Nitrous oxide (NrO) production in aerobic, intact soil cores collected from two forest sites was partitioned into different sources of N,O by subjecting soils to specitlc inhibitors during short-term incubations. We used acetylene (IO Pa) to selectively inhibit N,O production by nitrifiers, 100 kPa (100% v/v) 0, to inhibit N,O production by denitrifiers, and sterilixed soil to evaluate chemical...

In recent years, salinization of soil is one the challenging environmental concerns occurring all over world. The effects concentration salt can be detected in both natural (primary) as well man-made (secondary) environment. This due to massive urbanization and industrialization coastal regions, Soil salinity may lead degradative changes composition water resources, loss fertile soil, biodivers...

The idea that human health is tied to the soil is not a new one. As far back as circa 1400 BC the Bible depicts Moses as understanding that fertile soil was essential to the well-being of his people. In 400 BC the Greek philosopher Hippocrates provided a list of things that should be considered in a proper medical evaluation, including the properties of the local ground. By the late 1700s and e...

The Isle of Rum, Inner Hebrides, has an impoverished earthworm fauna as the soils are generally acidic and nutrient-poor. Species associated with human habitation are found around deserted crofting settlements subjected to “clearances” in the mid-19th century and at Kinloch, where a large volume of fertile soil was imported from the mainland around 1900. Earthworms, and the dew worm Lumbricus t...

Forests in lowland Bolivia suffer from severe deforestation caused by different types of agents and land use activities. We identify three major proximate causes of deforestation. The largest share of deforestation is attributable to the expansion of mechanized agriculture, followed by cattle ranching and small-scale agriculture. We utilize a spatially explicit multinomial logit model to analyz...

Plant life and food production for human closely depend on fertile and healthy soil. Knowledge about qualitative properties of soil and its potential production can contribute us in the plantation, fertilization, utilization and land management. In addition, Rangelands cover a very large portion of the earth's surface and play an important role in food security and other ecosystem services. The...

The article talks about the process of erosion and its damage to environment. It has been determined that as develops, natural processes within soil are disturbed, upper fertile layer is destroyed. As a result erosion, damaged weakens rate biomass formation changes direction process. This ultimately leads transformation ecological situation. should also be noted paraactive system. Diagnosis for...

OBJECTIVE To assess semen analysis, testicular volume, and hormone levels in fertile and infertile patients with varicoceles and fertile men without varicoceles. DESIGN Retrospective study. SETTING Academic medical center. PATIENT(S) Patients were divided into three groups: fertile men with varicoceles (n = 79), infertile men with varicoceles (n = 71), and fertile men without varicoceles ...
