Description
“COMPOSIÇÃO PARA PRODUÇÃO DE MUDAS DE AROEIRA COM APROVEITAMENTO DE LODO DE CURTUME”“COMPOSITION FOR PRODUCTION OF AROEIRA SEEDLINGS WITH THE USE OF CURTUME SLUDGE”
Campo da Invenção [001] A presente invenção refere-se a um processo novo de produção de mudas de aroeira, onde se busca uma proporção ideal entre diferentes misturas de substratos e um elemento novo, que é o resíduo de curtume. Tal resíduo visa a substituição total ou parcial das adubações feitas de forma convencional, de modo a diminuir os custos de produção dos viveiristas, pois tais resíduos são simplesmente descartados no meio ambiente ou mesmo dando outra possibilidade de produção de mudas concorrentes de compostos comerciais.Field of the Invention [001] The present invention relates to a new process for the production of aroeira seedlings, where an ideal ratio between different mixtures of substrates and a new element, which is the tannery residue, is sought. Such residue aims at the total or partial replacement of fertilizers made in a conventional way, in order to reduce the production costs of nurseries, as such residues are simply discarded in the environment or even giving another possibility of producing competing seedlings of commercial compounds.
Fundamentos da Invenção [002] Para se determinar a proporção ideal do lodo de curtume a ser utilizado na propagação de mudas de aroeira, vem sendo estudadas várias misturas de diferentes componentes do substrato juntamente com o lodo de curtume desidratado.Fundamentals of the Invention [002] In order to determine the ideal proportion of the tannery sludge to be used in the propagation of mastic seedlings, several mixtures of different components of the substrate have been studied together with the dehydrated tannery sludge.
[003] Normalmente o substrato para produção de mudas de aroeira é feito através de misturas de substratos como terra, húmus, esterco de gado e substratos comerciais, onde tais substratos são normalmente compostos de casca de arroz carbonizada, pinus, vermiculita ou fibra de casca de coco. A proposta desse novo processo é substituir alguns componentes desses substratos comerciais pelo lodo de curtume desidratado, na proporção certa do substrato, para promover um novo substrato com resultados semelhantes ou melhores do que os substratos convencionais promovem. Para isso, busca-se identificar a melhor proporção do lodo na composição dos substratos, para formulação de um substrato mais simples e barato.[003] Normally the substrate for the production of mastic seedlings is made through mixtures of substrates such as soil, humus, cattle manure and commercial substrates, where such substrates are usually composed of carbonized rice husks, pine, vermiculite or bark fiber. Of coconut. The purpose of this new process is to replace some components of these commercial substrates with dehydrated tannery sludge, in the right proportion of the substrate, to promote a new substrate with similar or better results than conventional substrates do. For this, we seek to identify the best proportion of sludge in the composition of the substrates, for the formulation of a simpler and cheaper substrate.
[004] De acordo com trabalhos já executados, e outros em execução, a proporção ideal de lodo na composição dos substratos, dependem da espécie testada e podem variar desde 1% a 80% do volume de lodo no substrato. No entanto, vários estudos vêm[004] According to works already carried out, and others in progress, the ideal proportion of sludge in the composition of the substrates, depends on the species tested and can vary from 1% to 80% of the volume of sludge in the substrate. However, several studies have

2/6 sendo executados a fim de se identificar uma proporção adequada para cada espécies nesse processo que tornem o processo de produção de mudas viáveis, com mudas de qualidade igual ou superiores as convencionais.2/6 being executed in order to identify an adequate proportion for each species in this process that make the seedling production process viable, with seedlings of equal or superior quality to conventional ones.
Técnica Relacionada [005] Algumas patentes sobre o aproveitamento do resíduo de curtume já foram depositadas e o uso do lodo de curtume não é novidade na agricultura. Porém não foram encontrados documentos relativos a um processo simples de aproveitamento desses resíduos na produção de mudas.Related Technique [005] Some patents on the use of tannery residue have already been filed and the use of tannery sludge is not new in agriculture. However, no documents were found related to a simple process of using these residues in the production of seedlings.
[006] É conhecida, por exemplo, as patentes PI07008801-5A; PI0700915-1A; PI0704583-2A; PI0700771-0A; PI0503277-6A; PI0700772-8A, todas de um mesmo depositante, as quais se referem a criação de um fertilizante composto, de modo que o produto de inovação dos registros são misturas complexas de vários elementos, como sangue bovino, lodos diversos, cinzas, serragem ou casca de madeira, esterco, entre outros elementos de mistura. Tais registros referem-se a um produto final na forma de fertilizante e matéria orgânica, e não se constitui de um composto completo para o plantio das mudas diretamente. As referidas invenções estão limitadas a adição da mistura na forma de adubo para as plantas, diferentemente do processo requerido, o qual constituise da adição somente do lodo de curtume desidratado em mistura com a terra de subsolo para substrato e mudas.[006] It is known, for example, patents PI07008801-5A; PI0700915-1A; PI0704583-2A; PI0700771-0A; PI0503277-6A; PI0700772-8A, all from the same depositor, which refer to the creation of a compound fertilizer, so that the product of innovation of the records are complex mixtures of various elements, such as bovine blood, various sludges, ash, sawdust or bark. wood, manure, among other mixing elements. Such records refer to a final product in the form of fertilizer and organic matter, and do not constitute a complete compound for planting seedlings directly. Said inventions are limited to the addition of the mixture in the form of fertilizer for plants, unlike the required process, which constitutes the addition of only the dehydrated tannery sludge in mixture with the subsoil for substrate and seedlings.
[007] Também é conhecida a patente PI1000015-1A2, a qual trata-se de reciclagem de rejeitos de couro contendo cromo. Esta patente trata da reciclagem do cromo no resíduo e da criação de um adubo alternativo com uso de resíduos de curtume e adição de adubos convencionais. Esta patente se diferencia da requerida, pois não há regeneração do cromo e nem adição de adubos convencionais no lodo para complementação nutricional das plantas.[007] The patent PI1000015-1A2 is also known, which deals with recycling of leather waste containing chromium. This patent addresses the recycling of chromium in the waste and the creation of an alternative fertilizer using tannery residues and the addition of conventional fertilizers. This patent differs from that required, as there is no regeneration of chromium and no addition of conventional fertilizers in the sludge for nutritional supplementation of plants.

[026] No entanto, o resultado que aponta a melhor proporção de lodo de curtume desidratado para ser usado em mudas dessa espécie associado a terra de subsolo, é apresentada com a proporção de 30% de lodo de curtume (T3 desse experimento), a qual foi o único tratamento que apresentou qualidade similar de mudas, apontado pelo índice de qualidade de mudas de Dickson.[026] However, the result that indicates the best proportion of dehydrated tannery sludge to be used in seedlings of this species associated with subsoil, is presented with the proportion of 30% of tannery sludge (T3 of this experiment), the which was the only treatment that presented similar seedling quality, as indicated by Dickson's seedling quality index.
[027] Com isso, conclui-se que o lodo de curtume desidratado pode ser usado como fonte alternativa para a produção de mudas da espécie Schinus terebínthifolíus raddi, notadamente na dosagem de 30% de terra de barranco e 70% de lodo de curtume desidratado.[027] With this, it is concluded that the dehydrated tannery sludge can be used as an alternative source for the production of Schinus terebínthifolíus raddi seedlings, notably in the dosage of 30% of ravine soil and 70% of dehydrated tannery sludge .
