I planted a strip of triticale along the berms last fall in an attempt to  improve soil structure.  Triticale is a cross between the wheat and rye and has a very vigorous root system that will penetrate deeply and help to add organic matter and floculate the soil.  I am having issues in this orchard because the soil is very fine in areas and lacks sufficient drainage to move salts below the roots of the Almond trees.

I am trying this strategy out this year and did not want to plant the entire lane until I see how it works with strips.  The jury is still out but it looks pretty good so far.
