[1] Pesticide and Nutrient Movement into Subsurface Tile Drains on a Silt Loam Soil in Indiana The objectives of this study were to determine field‐scale pesticide and nutrient losses to subsurface tile drains over a 3‐yr period on a low organic matter and poorly structured silt loam soil under typical agricultural management practices. A subsurface drain spacing study was instrumented to measure drain discharge rates and to collect drainflow samples continuously on a flow‐proportional basis. Two replicates of three drain … Continue reading “News Update on Loam Soil : April 21”

[1] Influence of Planting Soil Mix Characteristics on Bioretention Cell Design and Performance Municipalities are increasingly interested in using rain gardens, or bioretention cells, as a “best management practice” (BMP) for storm-water management and as a component of low impact development. However, improved technical reference materials are needed to determine the influence of planting soil mix design on the hydrologic and water quality performance of bioretention cells. This article describes three investigations undertaken to determine the influence of planting soil … Continue reading “Latest Research News on Planting Soil April-21”

The use of microbial parameters in monitoring soil pollution by heavy metals Microbial parameters appear very useful in monitoring soil pollution by heavy metals, but no single microbial parameter can be used universally. Microbial activities such as respiration, C and N mineralization, biological N2 fixation, and some soil enzymes can be measured, as can the total soil microbial biomass. [1] Limitations of soil enzymes as indicators of soil pollution Soil enzyme activities are considered to be sensitive to pollution and have … Continue reading “Latest Research on Soil Pollution: March – 2020”

Soil health and sustainability: managing the biotic component of soil quality Soil health is that the capacity of soil to function as an important living system, within ecosystem and land-use boundaries, to sustain plant and animal productivity, maintain or enhance water and air quality, and promote plant and animal health. Anthropogenic reductions in soil health, and of individual components of soil quality, are a pressing ecological concern. A conference entitled ‘Soil Health: Managing the Biological Component of Soil Quality’ was … Continue reading “Latest Research News on Soil Health: Dec – 2019”

Regions of Strong Coupling Between Soil Moisture and Precipitation Previous estimates of land-atmosphere interaction (the impact of soil moisture on precipitation) are limited by a scarcity of observational data and by the model dependence of computational estimates. To counter the second limitation, a dozen climate-modeling groups have recently performed an equivalent highly controlled numerical experiment as a part of a coordinated comparison project. this enables a multimodel estimation of the regions on Earth where precipitation is suffering from soil moisture … Continue reading “News Update on Soil Moisture Research: Dec – 2019”

Preferential flow mechanism in a water repellent sandy soil Dry water repellent soils are difficult to wet, forcing water and solutes to flow via preferential paths through the unsaturated zone. A tracer field experiment was wont to investigate the mechanism of preferential flow and transport during a water repellent sandy soil. Water and solutes are distributed by lateral flow within the, relatively wet, thin humose topsoil toward preferential flow paths below this zone. This flow within the upper layer, which … Continue reading “Latest Research on Sandy Soil: Dec – 2019”

Pedology. Soil, vegetation, environment This fourth edition includes developments between 1991 and 1994 in soil organic matter, soil consistency, the evolution of tropical soils and pollution by nitrate, and considers issues of soil classification with special relation to the FAO-UNESCO system. Four main sections deal in turn with: I: soil constituents and their origin (2 chapters); II: soil properties (5 chapters); III: soil formation and soil classification (7 chapters); and IV: applied pedology (3 chapters). [1] Hydropedology: Synergistic integration of … Continue reading “Latest Research News on Pedology Research: Sep – 2019”
