Special Issue Information

Dear Colleagues,

Phosphorus (P) underpins global food systems by ensuring soil fertility, maximizing crop yields, and supporting farmer livelihoods and ultimately food security. Historical P fertilization plays an important role in ensuring crop yield, but low P use efficacy (PUE) usually results in overuse of P fertilizer. This leads to chronic high-cost inputs and has adverse impacts on the environment. This issue focuses on improving P use efficiency and sustainability as well as mitigating P losses across agricultural systems. It aims to bridge fundamental soil processes with practical management strategies to optimize the P cycle.

We highlight innovations such as carbon sources, enhanced-efficiency P fertilizers, biostimulants, bio-inoculants that improve plant P acquisition, breeding crops for higher PUE, and soil amendments to safeguard against P leaching and runoff losses. We welcome interdisciplinary contributions (e.g., soil science, agronomy, plant physiology, environmental engineering) on novel approaches for P management. Studies on economic and policy dimensions, life-cycle assessments, and reviews are also encouraged. All article types are invited.

Carbon (C) is crucial for nutrient cycling and the assembly of microbial populations in the soil. However, it is still unclear how the C-source utilization characteristics of microbes in distinct types of soils respond to changes in soil phosphorus (P) activity. This study investigated how the addition of different C sources with different decomposition rates (glucose, hemicellulose, and lignin) affects P transformation in two distinct agricultural soils (i.e., Mollisols and Fluvo-aquic soil). Results revealed that the short-term glucose addition to soil induced rapid acidification and microbial biomass accumulation, thereby significantly increasing labile P (NaHCO3-Pi, NaOH-Po) content in Fluvo-aquic soil. Lignin amendment promoted gradual HCl-P release in Mollisols, reflecting differential microbial utilization strategies. Glucose stimulated phosphatase activity (2.5–3.0× control) and phoD gene abundance (4.8×) in Fluvo-aquic soil in the early stage, favoring the growth of Pseudomonas and Burkholderia, whereas lignin sustained the mineralization of fungal-associated P in Mollisols (1.8–2.3× phosphatase activity) by enhancing the abundance of Streptomyces and Bradyrhizobium. Soil type dictated P mobilization efficiency. The Fluvo-aquic soil exhibited rapid but transient P release via bacterial dominance, while Mollisols retained slower yet persistent P availability through specialized microbial consortia. Notably, glucose enhanced organic P mineralization by stimulating C decomposition by microbes, particularly in C-rich Mollisols. Lignin increased P availability in Mollisols via Fe/Al-P desorption. However, in Fluvo-aquic soil, lignin reduced the availability of P through microbial immobilization. These findings highlight that C source degradability and soil properties interactively govern microbial-mediated P cycling in soil. Therefore, organic amendments in contrasting agroecosystems need to be optimized. Full article
