  • Nitrogen Basics The Nitrogen Cycle

    Leaching is a pathway of N loss of a high concern to water quality. Soil particles do not retain nitrate very well because both are negatively charged. As a result, nitrate easily moves with water in the soil. The rate of leaching depends on soil drainage, rainfall, amount of nitrate present in the soil, and crop uptake.

    The nitrogen cycle dictates the form and movement of nitrogen in the soil and in plants. 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.

    As water moves down through the soil, nitrogen can be carried with it. This is called leaching (Figure 1). Figure 1 Heavy rainfall can cause nitrates (NO 3 ) to move down through the soil, a process called leaching . Forms of nitrogen that leach. Nitrate (NO 3 ) is primarily the form of nitrogen that is leached. Nitrates may originate from manures, the decay of plants and other organic materials or from fertilizers.
