Abstract

Incubation studies were conducted to assess the influence of various combination levels of alkaline power plant fly ash and sewage sludge on soil microbial activity. The Lakeland loamy sand and Cecil sandy loam soils: were mixed with 0; 15, 3.0 or 5.0 % (w/w) ash and 0 or 1.5 % composted sewage sludge. Respiration was strongly depressed in the 5 % ash treatments over 28 day. Sludge addition improved respiration in all ash treatments except the 5.0 % Yates or 3.0 % Gaston treatment The results indicate that high rates of fly ash to soils may hinder normal decomposition and nutrient cycling processes: This may be partially alleviated, however, by coapplication of a readily oxidizablfc organic substrate such as sewage sludge.

Özet

Bu çalışmada, termik sanü-al külleri ve atık çamurun değişik kombinasyonlarında toprak mikrobiyal: aktivitesi üzerine etkileri; inkiibasyon denemesi ile belirlenmeye çalışılmıştır. Araştırmada; Lakeland tınlı kumu ve Cecil kumlu tını, kuru ağırlık hesabına göre % 0, 1.5, 3.0 ve 5.0 kül. ve % 0 ve 1.5 oranında da kompost atık çamur ile karıştırılmıştır: 28 gün süresince% 5 kül uygulamasında solunum oldukça azalmıştır. % 5.0 Yates ve % 3.0 Gaston uygulaması hariç, çamur ilavesi bütün kül uygulamalarında solunumu olumlu etkilemiştir. Elde edilen sonuçlar; yüksek oranda uçucu külün toprağa uygulanmasının normal ayrışma ve besin element döngüsünü engelleyebileceğini göstermiştir. Ancak bu durum, atık çamur gibi kolayca okside olabilen organik substratların kül ile birlikte uygulanmasıyla kısmen giderilebilmektedir
