Lab 3.1: How to use the biomass equation

Several people have had problems using the formula for calculating the biomass.
When calculating the biomass of trees, many students have trouble with the logs (ha, ha!)

1.      Here is the equation: log₁₀M = -1.25 + 2.66 log₁₀D

2.      Different calculators require different sequences of keys to do functions. I am going to use the Windows Scientific Calculator, found on any Windows PC. (Go to Start - Programs - Accessories - Calculator. When the Calculator opens, press View - Scientific.)

3.      “log₁₀” means base-10 logarithms, and is designated by “log” on most calculators (the “10” subscript distinguishes it from natural logarithms, used in calculus and commonly designated “ln” on most calculators).

4.      The inverse of the “log” function is 10^x. On some calculators, you use the “10^x” key. On other calculators, you press “inv-log.” (On the Windows calculator, it’s “inv-log.”)

5.      Whenever you do an equation like this on a calculator, you need to do the log function first, then do the multiplication, then do the addition or subtraction.

Here is the sample equation solved, step - by - step:

(a)        Enter “22” (the tree diameter) and press “log.” You get: 1.34242
(b)        Press “*” then “2.66” then “=” and you get: 3.57084
(c)        Press “-” then “1.25” then “=” and you get: 2.32084
(d)        Check the “inv” checkbox then press “log” and you get: 209
