Última Opportunity costs for maize associated with localised application of sewage sludge derived fertilisers, as indicated by early root and phosphorus uptake responses Organic Eprints Lemming, Camilla; Oberson, Astrid; Hund, Andreas; Jensen, Lars Stoumann; Magid, Jakob. Background: Phosphorus recycling from waste and localised placement of fertilisers can potentially improve sustainable P management in agriculture. However, knowledge about root and plant P uptake responses to placement of complex waste-derived fertilisers is lacking. Methods: Sewage sludge (SS) and sewage sludge ash (ASH) were tested against triple superphosphate (TSP) in a rhizobox setup where maize shoot and root growth and architecture were followed for 30 days. The three P sources were either mixed homogenously into the soil (slightly acidic, low in available P and moderate P fixing capacity; labelled with 33P) or localised in a patch close to the seed. Results: Localisation of TSP and SS both induced increased root length density in and around the... Tipo: Journal paper Palavras-chave: Composting and manuring.

The three P sources were either mixed homogenously into the soil (labelled with 33P) or localised in a patch close to the seed. Results: While localised TSP and SS both increased root length density around the fertiliser patch, it was at the expense of the remaining root system and soil P uptake for SS....

Ano: 2015 URL: http://orgprints.org/29273/7/29273.pdf Maize root growth and P uptake dependency on spatial distribution of sewage sludge, sewage sludge ash, and TSP Organic Eprints Lemming, Camilla; Oberson, Astrid; Jensen, Lars Stoumann; Magid, Jakob. Shoot P uptake from TSP was largely increased by the localized placement. For the ASH, the localized placement clearly decreased shoot P uptake from the ash. For Sewage Sludge, localized placement decreased P uptake from the soil whereas P uptake from the sludge was almost unaffected. • Overall, total shoot P uptake was significantly affected by the treatment (p<0.005).
