Comparison of effects exerted by bio-fertilizers, NPK fertilizers, and cultivation methods on soil respiration in Chernozem soil
Soil respiration is a significant indicator of soil microbial activity; global soil respiration and decomposition processes release yearly to the atmosphere a total of 220 billion tons of carbon dioxide. Therefore, studies on the whole- or one particular aspect of soil carbon cycle aiming at optimizing agricultural carbon dioxide emissions or improving carbon sequestration contribute to a sustainable agriculture practice. In this paper we present the effects of biofertilizer application (Bacillus megaterium, Bacillus circulans, and Pseudomonas putida) on soil respiration in chernozem soil. Experiments were performed at Látókép Experimental Station, belonging to the University of Debrecen, Hungary. Additionally, we compare our results with findings of prior studies related to commercial NPK fertilizer applications (in four doses: N60P45K45; N120P90K90; N180 P135K135; and N240P180K180), and two different cultivation methods (ploughed, loosened, RTK in rows, and RTK between rows); these investigations were conducted at the same experimental station. Our results indicate lower tendency for soil respiration, when biofertilizers are applied as compared to commercialNPK fertilizers, which enables to decrease CO2 emission in the environment.We also discuss a unit change indifferent alkali absorption-based methods (Oxitop and Witkamp) to facilitate comparability of recently acquired data with results of previous long-term fertilization experiments.

La respiración del suelo es un indicador importante de la actividad microbiana; los procesos de respiración y descomposición del suelo a nivel mundial liberan anualmente a la atmósfera un total de 220 mil millones de toneladas de dióxido de carbono. Por lo tanto, los estudios sobre los aspectos del ciclo del carbono del suelo para optimizar las emisiones de dióxido de carbono agrícola o mejorar el secuestro de carbono contribuyen una práctica agrícola sostenible. En este artículo se presentan los efectos de la aplicación de biofertilizantes (Bacillus megaterium, Bacillus circulans, y Pseudomonas putida) en la respiración del suelo, en el suelo chernozem. Los experimentos se realizaron en la Estación Experimental de Látókép, perteneciente a la Universidad de Debrecen, Hungría. Además, estos resultados se compararon con los hallazgos de estudios anteriores relacionados con aplicaciones comerciales de fertilizantes NPK (en cuatro dosis: N60P45K45; N120P90K90; N180 P135K135; and N240P180K180), y dos métodos de cultivo (arado, aflojado, RTKen filas y RTK entre filas); estas investigaciones se llevaron a cabo en la misma estación experimental. Los resultados indican una menor tendencia a la respiración del suelo cuando se aplican biofertilizantes en comparación con los fertilizantes NPK comerciales, lo que permite disminuir la emisión de CO2 en el medio ambiente. También se discutió un cambio unitario en los diferentes métodos basados en la absorción de álcalis (Oxitop y Witkamp) para facilitar la comparación de los datos adquiridos recientemente con los resultados anteriores de experimentos de fertilización a largo plazo. A respiração do solo é um indicador importante da actividade microbiana; os processos globais de respiração e decomposição do solo libertam anualmente um total de 220 mil milhões de toneladas de dióxido de carbono para a atmosfera. Portanto, os estudos sobre aspectos do ciclo do carbono do solo para optimizar as emissões agrícolas de dióxido de carbono ou melhorar o sequestro de carbono contribuem para uma prática agrícola sustentável. Este artigo apresenta os efeitos da aplicação de biofertilizantes (Bacillus megaterium, Bacillus circulans, e Pseudomonas putida) na respiração do solo em solo chernozem. As experiências foram realizadas na Estação Experimental de Lactokép, pertencente à Universidade de Debrecen, Hungria. Além disso, estes resultados foram comparados com os resultados de estudos anteriores relacionados com aplicações comerciais de fertilizantes NPK (em quatro doses: N60P45K45; N120P90K90; N180 P135K135; and N240P180K180), e dois métodos de cultivo (aragem, afrouxamento, RTK em filas e RTK entre filas); estas investigações foram realizadas na mesma estação experimental. Os resultados indicam uma menor tendência para a respiração do solo quando os biofertilizantes são aplicados em comparação com os fertilizantes comerciais NPK, o que permite uma diminuição das emissões de CO2 para o ambiente. Foi também discutida uma mudança unitária nos diferentes métodos baseados na absorção de álcalis (Oxitop e Witkamp) para facilitar a comparação dos dados recentemente adquiridos com os resultados anteriores de experiências de fertilização a longo prazo.
