Molecular geochemistry of soil organic matter by pyrolysis gas chromatography/mass spectrometry (GC/MS) technique: A review
Soil organic matter (SOM) is arguably the most complex and least understood component of soils. To analyze SOM structure and reduce SOM large structural heterogeneity, different components of SOM need to be separated into entities that differ in terms of source, composition, and turnover. Pyrolysis-gas chromatography/mass spectrometry (Pyrolysis-GC/MS) is to present the most effectual approach in the study of the...

Partial balance of N, P and K in a sole millet crop on a sandy loam soil of Northeast Nigeria
A study was conducted on nutrient dynamics through partial N, P and K balances during 2005 growing season. The treatments involved three levels of farmyard manure (FYM: 2.5, 5.0 and 7.5 tons/ha) combined with half (N30P15K15 kg/ha) and full (N60P30K30 kg/ha) recommended rates of NPK fertilizer and sole recommended rates of FYM (7.5 tons/ha) and NPK (N60P30K30 kg/ha) and a control. The experiment was laid out in RCB...

Isolation of microorganism from soil contaminated with degraded paper in Jharna village Sharma Richa*, Chandra Subhash and Singh Amrita
Pulp and paper mills are categorized as a core sector industry and are the fifth largest contributor to industrial water pollution. The pollutant, discharge from the pulp and paper industry, affect all aspects of the environment such as water, air and land. Various studies have reported detrimental effects of pulp and paper mill effluent on animals living in water bodies receiving the effluent. The effects are...

Assessing soil amendment potentials of Mucuna pruriens and Crotalaria juncea when used as fallow crops
This research was carried out to assess the soil amendment potentials of Mucuna pruriens andCrotalaria juncea when used as fallow crops. The research made use of randomized complete block design (RCBD) with three treatments replicated three times. The study revealed higher mean levels of percentage nitrogen, phosphorus, potassium, percentage organic carbon and soil pH after incorporation as compared to...

Evaluation of the effect of Ficus thonningii (blume) on soil physicochemical properties in Ahferom district of Tigray, Ethiopia
A study to evaluate the effect of Ficus thonningii (Blume) on soil physicochemical properties was conducted in Ahferom district of Tigray, Ethiopia. For the soil physico-chemical property study, two factors (distance from the tree trunk and soil depth from the ground level) arranged in randomized complete block design (RCBD) with six replications was involved. The distance factor had three levels viz. at half...
