Abstract

The data presented in this paper show the lack of agreement between the barley producing power of soils and the yield and condition of citrus on such soils at the time the samples were taken. Moreover, it cannot be concluded that the amount of nitrogen previously added to a soil is an accurate measure of its barley producing power. The addition of phosphoric acid or potash to the soils studied has not shown any added advantages for the growth of barley or of citrus.
