摘要： The present invention provides a process for preparation of a fertilizer, particularly a process for preparation of a nano long-acting selenium fertilizer. The present invention provides a process for preparation of a long-acting selenium fertilizer, including: mixing a selenium rich carbonaceous siliceous rock powder having 30-95% of nano particles relative to total volume and a selenium content of 500 μg/g or more with a liquid having pH of 8.0-10.0. The liquid having pH of 8.0-10.0 is obtained by mixing KOH, K2CO3 and 20% ammonia in a weight ratio of 10:1:2, and then adjusting pH with water.
