Competitiveness and environmental policies for agriculture: testing the Porter hypothesis

Porter hypothesis suggests tougher environmental regulations could spur technological growth, leading to an increase in productivity of market outputs, simultaneously providing greater environmental protection. This study tests the Porter hypothesis in US agriculture using state level data from 1973 through 1996. Luenberger productivity indexes, which are dual to the profit function and do not ...

Pilot Test for Dinoseb Reduction at an Agricultural Facility

Site Summary Dinoseb (2-sec-butyl-4,6-dinitrophenol) is a phenolic herbicide used on soybeans, vegetables, fruits and nuts, citrus,and other field crops for the selective control of grass and broadleaf weeds. It is also used as an insecticide in grapes,and as a seed crop drying agent. In 1986 dinoseb was banned as a commercially available product in the U.S. becauseof the potential ...

HRC Pilot Test Reduces Fertilizer Contamination at an Agricultural Facility

Site Summary Ammonia nitrate is the most common chemical used in fertilizers, providing nitrogen to plants for growth. Dichloropropane (DCP) has also become popular in agriculture as the most common pesticide sprayed on fruit and nut crops to control nematodes. When released into groundwater, nitrate and DCP can be hazardous to human health. A distributing facility in Northern California housed ...

A test of agricultural labour market efficiency in the Gezira scheme, Sudan: a production function approach

This study is concerned with testing the efficiency of the rural labour market in the Gezira scheme. One hundred and fifty respondents were randomly selected through a field survey during the 2003?2004 season. A Cobb-Douglas production function was fitted to the data. The results indicated that labour markets in Gezira do not behave as predicted by the neoclassical theory. Labour allocations are ...

Agricultural Residuals Drive Producer-Owned Energy

Farmer-owned renewable energy enterprises are increasing rapidly — with alternative fuels such as biodiesel, ethanol and distiller’s grains becoming mainstream. MINNESOTA is home to 16 ethanol plants generating approximately 550 million gallons per year. Most of these new facilities are producer-owned. Many others are under construction or are in the planning process. In 2005, Minnesota farmers ...

Physical Contaminant Testing Of Composts

Changes are in progress in multiple countries on weight-based limits for physical contaminants in composts. The net effect may be higher quality compost products. Maintaining and improving compost product quality is vitally important for ensuring continued confidence in organic waste recycling industries around the world. One quality criterion of particular interest from the general ...

The essential oils in agriculture as an alternative strategy to herbicides: a case study

In this study we investigated the allelopathic effect of some essential oils extracted from aromatic plants to inhibit weed seed germination. The study was performed to evaluate the potential genotoxic effect of lavender on Vicia faba root meristems by genotoxicity tests (comet assay and micronuclei test) and to evaluate microbial diversity fluctuation by Restriction Fragment Length Polymorphism ...

Low-tech options for chicken manure treatment and application possibilities in agriculture

SUMMARY: Problems related to chicken manure disposal are a relevant issue in many countries of Asia due to the constantly increasing demand for chicken products. An application without treatment or non-appropriate disposal can become risky for environment and humans. Simple treatment techniques which convert the manure into valuable fertilizer are needed. A low-tech option is currently under ...

A comparison of the herbicide tolerances of rare and common plants in an agricultural landscape

Declining plant biodiversity in agroecosystems has often been attributed to escalating use of chemical herbicides, but other changes in farming systems, including the clearing of seminatural habitat fragments, confound the influence of herbicides. The present study introduces a new approach to evaluate the impacts of herbicide pollution on plant communities at landscape or regional scales. If ...

Comparing RGB-based vegetation indices with NDVI for agricultural drone imagery

Abstract Agribotix conducted a post hoc test of two vegetation indices, VARI and TGI, that used only the three visible-band signals from an unmodified CMOS camera. The results were compared to NDVI, which is generally considered to be a reliable measure of field health and the underlying RGB image. While the results are somewhat encouraging in limited cases, it is clear that neither VARI nor ...

A Concentric Analysis of the Impact of Urbanization on the Threatened European Tree Frog in an Agricultural Landscape

Abstract: Pond-breeding amphibians are affected by site-specific factors and regional and landscape-scale patterns of land use. Recent anthropogenic landscape modifications (drainage, agriculture intensification, larger road networks, and increased traffic) affect species by reducing the suitable habitat area and fragmenting remaining populations. Using a robust ...

Assessing the prediction capacity of an agricultural supply positive mathematical programming model

In this paper, the calibration and prediction capacity of a supply response positive mathematical programming model (PMP) for the Alentejo region are evaluated. The model is calibrated with prices and agricultural subsidies of the base year (2000), using the specification rules of the cost function standard, Paris standard, average cost and exogenous elasticities. Then, the model is utilised for ...

The transport of three emerging pollutants through an agricultural soil irrigated with untreated wastewater

The aim of this work was to determine the mobility of naproxen, carbamazepine, and triclosan through a wastewater-irrigated agricultural soil. Transport experiments were carried out using undisturbed soil columns taken at 10 and 40 cm depths. The mobilization of the pollutants was evaluated using two hydrological regimes transient flow for superficial columns and steady-state conditions for the ...

CRISPR is coming to agriculture — with big implications for food, farmers, consumers and nature

Gene editing offers dramatic advances in speed, scope and scale of genetic improvement. It also offers an opportunity for more nuanced GMO governance. Very few technologies truly merit the epithet “game changer” — but a new genetic engineering tool known as CRISPR-Cas9 is one of them. Since we first developed the ability to alter the genetic material inside a plant or animal in ...

Towards new modes of governance of the research–development continuum to facilitate the dissemination of agricultural innovations in a mountainous province of northern Vietnam

The mountainous regions of northern Vietnam have, thus far, failed to share the impressive economic development that has blessed the rest of the country in the past decade. Despite the multiplicity of Research and Development (R&D) projects working there with the common objectives of agricultural development and poverty alleviation, lack of coordination among projects can limit the effectiveness ...

Hot spots in animal agriculture, emerging federal environmental policies and the potential for efficiency and innovation offsets

In North America and Northern Europe, high livestock densities in concentrated areas (hot spots) have led to manure surpluses, which have resulted in water pollution problems. Using the emerging policy objectives for animal waste in the European Union and the USA as a backdrop, this paper discusses the impact of environmental regulation on farm profits. A theoretical model of the farm is ...
