Nitrogen in the Environment: Leaching MU Extension

WebNitrate leaching occurs when soil nitrogen, in nitrate form, is dissolved and passes through the soil or when the soil becomes so saturated with water there is overland flow direct to waterways. Nitrate concentrations are highest in the watercourses with the first drainage after the autumn break. WebThe soil is formed by mixing dead organic material with weathered bedrock. Soils in the rainforest are mainly thin and poor. Nutrient levels in the soil are low due to the leaching (washing away of nutrients) by the heavy equatorial rain.
