The usage of grassland significantly affects the microbial and biochemical parameters soil epipedons. use grasslands (by mowing, grazing, mowing grazing) dominance bacteria in abundance relative to fungal populations. This was particularly noticeable when manual applied. In general, highest number microorganisms occurred during spring summer, which should be associated with intensity growth roo...

The purpose of our investigation was to clarify the effects of agriculture on the process of loss of litter at the periphery of a farmland. This study revealed the generation process of an ecologically unusual phenomenon that is observed around cropland in semi-arid regions. We hypothesized that the vegetation around a farmland cannot supply plant litter to the ground surface because the ecolog...

nowadays, establishment and maintenance of turfgrasses due to high water requirements was faced with serious doubts. hence, screening of drought resistance native grasses, and introduces them as turfgrass is not only effective in reduction of water usage but can also preserve plant gene pools of the country. in the present experiment, wheat grass and bromus as two native grasses were compared w...

This study is focused on the vegetation of seminatural dry grasslands. These grasslands are valuable with large biodiversity; however, their long-term preservation requires regular conservation management. report demonstrates results a 13-years mowing experiment, designed to suppress spread an unpalatable grass species, Calamagrostis epigejos. The site was located in mid-successional grasslands...

Restrictions on the use of synthetic molluscicides highlight importance developing alternative control methods. Nevertheless, biocontrol agents can be costlier and less effective than counterparts. One means increasing efficacy population suppression is to combine inundative biological with habitat management reduce growth target pests. Vineyards in cool, wet climate western England suffer from...

Abstract Northern Ireland dairy farmers (n = 174) were surveyed to identify key silage-making practices, and factors perceived influence the quality of grass silage made on their farms. The majority (65%) harvested for three times/year: 62% normally used a contractor, while 47% routinely additive. Delays mowing delays harvesting due adverse weather or poor ground conditions have large very impa...

The degree to which biodiversity may promote the stability of grasslands in the light of climatic variability, such as prolonged summer drought, has attracted considerable interest. Studies so far yielded inconsistent results and in addition, the effect of different grassland management practices on their response to drought remains an open question. We experimentally combined the manipulation ...
