The overall purpose of the project is to generate a base for recommendations for construction of new subsurface drainage and re-drainage of clay soils in the area Water - resource efficient management. Efficient drainage of arable land is important to increase crop production, to achieve environmental goals for eutrophication and to reduce effects of climate change (frequent heavy rainfall and dry periods). We want to investigate how different filter materials affect the sediment deposition in the drainage pipes, nutrient leakage of nitrogen and phosphorus as well as yield and quality of the crop. We will also assess the need for maintenance and the long-term sustainability of drainage systems. The results will guide farmers to encourage them to make necessary investments and efforts.
The project is at levels 4-7 on the TRL scale: the field trial will be a combination of applied research (TRL4), concept verification of the filter material (TRL5) and a demonstration in the field (TRL7).
Projektets övergripande syfte är att fram ett underlag för rekommendationer för anläggning av ny dränering och omdränering av lerjordar inom området Vatten – resurseffektiv hantering. En god dränering av åkermarken är viktig för att öka jordbrukets produktion, att nå ställda miljömål gällande övergödning och för att minska effekterna av klimatförändringarna (frekventa skyfall och torrperioder). Vid täckdikning används filtermaterial och vi vill undersöka hur olika filtermaterial påverkar slamavsättningen i dräneringsledningarna, näringsläckaget av kväve och fosfor samt grödans avkastning och kvalitet. Vi gör även en bedömning av underhållsbehovet och dräneringssystemens hållbarhet på lång sikt. Resultaten ska vägleda lantbrukare att våga göra de investeringar och arbetsinsatser som behövs.
Projektet ligger på nivå 4–7 på TRL-skalan eftersom fältförsöket blir en kombination av tillämpad forskning (TRL4), konceptverifikation av filtermaterialet (TRL5) samt en demonstration i fält (TRL7).

Even if Sweden is historically regarded as a water-affluent country, lately sustainable water use and water circularity have become topics of high concern. Irrigation is dependent on high quality water resources, and the need for accessible water resources becomes stronger under exceptionally dry …

An improved strategy for agricultural drainage is important for both economic and environmental reasons. There are indications on environmental benefits of a good drainage but lack of studies that directly shows this. The aim of the project is to develop a basis for design recommendations for new …

Swedish biogas production is crucial to reach environmental and climate targets and manure represents a great potential, corresponding to ca 2,7 Twh. However, the production from manure-based facilities currently only reaches around ca 64 GWh. Due to the character of manure it is difficult to reach …

The use of fungicides in potatoes is in many cases unnecessarily large in relation to the risk of infestation of late
blight and tuber blight. With increased and better knowledge of potato late blight and tuber blight, the average control
intensity can probably be reduced by 25–50%. With the …

Cultivation of legumes will increase due to several factors. Among these are extraction of plant-based proteins for human consumption, a demand for increased self-sufficiency of vegetable proteins within the country, reduced costs for fertilisers by N-fixation in the legumes, and use of legumes as …
