Although oxygen is excluded from the centre of this "wet" compost pile, worms work from the outside in and introduce air as necessary into the pile to meet their nutritional requirements. This food resource buffer ensures primary treatment vermifilters have a level of resilience and reliability, provided space is provided for a pile to build up.
Worms require gaseous oxygen. [51] Oxygen can be provided by airholes in the bin, occasional stirring of bin contents, and removal of some bin contents if they become too deep or too wet. If decomposition becomes anaerobic from excess wet feedstock added to the bin, or the layers of food waste have become too deep, the bin will begin to smell ...
Microaerophiles need oxygen because they cannot ferment or respire anaerobically. However, they are poisoned by high concentrations of oxygen. They gather in the upper part of the test tube but not the very top. Aerotolerant organisms do not require oxygen as they metabolize energy anaerobically.
It doesn't have to be more than a foot deep, Grossman said, because red wiggler worms are top feeders. If you're using a plastic bin, make sure it's not clear, because the worms prefer a dark ...
Both of these viruses are also “highly resilient,” which means they’re tough to kill. Luckily, there's an easy way to wash any of your fruits and veggies. Find out the simple hack below.
The easy-to-grow plants aren’t particular about soil type and don’t need annual fertilization, but they cannot tolerate soggy soils. Harvest tubers in autumn, preferably after a couple of ...
Low-acid foods, such as vegetables and meats, require pressure canning. Food preserved by canning or bottling is at immediate risk of spoilage once the can or bottle has been opened. Lack of quality control in the canning process may allow ingress of water or micro-organisms.
Cabbage doesn’t pack quite the same punch in terms of nutrition as kale or collard greens, but it’s still a winter staple. It works well in slaws, stir-fries, or even roasted sheet-pan meals ...
