This dataset integrates experimental data from three research papers published in the international journal Plant and Soil (2024), the Chinese core journal Chinese Journal of Applied Ecology (2024), and Nutrient Cycling in Agroecosystems (2025). These three studies all focus on the enhanced rock weathering (ERW) technology through the field application of silicate mineral (wollastonite) powder, and were conducted as field-controlled trials lasting one growing season (approximately 5 months) in typical paddy fields and soybean fields in Northeast China (Liaoning Province). The core parameters of the dataset include: grain and straw yields of rice/soybean; yield components (e.g., tiller number, grain number per panicle); grain quality indicators (protein, starch, sugar content); silicon (Si), calcium (Ca), and magnesium (Mg) contents in plants and soils; soil physicochemical properties (pH, available silicon, exchangeable Ca/Mg, microbial biomass carbon and nitrogen); soil carbon fractions (total carbon, organic carbon, inorganic carbon, dissolved carbon, phytolith occluded carbon); and the accumulation of toxic trace elements (arsenic, cadmium) in edible parts (grain) and non-edible parts (straw) of crops. The data were derived from standardized measurements of control and treatment plots under different wollastonite application gradients (0, 2.5, 5, 10 t ha⁻¹), and are presented in the form of numerical tables, figures, and statistical analysis results (means, standard errors, significance tests). Data precision is ensured through replicated sampling (n = 4) and standardized laboratory analytical methods. This dataset covers the production systems of major crops (rice and soybean) in Northeast China, and systematically reveals the multiple effects of low-to-moderate dose (5 t ha⁻¹) wollastonite application on crop yield increase, soil improvement, carbon dioxide sequestration (aboveground phytolith occluded carbon and belowground soil inorganic carbon), and agricultural product safety (heavy metal inhibition). It provides comprehensive and critical empirical data support for evaluating the agronomic feasibility, ecological benefits, and environmental risks of ERW technology in this region.
