Item Open Access Soil and climatic causes of water mains infrastructure bursts(2012-10-15T00:00:00Z) Farewell, Timothy S.; Hallett, Stephen H.; Truckell, Ian G.Anglian Water plc. have recorded a recent rise in the number of bursts to water mains, impacting on the reportable serviceability of the network to the regulator. Cranfield University National Soil Resources Institute were asked to investigate and advise on potential environmental causes for this. This report Soil and Climatic causes of water mains infrastructure bursts forms a part of the contractual obligations entered into by Cranfield University with Anglian Water plc. and is provided for Anglian Water plc., submitted as a deliverable for Cranfield University project WU33701V as part of the wider Anglian Water plc. Burst mains and climate factors project.Item Open Access Soil and transport factors in potential distribution systems for biofertilisers derived from palm oil mill residues in Malaysia(Elsevier, 2019-10-08) Truckell, Ian G.; Shah, Hamid Ullah; Baillie, Ian C.; Hallett, Stephen H.; Sakrabani, RubenOil palm provides an important source of edible oils and fats, accounting for >30% of total global production and >55% of the international trade in these foodstuffs. The palms produce fresh fruit bunches, comprising several hundreds of small fruitlets, which are compressed and steamed to extract the oil. Soil nutrients in oil palm estates become depleted after decades of heavy harvesting and require fertilisers. Liquid palm oil mill effluent, solid empty fruit bunches and other residues can have deleterious environmental impacts and require careful management. The problems of residue disposal and soil nutrient impoverishment can be linked and managed by composting the oil palm mill residues and distributing the biofertiliser produced back to the plantation. Using case studies from West Malaysia we present an early stage practical tool for the planning of the distribution component of such a cycle. The computer-based tool uses multiple field-based and remote sensing data sources to integrate the effects of local soil conditions, transport distances, environmental protection and management priorities and then models customised distribution plans. The tool operates at plantation level and can be augmented with detailed local data, but the approach is extensible and potentially applicable to regional or national planning.Item Open Access The use and applications of the Soilscapes datasets(2011-07-01T00:00:00Z) Farewell, Timothy S.; Truckell, Ian G.; Keay, Caroline A.; Hallett, Stephen H.A Technical Manual to guide users through the uses and applications of the soilscapes datasets.
