Resumo: | The adoption of precision agriculture techniques finds great limitation because of the high cost, not always guaranteeing the expected economic return. Among the consequence of this elevated cost it is the restriction use of this technology in small farmers, characterized by the family farm. The present work approaches a bibliographical study about the situation of the family farm in Brazil, pointing to regional focuses. In order to complement this study was made a diagnosis on the existing agricultural machines park and the mechanization used intensity in the state of Rio Grande do Sul, aiming a reflection about the role of the agricultural machine industries for small farmers. This work was dedicated to apply precision agriculture techniques in a small farmer where an area of 10,9 hectares was managed with precision agriculture tools and appropriate information technology to the socioeconomic farmer profile. In order to reach this general objective it was proposed the following specific objectives: a) to identify the horizontal spatial variability of the soil attributes through fertility maps; b) to apply fertilizers in different doses for each handling zones; c) to measure soil resistance to penetration and wheat leaf chlorophyll; d) to make yield map; e) to take note of production costs and to elaborate liquid revenue map for wheat culture; f) to evaluate performance of agricultural machines using GPS tracker. As some results, it was found horizontal spatial variability in soil for phosphorus and potassium and chlorophyll in wheat leaf; it was possible to apply different quantities of fertilizer using seeding and centrifugal broadcaster spreaders without automatic variable rate. In this area, the average of wheat yield was 2427 kg.ha-1, changing from 1915 to 3151 kg.ha-1. Considering the relationship between productivity and production costs, the liquid revenue varied from R$ 14,00 to 358,00 per hectare and had average of R$ 183,48 per ha. The individual crossing among digital models evidenced correlation of 48,6% between productivity and liquid revenue. In general way, precision agriculture tools can help the farmer to know better and more precisely each part of area destined to agricultural activity. It allows to increase the production efficiency through a better soil handling and rational use of the inputs, reducing costs, and other times, increasing productivity. |

Entre as conseqüências deste elevado custo está a restrição do uso dessa tecnologia em pequenas propriedades, caracterizadas pela agricultura familiar. O presente trabalho inicialmente aborda um estudo bibliográfico sobre o retrato da situação da agricultura familiar no Brasil e apontando para enfoques regionais. Complementam este estudo um diagnóstico sobre a frota de máquinas agrícolas existente e os índices de mecanização nas diversas regiões do Rio Grande do Sul, levando à reflexão sobre o papel da indústria de máquinas agrícolas para pequenas propriedades. O trabalho foi dedicado à aplicação de técnicas de agricultura de precisão em uma pequena propriedade, onde se preocupou em gerenciar uma área de 10,9 hectares com ferramentas e tecnologia de informação mais adequada ao perfil agrosocioeconômico do produtor. Para atender este proposto, os objetivos específicos foram: a) identificar a variabilidade espacial horizontal dos atributos de solo através de mapas de fertilidade; b) aplicar fertilizantes em diferentes doses por zonas de manejo; c) medir resistência à penetração do solo e clorofila na folha de trigo; d) confeccionar mapa de produtividade; e) apontar os custos de produção e elaborar mapa de receita líquida da cultura do trigo; e f) avaliar o desempenho operacional das máquinas agrícolas através de rastreamento por GPS. Entre os principais resultados, encontrou-se variabilidade horizontal dos teores de fósforo e potássio no solo e de clorofila no trigo; foi possível aplicar diferentes doses de fertilizantes utilizando semeadora e distribuidor centrífugo de taxa fixa. A produtividade média de trigo na área foi de 2427 kg.ha-1, oscilando entre 1915 e 3151 kg.ha-1. Considerando a relação produtividade e custo, a receita líquida variou de R$ 14,00 a 358,00 por hectare e em média R$ 183,48 por ha. O cruzamento individual entre modelos digitais evidenciou correlação de 48,6% entre produtividade e receita líquida. De uma forma geral, as ferramentas de agricultura de precisão podem ajudar ao produtor a conhecer melhor e mais detalhadamente cada parcela de sua área destinada à atividade agrícola, permitindo aumentar a eficiência produtiva através do manejo e do uso racional dos insumos, diminuindo custos, e por vezes, aumentando a produtividade.Universidade Federal de Santa MariaBREngenharia AgrícolaUFSMPrograma de Pós-Graduação em Engenharia AgrícolaSchlosser, José Fernandohttp://lattes.cnpq.br/0575023987760421Reys, Marcos Alves doshttp://lattes.cnpq.br/2660751499634138Alonço, Airton dos Santoshttp://lattes.cnpq.br/9734276321240323Knob, Marcelino João2007-12-122007-12-122006-02-24info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/pdfKNOB, Marcelino João.
