It seems like all I’ve been doing lately is weeding and mulching. It’s taken longer than I wanted, but slowly but surely my garden beds are enjoying a nice layer of straw to help insulate the soil, form a layer that’s harder for weeds to penetrate, and retain moisture. I usually wait until plants are established before mulching, but I’ve recently learned about year-round mulching, which doesn’t sound like such a bad idea.

What is mulch? It’s basically any material (usually organic matter) that is used to cover exposed soil in the garden, and can be used for beds, containers, and even paths. Exposed soil can dry out quickly and be easily eroded by water and wind, so a covering helps keep it moist and healthy. The type of mulch you choose depends on the needs of the area you’ll be mulching, but I recommend staying away from unnatural materials like black plastic and choosing organic materials like straw, hay, decomposing leaves, rice hulls, or even dead & dried out weeds. Organic material will break down slowly and help add humus to the soil, making it richer and healthier for gardening.

The truth of the matter is that cellulosic ethanol will be made from non-food sources (miscanthus, switchgrass, wood waste, and even garbage) that can be grown on marginal land or is already a waste byproduct of society.

The production of cellulosic ethanol could have huge benefits beyond energy independence:
