Sustainable use of regional land should correspond with the level of economy development and its most important aspect is coordinating the relationship between the urbanization and agricultural land protecting.
The decline of methane oxidizing activities in gray forest soil upon its conversion into arable land was shown to be caused by major changes in biotic and physicochemical properties of soil.
Microbial biomass and the content of microbial carbon in humus (Cmic /Corg) decreased in the following order: soils under forest cenoses-mowed meadow-10-year arable land-46- and 75-year arable land.
The pattern of their vertical distribution in areas with tree and shrub vegetation differs from that in arable land.
Effect of mechanical disturbances on nematode communities in arable land
Measurements showed significantly higher values of saturated hydraulic conductivity for topsoils in wetlands (6.2 m day-1 on average) compared to mown grasslands (1.47 m day-1) and arable land (0.79 m day-1).
littoralis were light-trapped in June, July, August, and September in 1997 and 1998 in the edge of farming land in Assiut (Egypt).
The disease is spread solely through an intermediary named oncomelania, so its spread of schistosomiasis can be controlled by properly designing water intakes which prevent oncomelania from entering farming land or residential areas.
In Indonesia, paraquat products play an important role in controlling weed in plantation estates, small-holders farming land and potentially in tidal swamp areas to be converted to tidal rice farming.
Human-induced soil erosion has already affected all of the potential farming land in the Tarija basin/South Bolivia.
On the other hand, great losses were determined in farming land, olive groves, forest and in the marsh and lagoon system.
