Q3.24. Nutrient retention is an important concept that is often used to help understand and mitigate human-caused changes to nutrient cycling in ecosystems. How would a scientist describe nutrient retention? Use the dropdowns below to complete your answer. Nutrient retention is a measure of how effectively a system limits Submit ◆. When nutrients are retained by a system, they Reset Use the following information for the last question. Farmers often rely on riparian forests- strips of forest vegetation immediately adjacent to streams-to reduce the export of nutrients via streams. The nitrogen budget to the right represents a system containing both corn fields and riparian forest. Researchers want to know if the forest helps retain nutrients from anthropogenic inputs (deposition and fertilizer). 1 Corn/Forest Ecosystem Nitrogen Budget Deposition 10 Fertilizer 135 Denitrification 5 Corn Harvest 50 Stream Export 15 Nitrogen Fluxes (kg ha-¹ y -¹) Q3.25. How much of the observed nitrogen fluxes does the corn/forest ecosystem retain, in kg ha-¹ y ¹? (Hint: Remember that retention rate is NOT the same as storage rate! Click this link to remind yourself how retention is calculated.)
