12 S ILSOLARIZATIONPSAWEEDMANAGEMENTTOOL IN NEW ENGLAND M.J.Eisel ABSTRACT Soi solarizationmayfit intoa few specific"niches"in crop productionin New England,despite the facttha our soiltemperaturesandsunlightlevelsaregenerallylower thanthoseinthe partsof the world in w ichsolarizationisregularlypracticed.Experimentswere conductedover a five-year periodto terminethe suitabilityof soilsolarizationasatool for weed managementin Massach tts. Maximumsoiltemperaturerecordedata O.S-inchdepthwas 142F,at one inch 127 F,at two in s 12SF,andatthree inchesI 18F.Weed seedlingemergencefrom soilstakenfrom solarizedpi varied,butwassignificantlylowerthanin non-solarizedplotsin allbutone experiment. Thisred on in emergencewasfoundto persisto the followingspring.Someweed emergence occurred, ever, in nearlyallsamplestakenfrom solarizedsoil.Inhibitionof shootgrowthof Canadathi e {O'rsiumarvense(L)Scop.)wasfoundinonetrial, but plot areaswere quickly reinvaded y rhizomesfrom outsidethe plot areathe followingseason.Solarizationhaspotentialto reduce d emergencefrom the top layerof soil,but isnot likelyto reliablyproducethe control ratesneed d to avoidcrop lossesdueto weed interference.However,soilsolarizationmaybe useful in reducingseedbanksor in servingasanadjuncto otherweed managementmethodsfor growers with weed roblemswhicharedifficulto controlin otherways.
