 WELCOME LETTER OPW2023

We cordially invite you to participate in the 2023 Organic Phosphorus Workshop entitled
“Exploring the fate of organic phosphorus in soil and aquatic ecosystems in relation to global
societal and environmental challenges”.

Humanity faces many urgent challenges, including food security, environmental degradation, and climate change. The maintenance of current global food production, as well as future increases driven by projected population growth, are strongly dependent on continued inputs of phosphorus, mainly in the form of mineral fertilizers derived from phosphate rock. Global phosphate rock resources are finite, and there is an acknowledged urgent need to improve phosphorus use and efficiency in agroecosystems to meet increasing demand. Organic forms of phosphorus account for up to half of the total phosphorus present in many agricultural soils. The nature and dynamics of organic phosphorus in soil play a major role in determining phosphorus bioavailability and plant productivity, and optimisation of biological phosphorus cycling has the potential to contribute significantly to improving phosphorus use efficiency. Long-term inputs of phosphorus have resulted in the accumulation of significant quantities of legacy phosphorus in agricultural soils which in turn has contributed to increased diffuse phosphorus transfer and accelerated eutrophication of many water bodies. Biological processes play a vital role in determining the mobility and bioavailability of phosphorus in soils and sediments.

The workshop will be held in Pucón, Chile between 27th November and 1rst December 2023.
This is the fourth iteration of the organic phosphorus workshop series, and previous meetings were held in Switzerland (2003), Panama (2013), and England (2016).

We look forward to your participation in OP 2023!

Role and function of soil organic phosphorus in sustainable land management.
The role and function of organic phosphorus in soil in sustainable land management is crucial, as this essential nutrient helps maintain fertility, structure, and water and nutrient retention capacity in the soil. In addition, its adequate availability is crucial for the growth and development of plants, influencing agricultural productivity and biodiversity conservation.
Soil organic phosphorus is important for soil fertility and phosphorus loss to water. Organic phosphorus is present in organic matter, which originates from microbial degradation of animal and plant residues. In various soils, it can represent up to 50% of the total insoluble phosphorus. Better understanding of the mechanisms involved in its mobilization is needed to achieve sustainable phosphorus management.
Nature and biogeochemistry of organic phosphorus in water and sediments

The nature and biogeochemistry of organic phosphorus in water and sediments encompass the study of its origin, cycle, and chemical transformations in aquatic environments. These processes influence water quality, nutrient availability, and the maintenance of aquatic life, being of great importance for the conservation of ecosystems and sustainable use of water resources.

Interactions between the biogeochemistry of organic phosphorus and other elements in terrestrial and aquatic ecosystems.

The interactions between the biogeochemistry of organic phosphorus and other elements in terrestrial and aquatic ecosystems are complex and multifaceted. These interactions affect the balance and functioning of ecosystems, influencing biodiversity, productivity, and the resilience of these systems to disturbances. Thus, understanding these interactions is key to the sustainable management of ecosystems and natural resources.

Impacts of climate change on organic phosphorus dynamics in soil and aquatic ecosystems

The impacts of climate change on the dynamics of organic phosphorus in soils and aquatic ecosystems can be diverse, including alterations in nutrient cycling, phosphorus availability and mobility, and the balance between organic matter production and decomposition processes. These changes can affect ecosystem health, agricultural productivity, and the capacity of ecosystems to sequester carbon, among other aspects.

Advances in methodology to investigate and quantify organic phosphorus dynamics.

Advances in methodology for investigating and quantifying the dynamics of organic phosphorus have allowed for a better understanding of its cycle and role in the environment, facilitating the adoption of sustainable practices in resource management. These advances include the development of more precise and sensitive analytical techniques, as well as the application of interdisciplinary approaches and numerical models that integrate various aspects of the biogeochemistry of organic phosphorus.

Interaction between biotic and abiotic phosphorus dynamics in soils and sediments

New insights into understanding the relationship between biotic and abiotic processes affecting the dynamic of phosphorus cycling, including the transformation, accumulation, immobilization, solubilization, desorption, mineralization, and uptake of this element in soil and sediments. The understanding of the biotic and abiotic process governing the phosphorus dynamic is pivotal for its management in soils and its impact on the ecosystem.

Special Issue

On the occasion of the incoming “Organic Phosphorus Meeting 2023 (OP2023)”, which will be held from November 27 – December 1 in Pucón (Chile), we are glad to inform you that the editorial board of The Journal of Soil Science and Plant Nutrition (JSSPN; https://www.springer.com/journal/42729) is planning to do a special issue.

The purpose of the special issue is to publish high-quality reviews and/or original papers on hot topics in the field of organic phosphorus fate in soil ecosystems under the climate change and food security scenario. In addition, authors who have presented their work at OP2023 may submit their manuscripts to the journal.
