Illegal drug users get fired more frequently (4.6 percent were terminated within the past year compared to 1.4 percent of non-users). Drug users also switch jobs more frequently; 32.1 percent worked for three or more employers in the past year, compared to 17.9 percent of non-drug-using workers.
This can mean a good supply of mulch alternatives. Grass clippings can only be used as mulch if the clippings are added to other types of mulching ingredients. The reason for this is that grass clippings do not have a free circulation of oxygen and actually can build up methane gas in larger volumes.
When placed on the soil surface as mulch, wood/bark chips do not tie-up soil nitrogen. Do not use fine sawdust for mulch, because it could create carbon to nitrogen imbalance. Figure 3. Wood or bark chips make excellent mulch between raised-bed boxes. Do NOT put wood or bark chips on the growing bed.
