A weighing lysimeter was designed for and used in field areas not equipped to accommodate instrumentation requiring a power supply or constant maintenance for accurate operation. A hanging crane scale, which held the lysimeter box, remained responsive and accurate throughout a season of field installation. The only maintenance requirement was that of periodically leveling the suspended box by adjusting turnbuckles installed at each corner. Seasonal water loss data were obtained from lysimeters planted with cotton (Gossypium hirsutum L.) and soybeans [Glycine max (L.) Merr.]. These data are comparable to other lysimeter water use data for these two crops obtained at other locations.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
