  • 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 Knives: Thermal Spray Case Study

    Adding thermal spray hard-facing to the cutting edge of an agricultural machinery knife is a tried-and-true method of extending the useful life of the product. However, not all thermal spray hard-facing is created equal, as we discovered when we went head-to-head with the competition. The Comparison. It’s common practice in this industry to test machine components under typical field ...

  • 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 ...

  • Removal of acid dyes from aqueous solutions using orange peel as a sorbent material

    An agricultural by-product waste, orange peel, was tested for the removal of four acid dyes from aqueous solutions in batch conditions. As results obtained, kinetics of dyes sorption was time of contact, initial dyes concentration and dyes type dependent. The pseudo second-order reaction rate model adequately described the kinetics of dyes sorption with high correlation coefficients. A. Langmuir ...

  • 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 ...

  • Estimating ground cover of field crops using medium-resolution multispectral satellite imagery

    Remote sensing is useful for estimating plant canopy characteristics, such as leaf area index (LAI) and ground cover (GC). When the source of remote sensing data is medium-resolution satellite imagery, plant canopy characteristics can be estimated for numerous fields within an agricultural region. In this study, a procedure was developed to estimate GC of field crops from medium-resolution ...

  • 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 ...

  • Crops flourish with Scalewatcher

    Water is an essential component of horticulture and agriculture whether it is used for irrigating field-scale vegetables, nursery stock, flowers or fruit.  Where water contains high degrees of calcium, magnesium and sodium, it can cause nutrient deficiency in plants and crops resulting in stunted growth and poor yields. Calcium also blocks irrigation systems and boilers in heated ...

  • Trend of herbicide loads in the river Rhine and its tributaries

    Many policies have been established and actions have been taken to reduce pesticide pollution of surface waters. However, the effectiveness of these initiatives was rarely tested on an empirical basis. This study suggests that evidence on the policy effects can be evaluated by analyzing the temporal changes in the loads rather than the concentrations of active ingredients in rivers. It is shown ...
