Specifically, in cluster 3 the amount of debt payments in the organic farms is double than in conventional farms, situation that highlight a well-established structure. A significant difference in intermediate costs can be found only in cluster 3, where the level for organic farms is almost twice than that for conventional farms. The differences in other categories and clusters are not significant. Net income, expressed as a percent of sales, is quite similar between organic and conventional farms within a cluster, even though they do differ between clusters.

S. total, the share is much higher for the fruit, vegetable, and dairy sectors. S. organic farm sector expands, university-based research and technical assistance and other State and federal support for organic farmers are also beginning to emerge. 1. INTRODUCTION Farmers have been developing organic farming systems in the United States for over half a century, and organic markets have emerged and expanded greatly during this period. S. Department of Agriculture (USDA) implemented national organic standards on organic production and processing in October 2002, following more than a decade of development, and the new uniform standards are expected to facilitate further growth in the organic farm sector.
