Resumo: | This study aimed to evaluate short-term influence of application of organo-mineral or mineral fertilizers and using irrigation with saline water on microbial community and enzymatic activity of soil, besides monitor some of its chemicals attributes. The experiment was conducted in a protected environment, with controlled air temperature and soil moisture. It was arranged in a 4 x 2 factorial design, with four salinities of irrigation water (0.1, 1.8, 3.6, and 7.2 dS m -1) and two types of fertilizer (organo-mineral and mineral). The experimental units consisted of PVC columns filled with soil, which were incubated and destroyed for analysis 20 days after the beginning of the experiment. The soil was kept with moisture close to 90% of field capacity, by measuring the weight of the columns in a daily basis and refilling the lost moisture with saline and non-saline waters, according to the treatments.The irrigation with saline water increased electrical conductivity, exchangeable sodium content, and pH of soil, especially in the adjacencies of granules with application of the organo-mineral fertilizer in relation to mineral. Carbon of microbial community and enzymatic activity of soil were negatively impacted by salt/sodic stress. The presence of organic material in the organo-mineral fertilizer did not increase ability of soil microbiota to tolerate salinity and sodicity. |

Objetivou-se avaliar a influência em curto prazo da aplicação de fertilizante organomineral ou mineral e irrigação com água salina sobre a comunidade microbiana e a atividade enzimática do solo, além de monitorar alguns de seus atributos químicos. O experimento foi realizado em ambiente protegido com controle da temperatura do ar e da umidade do solo. O delineamento foi organizado em esquema fatorial 4 x 2, quatro salinidades crescentes da água de irrigação (0,1, 1,8, 3,6 e 7,2 dS m -1 ) e dois tipos de fertilizante (organomineral e mineral). As unidades experimentais constaram de colunas de PVC preenchidas com solo, as quais foram incubadas e destruídas para análise aos 20 dias após a montagem. O solo foi mantido com umidade próxima a 90% da capacidade de campo, por meio de pesagens diárias das colunas e reposição da umidade perdida com as águas não salinas e salinas, em função dos tratamentos. A irrigação com águas de salinidade crescente aumentou a condutividade elétrica, o conteúdo de sódio trocável e o pH do solo, principalmente nas adjacências dos grânulos com aplicação de fertilizante organomineral em relação ao mineral. O carbono da comunidade microbiana e a atividade enzimática do solo foram influenciados negativamente pelo estresse salino/sódico. A presença de material orgânico no fertilizante organomineral não aumentou a capacidade da microbiota do solo em tolerar a salinidade e a sodicidade.
