  • Monitoring of soil fertility

    Background In agriculture and forestry soil fertility is a decisive factor for the economic use of fields and forests. Various factors, considered as a whole are the indicators which characterize the soil fertility. Important parameters are e.g.: Intensity of precipitation, air temperature, air humidity, soil humidity, suction power and soil temperature in various depths. ...

  • Soil water content and soil disaggregation by disking affects PM10 emissions

    Row crop agriculture in California's San Joaquin Valley is a major contributor of particulate matter <10 µm in aerodynamic diameter (PM10). The California Air Resources Board uses fixed PM10 emission values for various tillage operations to monitor and design attainment strategies. However, fixed emission values do not reflect emissions produced by a single implement operating under different ...

  • 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 ...

  • Monitoring Water Resources Beyond Irrigation

    Over the past year, California’s governor has taken unprecedented action, requiring Californians to drastically cut potable urban water use. While the restrictions may seem harsh to some, it actually provides an opportunity for building managers and community association boards to implement an effective long-term water conservation program. And the result can be significant dollar savings. ...

  • Monitoring Moisture In Composting Systems

    Monitoring Moisture In Composting Systems IF YOU SQUEEZE a handful of material and water drips or trickles out, it is the right moisture content for composting.” This bit of hands-on wisdom comes from the proverbial squeeze-test for evaluating moisture in composting piles. It has been uttered by Master Gardeners and other composting educators for many years as a tool for determining, and ...

  • Soil fertilization with wastewater biosolids – monitoring changes in the ‘soil–fertilizer–plant’ system and phosphorus recovery options

    The aim of this study is to establish changes that may occur after a prolonged application of wastewater sludge treated to biosolids, in the ‘soil–fertilizer–plant’ system. Thirteen experimental plots with different soil types planted with experimental crops were investigated in order to evaluate the suitability of these biosolids as soil conditioners and fertilizers. The biosolids were ...

  • Online monitoring of algae concentration with ALGcontrol - Case Study

    Online monitoring of algae concentration with ALGcontrol The presence of algae in surface waters is a potential threat to the quality and ecology of the water system. The control and monitoring of the algae concentrations are therefore of high importance. Due to green algae problems in the water reservoir of a drinking water treatment plant, the ALGcontrol was installed to continuously monitor ...

  • Flow monitoring for golf course irrigation case study

    “We are all talking about the price of oil, but it's water we'll be fighting for in the future” Summerheights Golf Links in Cornwall, Ontario draws irrigation water from the South Raisin River. Flow rates in the river can become very low during dry periods so water extraction is regulated and monitored closely. Under a water extraction permit issued by the Ministry of The ...

  • Forest Focus Monitoring Database - Validation Methodology

    Forest Focus (Regulation (EC) No 2152/20031) is a Community scheme for harmonised, broad-based, comprehensive and long-term monitoring of European forest ecosystems. It concentrates in particular on protecting forests against air pollution and fire. To supplement the monitoring system, Forest Focus stipulates the development of new instruments relating to soil monitoring, carbon sequestration, ...


  • On-line monitoring of algae concentration with ALGco - Case Study

    The presence of algae in surface waters is a potential threat to the quality and ecology of the water system. The control and monitoring of the algae concentrations are therefore of high importance. The ALGcontrol offers on-line monitoring of different kind of algae through fluometric a (fluorescence) technique. Fluorescence is the property of some atoms and molecules to absorb light at a ...

  • 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 ...

  • Performance of a new capacitance soil moisture probe in a sandy soil

    Rapid population growth and increasing urban demand reduce the availability of water for agriculture in Florida. The water-holding capacity of sandy soils in the Central Florida Ridge area is very poor ( ...

  • No-till corn after Bromegrass: Effect on soil carbon and soil aggregates

    Grasslands in the Conservation Reserve Program (CRP) in the USA may be converted to grain crops for bioenergy. The effect of no-till conversion of a smooth bromegrass (Bromus inermis Leyss) grassland to no-till corn (Zea mays L.) production on soil organic carbon (SOC) in the western Corn Belt was monitored for over 6 yr. A different 13C/12C isotope signature is imparted to SOC by C4 plants ...

  • Monitoring Ozone (in the air) in Hatchery & Fish Farm Ozone Injection Systems

    Hatcheries, fish farms and such in the aquaculture industry require clean water to maintain a high survival rate while rearing aquatic animals. Contaminated water increases the risk of infection which in turn can compromise production. A common way to disinfect water is by generating ozone on-site with an ozone generator, which is commonly inside an ozone generator room. For human safety, ...

  • Use of online nutrient monitoring for automatic aeration and nitrate recycle pump control

    The Northside Wastewater Treatment Plant (WWTP) in Kinston, NC was expanded and upgraded in 2006 for biological nutrient removal (BNR) to meet limits of 3 mg/L total nitrogen (TN) and 1 mg/L total phosphorus (TP). In addition to the traditional approach of controlling the blowers based on dissolved oxygen (DO) readings, the City decided to implement an aeration basin blower control system using ...

  • Harvesting Corn Stover and Soil Quality

    Corn stover, left in fields after corn grain harvest, has been identified as a potential feedstock to help supply biofuel needed to offset a portion of the 14 million barrels of oils consumed daily by the U.S. transportation sector. It was projected to supply 256 million tons of the 1.4 billion tons of biomass (232 million Mg out of 1.3 billion Mg) estimated to be available each year. Corn stover ...

  • Effects of wastewater irrigation on soil properties and turfgrass growth

    Reuse of treated wastewater for turf irrigation is often viewed as one way to maximize existing urban water resources. The aim of this study is to evaluate the applicability of treated wastewater for turfgrass and assess the effects of continuous use of treated water on the soil and crop. Two turfgrass plots irrigated with drinking water and treated wastewater were monitored over a two-year ...

  • Ordinances To Amend Soils Boost Compost Demand

    Municipalities everywhere are realizing that some of the environmental issues they are grappling with locally may be mitigated by healthier soils. In the late 1990s, when Puget Sound Chinook salmon was listed as threatened, Washington State officials scrambled to find ways to improve water quality in the Puget Sound and protect spawning streams. They identified a number of methods to reduce ...

  • Planting trees and managing soils to sequester carbon

    As of 2007, the shrinking forests in the tropical regions were releasing 2.2 billion tons of carbon per year. Meanwhile, expanding forests in the temperate regions were absorbing 0.7 billion tons of carbon annually. On balance, a net of some 1.5 billion tons of carbon were being released into the atmosphere each year, contributing to global warming. The tropical deforestation in Asia is driven ...
