Properties influenced by organic matter include: soil structure; moisture holding capacity; diversity and activity of soil organisms, both those that are beneficial and harmful to crop production; and nutrient availability.
How Do Oxygen Concentrators Work? How Do Oxygen Concentrators Work? An oxygen concentrator, or an O2 concentrator, sometimes referred to as an oxygen machine or oxygen generator, takes in the ambient air that we breathe and removes or scrubs out the nitrogen, leaving the other gases found in the air, most of which is highly concentrated oxygen.
A portable oxygen concentrator works by compressing air from the environment and then passing it through a sieve bed to remove the nitrogen. The concentrator has two sieve beds containing Zeolite, a cubic crystal that collects the nitrogen when the air is under pressure and releases it with the reduction of pressure.
