Soil Property, Rather than Climate, Controls Subsoil Carbon Turnover Time in Forest Ecosystems across China
C turnover time SOC stock soil property climate
2023/11/22
Subsoil (0.2–1 m) organic carbon (C) accounts for the majority of soil organic carbon (SOC), and SOC turnover time (τ, year) is an important index of soil C stability and sequestration capacity. Howev...

microtremors H/V technique sire response subsoil geological structure
2015/9/28
Nakamuras technique, or the H/V spectral ratio method, has been applied to microtremor measurements carried out in the urban area of Catania (Eastern Sicily) to obtain information on the geological st...

nitrates fertilisation irrigation
2015/3/1
This paper presents the results of the nitrates movement monitoring under the conditions of field

Retardation of Nitrogen Leaching by the NO3– Adsorption in the Subsoil in a Watershed of Old Japanese Cedar and Cypress Stands
anion adsorption column experiment forest cutting subsoils volcanic ash soils
2009/8/25
Volcanic ash soils contain appreciable quantities of anion adsorption capacity (AEC) due to the variable charge, and they adsorb anions by non-specific adsorption. To study the effect of this characte...
INFLUENCE OF BROWN COALS, SLUDGE AND THEIR MIXTURES AND FYM ON THE CONTENT OF CADMIUM AND LEAD IN SUBSOIL AND ITALIAN RYEGRASS
cadmium lead brown coal sludge mixture Italian ryegrass
2009/3/31
The pot experiment was carried out over 1998-2000 which aimed at defining the effect of brown coals, sludge as well as their mixtures and farmyard manure (FYM) on the content of cadmium and lead in su...
Cotton Yield Response and Economic Implications to In-Row Subsoil Tillage and Sprinkler Irrigation
Cotton Yield Economic Implications In-Row Subsoil Tillage Sprinkler Irrigation
2008/12/15
Deep tillage at a 45° angle has been a recommended practice since the mid-1970s on most Mississippi Delta cotton soils. This practice disrupts hard pans and allows deeper wetting of the soil profile w...
Effect of subsoil compaction on the hydraulic processes in landscapes
soil density preferential flow subsoil compaction
2008/12/2
In Grey clayey loamy agricultural soils the horizontal and vertical variability of soil density is the dominant factor in the formation of preferential water filtration flow paths. These paths are pre...
Phosphorus extractability in surface soil samples as affected by mixing with subsoil
phosphorus sampling soil horizons sorption isotherms
2010/8/16
Samples taken from the plow layer (Ap horizon)and subsoil (B horizon)of six cultivated soil profiles were analyzed as original samples and as mixtures containing 25% or 50% material from the B horizon...
