30period should not be used for storage.• The type of soil at the site should not be such that there is rapid penetration through thesoil profile. Sandy soil should therefore be avoided. Heavier soils can be surface-workedprior to composting to avoid rapid penetration through cracks and wormholes.• The groundwater level on the site should not be too close to the surface and there shouldbe no risk of the groundwater rising to the surface during the composting period.• The compost should not be placed on a site which acts as a replenishment area for theabstraction of drinking water.• Composting should not be carried out directly above known drainage pipes.• Application of the fertiliser should not damage the ground.• The composting site should be chosen such that nearby residents are notinconvenienced by odours or flies.• The compost should be arranged in a way that promotes composting, for example byadjusting the amount and distribution in the pit to avoid a lack of oxygen.1. Is there any official quantified goal that states to what extent this measure should beimplemented? No• If "Yes";a) specify quantity and unit:b) if applicable, what year to be realized?c) give reference(s):• If "No", what is your expert opinion of the desirable level in 5 years?quantity and unit: A closed cover on storages with urine and digested manure2. To what extent is this measure implemented today in relation to goal set above? 10"0"=Not at all; "10"=Goal already reached3. If goal is not reached; how do you judge the possibilities to fulfill it?"0"=Impossible; "10"=Very goodComments: 98% of liquid manure storages and 94% of urine storages are covered withaccepted methods including natural crust (SCB, 2010. Use of fertilisers and animalmanure in agricutlure in 2008/09. MI30SM1002. Statistics <strong>Sweden</strong>. 102 pages)Comments on why the goal is easy/difficult to reach, what are the most importantparameters in your country:Almost all liquid manure pits and urine pits has a coveraccording to what covers are permitted. A future goal is then to have a more efficient coveron storages with urine and digested manure, i.e. not only a cover of a natural crust but amore closed cover (Andersson et al. 2010).Is this measure regulated in legislation? Yes If “Yes”; national or regional rulesReference(s) to legislation:Section 6 of Ordinance (1998:915) on environmental concernsin agriculture lays down requirements for minimum livestock manure storage capacity.Agricultural holdings with an annual average of no more than two livestock units areexempted from these requirements.General guidance on Section 5a of Swedish Board of Agriculture rules (SJVFS 2004:62)

Yes If “Yes”; national or regionalsubsidy rulesReference(s) to subsidy rules:The swedish rural deveopment programme 2007-2013.Comments: Investment support is possible for investments that aims at creating a largerstorage capacity than required or if the enhancment is needed due to larger livestock. Thisis also optional for each County Board if they choose to support the investment or not.11. Constructed wetlands for nutrient reduction/retention11.1 Sedimentation pondsSmall surface flow wetlands designed primarily to retain phosphorous. This isachieved by retaining eroded phosphorous bound to aggregates and particulatematerials in the run-off water by optimizing the conditions for sedimentationprocesses. To some extent phosphorous and other nutrients are reduced due tobiological and chemical decomposition and transformation processes as well as plantuptake.A sedimentation pond is suitable for establishment in highly intensive small-scaleagricultural areas. The ponds are relatively small representing approximately 0.1 –0.5 % of the run-off area. The sedimentation pond is constructed for instance bywidening a section in a ditch into a sedimentation pond slowing down the speed ofthe run-off water hence increasing sedimentation.A sedimentation pond is often designed as a serial combination of (i) a sedimentationbasin with a water depth of 1-1.5 m representing 20-30% of the total area of thesedimentation pond where the main sedimentation of larger particles takes place,followed by (ii) a wetland filter covered with typical wetland plants providing goodconditions for sedimentation of smaller particles. In case the area is highly sloped it issuitable to include an overflow area followed by a second wetland filter prior to theoutlet to further induce the sedimentation efficiency.The accumulated sediments in the sedimentation basin need to be removed onregular basis for maintenance.Describe this measure in your country if different :
