Abstract(s)
Foi realizada a caracterização do parque de máquinas e a sua utilização no plano cultural, no ano agrícola de 2008/2009, na Sociedade Agrícola do Rabaço, Lda., cuja exploração agrícola se situa no concelho de Avis (Alto Alentejo).
Verificou-se que face ao plano cultural de 2008/2009, e que se perspectiva que venha a ser o mesmo nos próximos anos, o parque de máquinas está sobredimensionado, contando com uma frota de 3 tractores de grande potência (150 cv, 130 cv e 105 cv) que, no conjunto, trabalham apenas cerca de 1080
horas/ano, o que é manifestamente pouco. A consequência directa desta situação é existirem custos horários de utilização dos tractores muito elevados (entre 32 e 43 €/h), que agravam as contas da exploração.
No sentido de optimizar a utilização deste parque de máquinas, em particular da frota de tractores, estudaram-se 3 soluções alternativas: adaptar o plano cultural ao parque de máquinas; prestar serviços de mecanização ao exterior; alterar o parque de máquinas. Verificou-se não ser viável adaptar o plano cultural da exploração ao parque de máquinas existente para incrementar o uso da maquinaria da exploração. As outras duas soluções revelaram-se economicamente interessantes, pois permitiram reduzir custos horários de
utilização dos tractores. Prestando serviço de mecanização ao exterior, a economia anual em custos de utilização dos tractores, para cumprir o plano cultural, cifra-se em 10.309,10 €/ano. Alterando o parque de máquinas, para enveredar pela mobilização de conservação, a economia cifra-se, para o mesmo plano cultural, em 21.220,60 €/ano. A solução que se afigura como a mais vantajosa é, sem dúvida, a prestação de serviços de mecanização ao exterior, pois para além de reduzir custos na exploração, passa-se a ter uma receita adicional de 129.080 € pelos trabalhos realizados.
Concerning the agricultural year of 2008/2009, a description has been made of both the machinery and its use within the cultural schedule at Sociedade Agrícola do Rabaço, Lda. (its farmland is situated in the region of Avis – Alto Alentejo). The analysis showed that according to the cultural schedule for 2008/2009, which is thought that it will become similar in the following years, the existing machinery is clearly surpassing the need as the three powerful tractors (150 h.p., 130 h.p., 105 h.p.) are operating about 1080 hours/year together, which is in fact, a lower production level than expected. As a consequence, production costs are rapidly increasing due to the high prices of the operating tractors (from 32€/h to 43€/h). In order to make all the farm machinery profitable, particularly the three tractors, three alternative options were suggested: - adapting the cultural schedule to the existing machinery; - doing farm work outside the farmland using its machinery and getting a payment for that; - modifying the existing machinery. The first option is not economically viable when using the farm machinery. However, the two other options turned out to be economically positive, as it was cheaper using the tractors. By operating in other farms, the total amount of savings is 10.309,10€/year when following the cultural schedule. By modifying the existing machinery, the total amount of savings is 21.220,60 €/year. The option which clearly would bring more advantages is operating in other farms, as it not only reduces production costs, but it also provides an additional revenue of 129.080 €.
