“…3 and 4 , we find that the response of chickpea crop to the Poly-P application is strongly influenced by soil moisture content. Although the Poly-P fertilizers have beneficial effects on plant photosynthesis and growth under optimal irrigation conditions 25 , 26 , 60 – 62 , their effectiveness is greatly reduced under water stress conditions, unlike the Ortho-P fertilizer which exhibits a stable effect on plant growth even under water stress conditions. These changes in chickpea plants’ phenotype (specific leaf area and canopy) and growth (biomass accumulation and allocation) can be associated with the impact of different water and P supply regimes on photosynthesis efficiency 63 – 65 .…”

Water shortage and soil nutrient depletion are considered the main factors limiting crops productivity in the Mediterranean region characterized by longer and frequent drought episodes. In this study, we investigated the interactive effects of P fertilizer form and soil moisture conditions on chickpea photosynthetic activity, water and nutrient uptake, and their consequent effects on biomass accumulation and nutrient use efficiency. Two P fertilizer formulas based on orthophosphates (Ortho-P) and polyphosphates (Poly-P) were evaluated under three irrigation regimes (I1: 75% of field capacity, I2: 50% FC and I3: 25% FC), simulating three probable scenarios of soil water content in the Mediterranean climate (adequate water supply, medium, and severe drought stress), and compared to an unfertilized treatment. The experiment was conducted in a spilt-plot design under a drip fertigation system. The results showed significant changes in chickpea phenotypic and physiological traits in response to different P and water supply regimes. Compared with the unfertilized treatment, the stomata density and conductance, chlorophyll content, photosynthesis efficiency, biomass accumulation, and plant nutrient uptake were significantly improved under P drip fertigation. The obtained results suggested that the P fertilizer form and irrigation regime providing chickpea plants with enough P and water, at the early growth stage, increased the stomatal density and conductance, which significantly improved the photosynthetic performance index (PIABS) and P use efficiency (PUE), and consequently biomass accumulation and nutrient uptake. The significant correlations established between leaf stomatal density, PIABS, and PUE supported the above hypothesis. We concluded that the Poly-P fertilizers applied in well-watered conditions (I1) performed the best in terms of chickpea growth improvement, nutrient uptake and use efficiency. However, their effectiveness was greatly reduced under water stress conditions, unlike the Ortho-P form which kept stable positive effects on the studied parameters.

“…The remaining soil residue was digested with H 2 SO 4 and HClO 4 to determine the residue-P. Soil NaHCO 3 -P, NaOH-P, HCl-P and residue-P were measured through the molybdenum blue colorimetric method at an 880 nm wavelength, while for resin-P measurement, the malachite green colorimetric method was employed because the concentration of resin-P was usually low (Kang et al, 2021).…”

Phosphorus (P) fertilizers have long been applied in agriculture. However, the influence of long‐term P addition on the evolution of soil P fertility and legacy P characteristics have not been well‐documented. Herein, literature data were collected from the Chinese National Knowledge Infrastructure Database (CNKI) to explore the evolution of soil P fertility after 33 years of application of P fertilizer; different soil samples were collected from cropland and adjacent uncultivated land to analyse the distribution of P fractions at different soil depths (0–0.8 m) using Guppy's sequential P extraction method. We found that soil Olsen‐P significantly increased by 3.6‐fold (from 7.2 mg kg−1 in 1981 to 25.9 mg kg−1 in 2013) after 33 years of P application, while total P increased slightly. The ratios of inorganic P fractions in cropland to those uncultivated land followed NaHCO3‐P (1.47) > NaOH‐P (1.38) > resin‐P (1.37) > residue‐P (1.17) > HCl‐P (1.11), suggesting that long‐term P addition contributed more to labile and moderately labile P rather than non‐labile P. Moreover, a principal component analysis could distinguish between cropland and uncultivated land, indicating that long‐term application of P fertilizer changed soil P characteristics. Compared to uncultivated land, soil NaHCO3‐P in cropland was closely associated with soil organic C, total nitrogen and carbonate. Collectively, our findings highlight that soil legacy P was notably increased after long‐term of P application, and a large portion of the applied P remained in labile and moderately labile forms. Therefore, soil legacy P can be recommended as a useful P management tool.

“…Many previous studies reported that the characteristics and the application strategies of P fertilizers have a considerable impact on P availability and mobility in soils, and further on crops growth and nutrient uptake (Y. J. Gao et al., 2018; Kang et al., 2021; Lombi et al., 2004). It is generally known that P application increases the initial P concentration in the soil solution.…”

“…However, due to precipitation processes, P concentration drops rapidly during the growing season (Soltangheisi et al., 2018). On the other side, P application through high‐frequent drip fertigation systems can considerably minimize the exposure time of the added P fertilizer in the soil, reducing P precipitation and increasing its availability for plants (Kang et al., 2021; Mohammad et al., 2004). The interaction between P fertilizer forms, P application rate and frequency, and irrigation water properties may have a great impact on dripper clogging and the effectiveness of the drip irrigation system (Li et al., 2019).…”

Background Phosphorus (P) fertilizer properties and nutrient management strategies substantially affect soil P availability as well as uptake and consequently crop yield. Aims The present study aims to study the potential use of inorganic soluble polyphosphates (Poly‐P) as slow‐release fertilizer under drip fertigation. Methods A pot experiment was conducted using an alkaline soil. Two Poly‐P fertilizers, differing in their polymerization rate (Poly‐53 with 53% and Poly‐100 with 100% Poly‐P of the total‐P content), were compared to an orthophosphate (Ortho‐P) and a treatment without P application (control) under three drip fertigation frequencies (Fsow: P fertilizer applied at sowing, Fweek: once a week, and F3days: every 3 days). Soil samples were taken at 40 days after sowing and at harvest from 3 layers (0–5, 5–10, and 10–20 cm) to determine P availability in soil (Olsen‐P) and its relocation into deeper soil layers. Furthermore, plant growth, yield, P uptake, P use efficiency, as well as water productivity were investigated. Results Soil P availability varied significantly between fertilizer forms and fertigation frequencies. At higher polymerization rate of the Poly‐P fertilizer, P becomes less mobile in the soil, but its availability is maintained until harvest. The analysis of Olsen‐P at harvest showed that the higher P availability in soil was obtained with Poly‐P forms with higher values in the 0–5 and 5–10 cm soil layers than in the 10–20 cm. In addition, weekly fertigation (Fweek) revealed the best results in terms of P availability compared to other P fertigation regimes, and all P fertilizers significantly improved chickpea grain yield, seed quality, and water productivity, compared to the unfertilized control. Conclusion Poly‐P fertilizers can be recommended as an effective source of phosphorus for plants, due to their slow‐release properties. Using Poly‐P, the frequency of P application through the drip fertigation system can be reduced while ensuring high crop yields.
