Synopsis
Potash was the most important factor in maintaining high yields and persistence of an alfalfa stand. The “critical percentage” for potassium content varied from season to season and probably lies somewhere between 1.42 and 1.84%. Nitrogen fertilization tended to decrease yields and stands whereas phosphorus had no significant beneficial effect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
