Efeito da homeopatia Ammonium Carbonicum na minimização da lixiviação de nitrato

Abstract

RESUMOAvaliou-se o efeito da solução homeopática Ammonium Carbonicum em duas dinamizações, CH3 e CH30, sobre a lixiviação de 3 NO . 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, 0 0,15 m, localizado no campus da UFLA. Termos para indexação: Ammonium Carbonicum, agricultura orgânica, nitrato. ABSTRACTThe objective of this study was to evaluate the effect of the homeopathic solution Ammonium Carbonicum in two dynamizations CH3 and CH30 on 3 NO 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, 0 0.15m, 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 NH 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 3 NO leaching was not significant in the conditions of this study.

Agronomic performance and protein content of Pereskia aculeata Mill. using organic chicken

“…Organic food production has increased over recent years, mainly due to population demand for more sustainable alternatives and higher quality products; making it necessary to search new techniques to improve farming systems, focusing on the quality and efficiency of nutritional management. Nitrogen is crucial for plant growth and is available to them in the soil and organic animal fertilizers (Lisboa et al, 2007). In addition to providing nutrients that are released via mineralization process, organic fertilizers are the source of energy for microorganisms that improves soil structure and moisture-holding capacity.…”

“…The interest in organic products stimulated the search for studies in the development of new techniques for this production system, in the search for better efficiency mainly in nutrient management. It is also important to highlight the the availability of nitrogen from sources of plant or animal organic fertilizers or even what is available in soil organic matter (Lisboa et al, 2007). One of the most widely available and accessible organic materials among producers in several regions of Brazil is manure, which can be cattle, horses, pigs and chicken.…”

<b>Dynamized high dilutions for management of the leafcutter ant <i>Acromyrmex laticeps</i> Emery (Hymenoptera: Formicidae)

“…A study conducted by Mapeli (2015) showed that homeopathic solutions deterred feeding by antibiosis via interfering with the biological cycle of Ascia monuste orseis on cabbage (Brassica oleracea). According to Lisboa, Costa, Castro, and Marques (2007), due to their nonresidual nature, high dilution preparations assure the lack of side effects, and studies focus mainly on the efficiency of such technologies as a contribution to redesigning ecologically sustainable agricultural systems. The preparation methods for high dynamized dilutions are established in the Homeopathic Pharmacopoeia, allowing a variety of dilution scales (Cesar, 2003).…”
