Title A name given to the resource Efeito da homeopatia Ammonium Carbonicum na minimização da lixiviação de nitrato Effect of the homeopathy Ammonium Carbonicum in the minimization of nitrate leaching Creator An entity primarily responsible for making the resource Carolina Cardoso Lisboa, Sérgio Ely Valadão Gigante de Andrade Costa, Daniel Melo de Castro, João José Marques Description An account of the resource Avaliou-se o efeito da solução homeopática Ammonium Carbonicum em duas dinamizações, CH3 e CH30, sobre a lixiviação de NO-3. A hipótese inicial foi a de que essas soluções homeopáticas atuariam na microbiota do solo otimizando a utilização de N pela planta. Esse estudo foi conduzido em casa-de-vegetação e utilizaram-se amostras deformadas do horizonte A de um Latossolo Vermelho distroférrico típico muito argiloso, 00,15 m, localizado no campus da UFLA. As colunas de solo foram semeadas com milho (Zea mays L.) e tinham 0,20 x 0,20 m. A irrigação e medição do volume lixiviado foi realizada diariamente. A aplicação dos tratamentos homeopáticos foi realizada via irrigação. As análises do lixiviado foram feitas duas vezes por semana. No lixiviado, mediram-se os teores de NO-3 e NH+4 Após 93 dias, as colunas foram seccionadas em camadas de 0,05 m e as amostras, analisadas quanto à fertilidade, incluindo NO-3, NH+4 e N total. O delineamento experimental foi inteiramente casualizado, com três repetições, num esquema duplo-cego com placebo. O efeito da solução homeopática na minimização da lixiviação deNO-3 não foi relevante nas condições deste estudo.The objective of this study was to evaluate the effect of the homeopathic solution Ammonium Carbonicum in two dynamizations CH3 and CH30 on NO-3 leaching. The early hypothesis was that those homeopathic solutions would act upon soil microbiota optimizing the use of N by the plant. This study was conducted in greenhouse and samples of the A horizon of a very clayey typic dystroferric Red Latosol, 00.15m, situated on the UFLA campus were utilized. The soil columns were sowed with corn (Zea mays L.) and were 0.20 x 0.20 m. Irrigation and leached volume measurement was performed daily. The application of the homeopathic treatments was accomplished via irrigation. The analyses of the leachate were done twice a week. In the leachate, the contents of NO-3 and NH+4 were measured. After 93 days, the columns were sectioned in 0.05-m layers and the samples were analyzed in relation to fertility, including NO-3 , NH+4 and total N. The experimental design was completely randomized with three replicates, in a double-blind scheme with a placebo. The effect of the homeopathic solution in minimizing NO-3 leaching was not significant in the conditions of this study.
