1. Methane emission induced by short-chain organic acids in lowland soil
ABSTRACT Methane (CH4) is the second major greenhouse gas after CO2, exerting a significant influence on the climate and the chemistry of the atmosphere. In lowland soil, acetate and H2/CO2 are the most important precursors of CH4 and formed from organic matter fermentation in an anaerobic environment, giving rise to short-chain organic acids (ethanoic, prop

2. Calcium partially relieves the deleterius effects of hypoxia on a maize cultivar selected for waterlogging tolerance.
Low soil oxygen concentrations due to waterlogging or transient flooding severely reduce maize production. However, genotypes with tolerance or even resistance to hypoxia develop morphological and biochemical adaptation mechanisms which may prove to be useful criteria for the selection and breeding of new improved genotypes. The objective of this work was to

3. Efectividad de fertilizantes fosfatados en arroz.
Bajos niveles de fosforo (P) disponible en los suelos son una limitante comun en extensas areas arroceras del NE de Argentina y Sur del Brasil. Se realizaron experiencias en arroz (Oryza sativa, L.) con el objetivo de comparar los efectos directos y residuales de las aplicaciones de dos fuentes de P sobre el rendimiento de granos de arroz, absorcion de P y d
