Soil Survey in Sweden
نویسنده
چکیده
However, they played an important role in the understanding of soil properties and land use planning, and came later to provide a useful basis for national soil mapping. The geological surveys gave rise to the so-called Quaternary and Petrological Maps, the first one being published 1857. The maps show mineralogy and texture and genesis of the parent material, e.g. texture of glacial till and water or wind deposited sediments, and occurrence of peat and gyttja.

Quantification of Plasmodiophora brassicae Using a DNA-Based Soil Test Facilitates Sustainable Oilseed Rape Production
Outbreaks of clubroot disease caused by the soil-borne obligate parasite Plasmodiophora brassicae are common in oilseed rape (OSR) in Sweden. A DNA-based soil testing service that identifies fields where P. brassicae poses a significant risk of clubroot infection is now commercially available. It was applied here in field surveys to monitor the prevalence of P. brassicae DNA in field soils inte...

متن کاملOutcomes of applying a geopedologic approach to soil survey in Iran
The paper reviews a set of soil surveys carried out in Iran using a geopedologic approach for different surveying aims in different scales. Most of these studies have implemented a similar survey method including the following steps: delineation of landforms from air photos using geomorphic and soil-landscape relationships, field check of the delineations, sample areas inventory with soils clas...
متن کاملTargeting critical source areas for phosphorus losses: Evaluation with soil testing, farmers’ assessment and modelling
Diffuse phosphorus (P) losses from arable land need to be reduced in a cost-efficient way, taking into account their temporal and spatial variability. This study, based on 16 farms across southern Sweden, examined possibilities for identifying critical source areas for P losses based on the combined results of high-resolution erosion modelling, independent risk assessments by farmers, soil surv...
