In this project, we finished Texas longhorn beef cattle on the Sunshine Farm by using polywire (temporary electric fence) to break-feed crop residues and forages in a narrow strip cropping system without supplemental feed. To close the nutrient cycle between cattle and crops, the project was recommended February 1995 by the seven-member Farmer Advisory Committee for the Sunshine Farm.
A one-year project grant to Practical Farmers of Iowa to research livestock gastrointestinal parasite management resulted in a five-year series of experiments during which attention shifted from commercial botanical mixtures to single-ingredient botanical materials. The end of this period sees renewed interest in the role of management, as results of natural anthelmintics have been variable at best and largely disappointing. Our research results have also pointed to difficulties of collecting reliable data from these on-farm trials.
A. To identify organic farming systems that will benefit from the introduction of brassicas. B. To gather farmer input on the practical concerns regarding incorporating forage brassicas into their grazing and cropping practices. C. To evaluate the effects of brassicas on soil nutrients and subsequent nutrient uptake by crops.
1. Determine the differences in CLA content of organic beef produced by cattle that are grass-finished with minimal grain to that from cattle that are conventionally grainfinished. 2. Determine the time required for cattle to grade at least low choice when finished by the two finishing systems. 3. Determine the economic differences between the two finishing systems. 4. Determine the profitability of marketing grass-finished cattle through Organic ValleyCROPP. 5. Determine eating quality of beef produced by the two finishing systems.
-Analyze several animal manure-based, organic-approved compost products for suppression of important soil-borne pathogens of vegetable crops in the Northeast -Determine applicability of a farmer-based test kit for assessment of compost maturity to predict suppressiveness -Evaluate compost effects on plant stand and crop composition -Determine changes in microbial activity, disease suppressiveness and soil nitrate nitrogen of organically managed soils after addition of a compost
Basil fusarium wilt is a seed-borne disease that can severely reduce basil yields. The biggest concern, however, is that the pathogen can persist in the soil for ten or more years preventing the future use of the land for basil production. The objective of this study was to develop organic control methods that would allow production in infested soil. Several organic mulches, a biocontrol product (Rootshield), and lime applications were examined on soil intentionally infested with fusarium. Basil plants mulched with a composted pine bark had the lowest incidence of fusarium wilt.
The objectives of this research were to: 1) Evaluate susceptibility to early blight in 16 heirloom and modern hybrid cultivars. 2) Evaluate whether disease incidence and severity are reduced on a susceptible tomato variety intercropped with a resistant variety, compared to a monoculture of the susceptible variety.
