Soil Biota In subject area: Agricultural and Biological Sciences Soil biota refers to living creatures of soil, which include microorganisms (bacteria, fungi), and soil fauna, which have diverse interaction with plants growing in that soil (Balestrini et al., 2015)....
Trade-off between ‘new’ SOC stabilisation from above-ground inputs and priming of native C as determined by soil type and residue placement Abstract Due to the geographical expanse of grasslands with depleted organic matter stocks, there has been growing interest in the management of these ecosys...
Amending soil with biochar (pyrolized biomass) is suggested as a globally applicable approach to address climate change and soil degradation by carbon sequestration, reducing soil-borne greenhouse-gas emissions and increasing soil nutrient retention. Biochar was shown to promote plant growth, especially ...
Nutrient amendment diminished bacterial functional diversity, consolidating carbon flow through fewer bacterial taxa. Here, we show strong differences in the bacterial taxa responsible for respiration from four ecosystems, indicating the potential for ta
Crop residues and soil types play an important role in soil C and N storage. The objectives of this study were to quantify the effects of crop residue quality and interactions with soil type on soil C and N, in the short- and medium-term, and to determine the responses related to the ...
作者: Stephen Porder and Oliver A. Chadwick 摘要: Plants and soils represent coevolving components of ecosystems, and while the effects of soils (e.g., nutrient availability) on plants have been extensively documented, the effect of plants on soils has received less attention. Furthermore there...
The paddy soil of Shangcheng County is belong to yellow brown soil and storage type;rapid available P and rapid available K are IV. The overall nutrient status is moderate. Aiming at the existing problem of the region's soil nutrient status,this paper put forward some countermeasures to ...
In this study, nutrient release from biochars derived from the slow pyrolysis of exhausted grape marc (EGM) at 300, 400 and 500 掳C (EGM300, EGM400 and EGM500) was investigated through five successive leaching assays in batch mode for a total duration of 10 days. Then, nutrient leaching/...
Soil enzymes are one type of the most important biological components of the soil ecosystem. They play an important role in organic matter decom- position and nutrient cycling12. For instance, the hydroxylases (e.g. urease and sucrase etc.) can hydrolyze the macromolecules, such as proteins ...
2.9 and 4.4 times respectively in 0-100 cm soil layer of greenhouse compared with the outside farmland.Senior citizens over 10 years of greenhouse soil available K moves to the bottom and loss intense.Available nutrient enrichment of soil in solar greenhouse is P N K,but the depth and ...
