTML  | PDF  
Fertilizers containing no nitrogen may increase the growth of legumes such as bur clover, vetch, and peas, which contain relatively high amounts of nitrogen. This is possible because bacteria contained in nodules on the roots of legumes fix the free nitrogen of the air—a form unavailable to most other plants.
