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.
CAGR = [(FV / PV) ^ 1/n] - 1. Whereas, FV is future value or the ending value of an investment; PV is the present value or the beginning value of an investment; and n is the number of years. CAGR is used to measure the value of an investment and its growth over a given period of time to estimate the total return on a particular investment. While the annual rate of return gives the amount of return every year, CAGR gives the return over the entire period of the investment.
