  • GoRoSoBo: an overall control diagram to improve the efficiency of water transport systems in real time

    Agriculture plays an important part in the food chain and water resources for agriculture are essential. A problem is that the water transport systems present low efficiencies in practice. Crop yields must be optimized, and the goal of an operational water manager is to deliver water to irrigation sites accurately and efficiently. In order to fulfill this objective, we propose a centralized ...

  • The impact of climate change and soil salinity in irrigation water demand on the Gaza Strip

    The presented work analyzes the potential impacts of the temperature, precipitation changes and water salinity on agricultural water demand. The study was carried out on five representative orchard crops (olive, palm, grapes, citrus and guava) that cover around 83% of the orchard farms in Gaza Strip. To achieve this goal, CropWat modeling software version 8.0 is used to calculate the ...

  • Determination of a critical nitrogen dilution curve for spring wheat

    Plant-based diagnostic tools of N deficiency can be based on the concept of critical N dilution curves describing whole-plant critical N concentration (Nc; g kg–1 of dry matter [DM]) as a function of shoot biomass (W; Mg DM ha–1). This has been tested for several crops, including winter wheat (Triticum aestivum L.) but has not been tested for spring wheat. Our objectives were to determine a ...

  • Agricultural Use of Different Residual Waste Composts - Current Situation and Experiences in France

    ABSTRACT Quality standards have been recently established in France for sewage sludge composts and other urban composts (greenwaste, biowaste and municipal solid waste composts). These standards allow to guarantee the innocuousness of the composts. Other standards have been defined in order to predict the compost effects on soil properties: the index of biological stability (ISB), based on ...

  • Aerial color infrared photography to optimize in-season nitrogen fertilizer recommendations in winter wheat

    Remote sensing in the form of aerial color infrared (CIR) photography has been shown to be a useful tool for in-season N management in winter wheat (Triticum aestivum L.). The objectives of this study were (i) to develop a methodology for predicting in-season optimum fertilizer N rates for winter wheat at growth stage (GS) 30 directly from aerial CIR photography and (ii) to quantify how the ...

  • The Importance of Scales in the Agricultural & Farming Industry

    Weighing scales are essential and necessary equipment required for a wide range of applications. Whether intended for personal, industrial or commercial use, they serve one important function – providing accurate weight measurements for varied loads. In the agricultural sector, scales are indispensable tools and without them, it would be almost impossible to manage farms or carry out trade! ...

  • New approaches are needed for another Green Revolution

    Twenty-first century agriculture needs low-input advances like the System of Rice Intensification, says Norman Uphoff. According to the principle of diminishing returns, continuing to produce something in the same way, with the same inputs and technology, ...

  • Cropland management techniques for carbon storage

    The Kyoto protocol of 1997 recognises cropland management as a carbon sequestration strategy which may help to mitigate climate change. Under the protocol, ratified by the EU in 2002, member states are obliged to reduce the sum of their emissions of greenhouse gases to 5 per cent below their 1990 levels. Appropriate cropland management may help member countries meet the overall EU emissions ...

  • Cannabis Irrigation-Israel

    Getting to Know Cannabis Farming Israel’s agricultural industry is ripening for the beginning of medical cannabis export, with the expected passage of medical export legislation by the end of the year. The timing is particularly fruitful for growers who are interested in succeeding in a new venture that is still in its infancy. The rewards are also high: Israel’s Health and ...

  • Carbon Sequestration: Addressing Climate Change and Food Security through Sustainable Agriculture

    Introduction To meet the demands of a growing, increasingly urban global population (approximately 9 billion by 2050), the World Bank calculates that global food production must increase by 70% in the next 35 years. This is a great challenge not only because of the volume of food that must be produced, but because agricultural conditions will not remain constant or predicable ...

  • The Nature of the New World

    We recently entered a new century, but we are also entering a new world, one where the collisions between our demands and the earth’s capacity to satisfy them are becoming daily events. It may be another crop-withering heat wave, another village abandoned because of invading sand dunes, or another aquifer pumped dry. If we do not act quickly to reverse the trends, these seemingly isolated events ...

  • Unlocking the potential of poultry manure

    The poultry industry is one of the largest and fastest-growing agro-based industries in the world. At the same time, the growth brings along a number of environmental problems. One of the major environmental problems is the accumulation of large amounts of wastes, e.g. manure. In order to mitigate these problems new economically sustainable technologies are needed. Manure has often been ...

  • Cost-Benefit Analyses: Exploring the Economics of On-Farm Composting

    When exploring the merits of on-farm composting, the question most often raised is: What are the economics? How do the savings or revenues from on-farm composting compare to the costs? Of course, the answer is the ever present “it depends.” Expenses, resources, revenue opportunities, environmental constraints and circumstances vary greatly from one farm to the next. Most people would agree that ...

  • How Much Will it Cost to Save Our Economy’s Foundation?

    During the past two summers, Pakistan was hit with catastrophic floods. The record flooding in the late summer of 2010 was the most devastating natural disaster in Pakistan’s history. The media coverage reported torrential rains as the cause, but there is much more to the story. When Pakistan was created in 1947, some 30 percent of the landscape was covered by forests. Now it is 4 percent. ...

  • Could food shortages bring down civilization?

    “In early 2008, Saudi Arabia announced that, after being self-sufficient in wheat for over 20 years, the non-replenishable aquifer it had been pumping for irrigation was largely depleted,” writes Lester R. Brown in his new book, Plan B 4.0: Mobilizing to Save Civilization (W.W. Norton & Company). “In response, officials said they would reduce their wheat harvest by one eighth each year ...

  • LED or HPS for Growing Cannabis?

    “What lighting source should I use for my licensed cannabis grow?”; “I am comparing LED to HPS for my cannabis operation. Which source do you recommend?” These are questions people ask me almost on a daily basis. We have covered this question in past posts on our blog, like this one by our very own head of marketing: LEDs vs ...

  • 7 Species of Bees Added to Endangered List

    Introduction For the first time in history, several American bee species have been classified as endangered. There are many factors that have contributed to the decline in bee populations in recent years, with climate change being at the root of many of these issues. In order to save the dwindling number of bees, we must implement the mitigation and management plans that are in place, ...

  • Pragmatic farm composters forge new path to resource recovery

    AG CHOICE is an on-farm composting operation located in the scenic countryside of Andover, New Jersey. On the drive to tour their site, it was astounding just how much of New Jersey, our most densely populated state, is still rural. Jay and Jill Fischer operate the two-year-old facility, which is one of a kind in New Jersey. Jay also owns and operates a sawmill in the area, and it was while ...
