Lifetime: Lifetime refers to 1. the time during which an organism is alive, and 2. the approximate time it would take for the part of an atmospheric pollutant concentration created by humans to return to its natural level assuming emissions cease. Average lifetimes range from about a week for products such as sulphate aerosols to more than a century for CFCs and carbon dioxide. Also called atmospheric lifetime. Understanding the lifetime of agricultural products and pollutants can help farmers make sustainable decisions.

Leaf Joint: A leaf joint is a point on the stem of a plant where a new shoot may grow. Understanding plant growth points can aid in effective pruning and plant management.
