In reneral the nitrate cf soda proved much more effective thsrn the bern- yard manure end cost considerably less.

Although it is usually thoueht thet sour plants do best on &cid soils, and thet their lururient frrowth is an indicetion of acidity, it was found by this station "thet rhuberb, @ vryv acid nitnt, is decidedly benefitted by lime, thougn not in such 2 merked derree «xs onions, beets, spinsch and mony other vlents".
