“…For this reason, several authors such as Sertsu and Sánchez (1978), Giovannini et al (1990) and Soto (1993) developed laboratory heating programmes in order to record the influence of temperature on soil physical and chemical characteristics, or only on the physical ones (Ulery et al, 1993). Other studies analysed the effect of adding ashes on the soil nutrients (Ohno and Erich, 1990;Erich, 1991;Huang et al, 1992;Marcos et al, 1993-94) or even the effect of the heat-ash interaction (Sharrow and Wright, 1977;Raison and McGarity, 1980;Kutiel and Shaviv, 1989;Soto and Díaz-Fierros, 1993).…”

Changes in a Humic Cambisol heated (100–500 °C) under laboratory conditions: The significance of heating time

The influence of the temperature and its duration, that are among the most important components to determine the fire effects on soil properties, were studied in the 0-5 cm layer of a Humic Cambisol developed over siliceous conglomerates and under a shrub of Erica australis. Soil was sandy loam with 8.5 g 100 g − 1 of organic matter, pH of 4.7 and available P about 0.16 mg kg − 1 . The water stability index (WSI) was 64.9, which was considered good. Differential thermal analysis (DTA) showed the presence of two peaks, one endothermic until 177°C and other exothermic between 229°C and 579°C. Samples were heated at 100°C, 200°C and 500°C during 5, 15, 30 and 60 min after reaching the selected temperature. To avoid a temperature gradient in the profile a sample layer of 2 cm depth was used. Soil heating to 100°C at the four heating times and to 200°C for 5 min did not produce significant changes in pH, organic matter, total N, C/N ratio, available P, extractable cations and WSI. Soils heated to 200°C for 15, 30 and 60 min and 500°C for 5 min, showed a significant increase in available P (from 0.9 to a maximum of 17.6 mg kg −1 ) and divalent cations (Ca 2+ from 4.4 to 46.3 and Mg 2+ from 1.5 to 8.7 mg kg − 1 ). For soils heated to 500°C for 15, 30 and 60 min, a clear increase in soluble Na + content (from 0.5 to 1.8 mg kg −1 ) and pH (from 5.5 to 8.1), in addition to a significant decrease in organic matter (from 8.7% to 2.4%) was detected. As a consequence an important decrease in WSI was found (from 64.9% to 54.3%).

“…Although an important fraction of the K contained in ashes should form insoluble complexes as a consequence of the high temperatures reached during the combustion of olive wastes (Lewis and Schmidt 1986), another fraction should be soluble and, as a consequence, should be rapidly available in the soil and extracted by crops (Ulery et al 1993;Nogales et al 2006). Phosphorus (3.5-17 g kg À1 ), Ca (22-181 g kg À1 ), Mg (8-22 g kg À1 ), and Na (1-16 g kg À1 ) concentrations in the ashes from olive wastes were similar to those from wood, paper, pulp, and coal (Huang et al 1992;Jala and Goyal 2006;Ohno and Erich 1993). Therefore, olive waste ashes may be a direct source of P, K, Ca and Mg for soils, although the Ca and Mg contents in those ashes were less than those in liming agents currently used in agriculture.…”

“…Nickel concentrations (12-54 mg kg À1 ) were lower, and Pb (3-70 mg kg À1 ) was only detected in fly ashes and not in bottom ashes. Compared with ashes from coal and wood, the Cu and B contents in those from olive wastes were higher, whereas the contents of other trace elements were lower (Huang et al 1992;Jala and Goyal 2006;Pitman 2006). However, owing to the broad ranges, comparisons are difficult for these trace elements.…”

Recycling of Biomass Ashes

Wet and dry olive cakes are the most important wastes generated when olive oil is produced. In recent years, both olive wastes have been incinerated to produce electricity, and thereby large amounts of fly and bottom ash are generated. In this study, physical, physicochemical, and chemical characteristics of olive waste ashes produced in Andalusian biomass power plants were analyzed to evaluate their suitability for agriculture. High variability among fly and bottom ashes may be ascribed to the origin of the olive waste and the combustion temperature. Waste olive ashes, which contained all particle sizes, showed high values of pH, salinity, water holding capacity, calcium carbonate equivalent, and P, K, Cu, and B contents. In contrast, moderate values were recorded for Ca, Mg, Zn, and Ni. Nitrogen is scarce in olive waste ashes; they thus can only be part of any fertilization strategy.

“…For this reason, spreading of wood ash on agricultural and forest soils as well as in cut-away peatlands with high acidity and/or low fertility has been previously studied. Several experiences were made with satisfactory results (for example : Erich 1991, Huang et al 1992, Huotari et al 2011. Some studies show a faster reaction of ashes than that of lime in the soil (Clapham andZibilske 1992, Muse andMitchell 1995), with higher initial pH increase in ash amended soils, although maintained in a shorter period of time.…”

Spreading wood ash on forest and agricultural lands has been used for years to correct pH in acid soils and as a source of plant nutrients. However, it is necessary to enhance the knowledge of potential hazards derived from such a practise. Surface runoff pollution is one of these possible hazards. In this work we studied the quality of runoff water collected in two sloped forest plots before and after wood ash spreading, with the aim of checking potential undesirable effects of ash use. We have not found environmental pollution problems in runoff derived from the ash application zones. These results encourage further research and use of wood ash as an amendment in acid sloped forest soils.
