A review of research conducted at OSU to determine compost value as a mulch or soil amendment for blueberry produced under conventional, transitional, or organic production systems.
Petroleum mulch applied on the soil surface over a row of
planted seeds promotes a more rapid and a more uniform germination
of seeds, enhances elongation of seedlings and in some cases increases
the yield of the crop. The beneficial effects of petroleum
mulch have usually been attributed to increased...
Cereal residues suppress the development of small seeded, summer annual weeds. The focus of this study was to determine whether cereal residues can be used to suppress weeds in cucumber production systems in the Pacific Northwest. In the first of three experiments, cereal residues of fall-planted, spring-killed cover crops suppressed...
A living mulch system consists of growing a regulated cover crop
with an economic crop. Living mulches are often interplanted with
horticultural crops, but competition for water can adversely affect
crop production. Various management practices may limit the negative
effects.
Studies were conducted for two purposes: (1) to determine if...
Two experiments were conducted on wine grapes 'Chardonnay' and
'Gewurtztraminer' (Vitis vinifera L.) in 1986 and 1987 to
investigate the performance of grapes in competition with perennial
ryegrass (Lolium perenne L.) 'Manhattan 11' sod, the competition
between sod and grapes for nutrients and moisture and the effects
of nitrogen fertilization...
Crops were planted into tilled strips in an established perennial ryegrass
(Lolium perenne L. 'Manhattan II'), sod covering various portions (55%, 66%,
77%) of the row width. Italian beans (Phaseolus vulgaris L. 'Romano II')
biomass and yields showed a trend among sod strips with lower yields
produced in plots with...
Compost is not only an excellent mulch but also a good fertilizer and soil conditioner when you work it into the soil. When properly made, it will be free of viable weed seeds.
