Abstract
We prove that several Feigin-Odesskii Poisson brackets associated with normal elliptic curves in are compatible if and only if they are contained in a scroll or in a Veronese surface in (with an exception of one case when ). In the case we determine the quartic corresponding to the Schouten bracket of two (non-compatible) Poisson brackets associated with normal elliptic curves and .
