CHEMICAL AND MICROBIOLOGICAL ATTRIBUTES UNDER DIFFERENT SOIL COVER [PDF]

CERNE, 2017
ABSTRACT A challenge for the environmental recovery of degraded areas is the search for soil data. In this process, the microbiological parameters and soil chemicals are potential indicators of soil quality. This study aimed to evaluate soil quality based on microbiological and chemical soil attributes in different areas involving environmental ...

Chemical attributes of soils with eggshell application

Científica, 2017
Eggshell is an industrial residue which can be used as an acidity corrective, but its employment must follow some criteria. The objective of the present work was to evaluate the effect of eggshell on fertility attributes of soils with different clay contents. The experiment was conducted under laboratory conditions, from September to December 2015.

SAMPLING OF CHEMICAL ATTRIBUTES IN FOREST SOILS

FLORESTA, 2019
Information about sample adequacy that represents soil chemical attributes distribution are fundamental for a better rationalization of the use of correctives and fertilizers. The objective was to evaluate the variability of these attributes and to size the minimum number of composite samples to represent the fertility of forest soils.

Dose-dependent changes of chemical attributes in irradiated sausages

Meat Science, 2011
To determine the effects of irradiation on the chemical attributes of sausages, TBARS values, volatile compounds, gaseous compounds, and hydrocarbons of vacuum-packaged sausages were analyzed during 60 d of refrigerated storage. A sulfur-containing volatile (dimethyl disulfide), a gas (methane), and radiation-induced hydrocarbons (1-tetradecene ...
