Erodibility and loss of marly drived soils

EURASIAN JOURNAL OF SOIL SCIENCE (EJSS), 2015
Considering to high distribution of the marly lands in west Azerbaijan province and high sediment yield of such lands, in this research, the relation among the form and the rate of erosion on marls with their erodibility properties were studied. Therefore, marly regions of province with the special properties were recognized and the soils samples were ...

Efeito de escarificação e da erosividade de chuvas sobre algumas variáveis de valores de erosão hídrica em sistemas de manejo de um nitossolo háplico Effect of chiseling and rainfall erosivity on some characteristics of water erosion in a nitosol under distinct management systems

Revista Brasileira de Ciência do Solo, 2008
O preparo do solo altera as suas condições físicas de superfície e subsuperfície e, conseqüentemente, influencia os valores de propriedades que se relacionam com a erosão hídrica.

Tracking nitrogen losses in a greenhouse crop rotation experiment in North China using the EU-Rotate_N simulation model [PDF]

, 2010
Vegetable production in China is associated with high inputs of nitrogen, posing a risk of losses to the environment. Organic matter mineralisation is a considerable source of nitrogen (N) which is hard to quantify.

Restauração da estrutura do solo por sequências culturais implantadas em semeadura direta, e sua relação com a erosão hídrica em distintas condições físicas de superfície Restoration of the soil structure by crop sequences established in no-till, as related to water erosion in distinct surface physical conditions

Revista Brasileira de Ciência do Solo, 2010
A estrutura do solo desempenha papel de destaque no crescimento de plantas e no controle da erosão e, por conseguinte, na produção de alimentos e na conservação do solo e da água. Considerando isso, realizou-se este trabalho com o objetivo de implementar

Nutrient loss pathways from grazed grasslands and the effects of decreasing inputs: experimental results for three soil types [PDF]

Agriculture is a main contributor of diffuse emissions of N and P to the environment. For N the main loss pathways are NH3-volatilization, leaching to ground and surface water and N-2(O) emissions.

Increased CO₂ loss from vegetated drained lake tundra ecosystems due to flooding [PDF]

, 2012
Tundra ecosystems are especially sensitive to climate change, which is particularly rapid in high northern latitudes resulting in significant alterations in temperature and soil moisture.

Predicting soil carbon loss with warming

Nature, 2018
Crowther et al. reported that the best predictor of surface soil carbon (top 10 cm) losses in response to warming is the size of the surface carbon stock in the soil (that is, carbon stocks in plots that have not been warmed), finding that soils that are high in soil carbon also lose more carbon under warming conditions.

Nitrogen and Phosphorous Loss as Affected by Plough Direction in Rainfed Wheat Land of a Semi- Arid Region

علوم آب و خاک, 2020
Sloping farmlands are the major sources of soil, water and nutrient losses in arid and semi-arid regions. Information about the impacts of different tillage practices on soil erosion, nutrient loss and crop nutrient uptake on the sloping farmland of semi-

Impacts of climate change on erosion of a watershed: Simulation of scenarios

Revista Ambiente & Água, 2011
Climate change set to occur in the coming years should have severe effects on erosion process, as factors leading to intensification of the peaks of rainfall and increasing temperature on the entire planet. Several studies have been performed to estimate
