2026-08-29 Compilation of Extension and Application Proofs for Optimized Fertilization and Soil Fertility Enhancement Technologies for Albic Soil Maize Production Integrating Agronomy and Mechanization doi:10.57760/sciencedb.iga.001aq en This dataset is a collection of demonstration and application certificates for the "High-Yield and Efficiency-Enhancing Maize Production Technology on Albic Soil through Integrated Agronomic and Mechanical Optimization of Fertilization and Soil Fertility Improvement," systematically compiling the demonstration and extension area data of this technology system across different regions and years in Heilongjiang Province. The dataset comprises 12 independent DOCX documents, recording the promotion and implementation of this technology among multiple cooperative entities (including Xiayumi Biotechnology Co., Ltd., etc.) during 2022–2025. The cumulative demonstration and extension areas cover multiple batch scales such as 370,000 mu, 350,000 mu, 400,000 mu, 300,000 mu, and 270,000 mu, as well as large-scale application data of 1.256 million mu, 1.062 million mu, and 242,000 mu completed in 2024 and 2025, respectively. Each document serves as a corresponding data description file, featuring standardized content and detailed records, which can directly reflect the actual effectiveness of this technology system from experimental demonstration to large-scale promotion and application. The dataset is suitable for technology extension effect evaluation, agricultural science and technology achievement transformation analysis, and research on the radiation scope of Albic soil improvement technologies.
