Results of long-term application of fertilizers to flood-plain meadows


, : Results of long-term application of fertilizers to flood-plain meadows. Trudy Novgorodskoi Sel' skokhozyaistvennoi Opytnoi Stantsii (4): 66-75

In trials in 1965-73 with meadows in the flood-plain valley of the Veronda river in Leningrad province, application of 30 and 120 kg N/ha increased average hay yields by 1.42 and 3.56 t/ha, respectively. N was effective in increasing yields during the 1st 2 years and PK when combined with N increased yields during the following years.
