Bulletin for the Massachusetts agricultural experiment station: phosphates in Massachusetts agriculture
Description:
This bulletin is meant to show that phosphoric acid is not relatively deficient in Massachusetts soils, and that under the systems of agriculture common in the State there is no reason to believe that it is generally becoming more so. The general results of the two series of experiments comparing different phosphates, one extending over twelve and the other over eighteen years, are presented. The section 'importance, selection and use' is written by WM. P. Brooks.
