Soil compaction in a Cambisol under grassland in Estonia [PDF]

Zemdirbyste-Agriculture, 2013
In soil compaction research, more attention has been given to arable land than to grasslands. Our objective was to investigate the effect of agricultural machinery on the physical and mechanical properties of soil under intensively cut lucerne (Medicago sativa L.).

Changes in the soil organic carbon balance on China’s cropland during the last two decades of the 20th century [PDF]

, 2017
Agro-ecosystems play an important role in regulating global changes caused by greenhouse gas emissions. Restoration of soil organic carbon (SOC) in agricultural soils can not only improve soil quality but also influence climate change and agronomic ...

Microbial biomass-C determined using CaCl2 and K2SO4 as extraction reagents

Plant, Soil and Environment, 2005
Microbial biomass-C [MBC] was determined by re-hydration [RHD] technique using two very similar salt solutions in dissociation potency (0.5 mol/l K2SO4 [MBC-K] and 0.01 mol/l CaCl2 [MBC-Ca]) in forest, grassland, arable Cambisols [Inceptisols] and ...

Field Studies on the Influence of High‐Voltage Direct Transmission Underground Cables on Soils Along the SuedLink Route in Southwest Germany

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
