Soil carbon transformation in long-term field experiments with different fertilization treatments
Plant, Soil and Environment, 2018 Soil carbon transformation was observed in long-term stationary field experiments (longer than 20 years) at two sites with different soil-climatic conditions (Luvisol, Chernozem).

Interactions between metals and soil organic matter in various particle size fractions of soil contaminated with waste water [PDF]
, 2009 Only scarce field studies concern the consequences of natural soil organic matter (SOM) and metal interactions on SOM dynamics in soils. We investigated the interactions of four metals (Pb, Zn, Cu and Cd) with the SOM associated to five different size ...

The organic matter of the different ages fallow Luvisols
IOP Conference Series: Earth and Environmental Science, 2018 © Published under licence by IOP Publishing Ltd. The study of the change in the humus state of the fallow Luvisols of different ages under the influence of weeds and meadow vegetation was carried out in dynamics (after 5 years). It is shown that both under weedy and meadow vegetation there is a statistically significant accumulation of organic matter ...

Impact study on the application of vinasse to cambisol and vertic luvisol in Ethiopia [PDF]
, 2013 To study an impact on the application of vinasse to Cambisol and vertic Luvisol in Ethiopia, we used HP1 an hydrogeochemical models to assess the medium-term risks of the use of that agricultural practice by a Sugar Factory.

Microbial characteristics, carbon and nitrogen content in cambisols and luvisols [PDF]
Plant, Soil and Environment, 2004 Tested soils (1991-2002) were defined by chemical, textural and microbial characteristics. From the tests which describe cambisols, the following parameters have to be stressed. The higher level of Corg (1.20-1.76%), which resulted in quite high microbial biomass carbon content (396-625 µg/g dry soil), high control respiration (0.45-0.80 mg CO2/h/100 g

Potential primary production of unirrigated land in the Sahel [PDF]
, 2007 According to recent insight, the toxicity of metals in soils is better related to the free metal ion (FMI) activity in the soil solution than to the total metal concentration in soil.

Journal of Plant Nutrition and Soil Science, EarlyView.During regular operation of the SuedLink at a load ≤75 %, the average increase in temperature in the plowing horizon is expected to be less than 1.6°C in the soils along the route in Southwest Germany. ABSTRACT Background The SuedLink was planned as a high‐voltage direct‐current underground cable route. The construction itself is a massive intervention

Land use affects the soil C sequestration in alpine environment, NE Italy [PDF]
, 2017 Soil carbon sequestration is strongly affected by soil properties, climate, and anthropogenic activities. Assessing these drivers is key to understanding the effect of land use on soil organic matter stabilization.
