This chapter explores research strategies for evaluating soil remineralizers (REM), emphasizing their nature as insoluble, multi-nutrient sources that release nutrients gradually and in low concentrations. It highlights the importance of biological processes and microorganism interactions, specifically bioweathering processes, in enhancing mineral weathering and increasing REM effectiveness. The chapter discusses the importance of experimental design, ranging from simple chemical extraction systems to complex field trials, in order to accurately assess the REM potential for improving soil fertility and crop nutrition in tropical conditions. It emphasizes the necessity of characterizing REM based on geochemical, mineralogical, and granulometric properties, and tailoring experiments to specific soil types and crop needs. Here, we advocate multi-faceted approaches, considering soil type, crop species, application rates, physical properties, and experiment duration to optimize REM use. It also critically evaluates the limitations of traditional controls in experimental setups, recommending strategies to understand REM's agronomic contributions better. Ultimately, this chapter provides a comprehensive framework to guide future research, aiming to promote sustainable practices through the effective use of silicate mineral-based soil amendments.

摘要

This chapter explores research strategies for evaluating soil remineralizers (REM), emphasizing their nature as insoluble, multi-nutrient sources that release nutrients gradually and in low concentrations. It highlights the importance of biological processes and microorganism interactions, specifically bioweathering processes, in enhancing mineral weathering and increasing REM effectiveness. The chapter discusses the importance of experimental design, ranging from simple chemical extraction systems to complex field trials, in order to accurately assess the REM potential for improving soil fertility and crop nutrition in tropical conditions. It emphasizes the necessity of characterizing REM based on geochemical, mineralogical, and granulometric properties, and tailoring experiments to specific soil types and crop needs. Here, we advocate multi-faceted approaches, considering soil type, crop species, application rates, physical properties, and experiment duration to optimize REM use. It also critically evaluates the limitations of traditional controls in experimental setups, recommending strategies to understand REM's agronomic contributions better. Ultimately, this chapter provides a comprehensive framework to guide future research, aiming to promote sustainable practices through the effective use of silicate mineral-based soil amendments.
