2. Dry matter production response of coastcross (cynodon dactylon) (L.) pears) to sources and rates of nitrogen.
Dry matter production of a coastcross pasture grown on a dark red latosol (hapludox), in Sao Carlos. Sao Paulo State, Brazil, under tropical altitude climate, was evaluated. The goal was to verify the efficientcy of N rates as urea and ammonium nitrate: 0,25,50,100 and 200kg ha per cutting, in five periods. Both sources were equally efficient. The mean N rat

3. AGRICULTURE OF PRECISION: MANAGEMENT OF THE FERTILITY WITH APPLICATION OF THE VARIED RATE OF FERTILIZERS AND ITS RELATION WITH CROP YIELDS / AGRICULTURA DE PRECISÃO: MANEJO DA FERTILIDADE COM APLICAÇÃO A TAXA VARIADA DE FERTILIZANTES E SUA RELAÇÃO COM A PRODUTIVIDADE DE CULTURAS
The agriculture of precision has been an important tool for the characterization of the spatial variability of soil attributes and crops. Thus, there is many options to elaborate thematic digital maps that can improve the soil and crop management. In this work, two croplands that has been managed with precision agriculture during several years were selected.
