from exec summary: "This project sought to quantify the effect of compost feedstocks (green waste and poultry manure), compost maturity, and soil texture on vegetable crops. All of the field work was conducted in cooperation with commercial vegetable growers in Santa Cruz, Santa Clara, and San Benito Counties. Initially, the intent was to work equally with conventionally and organically farmed crops. However, in the end, the majority of the field trials occurred on conventional farms. Efforts to match similar crops to trials performed on different soil textures (conventional and organic) were largely unsuccessful due to the inevitable complications inherent in on-farm studies."
