Abstract

Established fertilizer recommendations for wheat is urgently required to enhance the application efficiency of commercial phosphorus (P) fertilizers. This study evaluated the effect of inorganic P combined with some organic supplements i.e., citric acid (CA) or pigeon manure juice (PMJ), on alkaline-calcareous soil as well as plant measurements and phosphorus efficiency parameters of wheat (Triticum durum ’Boussalem’). Different concentrations of P in solution i.e., 0.05, 0.10, 0.15, 0.20, and 0.40 mg l−1, were worked out theoretically using the Freundlich model. A greenhouse study was conducted on a permanent layout with three replicates. As a result, phosphorus in the control was 0.493 mg P pot−1. However, in amended pots with organic substances, the averages of P uptake were 0.701 and 0.785 mg P pot−1, respectively for PMJ and CA treatments. A lower P requirement of 0.195 and 0.245 mg P l−1 may be required in CA and PMJ treatments, compared to the control treatments (0.345 mg P l−1). In addition, the phosphorus absorption efficiency (PAE) was higher in the CA and PMJ treatments. So, it is recommended to apply P fertilizers with poultry manure juice as an alternative solution in order to improve the efficiency of inorganic P fertilizers and consequently reduce their application rates in alkaline calcareous soils.

Highlights

Calcareous sandy soils in arid regions suffer from poor physical and chemical fertility because of their low organic matter content and low water retention beside their poverty (Brady & Weil, 1999)
Phosphorus is one of the more expensive nutrients required for wheat production and its use efficiency is induced by soil properties, especially in calcareous soils, which are dominant in the Mediterranean region
Improvement in phosphorus nutrition of wheat plants grown in a ... chemical phosphorus fertilizer with some selected organic substances available P was extracted with 0.5 N NaHCO3 (Watanabe & Olsen, 1965) and concentration was measured by the colorimetric molybdate–ascorbic acid method (Murphy & Riley, 1962)

Summary

Introduction

Calcareous sandy soils in arid regions suffer from poor physical and chemical fertility because of their low organic matter content and low water retention beside their poverty (Brady & Weil, 1999). It is well known that wheat is a major cereal crop that feeds most of the world’s population, especially the Mediterranean region. It is one of the largest cereal crops in terms of cultivated areas around the world (Royo et al, 2017). Phosphorus is one of the more expensive nutrients required for wheat production and its use efficiency is induced by soil properties, especially in calcareous soils, which are dominant in the Mediterranean region. P use efficiency (PUE) in wheat is only about 5~10 % in the year of addition, where most of the phosphorus added to the soil is fixed (Ma et al, 2005)
