The Comparative Effects of Calcium Carbonate and of Calcium Silicate on the Yield of Sudan Grass Grown in a Ferruginous Latosol and a Hydrol Humic Latosol
Get PDFSeveral current field experiments in the Hawaiian sugar industry have shown that liming has increased both yield of sugar and phosphorus uptake by the plant. This interest led to the initiation of this study, which had as its objective a comparative study of the effects of application of calcium silicate and calcium carbonate on the growth of plants and on the availability of phosphorus when applied to a soil having aluminum oxides in a fairly good state of crystallinity against a soil in which aluminum exists in a highly hydrated colloidal oxide system

Get PDFA preliminary investigation of four soil series of the Pin Gin family
of krasnozem soils has confirmed the results of field observation on their history
and has pointed to the diverse nature of their origins and weathering processes.
The weathering pattern and origin can account for differences in their fertility in
the virgin state
