Lime and phosphogypsum application management: changes in soil acidity, sulfur availability and crop yield

open access: yesRevista Brasileira de Ciência do Solo, 2021
Oxisols ( Latossolos ) are widely distributed in tropical zones and generally characterized by high levels of surface and subsurface acidity. In Brazil, most Oxisols are managed under no-till conditions with surface application of acidity amendments ...

Abstract saturation-based inference

open access: yes18th Annual IEEE Symposium of Logic in Computer Science, 2003. Proceedings., 2003
Solving goals---like deciding word problems or resolving constraints---is much easier in some theory presentations than in others. What have been called ``completion processes'', in particular in the study of equational logic, involve finding appropriate presentations of a given theory to solve easily a given class of problems.

Correction of soil acidity in the subsurface of an oxisol with sandy loam texture under no-tillage Correção da acidez do solo em subsuperfície de um latossolo de textura franco-arenosa sob plantio direto

open access: yesRevista Brasileira de Ciência do Solo, 2009
In Rio Grande do Sul State (RS), Southern Brazil, aluminum saturation in many areas under no-till system is high and base saturation low in the 0.10-0.20 m layer (subsurface), which may reduce the grain yield of annual crops.

Ecohydrological analysis of a groundwater influenced blanket bog: occurrence of Schoenus nigricans in Roundstone Bog, Connemara, Ireland [PDF]

open access: yesMires and Peat, 2016
Since the late 1960s, the occurrence of Schoenus nigricans in Irish blanket bogs has been attributed to inputs of salt spray to the blanket bogs, due to their proximity to the coast and the predominant westerly winds from the Atlantic Ocean. To test this
