  • Site-specific nitrogen and plant density management in irrigated maize

    Economic or environmental benefits resulting from variable-rate (VR) application of N and seed are uncertain in irrigated maize (Zea mays L.) systems with high yield potential. We evaluated different plant population and N management strategies in two irrigated maize fields in Nebraska. Inputs were varied according to yield zones derived from yield maps, detailed maps of soil organic matter ...

  • Normalized difference vegetation index and soil color-based management zones in irrigated maize

    Spectral vegetation indices such as the normalized difference vegetation index (NDVI) have been shown to be useful for indirectly obtaining crop information such as photosynthetic efficiency, productivity potential, and potential yield. The objectives of this study were (i) to examine the relationships among NDVI determined early in the growing season, soil color-based management zones (SCMZ), ...

  • Arsenic in irrigated paddy soils

    Natural arsenic pollution of drinking water has been reported from over 70 countries world-wide, affecting an estimated 150 million people (Ravenscroft et. al., 2008). About 50 million of these people live in Bangladesh, 30 million in India and 33 million in six other countries of south and south-east Asia. It has recently been recognised that arsenic-contaminated groundwater used for irrigation ...

  • Effect of deficit irrigation and fertilization on cucumber

    Soil water budgets are essential in determining the proper timing and amount of irrigation. Organic fertilizers can be substituted for commercial fertilizers; however, information is sparse on the interaction of irrigation management and nutrient source on cucumber (Cucumis sativus L.) production. This study evaluated nutrient source and irrigation management on growth and yield of cucumber grown ...

  • A tale of two developments of irrigation: India and USA

    This paper offers a comparative study of economic history of two of the four largest irrigation systems in the world covering a period of about one hundred years, and points out the major lessons learnt from development experiences. This is especially significant since one is a developing country (which was considered a "more developed" irrigation system a century ago) and the other is a ...

  • Jordan water demand management study: on behalf of the Jordanian Ministry of Water and Irrigation in cooperation with the French Development Agency (AFD)

    The Jordanian National Water Master Plan (2004) stipulates water demand management (WDM) as one of the central strategies in achieving a more efficient and cost-effective water use. A new study under the funding mechanism of a regional program, led by the French Development Agency, reviewed and analyzed the situation in different sectors of water consumption, updated information on water values ...

  • Delta Drainage and Irrigation System - Case Study

    Background Delta, British Columbia is located in the Fraser River delta on the shores of the Pacific Ocean, just south of the City of Vancouver. Delta comprises mostly agricultural land, with typical ground elevations near sea level. Levees protect the area from potential floods from the Fraser River and tidal surges from the Pacific Ocean. Of the 13,500 hectares (ha) watershed, ...

  • Organisational strategies in situations of water scarcity: self-administered irrigation systems in Mexico

    A systematic comparison of in-depth case studies of self-organisation for the administration, maintenance and construction of irrigation systems seems to offer interesting and suggestive results in terms of gaining familiarity with and analysing the capacity for self-organisation, as well as for discovering and classifying different organisational responses to similar types of problems. This ...

  • Smart Series-Odor Management

    Tackling odors at composting facilities is a manageable task made simpler by inventorying and treating all sources and tapping into technology advances. Perhaps one of the most difficult realities that had to be faced 15 to 20 years ago by the composting universe is that the phrase, “odor-free” - at least when it comes to composting - is probably an oxymoron. Feedstocks that biodegrade within the ...

  • Water justice: exploring the social dimensions of new irrigation technologies in northern Victoria, Australia

    Water resource management is one of the most pressing human and environmental challenges of the 21st century. Technological approaches to improving the management of water feature prominently, with technology positioned as the solution to issues of competing interests and the achievement of water savings. This paper analyses the social dimensions of a regional-level irrigation technology, ...

  • Development of a decision support system for small reservoir irrigation systems in rainfed and drought prone areas

    An integrated computer program called Cropping System and Water Management Model (CSWM) with a three-step feature (expert system—simulation—optimization) was developed to address a range of decision support for rainfed farming, i.e. crop selection, scheduling and optimisation. The system was used for agricultural planning with emphasis on sustainable agriculture in the rainfed areas through the ...

  • Spatial mapping of complex turfgrass sites: site-specific management units and protocols

    Site-specific management units (SSMUs), similar in soil, plant, and irrigation requirements, are foundational to efficient management in precision agriculture. This concept is applied to management of complex turfgrass sites to improve irrigation practices. An experimental mobile unit mapped two golf fairways' turfgrass (Paspalum vaginatum SW.; ‘Salam’) in Naples, FL in summer 2006 on a 2.5 m ...

  • Assessment of aquacrop, cropsyst, and WOFOST models in the simulation of sunflower growth under different water regimes

    This work compares the performance of AquaCrop, a crop simulation model developed by FAO, with that of two well established models, CropSyst and WOFOST, in simulating sunflower (Helianthus annuus L.) growth under different water regimes in a Mediterranean environment. The models differ in the level of complexity describing crop development, in the main growth modules driving the simulation of ...

  • An overview of microfinance and the environmental sustainability of smallholder agriculture

    The interest and growth in microfinance have burgeoned during the last two decades with the involvement of both private and public sector agencies. As a result of the interest in this sector, microfinance services have grown rapidly. However, little attention has been given to the environmental impacts of microcredit, or ways to mitigate those impacts. This is of particular concern in a rural ...
