Beneficial Effects of Biosolids on Soil Quality and Fertility Literature Review
ISBN: 1 84057 173 X
Application of biosolids, usually at a rate of 250 kg N ha -1 , will typically apply 5- 8 tds ha -1 , equivalent to 2- 4 t OM ha -1 . Regular application of biosolids at this rate will lead to slow but progressive increases in soil OM content. Biosolids OM has been shown to influence a number of soil physical, chemical and biological properties, which in turn have a positive impact on soil quality and fertility. There is a requirement that the soil conditioning and fertiliser replacement value of a range of biosolids including new products is evaluated under UK conditions and at appropriate agronomic rates. This, would provide scientifically based information on the agronomic value of biosolids from which advisory and promotional information could be developed.
