Mechanisms of carbon and nutrient release from acid impacted soils: Investigating competitive sorption and aggregate dispersion [PDF]
, 2018 Dissolved organic carbon (DOC) and associated nutrients are of critical importance to natural biogeochemical cycling. In recent decades, increased amounts of DOC have been observed in Northern Hemisphere surface waters recovering from acid deposition ...

CALAGEM E SILICATAGEM EM SOLO INCUBADO COM DIFERENTES UMIDADES
Colloquium Agrariae, 2012 The lime is the acidity corrective more used in brazilian agricultural soils, but important benefits can be obtained from calcium and magnesium silicates. The aim of this study was to compare the effect of neutralizing soil acidity by application of lime

Effects of deep vertical placement of lime on corn and soybean response and soil chemical properties in conservation tillage systems [PDF]
from introductionSoil acidity is one of the most influential factors in limiting crop production around the world. Roughly 30% of the Earth's total land area and as much as 70% of potentially farmable land is affected by soil acidity (Rengel, 2003). Soil

Nature, 1950 ALTHOUGH the protein nature of at least one-third of the organic nitrogen of soil has been established1,2, very little is known of the amino-acid composition of this protein material. The isolation of amino-acids from soil hydrolysates is rendered difficult by the presence of large amounts of extraneous inorganic and organic material.

Modification of the simple mass balance equation for calculation of critical loads of acidity. [PDF]
, 1995 Over the last few years, the simple mass balance equation for the calculation of critical loads of acidity has been gradually modified as the underlying critical load concepts have developed and as problems with particular forms of the equation have been
