1. 1. Effect of liming and free Ca2+ on Cd uptake of carrots, Daucus carota

   Master-uppsats, SLU/Horticulture (until 121231)

   Författare :Anna Holmkvist; [2009]
   Nyckelord :Cd; carrots; Cd uptake; Ca; substrate; nutrient solution ; calcium; cadmium;

   Sammanfattning : The level of cadmium (Cd) in Swedish arable land has increased during the last century and the average concentration of Cd in the plough layer is today 0.23 mg/kg. The increase is mainly due to anthropogenic activities such as phosphorus fertilizing, liming, import of feed, and atmospheric deposition from industrial emissions. LÄS MER

3. 2. Potato yield and soil physical properties as affected by subsoiling

   L3-uppsats, SLU/Agrosystems (until 121231)

   Författare :Anna Holmkvist; [2008]
   Nyckelord :soil compaction; soil strength; root development; potato; solanum tuberosum; potato production; deep tillage; bulk density; subsoiling; potato yield; potato quality; inter-row subsoiling; chiseling; plough pan; infiltatation; zone tillage;

   Sammanfattning : Agriculture practices today include the use of heavy machinery which leads to soil compaction. High soil strengths are known to restrict the root development and prevent root growth. Sandy soils, which often are used in potato production, seem to be especially susceptible to subsoil compaction. LÄS MER
