  • Interpretation of laboratory analysis of biosolids samples 

    Brown, James R.; Sievers, Dennis; Magai, Robert (University of Missouri. Extension Division, 1995)
    "Biosolids material is useful for land application. It contains organic matter and plant nutrients, such as nitrogen (N) and phosphorus (P). But, biosolids material from municipal secondary waste treatment plants does not ...
  • Activity and movement of plant nutrients and other trace substances 

    Hoette, Gary D.; Brown, James R.; Arnold, Ken (University of Missouri. Extension Division, 1995)
    "Biosolids is the term for an organic fertilizer or soil amendment produced by the treatment of domestic wastewater. Domestic wastewater treatment and disposal are evident in the archaeological digs, but the practice of ...
  • Benefits and risks of biosolids

  • Nitrogen in the environment : nitrogen replacement value of legumes 

    Killpack, Scott C.; Buchholz, Daryl (University of Missouri. Extension Division, 1993)
    "Nitrogen is essential for all plant life. Regarding agricultural crops, a sound nitrogen management program is important for achieving high yields. For many crops, application nitrogen fertilizer is both a practical and ...
  • Nitrogen in the environment : essential plant nutrients 

    Killpack, Scott C.; Buchholz, Daryl (University of Missouri. Extension Division, 1993)
    "Carbon, oxygen and hydrogen are among the most basic elements necessary for plant growth. Plants obtain these elements from water and carbon dioxide in the air and soil. Plants also require additional "mineral elements" ...
  • Nitrogen in the environment : leaching 

    Killpack, Scott C.; Buchholz, Daryl (University of Missouri. Extension Division, 1993)
    "When soil becomes excessively wet through rainfall, the soil will reach a point where it cannot hold any more water. This happens because the air spaces between soil particles become filled with water. As these air spaces ...
  • Nitrogen in the environment : nitrogen fixation 

    Killpack, Scott C.; Buchholz, Daryl (University of Missouri. Extension Division, 1993)
    "Nitrogen can be found in many forms in our environment. Nitrogen is also very important for plants to live. The earth's atmosphere is made up of 78 percent nitrogen in the forms of a colorless, odorless, nontoxic gas. The ...
  • Nitrogen in the environment : mineralization -- immobilization 

    Killpack, Scott C.; Buchholz, Daryl (University of Missouri. Extension Division, 1993)
    "Nitrogen exists in many forms in the soil and is essential for plant growth and development. Most of the nitrogen found in the soil is in numerous different organic forms. However, plants are unable to use organic forms ...
  • Nitrogen in the plant 

    Buchholz, Daryl (University of Missouri. Extension Division, 1993)
    "Nitrogen in the plant is a very important subject. There is more nitrogen in plants than any other element, with the exception of carbon, hydrogen and oxygen. Nitrogen plays an important part in many essential functions ...
  • Nitrogen in the environment : nitrate poisoning 

    Killpack, Scott C.; Buchholz, Daryl (University of Missouri. Extension Division, 1993)
    "Nitrate (NO-) is a naturally occuring form of nitrogen found in soils. Nitrates result from the biological decay of plants, animals and organic matter. Nitrates in the soil can also result from nitrogen fertilizers and ...
  • Nitrogen in the environment : ammonia volatilization 

    Killpack, Scott C.; Buchholz, Daryl (University of Missouri. Extension Division, 1993)
    "Although nitrogen is quite stable in the atmosphere, the form of nitrogen in the soil can change very easily. Some forms of nitrogen can be changed to ammonia gas (NH3). Ammonia gas can be lost from the soil and return ...
  • Nitrogen in the environment : how nitrogen enters groundwater 

    Killpack, Scott C.; Buchholz, Daryl (University of Missouri. Extension Division, 1993)
    "Nitrogen can be found in many different organic and inorganic forms in our environment. The air we breathe is composed of 78 percent nitrogen. Nitrogen can also be found in many varied forms in the soil. Plants need ...
  • Nitrogen in the environment : denitrification 

    Killpack, Scott C.; Buchholz, Daryl (University of Missouri. Extension Division, 1993)
    "Soil microorganisms need oxygen for fuel. When the soil is very wet, water fills in the space between soil particles. This leaves very little room for oxygen. Some soil microorganisms can get the oxygen they need form the ...
  • Nitrogen in the environment : nitrification 

    Killpack, Scott C.; Buchholz, Daryl (University of Missouri. Extension Division, 1993)
    "Many organisms live in the soil. Some of these are able to change ammonium nitrogen (NH4+) to nitrate nitrogen (NO3-). This process is called nitrification. Nitrification has two steps -- both are carried out by bacteria ...
  • Nitrogen in the environment : nitrogen's most common forms 

    Killpack, Scott C.; Buchholz, Daryl (University of Missouri. Extension Division, 1993)
    "Nitrogen is important for all plants to live, and it comes in many forms. Although the atmosphere is mostly made up of nitrogen, it is in the form of a gas known as dinitrogen N2. Plants cannot use this form. Dinitrogen, ...
  • Nitrogen in the environment : what is nitrogen? 

    Killpack, Scott C.; Buchholz, Daryl (University of Missouri. Extension Division, 1993)
    "Nitrogen is extremely important to living material. Plants, animals and humans could not live without it. The major source of nitrogen is the atmosphere. It exists as a colorless, nontoxic gas and makes up about 78 percent ...
  • Calibrating manure spreaders
