Oat straw to reduce weeds

Some have used straw.   I am not sure whether it came from oats or wheat or
what, but I would think the effect would be the same. It works to keep
the soil moist and to build up fertility.  It decays quickly.   We use
newspaper underneath woodchips in our Santa Fe Iris Society public iris
Garden to keep weeds down.  Incidently, they feed the soil and keep it
healthier and they last longer than does oat straw.  Both methods need
to be replaced from time to time.
