A few weekend ago I decided the Fava beans had reached the end so after pulling off any remaining beans I chopped them all down. Half the waste was left in place and the other half went into the composter.
While doing some final clean up from the landscaping I discovered the dirt at the bottom of the yard (next to the old retaining wall) was loaded with silt. Basically all of the fine particles had washed from the top of the yard to the bottom creating clay like soil. A bunch of this diet was moved to the top planter and tilled in with the compost and fava waste.
It is interesting to note the plant difference in the various soils as all of the lettuce and brusselsprouts were planted at the same time. The last most bed is Miracle grow organic planting bed soil, the rift planter is a 50:50 mix of compost and my soil, and the top two brussel sprouts are in the straight garden soil.
As you can see the miracle grow soil is doing the best and straight soil is doing the worst.
