At present, spatially very detailed data sets can be obtained about soil, landscape and crop variability. However, there is a need to select independent key properties to identify management classes needed for precise land management. In a previous study performed in the European loess belt, topsoil pH, apparent electrical conductivity (ECa) and elevation were identified as key properties. In this study we enlarged the number of soil properties by including gamma ray measurements and employed a similar methodology to a field in the sand belt of northern Europe.

This article describes the WEPS management submodel component which simulates the effects of typical cropping management practices, such as tillage, planting, harvesting, irrigation, or residue burning, at an operational level. Such management practices can affect the surface conditions, which in turn affect wind erosion potential. A variety of land management operations is simulated by identifying the primary physical processes involved and representing each individual operation as a sequenced set of those processes.

Fine particulates less than 2.5 μm (PM2.5) or 10 μm (PM10) are often emitted from river bank or other alluvial lands to the atmosphere during dry and windy seasons worldwide, which contribute to land degradation and poor air quality. Investigation of PM2.5 and PM10 emission potential could contribute to the development of mitigation strategy and better land management practices. In the lowprecipitation zone (

The excessive use of plant protection products (PPPs) has given rise to issues of public and environmental health because of their toxicity. Reducing the use of toxic PPPs and replacing them with products that are less toxic for human health and the environment have become socially, environmentally and economically indispensable.

Huffman, T., Coote, D. R. and Green, M. 2012. Twenty-five years of changes in soil cover on Canadian Chernozemic (Mollisol) soils, and the impact on the risk of soil degradation. Can. J. Soil Sci. 92: 471–479. Agricultural soils that are covered by vegetation or crop residue are less susceptible to degradation by wind and water erosion, organic matter depletion, structural degradation and declining fertility.

Biodiversity conservation is gradually shifting its dependency on public protected areas to take a more holistic ecosystem and landscape approach that includes private lands in addition to public lands. However, effective practice of biodiversity conservation on private land also depends on landowners’ attitude and their willingness to participate and cooperate. This study focuses on Poland where conservation on private land is a relatively new concept but it is slowly gaining recognition, especially after its accession into the European Union.

Due to a rapidly expanding human population in Florida, fire management has become hampered by urban encroachment, smoke management issues, and forest fragmentation. For these and other reasons, fire has been excluded from many stands, resulting in the buildup of dangerous fuel loads. These fuel loads have begun to result in recurrent destructive wildfires. Already, different communities are responding to these dangerous fuel loads in various ways.

In response to a drying climate, an integrated property planning tool was developed over three years to help landowners make better use of available rainfall. A sequence was identified which indicated how parts of each property are affected by soil moisture limitations. The sequence was combined with soil properties to indicate targeted strategies for each location aimed to improve soil moisture availability, biomass utilisation, and long-term viability of the farm or ranching enterprise.

A range of tools have been proposed to support decision making in contaminated land remediation. From a European perspective it is clear, however, that there are considerable national differences in the decision support process, and more generally in the extent to which this process supports the selection of less invasive, alternative remediation options such as phytoremediation, in situ immobilisation etc. (referred to here as “gentle” remediation technologies).

Despite improvements in the use of soil conservation practices, crop rotation and managed fertilizer applications, large losses of nitrogen (N) in runoff continue to occur from row-cropped watersheds. Increasing requirements for implementing water quality standards in the United States, has increased pressure for the development of research-based guidelines to reduce N losses from agricultural runoff.
