1. EMISSION OF NITROUS OXIDE AND CARBON DIOXIDE AFTER APPLICATION OF PIG SLURRY AND CATTLE DEJECTIONS IN AN HAPLUDALF / EMISSÃO DE ÓXIDO NITROSO E DIÓXIDO DE CARBONO APÓS APLICAÇÃO DE DEJETOS DE SUÍNOS E BOVINOS EM UM ARGISSOLO
Emission of greenhouse effect gases due to the agricultural use of the dejections of animals as fertilizers, as well as the mineralization of the carbon of those materials in the soil healthy aspects are still relatively a little studied in Brazil. This work was accomplished to evaluate: 1) the annual emission of nitrous oxide with the use, in the corn, of m

4. ADUBAÃÃO COM NITROGÃNIO, FÃSFORO E POTÃSSIO PARA EXPERIMENTOS COM CAFEEIRO EM VASOS. / Fertilization of coffee plants in vase with nitrogen, phosphorus and potassium
This work aimed at to adentify the appropriate fertilizarion for coffee plants in its initial formation phase using vases. The initial amount of phosphorus in the soil was 100 mg dm3 and 400 mg dm3 for nitrogen and potassium. The experiment was perfomed at the Cofee Section of th e Agricultura Departament from the Federal Iniversity of Lavras, from june to D
