[permaculture] gabions

Here on the Texas Gulf Coast, I have had success filling erosion ravines
that drain to a bayou with branches, leaves and pine needles. During heavy
rains the runoff water no longer rushes through the ravines and more organic
matter is collected by the existing material. This helps to increase water
infiltration in the future by mulching the soil and making the ravine
channel less steep and deep. What you are describing is similar to trenches
placed on cultivated land, esp. corn fields, where farmers would fill the
trench with ground corn stalks and trench compost for the season. The
following year the trench would be dug along another row and the process
repeated. Over a period of years most of the field would have been treated
with a composted mulch that increased water infiltration and soil fertility.
This system was popular after the Dust Bowl, early 1900's, in the central
United States. If there is plenty of brush left over from land clearing in
the area all you need is a way to effectively fill the trenches. Grinding
the material is not necessary and it will last longer as a mulch if it is
not ground up. This will take a lot of labor and/or machine work. Best of
luck!

greetings, the ruts that we are working with are about 3 feet deep and 2
feet
wide. I'd sure like to talk with someone with expereince before starting or
at
least find some literature on the subject. The ruts don't hold water for
long as
they are and then only when it rains but they do enable the water to flow
right
off the property.
