The Effect of Soil Coverings on Soil Respiration in Sandy Soil

open access: yesActa Agraria Debreceniensis, 2003
The purpose of our experiments is to study effect of different soil coverings (porous black polyethylene called agroszövet and black polyethylene) on CO2 production in sandy soil. The CO2 production was measured in our laboratory according to Witkamp (1966 cit. Szegi, 1979), after 5 days’ incubation period. Samples were taken off four times (March, May,

Quantification of C and N stocks in grassland topsoils in a Dutch region dominated by dairy farming

open access: yes, 2011
Estimates on soil organic carbon (SOC) and nitrogen (N) stocks in soils cannot be directly calculated from routine soil analyses, since these often lack measurements on soil bulk density (Bd).

Effect of Different Soil Textures and Infestation Levels on Reproduction and Damage Potential of Meloidogyne incognita on Sugarbeet [PDF]

open access: yesJournal of Plant Protection and Pathology
This study was conducted to evaluate the effect of five soil textures (sandy, sandy loamy, loamy sandy, loamy, and loamy clay) and five inoculum levels (1250, 2500, 5000, 10000, and 20000 J2/pot) on the reproduction and damage potential of Meloidogyne ...

Differential Transport of Atrazine and Glyphosate in Undisturbed Sandy Soil Column

open access: yes, 2010
With increasing awareness and concern for environmental quality, it is important to study the fate of pesticides in the subsurface. Laboratory studies were conducted to determine the behavior of atrazine and glyphosate within the root zone of an ...

Soil heavy metal contamination and acid deposition: experimental approach on two forest soils in Hunan, Southern China [PDF]

open access: yes, 2005
In 1985, a tailing dam collapsed in Hunan province (southern China) leading to soil contamination by heavy metals from the tailings waste. Moreover, acid deposition becomes more and more serious in this area. In this context, two forest soils (a red soil

Changes in soil bacterial community characteristics in patches of different vegetation types under different stages of restoration in the desert of northern China

open access: yesEcology and Evolution
In desert areas, the process of mobile sandy land changing to semi‐fixed sandy land and eventually to fixed sandy land after undergoing vegetation restoration is inevitable.

P-equilibrium fertilization in an intensive dairy farming system: effects on soil-P status, crop yield and P leaching

open access: yes, 2010
In the coming decade, European dairy farms are obliged to realize a balance between phosphor (P) inputs to their farmland (in inorganic fertilizers and manure) and outputs (in crop products), the so-called P-equilibrium fertilization.

Superhydrophobic surfaces: a model approach to predict contact angle and surface energy of soil particles [PDF]

open access: yes, 2009
Wettability of soil affects a wide variety of processes including infiltration, preferential flow and surface runoff. The problem of determining contact angles and surface energy of powders, such as soil particles, remains unsolved.
