INNOVATE | MITIGATE | SUSTAIN
These unique soil types, prevalent in old, weathered landscapes, tropical and subtropical regions, as well as in young soils derived from volcanic ash, demonstrate fascinating properties that influence soil productivity, nutrient and pollutant behaviour, and require their management strategies in both agricultural and environmental contexts.
Our conference aims to bring together researchers, soil scientists, engineers, developers, policymakers, and land managers from around the globe to share insights, discuss challenges, and develop innovative solutions for sustainable soil management.
Themes We’re Covering at the conference
Pedogenesis and Distribution
Chemistry and Mineralogy
Nutrient Interactions in Variable Charge Soils
Agronomic Practices and Nutrient Management: Soils with variable charge: agronomic and fertility aspects
Soil Physical Properties, Water Management and Hydrological Dynamics
Contaminant Interactions and Risk Management
Slope Instability

OCP Group
This partnership with crcCARE underscores OCP Group’s longstanding engagement with the global scientific community. It reflects our dedication to contributing to the development of evidence-based solutions that foster both agricultural productivity and sustainability. This partnership provides an invaluable platform to contribute to high-level scientific dialogue, to share and to gain access to new insights, and to collaborate with leading experts and institutions in the field of soil science.
We deeply value the scientific and strategic significance of this conference, particularly given the critical role that variable charge soils play in tropical and subtropical agriculture. The exploration of fertilizer–soil interactions, nutrient dynamics, and environmental risk mitigation aligns closely with OCP Group’s commitment to advancing sustainable agriculture practices and promoting soil health across diverse geographies globally, particularly in Africa.
We are particularly honoured to deliver opening remarks and to associate OCP Group’s name with the conference’s core objectives and its commitment to scientific integrity. We also appreciate the additional visibility and engagement opportunities afforded by the Titanium sponsorship package.
