Humus significantly influences the bulk density of soil and contributes to moisture and nutrient retention. Soil formation begins with the weathering of humus. In agriculture, humus is sometimes also used to describe mature, or natural compost extracted from a forest or other spontaneous source for use to amend soil.
The CAGR Formula. From Investopedia, Compound Annual Growth Rate ( CAGR ) is calculated as: =(Ending Value/Begining Value)^(1/# of years) -1. Restated: =(FV/PV)^(1/n) -1. where FV = Future Value, PV = Present Value, and n = number of periods. Calculate CAGR in Excel.
What most of us want from the Growth formula is a simple number representing the period over period growth rate of a series of numbers. Compund Annual Growth Rate (CAGR) is a typical example. The formula for CAGR is not difficult. For calculating growth from a single start time and a single end time it's sufficient. =((End Value/Start Value)^(1/(Periods - 1)) -1.
