Última Carbon, light organic matter and oxidizable organic fractions in alley cropping system PFB - Pesquisa Florestal Brasileira Guareschi, Roni Fernandes; Pereira, Marcos Gervasio. The objective of this study was to evaluate the levels of total organic carbon (TOC) of the soil, light organic matter (LOM) in water and oxidizable fractions of organic carbon in a cultivated area of maize in the alleys Flemingia macrophylla under different managements of their shoot. The study area is located in “Agroecological Fazendinha in Seropédica city, Rio de Janeiro, Brazil. The experimental design was randomized blocks with three treatments and eight replications, consisting of the following treatments: control (corn cultivation with no alleys); cultivation of maize in alley cropping with pruning to 0,6 m high and growing maize in alley cropping system without pruning. In each area composite samples were collected at 0-5 cm. The presence of...

Ano: 2013 URL: http://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/450 Adsorption of P and forms of iron in no-tillage areas in the ‘Cerrado’ biome Agronomy Pereira, Marcos Gervasio; Guareschi, Roni Fernandes; Perin, Adriano. The objective of this study was to evaluate the forms of iron extracted as sodium dithionite-citrate-bicarbonate (Fed), acid ammonium oxalate (Feo) and sodium pyrophosphate (Fep) and the relationship between these variables and the total organic carbon content and maximum adsorption capacity of P (MACP). The areas selected for this study had been using a no-tillage system (NTS) for varying periods of time: 3 years (NTS3), 15 years (NTS15) and 20 years (NTS20). These areas were compared with an area of native ‘Cerrado’ (CE) and a pasture area planted with Brachiaria decumbens (PA). The soil of the areas studied was classified as dystrophic oxisol. In each area, samples were collected at 0–5 cm and 5–10 cm. A correlation was observed between the C content...
