Organic farmers make system-level crop protection decisions that combine complementary insect, disease, nematode, and weed management strategies. Data from a national survey of U.S. organic farmers were used in a multivariate count data model to identify the farm and regional factors influencing adoption across the linked pest management categories. The results showed that weed management requi...

In order to assess the technical and economic efficiency of conventional farm businesses a variety of management techniques have been developed. These include gross and net margin analysis and full cost accounting. This paper reviews their effectiveness in organic farming systems and finds that all of the techniques can be useful in helping to assess the economic efficiency of individual enterp...

The primary purpose of this paper is to examine the factors that influence earned income of organic farmers explicitly incorporating farmer decisions to engage in local selling. The stochastic frontier model identifies role model producers who are the most technically efficient in achieving the maximum output that is feasible with a given set of inputs along with farm and demographic factors th...

The recent empirical literature on economic sustainability of certified export crops shows that certification standards that enhance yields are important for improving farm revenues and farmer welfare. However, limited evidence exists on the impact of organic certification on the adoption of agro-ecological practices. In this study, we use unique farm-level data from Ghana to examine the impact...

The aim of the study was to assess the level of air pollution by volatile organic compounds (VOCs) in a pig fattening house and in its vicinity. Air samples for chromatographic analysis were taken in the fattening house and in the vicinity of the farm. The air quality study shows that the level of organic gaseous pollutants was twice as high in the fattening house as in the atmospheric air. Alm...

the objective of this study was to evaluate the effects of weaning age on dry matter intake (dmi), average daily gain (adg), feed efficiency (fe), feed cost (fc) and benefit index (bi) of holstein calves reared under organic farming system. thirty two holstein calves were divided into two treatments: early weaning (ew) vs. late weaning (lw). calves in the both groups were provided with whole mi...

Events of the 1990s seem to have given the small farm a new lease on life. Organic agriculture offers a means of producing considerable profitability on very small areas even if many small farmers are of necessity only part-time farmers. Opportunities off the farm, however, have enabled owners of small parcels to farm them profitably, or at least sustainably. Urban agriculture is now a respecte...

Based on production guidelines, organic livestock farming has set itself the goal of establishing environmentally friendly production, sustaining animals in good health, realising high animal welfare standards, and producing products of high quality. By striving for these goals, organic livestock farming meets the demands of an increasing number of consumers who are critical of conventional pro...

The present study was to investigate the effect of the transition from conventional to organic dairy farming on the antimicrobial resistant pattern of pathogens in milk. A farm with tie-stall management, with an average herd size of 20 milking cows, was selected based on the owner’s willingness to accept, for at least 6 months, the highly restricted protocol developed in this study. Comparisons...

Th e aim of the research was the comparison of economic feasibility of most common conventional and organic farm production in Slovenia. Th e methodology of an integrated deterministic technologic-economic simulation system KARSIM 1.0 (DSM) application for cost analysis and decision-making support on farms is described in this article. Th e direct simulation model result is an individual conven...
