    What Is the Meaning of Leaching? Garden Guides

    The leaching of nitrogen is of particular concern. Nitrogen, an important plant nutrient, occurs naturally in soil as a result of decomposing plant and animal matter and as a result of soil amendments such as animal manure and nitrogen fertilizers.

    How to estimate nitrogen loss from leaching Morning Ag Clips

    Sep 25, 20170183;32;Given adequate time and temperature, nitrogen in the soil will convert to the nitrate form, which is susceptible to loss in two pathways denitrification, which happens in saturated soils that lack oxygen, and leaching, which happens when water moves through the soil, taking nitrate with it.

    Nitrate Leaching Foundation for Arable Research

    Nitrate Leaching. Nitrate leaching is a naturally occurring process, it occurs when nitrate leaves the soil in drainage water. Nitrate is soluble and mobile. It is no problem when it is within the root zone, but once it gets into the ground water and other fresh water bodies it is an environmental pollutant.

    Nitrogen in the NH4+ N form that isnt taken up by plants is subject to other changes in the soil system. Nitrification is the conversion of NH4+ N to NO3 N. Nitrification is a biological process. It rapidly proceeds in warm, moist, well aerated soils, and slows at soil temperatures below 50 degrees Fahrenheit.
