CROPS AND CHEMISM OF PLANTS OF A MULTIVARIANT MODEL EXPERIMENT ON COAL COMBUSTION WASTE DEPOSITS. PART II (2012 – 2013)

TL;DRAbstract

Reclamation efficiency of composts produced from the mixture of municipal waste (Radiowo and ZUSOK), urban green waste composts (Complex), housing estate lawn mowing waste (plants) and sewage sludge, as well as mineral fertilizer (NPK – without the use of any organic fertilizer), was assessed in a model experiment on an ash soil. The experiment was launched in 2005 and continued until the end of 2013. Crops were collected and subjected to the analysis in 2005, 2006 and between 2011 and 2012. In the period between 2007 and 2010 no agrotechnical treatments were carried out, with the experiment being limited to mere observation of the natural (spontaneous) succession of plants. Reclamation doses of composts and sewage sludge were measured quantitatively, therefore they differed in the content of dry matter as well as in the contents of organic substances and minerals in the dry matter. The largest aggregated dry matter yield of plants (2005–2013) was reported in the Complex variant, and s
