Relationships between base saturation, effective base saturation and soil pH as the references for the development and verification of criteria for international soil classification

open access: yesGeoderma
Base saturation (BS) and effective base saturation (BSe) are widely used soil characteristics, commonly involved in the criteria of soil classification, including the World Reference Base for Soil Resources (WRB) system.

Reductions and Saturation Reductions of (Abstract) Knowledge Bases

open access: yesElectronic Notes in Theoretical Computer Science, 2014
Rough set theory is a useful tool for dealing with fuzzyness and uncertainty of knowledge. In rough set theory, knowledge reductions and generatings are important research topics and critical steps of knowledge acquisition.

Saturations of subalgebras, SAGBI bases, and U-invariants [PDF]

open access: yesJournal of Symbolic Computation, 2022
Given a polynomial ring $P$ over a field $K$, an element $g \in P$, and a $K$-subalgebra $S$ of $P$, we deal with the problem of saturating $S$ with respect to $g$, i.e. computing $Sat_g(S) = S[g, g^{-1}]\cap P$. In the general case we describe a procedure/algorithm to compute a set of generators for $Sat_g(S)$ which terminates if and only if it is ...

Forms of lime application and use of phosphogypsum in low acid soil in southern Brazil: soybean-wheat yield and soil chemical properties

open access: yesRevista Brasileira de Ciência do Solo, 2021
Brazil is currently the leading country in no-till (NT) farming, particularly on Ferralsols (Latossolos), the most abundant soil type. These soils are characterized by subsurface acidity that cannot be effectively corrected by surface application of ...
