Soil Microbial Biomass Carbon and Nitrogen in Himalayan Rangeland of Eastern Nepal: A Comparison between Grazed and Non-grazed Rangelands
Soil microbial biomass plays an important role in nutrient transformation in terrestrial ecosystems. Microbial biomass is also an early indicator of changes in total soil organic carbon. Thus, the main objective of this study was to identify and quantify the present status of soil microbial biomass carbon and nitrogen with various management practices in Himalayan rangeland. To meet the aforeme...
متن کاملDynamical systems modelling of the interactions of animal stocking density and soil fertility in grazed pasture
To examine the long term e ects of fertiliser application on pasture growth under grazing a mathematical representation of the pasture ecosystem is created and analysed mathe matically From this the nutrient application level needed to maintain a given stocking rate can be determined along with its pro tability Feasible stocking levels and fertiliser application rates are investigated and the o...
متن کاملSoil Carbon and Nutrient Changes Associated with Deforestation for Pasture in Southern Costa Rica
We assessed the effects of deforestation on soil carbon (C) and nutrient stocks in the premontane landscape near Las Cruces Biological Station in southern Costa Rica, where forests were cleared for pasture in the mid-1960s. We excavated six soil pits to a depth of 1 m in both pasture and primary forest, and found that C stocks were ~20 kg C/m in both settings. Nevertheless, soil dC suggests ~50...

متن کاملStudy of Changes in Soil Moisture and Salinity Under PlasticMulch and Drip Irrigation in Pistachio Trees
In this study, changes in soil moisture and salinity contents in drip irrigation combined with white and black plastic mulches compared to no mulch (control) was evaluated. The experiment was carried out in two commercial pistachio orchards (Ohadi cultivar) with irrigation frequencies of 8 to 12 days with a total water consumption 4100 and 6170 m3ha−1. The study was conducted in a complete rand...
