Abstract:
Soil management practices and fertilizer recommendations for peat and muck soils in Klamath and Lake counties are distinctly different than for
mineral soils. High levels of salts and boron have been a problem on
many lower Klamath Lake soils and organic soils in Lake and Harney counties. Surface application of water, by flooding or sprinklers, followed by pumping water out of drain ditches, has reduced salt problems on most fields. However, growers who irrigate by filling drain ditches and
letting water “sub” to the surface move the salts back to the soil surface.
