Assess the effect of well water quality on trickle distribution and emitter clogging. Well water was treated by using aeration, chlorination, and phosphoric acid to study effects on soil pH and on emitter plugging. The 90 cbs treatment was converted to a drier evaporation tub strategy. The double tape operated less often, but applied more water. Treatments using a 1-in.
Some emitters continue to plug and lines are replaced about every two seasons.
Berry yields in 1994 and 1995 were similar for all treatments. Yields in 1996 were less than in previous years, but yields were similar for all irrigated treatments with dry land plots producing lower yields than irrigated plots. 1997 Regents of the University of Minnesota.
