dc.description.abstract |
The water industry recognises significant cost advantages in recycling sewage sludge (biosolids) to
agricultural land compared with alternative more expensive disposal options such as incineration or
landfill. A recent technique was proposed by United Utilities plc for the production of organomineral
fertilisers (OMF) from biosolids granules which adds additional nitrogen to the biosolids’ nutrients
to form a balanced NPK fertiliser. The aim of this research was to determine the effects in cereal and
grass crops of using organomineral fertilisers (OMF) made from nutrients-enriched biosolids
granules and to contribute towards the understanding of nutrient management and dynamics in
agricultural systems. The research included soil incubation, glasshouse, lysimeters and field studies
which used winter wheat (Triticum aestivum L.) and ryegrass (Lolium perenne L.). A theoretical
model was developed for fertiliser particle distribution studies which required the determination of
key physical properties of the products. Two OMF formulations have been suggested: OMF10 and
OMF15 which have the following NPK compositions: 10:4:4 and 15:4:4 respectively. These were
suggested for use in grassland as well as arable cropping. The particle trajectory model showed that
the particle size range for OMF10 and OMF15 should be between 1.10 and 5.50 mm and between
1.05 and 5.30 mm in diameter respectively. Cont/d. |
