Dr. Shannon Cappellazzi is teach grad student Chris Lessey how to use the Saturo.
Cover crop seed has arrived. When you don’t have a loading dock or pallet jack, improvisation is necessary.
Kevin discussing seeding plan
CTUIR wheat field that will be harvested and planted to cover crop.
Dirty work, but someone has to do it. Feeling thoroughly emerged in my work after a day in the field.
Chris sampling fields
The "brains and lungs" of the operation. The computer inside the case lets you set the program and regulates with water and air pressure to calculate the rate at which water can move through a saturated soil.
Dawn at CTUIR. Wildhorse Casino sign in the background. Saturo (TM) saturated hydraulic conductivity equipment in the foreground.
Saturo(TM) measurements from dusk to dawn. You can set up the machine and walk away.
See those little soil islands floating in the water. Those soils are highly hydrophobic. Ie water fearing. It is also referred to as water repellent.
Silty soil can be hydrophobic and even with a fresh vertical tillage pass, one inch of water can sit on top of the soil for over 14 minutes.
Water infiltration is highly variable
Samples go directly into a cooler
Planting cover crop seed into a dusty silt loam
Wheat stubble - ready to be planted
Biocrust in saturated soil
Biological crusting in a very wet area of a saline soil
Wetland protected area. Cat tails are a great nutritional food
An area with a very low water table that CTUIR is just starting to manage
Kevin is 6.3. This Kochia weed is taller.
Kevin showing us the size of the massive Kochia weeds in a new field he is going to start working. We discussed what cover crops to use here
Less well aggregated section of Neagle Flats. Higher pH, lower OM
Farm Scale Plot Work preparation
First set of Saturo Measurements. Automated equipment from the Meter group that measures the rate of water movement through saturated soil using a dual pressure head calculation.

Each step creates a cloud of fine powder. The soil is very high in silt which has about the same texture as flour.
Some areas of the field, each step creates a plume of silt dust.
Even just touching the surface stirs up dust.
I like this video. Shows the light and fluffy surface and how easy it is to get a probe one foot in.
