“…Usually ash fertilization does not improve tree stand production on mineral soil forests (Jacobson 2003, Saarsalmi et al 2004, probably because on those nitrogen and not K or P limits tree growth. However, on peat soils K and P deficiency is common and may limit tree growth (e.g.…”

Fertilization of drained peatland forests with wood ash and different commercial phosphorus fertilizers (calcium phosphates) generally give similar stand growth responses. However, it has been shown that use of calcium phosphate fertilizers generally lead to highly increased P release to recipient water courses. On the other hand, no corresponding release has been reported after ash fertilization. Soil samples from the surface peats from a nutrient poor and a fertile drained peatland site were collected before and 1-4 years after application of five different types of ash products. The changes over time in the different chemical forms of P in the substrate were studied. The results indicated that the reason for the low liability to leaching of ash fertilizers was that significant amounts of P are adsorbed by Al and Fe during weathering of the ash fertilizers. However, further studies are needed to clarify whether the adsorption of P occurs with the Al and Fe of the ash or the native Al and Fe compounds present in soil before ash fertilization.

“…Strudley et al [11], observed that tillage methods and intensity have various effects on the soil physical and chemical properties that affect plant growth and crop yield. Also wood ash have been reported by Vuorinen and Kurkala [12] and Jacobson [13] to have positive effect on Ca, K, content of soil as well as an increase of K, Mg, S, B, Fe and Zn in tissue of the Scots Pine.…”

The effect of tillage methods (Mound, Ridge, Flat) and rates of wood ash on soil properties and yield of castor bean plant were studied in field trial at Abakaliki for 3 years cropping seasons. The experiment was a split plot in randomized complete block design with three tillage methods and four rates of wood ash (0 t•ha ), replicated three times. CropStat Version 7.2 computer software for data management developed primarily for the analysis of data from agricultural field trials was used to analyze data collected from the study and mean separation was done using least significant difference (LSD) at 5% alpha level. The findings from the study showed for soil heavy metal contents, it was observed that tillage methods had no effect on the heavy metals except for 1 st year cropping result of Zn and 2 nd year cropping result of Fe. The effect of tillage methods on heavy metal contents of castor shoot showed a significant difference P < 0.05 except for 3 rd year result of Fe. The values obtained from Ridge and Flat were higher when compared with the value of Mound with regard to soil and castor shoot; heavy metal content with higher values was more observed in Flat method. The result of heavy metal content of seed indicated that tillage method had no effect on the heavy metal contents of the castor seed; the results of Fe, Zn in 1 st and 2 nd year planting season were not significant among the rates of wood ash applied. The effect of tillage and wood ash on heavy metal content of soil, castor shoot and seed was found to be significant (P < 0.05). The values obtained decreased as the planting season increased, and the amount was found to increase as the rates of wood ash application increased. The effect of Ridge and wood ash at the rates of 2 t•ha −1 (Rd 2 ), 4 t•ha −1 (Rd 4 ) and 6 t•ha −1 (Rd 6 ) on Fe 2 nd year planting result of castor seed was statistically similar, while the result from Mound method was found to increase the seed uptake of the tested parameters.The observed values of the tested parameters (Fe, Zn) in wood ash amended plots in the three years' study were beyond acceptable limits; hence reservation in the use of wood ash How to cite this paper: Nweke, I.A., Mbah,

“…Guerrini et al (2000) found that wood ash and paper sludge applications on predominantly sandy soils can increase growth in the range of 38% to 64% relative to chemical fertilizers. The addition of a supplementary nitrogen-rich nutrient source has been shown to increase growth and is recommended if improved growth responses are anticipated from wood ash additions (Demeyer et al 2001, Jacobson 2003, Elliott & Mahmood 2006.…”

A field trial was established to test the effects of various wood ash and fertilizer application rates on the nutrition and early growth of a clonal Eucalyptus grandis × urophylla stand near Richards Bay, KwaZulu-Natal province, South Africa. The trial consisted of wood ash treatments of 0, 0.3, 0.6 and 1.2 t ha -1 , combined with fertilizer treatments of no fertilizer (control), 150 g tree -1 of conventional ammonium sulphate fertilizer or 320 g tree -1 of controlled release fertilizer mixture containing N, P and a balanced suite of several plant nutrients. The experiment was conducted on a young sandy soil of aeolian origin with a very low buffer capacity. Ash application rates were chosen after a pilot study was conducted to test the effect of CaCO3 on the soil reaction. At 4 and 8 months after treatment, soil heavy metal concentrations for cadmium (Cd), mercury (Hg), chromium (Cr) and lead (Pb) levels were substantially lower than toxic levels. Foliar heavy metal concentrations (for the same elements) were less than 1mg kg -1 at both time intervals. The wood ash induced a temporary liming effect up to 8 months after application. Foliar nutrient assessments revealed sub-optimal nutrient concentrations for phosphorous (P), potassium (K) and zinc (Zn) at 4 months and K at 8 months of age. The positive growth responses (expressed as a biomass index) at 8 months, ranged between 13% and 683% relative to the untreated control. At 21 months, the growth response to ash and fertilizer combinations ranged from -0.5% to 50% relative to the control. This research demonstrated that 1.2 t ha -1 of wood ash can safely be disposed of on a typical, poorly buffered Zululand coastal sand with little environmental risk and minimal growth suppression, provided that it is balanced with an appropriate NPS plus trace element fertilizer mixture.
