Soil Quality Indicators
Total organic carbon (TOC) is the carbon (C) stored in soil organic matter (SOM). Organic carbon (OC) enters the soil through the decomposition of plant and animal residues, root exudates, living and dead microorganisms, and soil biota. SOM is the organic fraction of soil exclusive of nondecomposed plant and animal residues. Nevertheless, most analytical methods do not distinguish between decom...
متن کاملSoil carbon dioxide efflux from a claypan soil affected by surface compaction and applications of poultry litter
The effects of soil compaction on soil physical properties may alter soil microbial activities and processes, including carbon (C) cycling, and possibly affect agricultural production and environmental degradation. This study investigated the effects of surface soil compaction on soil C mineralization in a claypan soil amended with poultry litter (i.e. turkey excrement mixed with pine shavings ...
متن کاملThe impact of alum addition on organic P transformations in poultry litter and litter-amended soil.
Poultry litter treatment with alum (Al(2)(SO(4))(3) . 18H(2)O) lowers litter phosphorus (P) solubility and therefore can lower litter P release to runoff after land application. Lower P solubility in litter is generally attributed to aluminum-phosphate complex formation. However, recent studies suggest that alum additions to poultry litter may influence organic P mineralization. Therefore, alum...
متن کاملEffect of poultry litter and livestock manure on soil physical and biological indicators in a rice-wheat rotation system
Organic manure is considered as a beneficial fertilizer on soil quality and an excellent alternative resource of chemical fertilizer (CF). However, organic manure from intensive farms may have a negative impact on soil quality because of containing some harmful components, such as heavy metal and antibiotics. The aim of this study was to determine the influence of poultry litter (PL) and livest...
متن کاملIndicators for evaluating soil quality
Interactions between the diversity of primary producers (plants) and of decomposers (microbes and mesofaunal communities), the two key functional groups that form the basis of all ecosystems have major consequences on the functioning of agricultural ecosystems. Soil microorganisms control the transformation and mineralization of natural compounds and xenobiotics. The soil microbiota, existing i...
