Soil Solarization Program Instructions
For using transparent anti-condensation plastic film to manage
selected soilborne plant pathogens and weed seeds; developed for
nursery beds.
Instructions - how to use the "SOLARIZE" soil solarization
program. See
also model
documentation (pdf)
- Select options to fit your situation.
- Locations currently limited to Western OR, WA, CA stations
with solar radiation data (RAWS, AGRIMET, AGWEATHERNET, and
CIMIS networks). NOTE: WSU AGWEATHERNET data is not available
before 2015.
- For Start Date, default is today.
- For End Date, default is 50 days from today.
- When available, observed weather data from the "start
year" are used. When that is not available, data from a 7-day
forecast are used, followed by data from the prior year you
select. In effect, the program uses the prior year's data as
if it were a forecast for the start year.
- For nursery beds with crushed rock on the surface of the
soil, select the depth. Otherwise leave this at 0
inches.
- The temperature at 20 inches (50cm) is used as an input to
the calculations. The default is 80 Degrees Fahrenheit.
- Model output can be presented in several different forms.
The forms of interest to most users are: highcharts
graphs, tables, and english sentences.
- Mortality models exist for several disease and weed
species, and more may be added. Select as many as you
wish.
- Click "RUN SOLARIZE MODEL" button to and wait a few seconds
for results.
- If you chose highcharts graphs, you can show data
values and zoom in with your mouse.
- Some weed seed models have red horizontal lines on them. For
these species, the line labeled emergence limit marks the
greatest depth from which a seed of that species can germinate and
emerge. Adequate solarization to that depth means that the weed
should not emerge until the soil is tilled. The line marked
seed bank limit is a typical value for tillage depth;
your actual tillage depth may be different. Adequate solarization
to your tillage depth means that the weeds should not appear, even
after the soil is tilled.
- To re-run model just change settings and click RUNS SOLARIZE
MODEL.
- If graphs are blank, try a different weather station.
This project funded by USDA-NIFA Western IPM Center Initialization
& Signature Program grants, and by the statewide Integrated
Pest Management Program of IPPC at Oregon State University.
This program on-line since Jun. 16, 2016. This is version
2.0alpha5, which is under active development as of Mar. 11, 2019
