Economic Feasibility of Crop‐Livestock Integration System in Brazil

open access: yesAgribusiness, Volume 41, Issue 4, Page 1028-1038, Autumn 2025.
ABSTRACT We investigate the economic feasibility of the Brazilian crop‐livestock integration system. Under this system, the Brazilian farmer can produce soybeans, corn, and graze for cattle on the same land during one crop year. This technology can substantially increase agricultural production in the country.

Lake Mahega: a mesothermic, sulphato-chloride lake in western Uganda

open access: yes, 1972
In May, 1971, Lake Mahega had pronounced mesothermy (40.W C at one metre). Solar heating of a bloom of baeteria and the blue-green alga, Synechococcus bacillaris Butch., probably caused the high temperature. A total ionic concentration gradient increasing from 192,600 mg 1itre-1 at the surface to 415,200 mg•litre- 1 at three metres stabilized the ...
