Abstract Most arid and semi-arid soils, especially calcareous sandy soils, are widely distributed in the Middle East region; the deficiency in their content of many nutrients particularly phosphorus and organic matter limits crops production. This study aimed to assess the effects of adding biochar (B) with farmyard manure (FYM) and poultry manure (PM) on some soil properties, phosphorus (P) availability, and barley growth in calcareous sandy soil. The pot experiment includes the following treatments: Control, B, B + FYM (1:1), B + PM (1:1), B + FYM (2:1), B + PM (2:1), FYM + B (2:1), and PM + B (2:1). Biochar combined with FYM and PM enhanced the water holding capacity (WHC) and soil organic matter (SOM) content in calcareous sandy soil. Phosphorus availability was increased significantly by applying biochar mixed with farmyard manure and poultry manure at all treatments. Green biomass of barley improved because of adding biochar alone, poultry manure alone, and biochar co-applied with poultry manure at all mixing ratios. Biochar application caused significant increases in phosphorus use efficiency (PUE) by barley plants compared to all other treatments, except for the control. We recommend adding biochar either individually or mixed with poultry manure to improve the productivity of calcareous sandy soil. Keywords Barley . Biochar . Biomass . Phosphorus use efficiency
Introduction Phosphorus (P) in soil is an important nutrient for crop and food production. It can be added to the soil during agricultural processes from two sources: (1) natural due to the processes of biogeochemical soil forming (2) anthropogenic P as fertilizer and manure (Sattari et al. 2012; Zhang et al. 2017). Currently, agriculture depends on phosphorus fertilizers produced from non-renewable phosphate rock, which its reserves estimated to be depleted in approximately 50–100 years. In 2030, the global peak in phosphorus production is expected to happen as a result of the increasing demand of phosphorus (Cordell et al. 2009). Therefore, the rate and amount of phosphate rock dissolution attribute to several factors which are chemical composition, particle size of the phosphate rock, and soil This article is part of the Topical Collection on Implications of Biochar Application to Soil Environment under Arid Conditions * Abu El-Eyuoon Abu Zied Amin [email protected]; [email protected] 1

properties, such as pH and moisture content, as well as calcium and phosphorus concentration in soil solution (Sanyal and De Datta 1991). The phosphorus adsorption, precipitation, and immobilization into unavailable forms in soil are resulting from phosphate fertilizers that are usually added in excess of pl
