The rhizosphere of tropical grasses as driver of soil ...

1. Introduction. Defined as the volume of soil directly affected by roots, the rhizosphere provides a chemical environment that boosts biological activity (Rovira and Davey, 1973).This biogeochemical environment differs from that of the bulk soil due to the release of metabolic products by roots and microorganisms, which can lead to more intense mineral alteration …

Caustic Solution

An optional sand filter coalescer downstream of the extractor can improve the quality of the treated product. Also, if H 2 S or CO 2 is present in substantial amounts, the extractor column can be preceded by a caustic (or amine) prewash for acid gas removal, which can minimize caustic consumption. There are other enhancements that can be ...
