Using a simulation model as an analysis tool, the economic impact of spittlebugs in pastures of Colombia was quantified in terms of animal production. Three levels of abundance (10, 25, 50 adults/m2 ) and farm area affected (25, 50, 100%) were evaluated using data obtained in Brazil for Notozulia...
Results of preliminary experimentation with a computer based simulation model of beef production in theEastern Savannas of Colombia are reported The energetic consequences of various uses of sown pasturesare examined with reference to their long term biological feasibility The quality of grass le...
Low soil fertility is a fundamental constraint to crop production in western Kenya. Although researchers have developed many soil fertility-improving technologies, the adoption of these technologies is low due to inadequate awareness of the technologies, poor access to requisite resources and uns...
