White pulp soil corn high-yield and efficiency agricultural machinery and agronomy combined optimized fertilization and soil fertility improvement technology patent collection

This dataset is a collection of series patent documents centered on the technical theme of "high-yield and efficiency-enhancing maize production combined with optimized fertilization and soil fertility improvement in Albic soil." It comprises a total of 10 patent applications filed in 2023, all of which share the same core technology—a preparation method for a composite modified spent mushroom substrate biochar adsorbent—and respectively cover its applications in diverse scenarios including agriculture, rice, vegetables, fruit trees, Chinese medicinal materials, other crops, other agricultural products, and food processing.

Spent mushroom substrate biochar, after composite modification, can exhibit excellent adsorption performance and can be effectively used for Albic soil amelioration, soil fertility enhancement, and nutrient regulation. This dataset systematically brings together patent texts of the same core technology across different application directions, which not only reflects the broad application potential of this technology but also provides researchers and patent analysts in the fields of soil improvement, biochar development, and agricultural waste resource utilization with systematic literature references and data support.
