Stabilized the stones and added more organic matter, soil and small stones behind the big stones. Photo as of mid-March 2015,
Another before-after photos. Below, as of August 2014, six layers of stones in this portion, the main "blocking force" against flash flood in this part of the farm.
After, mid-March 2015, seven layers of stones plus thicker deposit of soil and smaller stones behind them. In the photo is Doy, I hired him for one day extra work.
Cleaning up litter falls that will soon be washed out by flash flood. Before...
...After, Doy patiently raked and gathered these many dried leaves and branches up, behind those stones. There, they will decompose soon and become new rich topsoil that new roots of the trees will "consume".
Photos below taken last April 04, 2015. More dried leaves and branches were added at the back of the big stones.
Then partially covered by soil, taken at the base. The new top soil were organic matter that were trapped by this structure, has decayed. Imagine the amount of top soil that has been preserved, and flash flood that has been temporarily impounded, for a few hours.
How thick or how high is the new soil that has been trapped at the base? Here is one measurement, about 6-8 inches high, or about 3/4 of the shovel base, at around 1.5 meters distance from the big stones.
How it looked before the new topsoil was formed -- hard soil with lots of small stones on the surface.
The big stones on the front. This will change when I go back there next few weeks. We will build a 2nd column of stones behind them.
