Our planet is facing food scarcity due to a rapidly growing population. Hence, production and sources must adapt accommodate population changing climate in addition being produced year-round small space with minimal inputs. Brassicaceae microgreens (BM) have short growth cycle can quickly grow minimum inputs area year-round, which make them an ideal candidate diversify global nutrition change urbanization. There interest incorporating BM into daily diets as source of phytochemicals other...
Abstract Fertilizer nitrogen (N) contributes to ammonia ( NH 3 ) emissions, which European Union member states have committed reduce. This study focused on evaluating ‐N loss from a suite of N fertilizers over multiple applications, and gained insights into the temporal seasonal patterns urea in Irish temperate grassland using wind tunnels. The evaluated were calcium ammonium nitrate CAN ), with stabilizers N‐( n ‐ butyl thiophosphoric triamide NBPT dicyandiamide DCD + maleic itaconic acid...
Nitrogen (N) losses are a major environmental issue. Globally, crop N fertilizer applications excessive, and use efficiency (NUE) is low. loss represents significant economic to the farmer. NUE difficult quantify in real time because of multiple chemical–biological–physical factors interacting. While there much scientific understanding interactions plant–soil system, little formal expression knowledge farm practice. The objective this study was clearly define controlling wheat production,...
Soil pore structure influences hydraulic conductivity and saturation regimes. The influence of soil structure, mechanisms overland flow on the form phosphorus (P) loss is not fully understood. Models P transport assume either excess (SE) or infiltration (IE) as triggering mechanism. SE runoff may lead to higher dissolved losses, due a) lower applied energy hence less physical separation particulates, and/or b) greater mobilization from sorbed reserves during antecedent saturation....
To investigate bacterial and fungal community structure during degradation of varying concentrations (0-5000 mg kg(-1) ) the polycyclic aromatic hydrocarbon (PAH) fluoranthene in presence or absence tomato plants.Fluoranthene amended unamended growing media, with without a plant, were incubated pots glasshouse for 30 days. Fluoranthene concentration was quantified using GC-FID, while investigated trflp arisa, respectively. The abundance two ring hydroxylating dioxygenase genes measured qPCR....
To manage greenhouse gas emissions, directives on renewable energy usage have been developed by the European Commission with objective to reduce overall emissions 40% 2030 which presents a significant potential for sources. At same time, it is challenge these technologies can only be solved integrated solutions. Carbon capture and storage combined geothermal could serve as novel approach CO2 at time facilitate some of negative impacts associated fossil fuel-based power plants. This study...
Abstract Development of novel methods to inhibit ammonia (NH 3 ) volatilization losses has become a strong research focus reduce the environmental impact agriculture and as potential area for growth in fertilizer industry. European Union legislation on regulation NH emission from mineral fertilizers after 2030, will only allow urea with reduced emissions by at least 30% remain use. The recent increase prices also created renewed impetus curb these losses. This paper details results an...
In the last century, breeding programs have traditionally favoured yield-related traits, grown under high-input conditions, resulting in a loss of genetic diversity and an increased susceptibility to stresses crops. Thus, exploiting understudied resources, that potentially harbour tolerance genes, is vital for sustainable agriculture. Northern European barley germplasm has been relatively despite its key role within malting industry. The Heritage Barley collection (ExHIBiT) was assembled...
Abstract In temperate grassland, urea has been shown to have lower nitrous oxide emissions compared ammonium nitrate‐based fertilizer and is less expensive. However, nitrogen (N) loss via ammonia volatilization from raises questions regarding yield performance efficiency. This study compares the N offtake of grass fertilized with urea, calcium nitrate ( CAN ) treated urease inhibitor ‐( n ‐ butyl) thiophosphoric triamide NBPT at six site‐years. Five annual rates (100–500 kg N/ha) were...
Core Ideas CAN is a widely used form of straight N in Western Europe. Urea+NBPT consistently delivered equal yields and uptake compared with CAN. had higher than urea 2 6 site‐years, but were not different. NBPT increased the site‐years no effect on yield. Urea+DCD lower yield 3 4 respectively. In temperate grasslands, source influences greenhouse gas emissions. Nitrification hydrolysis inhibitors can reduce these losses. The objective this study was to evaluate impact source, urease...
Four horses and one pony, ranging in age from to 11 years, were diagnosed with two different types of odontoid peg fractures. Their clinical signs included reluctance move the neck head, dullness, abnormalities gait. Radiography was essential for diagnosis, method treatment varied depending on severity neurological signs, intended use horse, financial constraints. Optimal requires a technique that allows decompression, anatomical alignment, stabilisation fracture. If (neurological) are not...
Winter wheat (Triticum aestivum L.) is an important cereal crop in the temperate climates of western Europe. Root system architecture a significant contributor to resource capture and plant resilience. However, impact soil type on root (RSA) field structured soils yet be fully assessed. This work studied development growth using deep cultivation (250 mm) during tillering phase stage (Zadock 25) winter across three types. The sites contrasting types covered geographical area UK Ireland...
Abstract. The management of agricultural soils during crop establishment can affect root development due to changes in the soil structure. This paper assesses influence tillage depth (250 mm, 100 and zero tillage) traffic (conventional tyre pressure, low no traffic) on wheat system architecture winter (Triticum aestivum L.) tillering flowering growth stages (GS) at a long-term trial site. study revealed that zero-tillage systems increased yield through significantly greater biomass...
Microgeneration of electricity using solar photovoltaic (PV) systems is a sustainable form renewable energy, however uptake in Ireland remains very low. The aim this study to assess the potential community-based roof top PV microgeneration system supply grid, and explore crowd funding mechanism for community ownership projects. A modelled project was developed: load profiles 68 residential units were estimated; designed; an network model, based on real supplying town its surrounding areas,...
Managed grasslands influence global warming by the exchange of greenhouse gases (GHG) like carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4). Application animal waste, such as slurry, rich in inorganic nitrogen (N), may escalate soil processes thus GHG emissions, particularly organic systems that rely on input manures without chemical inputs. The objective this study was to evaluate mitigation potential biological amendments might be relevant their effects N leaching over a 2-month...
Data centres, though a necessary part of modern society, are being stigmatised for consuming vast amounts electricity their operational and cooling needs. Due to Ireland’s reliance on fossil fuels meet the increased energy demand data centres contributing significantly total carbon emissions. As much this is expelled from as waste heat energy, potential recycling some wasted was explored using environmentally friendly systems recent publications. The recovered applied in vertical...
