  • Case study - EDRO in soil at petroleum tank farm site

    Environmental engineers needed quick and accurate screening analysis on a tank farm contaminated with a subsurface plume of fuel oil. Sitelab's EDRO test was performed to delineate the vertical extent of contamination. A drill rig was used to collect samples from the surface down to twenty feet at different locations throughout the property. They needed to quantify the size of the NAPL plume in ...

  • Losing Soil

    In 1938, Walter Lowdermilk, a senior official in the Soil Conservation Service of the U.S. Department of Agriculture, traveled abroad to look at lands that had been cultivated for thousands of years, seeking to learn how these older civilizations had coped with soil erosion. He found that some had managed their land well, maintaining its fertility over long stretches of history, and were ...

  • Sustainable Farm Practices for Rice Farming

    Rice is the third-largest crop production, after sugarcane and maize. The main producers of rice are the nations of China, India, Indonesia, Bangladesh, and Vietnam. Rice is a staple crop. More than half the people in the world, about 3.5 billion people, rely on its production. Not only is rice a key source of food but it is also good source of income for many smallholder farmers. The Challenges ...

  • Vermicompost’s Role in Farming

    One of the main goals of every organic farmer is to build long-term soil fertility and tilth by feeding the soil with a variety of natural amendments. The regular addition of compost is one of the best ways to enhance the soil’s organic and humic content, which helps to build a fertile soil structure. This soil structure makes better use of water and nutrients. It is easier to till and, ...

  • Effect of implementing organic farming on chemical and biochemical properties of an irrigated loam soil

    Conventional agriculture can lead to reduced soil organic matter and depletion in soil fertility. For that reason, Food and Agriculture Organization of the United Nations (FAO) recommends organic matter incorporation to soils to increase their agronomic quality. This work studies the effect of the transition to organic farming on chemical and biochemical properties of a loam soil (Xerofluvent), ...

  • Soil and Water Benefits: Composting Reduces Fuel and Labor Costs on Family Farms

     Composting Reduces Fuel and Labor Costs on Family Farms Jeff and Pam Riesgraf — who manage a certified organic dairy and crop operation near Jordan, Minnesota — began composting manure from their dairy herd in 1993. They had two major objectives. First, they wanted to reduce weed seeds naturally present in manure. At the same time, they understood the need to protect water quality by ...

  • Knowledge of Farm Practices – The Key for Successful Farming

    Agriculture plays an important part in the world economy. One-third of the economically active population obtains its livelihood from agriculture. In Asia and Africa, millions of small-scale farmers, fishermen, and indigenous people produce most of the food consumed worldwide, in most cases on very small plots of land. Agriculture is increasingly called upon to address a wide range of critical ...

  • On-farm evaluation of the improved soil nmin–based nitrogen management for summer maize in North China plain

    The improved soil Nmin–based N management is a promising approach to precision N management, which determines the optimum side-dress N rates based on N target values and measured soil nitrate N content in the root soil layer at different growth stages. A total of 148 on-farm N-response experiments, in seven key summer maize (Zea mays L.) production regions of North China Plain (NCP) from 2003 to ...

  • Consequences of conventional versus organic farming on soil carbon: results from a 27-Year field experiment

    Organic farming practices are regarded as being beneficial for the environment by promoting soil quality and sequestering soil organic carbon (SOC). We studied SOC dynamics in the long-term field experiment DOK in Switzerland. The experiment compares three organically fertilized treatments under conventional (CONFYM), bioorganic (BIOORG), and biodynamic (BIODYN) management, and two systems with ...

  • On-farm evaluation of winter wheat yield response to residual soil Nitrate-N in North China plain

    High soil nitrate-N accumulation has been observed in North China Plain (NCP), but it was seldom considered as a N source in N management due to the lack of data on crop response to soil nitrate-N accumulation. A total of 124 on-farm N-response experiments were conducted from 2003 to 2006 in seven key winter wheat (Triticum aestivum L.) production regions of NCP to evaluate wheat yield response ...

  • Is organic farming climate friendly?

    Think organic farming is climate friendly? You might want to think again. A study published recently in the journal Agriculture and Human Values suggests that as organic agriculture emulates conventional industrial agriculture, the environmental benefits may not be the slam-dunk that ...

  • Adding Value To On-Farm Digesters

    ANAEROBIC digestion of dairy manure and food processing residuals in Michigan is not a new undertaking. Over the years, 11 farm digesters were constructed in the state, of which four are still operational, reports Michelle Crook of the Michigan Department of Agriculture in a presentation in the spring of 2007. “Three of the operating digesters are for livestock manure and one is for food ...

  • High Technology that Revolutionized Farming

    How are we going to feed the growing population by 2050? How we are going to double our food supply and how will the farming be sustainable? All the answers involve farm technology. Farm technology creates the ability to grow plants that are disease resistant, to use the equipment that can target individual crops and strengthen the rice that can survive drought and flooding and literally save ...

  • Salinization/sodification of soil and physiological dynamics of sunflower irrigated with saline–sodic water amending by potassium and farm yard manure

    Sunflower (Helianthus annuus L.) plants were grown with saline–sodic water (SSW) by treating with potassium (K @ 100 and 200 mg K2O kg−1 soil) and farm yard manure (FYM @ 5 and 10% of soil, w/w). Irrigation with untreated SSW caused soil salinization/sodification, leading to an increase in electrical conductivity (EC) of 165% and sodium adsorption ratio (SAR) 100% with ...

  • On site at Northdown Orchard Organic Farm

    On Saturday 15th of October we were on site with Mike and the team at Northdown Orchard, an existing customer who was kind enough to show us around the farm and let us snap some great photos at his site in exchange for a morning demonstrating our latest stone burier on his tractor. About Northdown Orchard The organic farm is a family run affair and sits on a site of ...

  • Microorganisms as indicators of soil quality

    If we are to monitor soil quality, we need indicators of trends and changes. In order to choose relevant indicators, we must understand the factors controlling soil quality. Soil quality is dependent upon the physical, chemical and biological soil components. The interaction between these components is complex. The chemical and physical components have been more fully investigated than the ...

  • Ancient Trick for Soil Improvement

    Today, when every farmer is facing a battle of food production for a growing population, crop production has become much more intensive. These farm practices, which usually include monoculture, harm soil nutrient composition and deplete this valuable natural resource. Using the same crop on the same field keeps draining the soil of essential nutrients. Monoculture combined with intensive farm ...

  • It is vital to reinvigorate organic farming research

    Organic farming can deliver food sustainably, but only with compelling science to boost its use, argues Ged Buffee. With increased yields and ecological stability becoming critical concerns for agricultural development, there's ...
