    Investigations into nitrogen sources and supply in reclaimed colliery spoil (1986)
    Springer
    Plant and soil 91 (1986), S. 181-194 
    Details
    ISSN: 1573-5036
    Keywords: Colliery spoil ; Grass cultivar ; Legumes ; Nitrogen sources ; Nitrogen supply ; Phosphate level pH ; Reclamation

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Two trials were established to investigate the supply of nitrogen from ammonium and nitrate fertilizers, slow release nitrogen fertilizers, an organic nitrogen fertilizer and a legume, at two phosphate levels, to eight grass cultivars on colliery spoil. Spoil nitrogen supply and chemical characteristics and herbage dry matter and nitrogen yields were monitored for up to seven years. pH and conductivity fell at both sites. pH trends appeared to be independent of nitrogen treatment. Nitrogen in the ammonium form gave better yields than in the nitrate form when 125 kg N ha−1 was supplied in a season but there was no difference when 62.5 kg N ha−1 was applied. Slow release forms of nitrogen gave better yields more evenly distributed over the season than one application of ammonium sulphate per season. Once established white clover (Trifolium repens) plots had a more consistent nitrogen supply, more evenly distributed yield and better quality herbage than nitrogen fertilizer plots.Lolium perenne yielded poorly at low fertility.Festuca rubra andAgrostis castellana, although establishing slowly, yielded well under high and low fertility.
