8804. Painter, K.M.. 1990. Does sustainable farming pay: a case study.. paper presented at Amer. Agr. Econ. Assoc. meetings, Vancouver, B.C., Aug. 4-8, 1990.
A wheat farm in eastern WA using green manure, minimal pesticide, and no commercial fertilizer for over 75 years, earned net returns averaging 25% lower than a typical conventional rotation for the area. Planting Austrian winter peas and grass cost $58 and $65 an acre, respectively, compared to $27 an acre for summer fallow. Fertilizer savings of $23 an acre were largely offset by these additional expenses. The choice of dry peas in the system results in fairly high chemical cost. When market prices were low, returns for the Lambert farm were 5% higher than for a conventional system, without support payments. The conventional system was some 30% more profitable with high prices, with or without support payments. Government payments increased net returns considerably more on the conventional farm, supporting the argument that programs encourage conventional high input systems. This study demonstrates that environmental and economic sustainability are not necessarily compatible.

Zane Zell of Shelby, Montana has grown as many as 1000 acres with no purchased chemicals, and only 12" annual rainfall, while producing the same average yields as conventional farmers. Zell says the key to his fertility is the Austrian winter pea green manure crop he grows. Besides fuel, the only other purchased input he uses is rock phosphate, about every four or five years. Weed control is achieved by timely field preparation with a plow and a rod weeder. Because of the growing demand for organically grown food, Zell is sold out a month after harvest. By turning his wheat grain into flour and cleaning and bagging his speciality legumes, he is able to increase his profits by up to 350%.
10059. Smith, L.J.. 1988. Regenerative agricultural systems in Nez Perce county.. unpublished handout, Univ. of Idaho/Nez Perce Cooperative Extension, Lewiston, ID.
This study was undertaken to evaluate, demonstrate and compare the competitive advantages associated with the use of green manure plowdown as a viable segment of regenerative systems in Nez Perce County. The greatest N return came from the yellow blossom clover and red clover mixture plowdown (191 lbs N), while two Austrian winter pea sites returned 116 and 92 lbs/ac N. Nitrogen carryover indicated that topdress N could have been reduced by 88% under the clover plowdown and up to 100% under one of the pea plowdowns. Yields of soft white winter wheat were 110 bu/ac following clover, and 82 and 100 bu/ac following the two pea plowdowns. Net return following clover was $214.85, and $94.63 and $123.35 for the two pea sites.
10455. Young, D.L. and K.M. Painter. 1990. Farm program impacts on incentives for green manure rotations.. Amer. J. Alter. Agric. 5:99-105.
This study examines the acreage reduction program (ARP) and the deficiency payment effects of the 1985 Farm Bill on the relative profitability of a low-input rotation and a grain-intensive conventional rotation in Washington state over 1986-1990. In years of low deficiency payments or high foregone returns for ARP land, the low-input green manure rotation was competitive with the conventional rotation but lost its advantage in years of low ARP costs or high deficiency payments. Long-run incentives to maintain wheat base introduced a consistent bias against the low-input green manure rotation. This study's findings strongly support strengthening base flexibility in future farm policy legislation. It is crucial, however, that these proposals include soil building green manure crops that can be grown on "flexible" base acres on ARP acres.
