Cattle Manure Bioconversion Effect on the Availability of Nitrogen, Phosphorus, and Potassium in Soil

Daniel Pazzini Eckhardt, Marciel Redin, Natielo Almeida Santana, Lessandro De Conti, Jorge Dominguez, Rodrigo Josemar Seminoti Jacques, [...]


ABSTRACT The efficiency index (EI) refers to the ratio of nutrients mineralized/made available in the soil to the total amount of nutrients added by organic fertilizer. Therefore, understanding the EI is essential for recommendation of organic fertilization. The aim of this study was to evaluate the availability through mineralization and the efficiency index of nitrogen (N), phosphorus (P), and potassium (K) in organic fertilizers produced from cattle manure. The following treatments were evaluated in an incubation experiment under controlled conditions: […]

Soil Biological, Chemical, and Physical Properties After a Wildfire Event in a Eucalyptus Forest in the Pampa Biome

Natielo Almeida Santana, Cedinara Arruda Santana Morales, Diego Armando Amaro da Silva, Zaida Inês Antoniolli, Rodrigo Josemar Seminoti Jacques


ABSTRACT Wildfire events cause considerable environmental disturbance but few studies have examined changes in soil properties due to fire. This study aimed to assess the effect of a wildfire event on chemical, physical, and biological properties of the soil in a eucalyptus forest in the Pampa biome. Part of a seven-year-old eucalyptus forest was affected by a wildfire event that lasted for two days. Soil and plant litter sampling was performed in three areas: in the forest that was not […]

Microbiological Indicators of Pasture Soil with Successive Applications of Pig Slurry

Danni Maisa da Silva, Zaida Inês Antoniolli, Rodrigo Josemar Seminoti Jacques, Andressa de Oliveira Silveira, Diego Armando Amaro da Silva, Magnus Maurício Rache, [...]


ABSTRACT Pig slurry use as soil fertilizer is a common practice in southern Brazil. In spite of the benefits of reusing waste, this practice poses serious environmental risks. Microbiological indicators of soil quality are very sensitive and allow soil environment conditions to be monitored. The aim of this study was to evaluate the microbiological quality of pasture soils with different histories of successive use of pig slurry. Determinations were made of C content in the microbial biomass, soil microbial respiration, […]
