| Esta publicação oferece informações básicas para a construção de uma Semeadeira-adubadeira Manual de baixo custo. O equipamento pode ser feito com madeira, canoss de ferro e de PVC, e materiais descartáveis como garrafas de plástico, pneus e câmaras de ar de automóveis e bicicleta. Trata-se de uma máquina simples, sem engrenagens, leve e de fácil operação, podendo ser construída na propriedade, por aqueles agricultores que possuírem ferramentas básicas de carpintaria. A Semeadeira-adubadeira Manual pode ser usada no plantio de diversas culturas como arroz, feijão, trigo, milho, hortaliças, adubos verdes e capins, na distribuição de adubos granulados em cobertura e no plantio de duas culturas em uma única operação. Manejada como um carrinho de mão, a... |

| Internet auction platforms are changing the face of transactions in many business sectors, including agriculture. We provide one of the first systematic examinations of the differences between internet and in-person auctions in agricultural input markets. A hedonic model estimated with used tractor transactions from Midwestern sellers pooled between eBay and in-person auctions reveals statistically distinct price surfaces for the two auction venues and predicts significantly lower prices for comparable equipment sold on eBay, though this difference is attenuated for tractors fully covered by eBay's buyer protection program and is fully absent for the most frequently traded tractor. An endogenous venue-selection model reveals that larger, more-valuable... |

| Citrus plants are the most important fruit species in the world, with emphasis to oranges, mandarins and lemons. In Rio Grande do Sul, Brazil, most fruit production is found on small properties under organic cultivation. Soil compaction is one of the factors limiting production and due to the fixed row placement of this crop, compaction can arise in various manners in the interrows of the orchard. The aim of this study was to evaluate soil physical properties and water infiltration capacity in response to interrow management in an orchard of mandarin (Citrus deliciosa Tenore 'Montenegrina') under organic cultivation. Interrow management was performed through harrowing, logs in em "V", mowing, and cutting/knocking down plants with a knife roller. Soil... |
