Forage yields were higher the first year of harvest after heavy initial broadcast applications of P than after smaller broadcast or topdressed applications. In following years, yields after the initial application only became progressively poorer, as compared to yields after smaller annual topdressings. Time of application affected yields much more than method of application or source of P. |
