  • Combined particle swarm optimization and fuzzy inference system model for estimation of current-induced scour beneath marine pipelines

    In this paper the capability of Particle Swarm Optimization (PSO) is employed to deal with an Adaptive Network based Fuzzy Inference System (ANFIS) model's inherent shortcomings to extract optimum fuzzy if–then rules in noisy areas arising from the application of nondimensional variables to estimate scour depth. In the model, a PSO algorithm is employed to optimize the clustering parameters ...

  • Redrow homes farnborough

    Tree root protection is a task faced by many developers as they seek to provide cost-effective housing whilst preserving the surrounding environment in the face of large scale developments. A perfect example is Redrow Home’s exciting new housing project, Farnborough Central located within 2.5km of the Thames Basin Heaths Special Protection Area (SPA), a site requiring adequate measures for ...

  • Features of impulse sprinkling technology

    The principle of non-stop water supply to plants and soil in accordance with their water intake is progressive. Drip irrigation and impulse sprinkling correspond to this principle. Drip irrigation provides optimal water and nutrient regimes directly to the root system of plants. However, this irrigation is not effective enough under conditions of high temperature (over 25–35 °C) as growth ...

  • Method for irrigation scheduling based on soil moisture data acquisition

    The water requirements of crops are dependent on evapotranspiration (ET), soil chemistry, and the crop’s maximum allowable depletion (MAD). Direct measurements of root zone soil moisture, water application along with published ET values and soil textures, can be used in a soil water balance model that can significantly optimize irrigation efficiency. Over the past five years, advancements in ...

  • Application of artificial neural network to model the energy output of dairy farms in Iran

    An artificial neural network (ANN) model was developed to assess the energy input–output prediction in dairy farms of Iran. Data used were culled from 50 randomly selected farms using face to face questionnaire approach. The energy input–output analysis was carried out for the parameters of ANN model. Based on performance measures, single hidden layers with 16 neurons in the hidden ...

  • Special features of drip-sprinkler irrigation technology

    Irrigation techniques and technology based on principle of regular accumulation of moisture in active layer (surface irrigation, regular sprinkler irrigation) are most common in science and in practice. More progressive is principle of non-stop water supply of plants and soil in conformity to their water consumption. Drip irrigation and impulse sprinkling are based on this principle. The main ...

  • Basics of evapotranspiration

    Evapotranspiration (ET) represents the loss of water from the Earth’s surface from the combination of direct evaporation and plant transpiration. ET is usually expressed as a rate such as inches per day. Knowledge of ET is important for irrigation scheduling but it is also an important factor for other land use applications such as septic tank drain fields, water shed water budgeting, and climate ...

  • Compost Users Forum: The Applied Thoughts Of A Compost Theorist

    WITHIN a 60-mile radius of my office here in central California, there are 1,000 dairies — each having an average of 2,000 cows. They generate over four million tons of manure annually, so we are pretty much in the manure business whether we want to be or not. Somebody has to manage this material and help the farmers utilize it properly, fulfilling its potential monetary value. That’s what we ...

  • Ontario Horticulture Research Priority Report 2016

    Sector Consultation The Ontario Fruit and Vegetable Growers Association partnered with Vineland to host a research strategy workshop in November 2014 with the goal of defining the top five research priorities for each crop group. Grower organizations were invited to nominate two representatives to participate on their behalf and a number of researchers from relevant fields were invited to ...

  • Evaluating Microbiology of Compost

    The fact that not all compost is created equal has both producers and growers looking for ways to successfully evaluate compost quality. Traditional compost analysis has focused on NPK and micronutrient concentrations in an effort to mirror fertilizer analysis. Compost, however, is much more complex than fertilizer and its most significant value to the grower may be far more than its mineral ...

  • How green was my Vertical Farm?

    By 2050, 80% of the earth’s population will live in cities and 3 billion more people will need to be fed. The simple fact is we are running out of available land to grow enough food to feed them. If we can’t grow our cities outward to find more arable land, the only solution is to grow them upwards. This may change the way we design cities forever.The problem is real and immediate. Even by most ...

  • Family farms can be competitive by focusing on conservation and stewardship

    While the U.S. Department of Agriculture (USDA) reports a 40 percent decline in U.S. cropland soil erosion rates from 1982 to 2007, recent trends appear to challenge this progress. Record prices for corn and soybeans have diverted acres out of conservation programs and encouraged intensive production on a wide scale. Tree lines are cleared and wet areas drained, turning 120-acre farms into ...

  • Emissions from Crops - POST Note

    Agriculture contributes 9% of the UK’s greenhouse-gas (GHG) emissions burden and 10-12% globally. Although there is a long-term declining trend from UK agriculture, the sector may account for a larger share of overall emissions in the future as other sectors reduce emissions. This POSTnote focuses on reducing GHG emissions from growing and storing arable and horticultural crops. ...

  • REDD+ progress is possible — just look at Indonesia

    In the global drive to cut greenhouse gas (GHG) emissions, REDD+ transactions have become prominent. REDD+ stands for Reducing Emissions from Deforestation and Degradation plus safeguards, such as transparent governance and respect for indigenous peoples’ rights and knowledge. REDD+ transactions agree ways for governments, communities and ...

  • Agroecology can help fix our broken food system. Here’s how.

    The various incarnations of the sustainable food movement need a science with which to approach a system as complex as food and farming. This story was co-published with Food Tank, a nonprofit organization focused on building a global community for safe, healthy, nourished eaters. Thumb through U.S. newspapers any day in early 2015, and you could find stories on ...

  • Compost science journal of advocacy and foresight

    SEVERAL months ago, I started on a journey through the pages of Compost Science, beginning with the Spring, 1960 inaugural issue. I was confident that I could whip through the articles and news items in the several hundred issues of the magazine between 1960 and 2009, and be prepared to write this article for BioCycle’s 50th Anniversary Commemorative Edition. Granted, there were interruptions, ...
