Effects of the herbicide imazapyr on juvenile Oregon spotted frogs
Conflict between native amphibians and aquatic weed management in the Pacific Northwest is rarely recognized because most native stillwater‐breeding amphibian species move upland during summer, when herbicide application to control weeds in aquatic habitats typically occurs. However, aquatic weed management may pose a risk for aquatic species present in wetlands through the summer, such as the ...

Dynamics of irrigation management and interlinked agrarian relations: empirical findings from a canal irrigation command in Odisha, India
The literature on the dynamics of irrigation management, in terms of the analysis of interlinked agrarian relations, is very limited. This paper attempts to get a detailed grassroots view of farmers' knowledge of various issues pertaining to the relationship between agrarian structure, land and water. Data from 200 sample cultivators of different farm sizes and 20 landless labour ...

Estimating water use efficiencies for water management reform in Southern Alberta irrigated agriculture
Water use technical efficiency (WUTE) and three definitions of water use economic efficiency (WUEE) were estimated for the four river sub-basins that encompass the 13 irrigation districts in Southern Alberta over a 5-year period: 2004–08. The average level of WUTE varied from 3.5 to 6.2 Mt dam−3. The gross economic value of crop production varied from Canadian (C)$345 to ...

Assessing quality, content, and accessibility of web information about plant biotechnology
The ability to obtain reliable information is critical for decision makers. We examined sources of information about plant biotechnology available on the internet to identify credible, high calibre websites. Google–based searches were performed using: 'plant biotechnology', 'plant genetic engineering', 'genetically modified organisms', 'GMO', 'living modified organisms' and 'LMO'. Lists of ...

AquaCrop model simulation under different irrigation water and nitrogen strategies
On a global scale, irrigated agriculture consumes about 72% of available freshwater resources. Deficit irrigation can be applied in the field to save irrigation water and still lead to acceptable crop production. The AquaCrop model is a simulation model for management of irrigation and nitrogen fertilizer. This model is a new model that is accurate, robust and requires fewer data inputs ...

Pesticide Data Compensation in the EU and Canada
The European Union in recent years has promulgated new regulations to set forth the procedures by which pesticides (called biocides and plant protectants in the EU) are registered and how companies can address issues related to the citation and compensation of data submitted that support those pesticide registrations. Canada also recently issued regulations setting forth new requirements on how ...

A Commercial Case Study from A & A Worm Farm Waste System
We were contacted by the business development manager of a large production plant that employed hundreds of employees onsite. She was looking for practical and cost efficient ways to implement the company’s new environmental policy and to improve the company’s reputation as a responsible corporate citizen. She had identified waste management as a potential area for improvement. After ...

Agriculture minimum temperature
Agriculture minimum temperature Prediction of minimum temperature and frost damage is a common method and important application in the field of agriculture like outdoors crop growth. In particular those areas where vegetation can be exposed to low temperatures, frost can be disastrous for young vegetation or fruits.When the IR net radiation can be measured with the LP Net 14 four component net ...

Effects of repeated pulsed herbicide exposures on the growth of aquatic macrophytes
Many contaminants are released into aquatic systems intermittently in a series of pulses. Pulse timing and magnitude can vary according to usage, compound‐specific physicochemical properties, and use area characteristics. Standard laboratory ecotoxicity tests typically employ continuous exposure concentrations over defined durations and thus may not accurately and realistically reflect the ...

Effects of bisphenol A on growth and nitrogen nutrition of roots of soybean seedlings
Bisphenol A (BPA) is an environmental endocrine disruptor that seriously threatens ecological systems. Plants are the primary producers in ecological systems, but little information is available concerning the toxic effect of BPA on plants. In the present study, the effects of BPA on the growth and nitrogen nutrition of roots of soybean seedlings were investigated by using a root automatic scan ...

Threshold velocity of pollination in urban area of the city of Brno
Wind velocity directly influences pollen release rate from mother plants and subsequently, the transport of pollen grains. The threshold velocity of pollination is defined as the lowest wind velocity with evidence of pollen concentration above the threshold pollen concentration. Only a limited number of published papers deal with the relationship between wind velocity and pollen concentration. ...

Composting Process and Organic Fertilizers Production
Illustrated explanation of two broad stages that are usually applied in most composting facility. First, composting process that convert raw compost into mature compost. Second, organic fertilizers production that convert mature compost into granulated fertilizers. Feedstock for composting stage can be farm and animal husbandry wastes, biomass from plants, and biodegradables that have been ...

Production of biodiesel from pentaclethra macrophylla seed oil
In the present work, the potentials of pentaclethra macrophylla (Africa oil bean) seed oil (PMSO) are evaluated for the first time as a feedstock for biodiesel. Methyl (PMFAME) and ethyl (PMFAEE) esters of PMSO were produced by standard transesterification procedure using potassium hydroxide (KOH) as catalyst and their qualities determined. Gas chromatography mass spectrometry (GCMS) runs of the ...

An experimental approach to compare carbon sequestration rate of four species of legume used as biological façade
Vegetation played an important role in reducing carbon concentration of the environment. Instead of planting horizontally, we attempted to look at planting leguminous plant vertically as biological façade. In tropical climate as in Malaysia, public sensitivity in vertical planting is mostly for aesthetic purposes. This research is focused on selecting vertically grown plant from the point of ...

Adsorption of ammonium using waste activated sludge from palm oil mill effluent treatment plant
Low cost adsorbent was prepared using waste activated sludge (WAS) from a palm oil mill effluent (POME) treatment plant, and used to adsorb ammonium from aqueous solution. The effect of initial concentration, temperature, pH and adsorbent dose was studied in batch test to determine the kinetic and thermodynamic properties. The results showed that the uptake of ammonia increased with an increase ...

Integrated management of diluted distillery effluent and fly ash as a potential biofertiliser: a case study on the vegetative growth and chlorophyll content of the marigold plant, Tagetes patula
The distillery is one of the most polluting industries having high BOD and COD. Apart from the organic content, distillery effluent contains macronutrients such as nitrogen and potassium whereas fly ash produced by thermal power plants contains micronutrients such as iron, copper, manganese, zinc and boron essential for the proper growth of plants. Recently, ferti–irrigation in some states has ...
