| Background: Phosphorus recycling from waste and localised placement of fertilisers can be means to 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 shoot and root growth of maize was followed for 30 days. 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.... |
