Much of the fertilizers currently found on the market are known to cause environmental damage as they are easily leached and carried to waterways promoting effects such as eutrophication. Therefore, it is necessary to formulate fertilizers that meet agricultural demand and as sustainable as possible. Thus, this work investigated a fertilizer based on a glass matrix, called Agriglass, which is composed of phosphorus, boron, potassium, zinc and copper, and has solubility and controlled release, thus avoiding undesirable nutrient losses to the environment. Vitreous samples were prepared by differentiating zinc concentrations 0, 5, 10, 15 and 25% in a first step. The composition with 15% Zn and 1% Cu was prepared in a second step. The samples were characterized by their electrical conductivity hygroscopy, Raman spectroscopy, scanning electron microscopy and X-ray fluorescence spectroscopy. Agriglass fertilizer was tested at 4 different concentrations 0, 1, 10, 100 mg/g of soil in maize hybrids grown in vitro and in soil. The antimicrobial power of the nutritive compound was also analyzed. It has been proven by the methodologies that the fertilizer presents controlled release, has an ideal pH for most crops, and has a high hygroscopicity when there are low concentrations of Zn. Regarding the methodologies that involved its effect on plant growth, it was found that in vitro cultivation was not efficient in order to identify agronomic differences when compared to different formulations, due to partial solubilization of the vitreous compound in the culture medium. As for the soil test, at the evaluated development stage, it was not possible to observe differences between the plants with different formulation levels, since they still absorbed nutrients present in the substrate and in the seed itself. Moreover, the antimicrobial evaluation showed that agriglass is efficient in controlling the fungus Thielaviopsis paradoxa, which causes plant pathogens, with the most inhibiting formulation containing 0% Zn and 0% Cu. In this sense, the tested formulation has high potential to be applied in agriculture. A busca por compostos que agridam minimamente o meio ambiente está cada vez maior. Sabe-se que muitos dos fertilizantes encontrados atualmente no mercado acarretam danos ambientais, uma vez que são facilmente lixiviados e levados até os cursos d’água promovendo efeitos indesejáveis como a eutrofização. Logo, é necessário a formulação de fertilizantes que atendam a demanda agrícola e que sejam o mais sustentáveis possível. Dessa forma, este trabalho investigou um fertilizante a base de uma matriz vítrea, denominado Agriglass, o qual é composto por fósforo, boro, potássio, zinco e cobre, e possui solubilidade e liberação controlada, evitando assim, perdas indesejáveis de nutrientes para o ambiente. Preparou-se as amostras vítreas diferenciando as concentrações de zinco 0, 5, 10, 15 e 25 % mol numa primeira etapa. A composição com 15 % mol de Zn e 1 % mol de Cu foi preparada numa segunda etapa. As amostras foram caracterizadas em condutividade elétrica higroscopia, espectroscopia de Raman, microscopia eletrônica de varredura e espectroscopia de fluorescência de raio X. O fertilizante Agriglass foi testado com 4 concentrações diferentes 0, 1, 10, 100 mg Agriglass/g de solo em híbridos de milho cultivados in vitro e no solo. Analisou-se ainda o poder antimicrobiano do composto nutritivo. Comprovou-se por meio das metodologias, que o fertilizante pode ser considerado de liberação controlada, possui um pH ideal para a maioria das culturas, e possui uma higroscopicidade elevada em baixas concentrações de Zn. Em relação às metodologias que envolveram seu efeito no crescimento vegetal, verificou-se que no cultivo in vitro não foi eficiente a fim de identificar diferenças agronômicas quando comparadas às diferentes formulações, devido à não total solubilização do composto vítreo no meio de cultivo. Já o teste no solo, no estágio de desenvolvimento avaliado, não foi possível observar diferença entre as plantas com diferentes níveis de formulação, uma vez que essas ainda absorveram nutrientes presentes no substrato e na própria semente. Ademais, a avaliação antimicrobiana, mostrou que o Agriglass é eficiente no controle do fungo Thielaviopsis paradoxa, causador de patogenias em plantas, sendo que a formulação mais inibidora foi a que continha 0 % Zn e 0 % Cu, por apresentar maior liberação de Potássio, componente antifúngico. Nesse sentido, a formulação testada apresenta elevado potencial para ser aplicado na agricultura. 2021-01-19T19:28:37Z 2021-12-09 2021-01-19T19:28:37Z 2019-11-04 bachelorThesis RUSCHEL, Latoya Creslem Batista.
