HINGED JOINT FIELD FENCE HEAVILY GALVANISED
Hinge joint field fence has four wrap knots or joints formed with two vertical stay wires wrap together that give under pressure, then spring back into shape. This hinged knot provides a continuing protection, maximum strength and flexibility of the entire fence fabrics. Hinge joint fence is popularly use in farms, pastures of USA, Canada, South Africa, Australia as field fencing materials. Hinge ...

The European Grassland Butterfly Indicator: 1990–2011
This report presents the European Grassland Butterfly Indicator, based on national Butterfly Monitoring Schemes (BMS) in 19 countries across Europe, most of them in the European Union. The indicator shows that since 1990 till 2011 butterfly populations have declined by almost 50 %, indicating a dramatic loss of grassland biodiversity. This also means the situation has not improved since the ...

Modeling tiller density, growth, and yield of mediterranean perennial grasslands with STICS
A generic crop model (STICS) was adapted (STICS–Grassland) to model growth, yield, and environmental impacts of grasslands in France. It is a semimechanistic model combining equations of physiological processes and mathematical relationships between processes in a daily time step. The Information et Suivi Objectif des Prairies (ISOP; Grassland Information and Objective Survey) application was ...

Ecological zoning of an Andean grasslands (puna) at the manu biosphere reserve, Peru
In the Andean transition area the Manu Biosphere Reserve (MBR), in Peru, located within the Amazon basin, there are natural grasslands which are suffering from human impact, due to heavy grazing activities, jeopardising their Carrying Capacity (CC). To minimise this impact, it was found necessary to understand the participation of the environmental variables and the anthropogenic activities ...

Soil water recharge for grassed and forested land covers on the Oak Ridges Moraine, southern Ontario, Canada
Soil water recharge (R) below 1 m depth was estimated via a 1-d water balance for grasslands, hardwood stands and red pine plantations on the Oak Ridges Moraine (ORM) in southern Ontario, Canada. Annual R values (431–696 mm) were in the order of previous estimates for outcropping sands and gravels on the ORM (∼400 mm); however, they only partially supported hypothesized differences in R ...

Conversion to extensive grassland
The Mitigation Strategy of the measure Conversion to extensive grassland refers to flood prevention and environmental protection also. Flood protection can be achieved by: Increase the infiltration of rainwater by high roughness and preventing soil silting; Reducing the flow velocity of surface run off; The hydrologic-hydraulic effect varies depending on the vegetation, soil condition at ...

When planting trees does more harm than good
Note to anyone who thinks planting trees is the bees’ knees: Grasslands are important, too. With forests disappearing at record rates and the carbon sequestration and other benefits of vegetation getting increasing visibility, tree-planting has become almost an iconic “environmentally friendly” activity. But in some cases it could do more harm than good, according to Iowa State ...

Assessment of pasture biomass with the normalized difference vegetation index from active ground-based sensors
Calculating forage availability is challenging for managers of grazing systems due to the spatial heterogeneity of swards. Remote sensing applications may help to overcome this problem through estimates of biomass made with reflectance data. The objectives of this study were to (i) estimate herbage mass using an active, on-the-go, ground-based, narrow band sensor to calculate the normalized ...

Flood risk for farmer and dyke relocation
The Biosphere Reserve Lower Saxonian Elbe Valley (Biosphärenreservat Niedersächsische Elbtalaue), which was created on the basis of an unanimous decision by the Lower Saxonian State Parliament in 2002, represents Lower Saxony’s contribution to the UNESCO Biosphere Reserve ‘Flusslandschaft Elbe’ (Elbe River Landscape). It stretches for about 100 kilometres south-east of ...

Influence of microbial activity on plant–microbial competition for organic and inorganic nitrogen
Abstract To investigate how the level of microbial activity in grassland soils affects plant–microbial competition for different nitrogen (N) forms, we established microcosms consisting of a natural soil community and a seedling of one of two co-existing grass species, Anthoxanthum odoratum or Festuca rubra. We then stimulated the soil microbial community with glucose in half of the microcosms ...

No-till sequential cropping of summer and fall annual forage species compared with grassland
Summer (SAS) and fall annual species (FAS) can supplement animal forage requirements during times of slow growth of cool-season perennials. A 2-yr experiment was conducted in a perennial grassland (G) at the Reedsville Experimental Farm of West Virginia University to determine herbage accumulation (HA) and quality of two summer and two fall crops (in factorial combination) grown on the same land. ...

Endophyte survival during seed storage: Endophyte–host interactions and heritability
Use of nontoxic endophytes in forage tall fescue [Schedonorus phoenix (Scop.) Holub.] is a preferred strategy to overcome fescue toxicosis. Endophytes are transmitted through the seed, but suffer mortality preferentially to the embryo during storage. Loss of viable endophyte reduces the value of the seed, so increasing storage life would be a benefit. The objectives of this study were to examine ...

Comparison of data from two vegetation monitoring methods in semi-natural grasslands
Two vegetation-monitoring methods were compared: subplot frequency analysis (SF) and visual estimation of percentage cover (VE). Two independent observers collected data from two semi-natural, species-rich grasslands on three different occasions during the growth-season. During the last data collection period, survey times were also recorded. The two different data sets from the two methods were ...

Phytoextraction of Phosphorus-enriched grassland soils
Received for publication February 7, 2008. High soil P contents in agricultural soils in the Netherlands cause excessive losses of P to surface waters. The reductions in P application rates in the present manure policy are not sufficient to reach surface water quality standards resulting from the European Water Framework Directive in 2015. Accordingly, additional measures are necessary to reduce ...

Focal bird species and risk assessment approach for non‐agricultural grassland scenarios in Central Europe
The European Food Safety Authority guideline on risk assessment identifies pesticide exposure scenarios for non‐target wildlife, however this scheme is not applicable to non‐agricultural grassland. For example, different habitats and human utilisation on golf courses attract bird communities that differ from those found in agricultural fields with annual crop cycles. The present study ...

Playing hide and seek below the soil
Below the soil of a diverse grassland area you’ll find a jungle of plant roots. It is also home to a wide variety of bacteria and fungi, of which some are pathogenic and looking for a host in the tangle of roots. It appears that this is much more difficult when there is a larger diversity of plants as the host plant is more able to hide among the varied crowd. Greater plant diversity ...

No-till corn after Bromegrass: Effect on soil carbon and soil aggregates
Grasslands in the Conservation Reserve Program (CRP) in the USA may be converted to grain crops for bioenergy. The effect of no-till conversion of a smooth bromegrass (Bromus inermis Leyss) grassland to no-till corn (Zea mays L.) production on soil organic carbon (SOC) in the western Corn Belt was monitored for over 6 yr. A different 13C/12C isotope signature is imparted to SOC by C4 plants ...
