The core microbiota of a neutral mine drainage and the surrounding high heavy metal content soil at a Brazilian copper mine were characterized by 16S rDNA pyrosequencing. The core microbiota of the drainage was dominated by the generalist genus Meiothermus. The soil samples contained a more heterogeneous bacterial community, with the presence of both generalist and specialist bacteria. Both env...

UNLABELLED Accumulating empirical evidence over the last 60 years has shown that the reduction of N2O to N2 is impaired by low soil pH, suggesting that liming of acid soils may reduce N2O emissions. This option has not gained much momentum in global change research, however, possibly due to limited understanding of why low pH interferes with N2O reductase. We hypothesized that the reason is tha...

Soil sampling, collection, and analysis are a costly labor-intensive activity that cannot cover the entire farmlands; hence, it was conceived to use high-speed open-source platforms like Google Earth Engine in this research estimate soil characteristics remotely using high-resolution satellite data. The objective of pH from Sentinel-1, Sentinel-2, Landsat-8 satellite-derived indices; data missi...

In this study, we evaluated the effects of municipal solid waste compost supplemented with inorganic N on physicochemical properties soil, plant growth, nitrate concentration, and antioxidant activity in spinach. Experiments were carried out neutral acidic soils that low organic matter. A fertilized soil was used as a control, while four treatments—two rates 35 70 t ha−1, or not (92 kg ha−1 Ca ...

To increase the fertility of neutral salt pans and improve their physico-chemical properties under intensive irrigation, it is necessary to apply a set measures. Reclamation saline soils should be aimed at reducing content exchangeable sodium in absorbing complex, improving chemical water-physical creating highly fertile root-inhabited soil layer. When developing flats irrigation conditions, bo...

Phosphorus (P) availability is commonly assumed to limit productivity in many tropical soils, yet there relatively little information on the phosphorus chemical forms, distribution, and transformations that P acid soil. The best way obtain of separate fractions soil using series solvents different strength sequential analysis. method used was Chang Jackson Formation forms their binding largely ...

Aluminium (Al) toxicity is the main abiotic stress limiting plant productivity in acidic soils that are widely distributed among arable lands. Plant species differ in the level of Al resistance showing intraspecific and interspecific variation in many crop species. However, the origin of Al-tolerance is not well known. Three annual species, difficult to distinguish phenotypically and that were ...

For centuries, biologists have studied patterns of plant and animal diversity at continental scales. Until recently, similar studies were impossible for microorganisms, arguably the most diverse and abundant group of organisms on Earth. Here, we present a continental-scale description of soil bacterial communities and the environmental factors influencing their biodiversity. We collected 98 soi...
