Short-term impacts of high levels of nitrogen fertilization on soil carbon dynamics in a tropical pasture
(2019-03-01)
Bermudagrass (Cynodon spp.) is widely recognized by its ability to respond positively to nitrogen (N) fertilization. Nitrogen often promotes shoot and root growth and, consequently, increase carbon (C) inputs into the soil ...
Carbon and nitrogen stock and fluxes in coastal Atlantic Forest of southeast Brazil: potential impacts of climate change on biogeochemical functioning
(INT INST ECOLOGYSAO CARLOS, 2012)
The Atlantic Forest is one of the most important biomes of Brazil. Originally covering approximately 1.5 million of km(2), today this area has been reduced to 12% of its original size. Climate changes may alter the structure ...
Cover crops in the Southeastern region of Buenos Aires, Argentina: effects on organic matter physical fractions and nutrient availability
(Springer Verlag, 2018-06)
In the Southeastern region of Buenos Aires province, soybean monoculture has led to a decline in soil organic matter (SOM) levels in soil, mostly the labile fractions. The reduction of SOM has a negative impact on the soil ...
Stover quality and soil organic carbon in long-term nitrogen-fertilized maize
(Amer Soc Agronomy, 2014-09)
Nitrogen fertilization often increases maize (Zea mays L.) grain yield but reduces the C/N ratio of stover returned to the soil, which may affect the soil organic carbon (SOC) balance. This study evaluated the long-term ...
Flujos de carbono y nitrógeno bajo distintos sistemas de labranza en la región semiárida pampeana
(Facultad de Agronomía, Universidad de Buenos Aires, 2010-03)
Los contenidos de carbono y nitrógeno orgánicos del suelo están relacionados con su capacidad productiva. Esta relación es esperable que sea más estrecha en suelos de zonas áridas y semiáridas. La cantidad de carbono que ...
Carbon and nitrogen cycling in a tropical Brazilian soil cropped with sugarcane and irrigated with wastewater
(ELSEVIER SCIENCE BV, 2010)
Carbon (C) and nitrogen (N) dynamics in agro-systems can be altered as a consequence of treated sewage effluent (TSE) irrigation. The present study evaluated the effects of TSE irrigation over 16 months on N concentrations ...
Microorganisms in sewage sludge added to an extreme alkaline saline soil affect carbon and nitrogen dynamics
(2012-11-27)
There are plans to vegetate soil of the former lake Texcoco and use wastewater sludge to provide nutrients.
However, the Texcoco soil is N depleted, so the amount of N available to the vegetation might be
limited and the ...
