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 RATE formula is calculated by iteration and does not always converge on the correct CAGR value when the inputs take unusually large or very small values. For example, in Excel 2007, RATE returns a #NUM error when asked to calculate the CAGR over 10 periods with P = 10 and A >707 (the correct CAGR is >53.08%).
