Abstract:

Many New Zealand soils are known to produce pastures deficient in cobalt (Co) for grazing ruminants; however, the development of an effective soil diagnostic test for Co is hindered by the lack of knowledge of the forms and distribution of Co in New Zealand soils. A sequential fractionation technique was used to determine the forms and concentrations of native and/or fertiliser derived soil Co in 18 New Zealand grassland topsoils, and the distribution and interrelationships of Co between fractions compared with those for manganese (Mn). Previous studies in other countries have indicated a stro

Abstract:

The concurrent presence of arsenic (As) and cadmium (Cd) contamination in soil is widespread and severe, highlighting the need for remediation. However, remediating As and Cd co-contaminated soils is more complex than remediating soils contaminated with a single heavy metal due to the opposite properties of As and Cd in soil. Thus, the different forms of As and Cd in co-contaminated soils and their transformation rules have been systematically reviewed in this paper. Simultaneously, hyperaccumulators and immobilization amendments used in the remediation of As–Cd co-contaminated soil were revie

Abstract. Soil carbon monoxide (CO) fluxes represent a net balance between biological soil CO uptake and abiotic soil and (senescent) plant CO production. Studies largely from temperate and boreal forests indicate that soils serve as a net sink for CO, but uncertainty remains about the role of tropical rainforest soils to date. Here we report the first direct measurements of soil CO fluxes in a tropical rainforest and compare them with estimates of net ecosystem CO fluxes derived from accumulation of CO at night under stable atmospheric conditions. Furthermore, we used laboratory experiments t

The results indicated that (1) changes in soil solution pH and IC lower the adsorption of SDZ in paddy soils. (2) Increase of DOC facilita

Increased soil temperatures will potentially increase the release of carbon dioxide (CO2) from temperate forest soils, resulting in important positive feedback on climate change. Dark CO2 fixation by microbes can recycle some of the released soil CO2, and CO2 fixation rates are reported to increase under higher temperatures.

Abstract:

Carbonation of lime modified soil could capture carbon dioxide (CO_2) alongside strength improvement for road pavement materials. Due to large amounts of 〖CO〗_2 emissions and increasing cost of primary soil stabilizers such as lime and cement, the use of lime-based wastes have been encouraged. This paper reviews waste materials based on separate potential for 〖CO〗_2 capture and strength improvement of soils. Such wastes include cement kiln dust (CKD), saw dust ash (SDA), steel slag, basic oxygen steel (BOS) slag, ground granulated blast furnace slag (GGBS), coal fly ash (CFA) and cattle bone p

Soil microorganisms play a main role in the nutrient cycle and they also play an important role in soil health. This article studies the influence of three rates of biochar (0.5, 1 and 3%) in comparison with control (0 biochar) in two different soils (Valečov and Čistá) on soil microbiota activities. The biochar was prepared from 80% of digestate from Zea mays L. and 20% of cellulose fibres by pyrolysis (470°C, 17 min). The biochar ability to influence microbial processes in soil was determined by respiration and nitrification tests. There were no significant differences between basal respirat
