“…Error bars indicate standard errors (n=3) Garg et al 2005;Kishor et al 2010). This means that fly ash contains most elements required for plant growth and metabolism, with the exception of nitrogen and available phosphorus (Singh and Yunus 2000).…”

The aim of this study was to assess the seasonal development of the physicochemical (pH, organic C, organic N, extractable P, Ca(2+), Mg(2+)) and biological soil properties (microbial biomass, activities of urease, dehydrogenase and alkaline phosphatase) of the topsoil of mine deposition sites that differed based on the material used exclusively for their creation: (a) marlstones, (b) red-grey formations (RGF), and (c) fly ash (FA), during the first year after their creation. Our hypothesis was that all deposition sites, regardless the material they consist of, present equal opportunities for the establishment of spontaneous vegetation. All macronutrients concentrations (P, Ca(2+), and Mg(2+)) remained constant with time and were found to be higher in the FA sites. Organic C, organic N, all enzyme activities, and microbial biomass were higher in the RGF and marl depositions, with marl sites presenting the highest values. All values of biological variables, with the exception of alkaline phosphatase, increased with time. The alkaline environment along with the slow improvement in soil biological properties of the FA sites seemed to present the most unfavorable conditions for spontaneous vegetation growth. On the contrary, the other two spoil materials presented significant improvement in the initial stages of soil formation in terms of soil functionality.

“…Bulk density of fly ash varied from 1 to 1.8 g cm -3 , Water holding capacity of the fly ash was generally 49-66 per cent on weight basis, while the moisture retention ranged from 6.1 per cent at 15 bar to 13.4 per cent at 1/3 bar (Prem Kishor et al, 2010). The coal fly ash generally had a silt loam texture, with 65-90 per cent of the particles having diameters of less than 0.010 mm.…”

“…Several study results revealed that the utilization of coal fly ash for agricultural effort was more effective if combined with organic matter (Aggarwal et al, 2009;Kishor et al, 2010). Organic acids from organic matter decomposition such as humate and fulvate have very reactive functional groups such as -COOH, -OH (phenolic, alcoholic) which have an important role in increasing P availability in soil (Haynes and Mokolobate, 2001;Yang et al, 2013).…”

Low P availability is the main constraint for crops on acidic soil such as Ultisols due to high soil P sorption. The objective of current research was to determine the effect of coal fly ash-chicken manure mixture application on P use efficiency by corn (Zea mays L.) on Ultisols. The research was arranged according to Factorial Completely Randomized Design with three replicates. The treatments tested were the rates of FA-CM mixture (w/w of 1:1) which consisted of 0, 15, 30, 45 and 60 tons ha -1 , and P fertilizer rates that consisted of 0, 0.5, 1.0, 1.5 and 2.0 times of P requirement to achieve 0.2 μg P mL -1 in soil solution (equivalent to 0, 87, 174, 261 and 348 kg P 2 O 5 ha -1). Results of current research showed that P use efficiency by corn on Ultisols had been increased through the addition of FA-CM in combination with P fertilization at the rate of 87 kg P 2 O 5 ha -1 . The optimum rate of FA-CM in combination with P fertilizer at the rate of 87 kg P 2 O 5 ha -1 was 28.60 tons ha -1, with P uptake efficiency of 42.41 % and agronomic P efficiency of 82.53 mg shoot dry weight/mg P from fertilizer.
