Additional Tasks

Water table depths ( decimalinchesfeet from top of well casing)

Note: Outside wells require regular screwdriver to open cap

4.22

Off-North

3.40

Vegetation height outside of enclosure – 20 samples (inches)

If Swapping Li-7500 Analyzer

Remove SN#

Install SN#

Other Notes:

-Ran Licor experiments – Aci and APAR curves outside enclosure

-More water on field – both in closest canal to north of enclosure and in area nearer levee

Remember next time to:

Take well casing height

Install soil tube sensors for Delta T, TDR
