In direct seeding systems, soil strength variability and crop residues increase the difficulty of seeding operation. Especially when trying to achieve uniform seeding depth that will result in reliable seed germination and plant emergence. An advanced improvement has been accomplished using direct seeding systems. However, some problems still exist in soil-machine interaction due to various rea...

Forest fire is an important occurrence in western landscapes where it helps drive ecosystem processes, and prescribed a common forest management strategy. An initial consequence of burned ground with reduced biodiversity. Numerous studies have documented how forests recover after terms plant regeneration animal colonization, but little known the ecological roles fungi play this process. Pyrophi...

Soil microorganisms are largely responsible for biogeochemical fluxes in the terrestrial biosphere that effect ecosystem productivity and alter global climate patterns. Though the importance of soil microorganisms is easy to state, little is known about interactions between microbes necessary for the production of ecosystem-scale fluxes. Furthermore, measurement of biogeochemical fluxes at the ...

This paper describes the relationship of forest soil dryness and antecedent rainfall with suspended sediment (SS) yield due to extreme rainfall events and how this relationship affects the survival of forest plants. Several phenomena contribute to this relationship: increasing evaporation (amount of water vapour discharged from soil) due to increasing air temperature, decreasing moisture conten...
