Investigation and Assessment of Dependences of the Total Carbon on Ph in Neris Regional Park Soil

Abstract

Soil is one of the most important natural subsystems of the Earth's landscapes, which is exceptionally vital for a human being as the main source of food resources. In order to take care of the future one of the most relevant problems of the mankind is to preserve soils of the Earth, their fertility and normal state under conditions of the increasing technogenic effect and degradation of natural landscapes. As the global warming has already started, its after‐effects, which will be invertable faced by the Lithuanian agriculture, must be overcome as an additional negative factor. The paper aims at revealing the dependence of the total carbon on pH. It also focuses on the impact of climate change on the total carbon and soil degradation. Santrauka Dirvožemis yra vienas iš svarbiausiu gamtiniu Žemes landšaftu posistemiu, išimtinai svarbus žmogui kaip pagrindinis maisto ištekliu šaltinis. Rūpinantis ateitimi, viena iš aktualiausiu žmonijos problemu – išsaugoti Žemes dirvožemius, ju derlinguma ir normalia būkle vis didejančio technogeninio poveikio ir gamtiniu landšaftu degradacijos salygomis. Kaip papildoma neigiama faktoriu privalu iveikti prasidejusio globalaus atšilimo pasekmes, su kuriomis neišvengiamai susidurs ir Lietuvos žemes ūkis. Straipsnyje siekiama atskleisti bendrosios anglies priklausomybe nuo pH, atkreipti demesi i klimato kaitos itaka dirvožemio degradacijai. Резюме Почва является одной из важнейших подсистем природных ландшафтов Земли, имеющей особенно важное значение для людей в качестве основного источника пищи. Одной из наиболее неотложных задач, стоящих перед человечеством, обеспокоенным своим будущим, является сохранение почв Земли, их плодородия и здорового состояния в условиях усиливающегося техногенного воздействия и деградации природного ландшафта. При этом придется преодолеть и уже начавшееся глобальное потепление, которое неизбежно коснется литовского сельского хозяйства. В статье предпринята попытка выявить зависимость общего углерода от рН, а также обратить внимание на последствия, наносимые изменением климата общему углероду, а также на деградацию почв.

“…Respiration rates vary significantly among major biome types, and side-by-side comparisons of different plant communities frequently demonstrate differences in soil respiration rates. Such findings indicate that vegetation type is an important determinant of soil respiration rate, and therefore changes in vegetation have the potential to modify the response of soils to environmental change (Baltrėnas et al 2010). No predictable differences in soil respiration were found between cropped and vegetation-free soils, forested and cropped soils, or grassland and cropped soils, possibly due to the diversity of crops and cropping systems included (Raich and Tufekcioglu 2000).…”

“…CO 2 flux from soil is a good indicator of the overall biological activity of the soil and is often used when studying the soil carbon cycle. Scientific and statistical studies state that controlling soil respiration and carbon (C) cycling are of particular interest because soils contain twice as much C as the atmosphere and three times as much as vegetation (Granier et al 2000;Han et al 2007;Horák and Šiška 2006;Baltrėnas et al 2010).…”

Soil Quality Attributes Related to Urbanization in Brazilian Watershed

“…Hence, other studies like this one should be carried out and reliable data should be systematically surveyed. One of the reasons is that the effect is highly variable according to geographic region (Edmondson et al 2011;Hagan et al 2012), the environmental characteristics of the region (Baltrenas et al 2010;Templer et al 2012), as well as the modality and intensity of urbanization (Alberti 2005;Boeckx et al 2006).…”

Evaluation of Total Organic Carbon Quantity and Emissions of CO2 from Soil Into the Atmosphere Near Street

“…Consequently, it is very important to evaluate what is soil pollution impact on soil quality indicators -TOC and CO 2 emissions from soil. Scientific and statistical studies state that controlling soil respiration and carbon (C) cycling are of particular interest because soils contain twice as much C as the atmosphere and three times as much as vegetation [7]. Unlike the atmosphere, soil air composition is very dynamic.…”
