** Shares in K+S SDFGn.DE fall around 3% after Stifel
downgrades the German salt and potash miner to "sell" from
"hold", flagging a risk of worsening sentiment post Q1
** The broker expects K+S to report solid Q1 EBITDA and FCF,
but warns the trend could get worse in the coming quarters
** High inventories in China and Brazil could lead to
falling potash prices, with farmers and fertiliser makers
unlikely to accept higher European prices for long, it says
** Stifel sees no reason to expect a tightening potash
market or a price rebound in the coming years either
** Nine out of 21 analysts rate the K+S stock "strong buy"
or "buy", eight "hold" and four "strong sell" or "sell"
