2015

Sammendrag

Sommeren 2015 vil bli husket som kald og våt, med store nedbørmengder i enkelte perioder. Regnet på Østlandet fra midten av august vil bli husket spesielt godt. Til tross for dette ser kornavlingene ut til å bli like høye i 2015 som i 2014.

Sammendrag

The plant P uptake from sewage sludge and biochar was investigated in pot experiments after manipulating the waste pH by mixing with acidic compost leachate or high pH concrete waste at two levels. Available P was measured both wit passive DGT samplers and by P uptake in rye grass during three harvests. The treatment pH in waste was about 4 after waste was mixed with leachate, and 11.5 with concrete waste. The pH in the pot during grass production was approximately 6.5. The P uptake was significantly higher in the treated biochar pots, both after high and low pH treatment. The more extreme pH treatments gave the highest uptake. The DGT uptake gave the same broad picture for pots with biochar but not for pots with sludge. DGT uptake showed less diffenece between high and low pH treatments. The passive samplers correlated relatively well with the measured grass uptake.
