Bibliometric and correlation visualization analysis were carried out to clarifies the current innovation status and the future trend of acid soil conditioner industry. The database includes 300 patents, 158 products and related institution, raw material information etc., and established from Derwent patent database and registered product in the Ministry of Agriculture and Rural Affairs. Results show that the number of granted patents and registered products has increased rapidly since 2014, universities and enterprises are dominating in acid soil conditioner patents, accounting for 32.7% and 67.3% respectively. As from the perspective of composition, only 23.4% of the registered products consist more than 3 kinds of materials, and mainly produced from mineral resources, industrial and agricultural wastes, with a frequency of 96.2% for minerals. While, the granted patents show great diversification in composition, 66.3% of the patents contain more than 5 kinds of materials and matching with 2-3 kinds of process technologies. Moreover, the frequency of polymer materials and microbial bacterium are obvious increased in granted patents. The dosage forms are mainly powders in granted patents and in registered products, but the proportion of granular products shows a clearly increasing trend. As from the function perspective, the patents innovation of acid soil conditioners prefers the combination of soil acidity regulation, nutrient supplementation and structural improvement, while registered products focus more on soil acidity neutralization and waste resource re-utilization. Therefore, we suggest to strengthen the transformation from patents into products and encourage the development of granular, multi-functional acid soil conditioner to promote the sustainable utilization of acidic arable land in China.
