Abstract Decreased phosphorus (P) losses and improved environmental quality are crucial to consider while recycling farm wastes and adding various soil amendments. This study investigated the impact of coal and wood ash on the extractability of P from soils (sandy loam and loamy sand) amended with organic and inorganic phosphorus fertilizers. These soils were further amended coal and wood ash, and analyses were carried out to quantify the water-, Olsen-, and Mehlich 1-extractable P. Ratio of the ashes applied to soils were 5% to sandy loam soil while 10% to loamy sand soil. Water-extractable P was observed to be mainly dependent on the ash type as well as the extraction method. Ash amendment reduced the solubilization of P across soils up to 9% and 23% and 7% to 17% upon 5% and 10% ash amendment in loamy sand and sandy loam soils, respectively. However, the water-extractable P was found to be low in wood ash-amended soil as compared to coal ash. Interestingly, this extractability was greater in soils treated with inorganic P. Phosphorus extraction from soil followed the trend as Mehlich 1 > Olsen > water. P leachability was found to be mainly dependent on ash amendment but values were high for the soil treated with inorganic P. The study inferred that using ash materials such as coal ash and wood ash can be a practical measure for moderating P losses from soils important for economic and environmental perspectives.

Introduction There has been a great interest in using farmyard manure and several organic and inorganic amendments to reduce the soil contamination and improve soil fertility and crop

production (Ali et al. 2017; Bhogal et al. 2011; Mooleki et al. 2004; Rehman et al. 2018). When applied to the soil, manure is a valuable resource of fertilizer and soil amendment for crop production (Mando et al. 2005; Qayyum et al. 2017a, b), but in excess, this may pollute soil and water ecosystems (Bouraima et al. 2016; Xiong et al. 2010). The intensive use of inorganic fertilizers has aggravated the
