Highlights
Silicate weathering contra carbonate weathering: Silicate weathering is known to sequestrate carbon, e.g.: CaSiO3 + 2CO2 + H2O > Ca++ + 2HCO-- +SiO2 [1]
Are represented results of combined regressions, e.g. the first one shows that combined regression of [Hum.min] was explained 79.6 % by [pH.min.68;Temp.(6190)], p< 0.001, coefficient signs (-/+)
Carbon capture via silicate weathering has been treated comprehensively e.g. in [3], including reduction of carbon loss caused by liming agents
Summary
Silicate weathering contra carbonate weathering: Silicate weathering is known to sequestrate carbon, e.g.: CaSiO3 + 2CO2 + H2O > Ca++ + 2HCO-- +SiO2 (soluble) [1]. Importance of this process has been discovered lately: earlier “silicic” bedrock was interpreted to “promote the acidity of soils” [2]. Carbon capture via silicate weathering has been treated comprehensively e.g. in [3], including reduction of carbon loss caused by liming agents. Carbon loss has generally been associated positively with annual management practices and negatively with clay soils [5]. Inter-periodical changes are assessed by pH from periods 1966-1970 (“68”) and
