“…These concentrations are much greater than the critical external Ca concentration required for the maximum growth of temperate grasses and legumes (Bell et al 1989;Wheeler 1996). By way of contrast, weathered tropical soils typically have very low levels of exchangeable Ca (Kamprath 1984) and Ca deficiency occurs frequently in a range of crops when the exchangeable Ca concentration is < 1 cmol/kg (<1.5 QT Ca) (Adams & Moore 1983;Kamprath 1984;Bruce et al 1988;Cregan et al 1989;McCray & Sumner 1990).…”

“…Soil acidity (mostly pH less than 5.5) commonly develops in agricultural lands in association with building-up of organic matter, frequent application of mineral fertilisers, and leaching of nitrate [55]. Acidity also creates Al and Mn toxicity to plants [9,39,57] and inhibits root nodulation and N-fixation in legumes [1,[58][59][60][61]. Low soil pH reduces the growth and activities of many soil microorganisms and this eventually leads to lower plant productivity due to decreased organic matter decomposition and mineralisation [62,63].…”

Potential for Recycling Nutrients from Biosolids Amended with Clay and Lime in Coarse-Textured Water Repellence, Acidic Soils of Western Australia

Application of biosolids in soils is an efficient method of recycling nutrients from biosolids and it is considered even safer when it is modified after mixing and diluting with other suitable soil organic amendments. A variety of soil organic amendments, such as green manures and composts, are used for modifying and co-composting with biosolids. However, these may not be considered as appropriate biosolids disposal and remedial measures for soils with unique problems such as low soil pH, water repellence nature, and poor water and nutrient retention capacities due to soil textural issues. Historically, soil amendments such as lime, clay, and recently biochar are being applied for such problematic soils at Western Australia and these researches focused mostly on improvement in soil physical and chemical properties. However, studies with potential for applying modified biosolids with these amendments are not complete yet. This review focused on identifying such gaps in these studies from over 170 peer-reviewed key research and review articles published over decades to latest in these areas.

“…In addition, less extensive processing of the CPW resulting in a mix of fine and medium size shells would be cost effective and energy efficient. The reactivity of liming materials depends greatly on soil properties such as texture, organic matter content and base saturation (Thomas and Hargrove 1984;Gregan et al 1989;Saviozzi et al 1994). For this reason the prediction graphs of pH change presented will be most reliable on soils similar to those tested.…”

“…However, the study did not focus on residual inorganic C following CPW application and the equilibrium between its different pools. The carbonate pool is not as dynamic as the organic carbon pool with regard to the effects of agricultural management (Han et al 2007).…”

2008. Evaluation of fresh and aged clam processing wastes as potential agricultural liming materials for coastal area vegetable production soils. Can. J. Soil Sci. 88: 559Á569. Clam canning in New Brunswick generates 1800 t of clam processing wastes (CPW) annually. Thirty-year-old stockpiles of CPW must now be remediated to satisfy environmental regulations. This study examined fresh and aged CPW as potential agricultural liming materials for acid coastal vegetable production soils. Clam processing wastes were ground to three size fractions (B0.250 mm, 0.250 to B1.00 mm, 1.00 to B2.00 mm) and analyzed for calcium carbonate equivalent (CCE). They were then mixed with two soils of contrasting textures at three rates, in duplicate, and then placed in a control-plusfactorial pot experiment, with commercial agricultural lime of fine texture (B0.250 mm) as reference. During an 8-wk incubation, soil water pH and electrical conductivity (EC) were monitored biweekly. At 4 and 8 wk, a soil extract germination test was conducted using cress (Lepidium sativum L.) as an indicator plant. CPW of B1 mm raised soil pH with effectiveness increasing as particle size decreased. Application rates in function of the fineness to induce a given pH change (DpH) could be obtained using prediction graphs with high coefficients of determination (r 2 : 0.84 to 0.97). The average EC in all treatments to the end of the incubation period was B2 dS m(1 , indicating that salt stress is not a risk following CPW application to soil, since even sensitive crops are capable of withstanding such an EC. Seeding could take place between 4 and 8 wk after the CPW application to loamy sand with no adverse effect on germination index. In the loam soil, this period could safely be shortened.Key words: Clam, liming, soil pH, soil EC, cress, germination index Owen, J., LeBlanc, S., Toner, P., Nduwamungu, C. et Fava, E. 2008.
