亚洲精细农业与计算机农业应用联合大会

作者： Martín M. Acebedo Vaz Samuel Túnez Fernando Bienvenido University of Almería Dept. Computer Languages and Sciences Almería Spain

integrated production is a production systems that accepted freely by farmers, assures the application of good agricultural practices, offering a quality label supported by the Ministry of Agriculture. Implementing this system requires a wide set of IT tools in order to assure its application. In this paper, we discuss shortly main characteristics of IP and the different agents that participate in their implementation, describing briefly the different software systems used.

The use of organic wastes, as an alternative to inorganic fertilizer, can be an important strategy for Brazilian and tropical agriculture. Despite the importance, few field studies have been done for evaluating organic amendments on soybean crops in Brazil. The study aimed to evaluate the residual effects of the organic amendments poultry litter, farmyard manure and biochar combined with mineral fertilizer on some agronomic attributes of a soybean crop. A field experiment was carried out in a split-split-plot scheme, with three replicates in a randomized block experimental design. The organic sources (plots) at rates of 0, 3, 6 and 9 Mg·ha-1 (subplots) combined with 0, 100, 200, 300 and 400 kg·ha-1 (sub subplots) of a mineral fertilizer were applied in 2008. In 2009, only the mineral fertilizer was used on the soybean crop. As a?result, all evaluated attributes were influenced by the treatments, except for the number of grains per pod. The application of poultry litter provided the highest yield (3715 kg·ha-1 using 9 Mg·ha-1 of the source). A synergistic effect between organic amendments and mineral fertilizer was observed. It was found the possibility of decrease doses of mineral fertilizers by prior use of organic amendments. The most effective dose combination application is 5.5 Mg·ha-1 of organic amendments associated with 200 kg·ha-1 of mineral fertilizer to provide optimum yield. The use of organic amendments, rich in nutrients, is a technology to sustainably increase the soybean grain yield.

Progress in the technology of energy conversion from woody biomass in Indonesia

Forestry Studies in China 2006年第3期8卷 1-8页

Sustainable and renewable natural resources as biomass that contains carbon and hydrogen elements can be a potential raw materials for energy conversion. In Indonesia, they comprise variable-sized wood from forests （i.e. natural forests, plantations and community forests that commonly produce small-diameter logs used as firewood by local people）, woody residues from logging and wood industries, oil-palm shell waste from crude palm oil factories, coconut shell wastes from coconut plantations, traditional markets as well as skimmed coconut oil and straws from rice cultivation. Four kinds of energy-conversion technologies have been empirically tested in Indonesia. First, gasification of rubber wood from unproductive rubber trees to generate heat energy for the drying of fermented chocolate seeds. Secondly, energy conversion from organic vegetable waste by implementing thermophylic fermentation methods that produce biogas as a fuel and for generating electricity and also concurrently generate organic by-products called hygen compost. Thirdly, gasification of charcoal and wood sawdust for electricity generation. Finally, environment-friendly energy conversion by carbonizing small-diameter logs, sawdust, wood slabs and coconut shells into charcoal. This yielded charcoal integrated with wood vinegar production through condensation of smoke/vapors emitted during carbonization, thereby mitigating the impact of air pollution. Among the four experimental technologies that of integrated charcoal and wood vinegar production had been spectacularly developed and favored by rural communities. This technology brought added value to the process and product due to the wood vinegar, useful as bio-pesticide, plant-growth hormone and organic fertilizer. Such integrated and environment-friendly production, therefore, should be sustained, because Indonesia occupies a significant and worldwide position as charcoal-producing and marketing country. The technology of integrated wood vinegar-charcoal production hence deserves its disse
