Revisiting the hypothesis that fungal-to-bacterial dominance characterizes turnover of soil organic matter and nutrients
Resolving fungal and bacterial groups within the microbial decomposer community is thought to capture disparate life strategies for soil microbial decomposers, associating bacteria with an r-selected strategy for carbon (C) and nutrient use, and fungi with a K-selected strategy. Additionally, food-web model-based work has established a widely held belief that the bacterial decomposer pathway in...
متن کاملOrganic matter turnover in soil physical fractions following woody plant invasion of grassland: Evidence from natural
Soil physical structure causes differential accessibility of soil organic carbon (SOC) to decomposer organisms and is an important determinant of SOC storage and turnover. Techniques for physical fractionation of soil organic matter in conjunction with isotopic analyses (dC, dN) of those soil fractions have been used previously to (a) determine where organic C is stored relative to aggregate st...
متن کاملOrganic Carbon and Organic Matter Levels in Sediments of the Strait of Hormoz, the Persian Gulf
Total organic carbon has a major influence on both the chemical and biological processesthat take place in sediments. Algal bloom is one of the organic carbon levels in aquatic ecosystems. In 2009 algal bloom occurred in the Hormozgan province and prolonged for months, which finally setteled down in 2010. In this study the variations of total organic carbon (TOC), organic matter (TOM) and tot...
متن کاملInvestigating the Effect of Soil Organic Matter on Gypsum Block Calibration for Measuring Soil Volumetric Moisture Content
Continuous soil moisture assessment and evaluation is essential for irrigation management and planning. One of the common methods for measuring the moisture content of the soil is the use of a gypsum block. The use of gypsum blocks in some cases, including the presence of organic matter in soil, may cause an error in the measurement of moisture. For this purpose, a laboratory study was conducte...
متن کاملMonitoring of organic matter and soil salinity by using IRS - LissIII satellite data in the Harat plain, of Yazd province
Current study monitored Electerical Conductivity (EC) as soil salinity index and Organic Matter (OM) in the area of Harat in Yazd, Iran, through remote sensing technology with high spatial and spectral resolution. The images were selected from IRS, LISS III satellites between the years 2008 and 2012. After preprocessing and analyzing the images, the relationship between parameters of (EC) an...
