Resumo
O presente trabalho aborda a utilização dos materiais poliméricos para melhoria do solo e sua influência na fertilidade do solo. Contou-se com a colaboração com a Professora Roselena, do Laboratório de Materiais Poliméricos e Biossorventes, Universidade Federal de São Carlos (UFSCar), que forneceu os fertilizantes poliméricos.Amostras coletadas na região de Diadema, foram analisadas após incubação com fertilizantes poliméricos, com objetivo de analisar o fósforo presente nas amostras, por meio de técnicas como o sensor de fertilidade, espectrofotometria de UV-vis, espectrotometria de fluorescência de raio x (FRX) e teste de pH, para estudo comparativo das amostras e fertilizantes. Concluiu-se que os fertilizantes influenciam na fertilidade do meio, onde obteve-se concentração de fósforo (P) maior para a amostra com fertilizante Comercial, com 6,289 mol/L e pH 6,86, mostrando maior disponibilidade desse elemento, reduzindo sua adsorção no solo. E os resultados do FRX mostraram que o Teor de P estava presente nas amostras com fertilizante CMC/Ze-F e CMC/Ze-Mult e procedeu à quantificação de demais elementos nas amostras impregnadas. A presença de fertilizantes nas amostras de solo, mostraram a influência significativa destes no meio , mostrando sua influência quanto ao fósforo presente e o aumento de pH, ajudando na fertilidade do meio. O trabalho trouxe novas perspectivas que podem ser elaboradas em novos estudos e pesquisas, a fim de entender sobre as influências dos fertilizantes nos solos.
The present work addresses the use of polymeric materials for soil improvement and its influence on soil fertility. We counted on the collaboration with Professor Roselena, from the Laboratory of Polymeric Materials and Biosorbents, Federal University of São Carlos (UFSCar), who provided the polymeric fertilizers.Samples collected in the region of Diadema, were analyzed after incubation with polymeric fertilizers, in order to analyze the phosphorus present in the samples, through techniques such as fertility sensor, UV-vis spectrophotometry, x-ray fluorescence spectrometry (XRF) and pH test, for comparative study of samples and fertilizers. It was concluded that fertilizers influence the fertility of the medium, where a higher concentration of phosphorus (P) was obtained for the sample with Commercial fertilizer, with 6.289 mol/L and pH 6.86, showing greater availability of this element, reducing its adsorption in the soil. The results of the XRF showed that the P content was present in the samples with fertilizer CMC/ Ze-F and CMC/ Ze-Mult and proceeded to the quantification of other elements in the impregnated samples. The presence of fertilizers in the soil samples showed the significant influence of these in the medium, showing its influence on the phosphorus present and the increase of pH, helping in the fertility of the medium. The work brought new perspectives that can be elaborated in new studies and research in order to understand the influences of fertilizers on soils.
