Soil organic carbon dynamics and its influence on the soil erodibility factor
agrotechnical erosion control measures soil erodibility factor soil erosion soil organic carbon
2015/3/5
The effect of erosion and erosion control measures on changes in the amount of organic matter in soil was studied. We investigated the influence of organic matter inputs into the soil on surface runof...

Secondary forests cover large areas of the tropics and play an important role in the global carbon cycle. During secondary
forest succession, simultaneous changes occur among stand structural attribu...
Organic carbon dynamics and enzyme activities in agricultural soils amended with biogas slurry, liquid manure and sewage sludge
Biogas Slurry Organic Wastes Organic Carbon Dynamics
2013/2/27
The application of organic soil amendments is a common practice for increasing soil fertility and soil organic carbon (SOC) content. In recent years, a new product from biogas production, biogas slurr...
Nitrogen Dynamics of Organic Materials Applied to Paddy Fields: Direct Evaluation Using Organic Materials Labeled with Nitrogen-15

2011/2/24
In this study, 15N-labeled organic materials were used to evaluate the nitrogen (N) dynamics associated with the application of organic materials to paddy fields. The decomposition of three types of o...
Soil Mineral N Dynamics in a Maize Crop Following Different Soil Fertility Amendments in Different Soil Fertility Status in Sub-humid and Semi-arid Regions in Central Kenya
N uptake Organic inputs Nitrate ammonium
2010/11/15
Nitrogen is the major limiting nutrient in crop production and it is also one of the nutrients that is easily lost from the plant-soil system in various ways. Due to this, N supply, N management and N...
