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.
This Excel spreadsheet uses the formulas above to calculate CAGR. The spreadsheet also rearranges the formula so you can calculate the final amount (given the initial amount, CAGR, and number of years) and the number of years (given the initial and final amount, and CAGR).
