Continuous crop expansion has led to a growing demand for phosphate fertilizers. A sound
knowledge of the dynamics of phosphorus, and its interaction with iron oxides and organic …

Crop production in the Brazilian Cerrado is limited by soil phosphorus (P) supply without
large inputs of inorganic P fertilizer, which may become more costly and scarce in the future …

Growing cover crops to recycle soil nutrients in no-tillage systems provide nutrients
accumulation in more labile forms in the soil surface reducing the demand for fertilizers. This …

Crop rotation, cover crops introduction and no tillage adoption have improved tropical
agriculture sustainability through improvements on soil conservation and water use …

The insertion of the animal component into the crop production system can alter the nutrient
dynamics and, consequently, the soil fertility status over time. This change occurs differently …

Soil organic carbon (SOC) is the main terrestrial carbon reservoir. The spatial distribution of
SOC is mainly regulated by environmental factors and anthropogenic activity. Historically …

The objective of this work was to evaluate the effect of biochar made from Eucalyptus on soil
fertility, and on the yield and development of upland rice. The experiment was performed …

Biophysical and socio-economic improvements of farming systems have been obtained with
integrated crop–livestock systems (ICLS). Grazing in ICLS under no-tillage conditions may …

Environmental monitoring of small, rural watersheds was one of the components of the
Natural Resources Management and Rural Poverty Alleviation Program (RS-Rural) in …

Phosphorus (P) is a critical nutrient for primary production in terrestrial and aquatic
ecosystems. As P mineral reserves are finite and non-renewable, there is an increasing …
