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.
The mean is the mathematical average of two or more numbers. The formula for CAGR calculates the average annual growth of an investment. For example, suppose you invested $10,000 in stocks in 2012, and the value grew to 14,000 in 2013, to $15,000 in 2014, and to $19,500 in 2015.
