Quality status analyses of our country's monoammonium phosphate and diammonium phosphate

By summarizing the results of national supervision of monoammonium phosphate and diammonium phosphate,we analyses quality status of these fertilizers in our country.We know through the article that the quality of these two kinds fertilizers are better compared to the other ones.But as the decreasing of the amount of the phosphate resources,manufactures can not change suitable phosphate resources,it become more difficult to control the quality of these two kinds fertilizers.Farmers seldom apply these two kinds fertilizers recently,lots of them are used to produce compound-fertilizer.So we should extend the application techniques of them.
