Earthworms also stimulate microbial activity by increasing soil aeration and moisture, and transporting litter into the ground where it becomes available to other soil fauna.
12.
Crops, especially alfalfa plants, are cultivated in vast areas of the farm using soil aeration by earthworms to produce natural concentrates for the production of food supplement tablets.
13.
Clonal rootstocks are selected for tolerance of specific soil and disease conditions, such as poor soil aeration or resistance to the soil-borne disease ( root rot ) caused by " Phytophthora ".
14.
Examples of such conditions include waterlogging or soil compaction resulting in poor soil aeration, excessively high or low soil temperatures, and above-ground conditions that result in low translocation of sugars to plant roots.
15.
By so doing, water penetrates more easily into the soil, soil aeration is increased, and the activity of soil biota is enhanced; the final result is a seed bed that is suitable for planting.
16.
The outcomes of his research on gas transport were to conclude that the exchange of gases in soil aeration takes place by diffusion and is " sensibly independent of the variations of the outside barometric pressure ".
17.
Soil aeration is the process of using mechanized or manual equipment to either puncture the soil with spikes ( spike aeration ) or remove approximately 1 " x 2 " cores of soil from the ground ( core aeration ).
18.
The benefits were increased plant growth, increased phosphorus uptake and soil nitrogen content, higher soil organic matter content, and soil aggregation, attributed to higher legume nodulation in the presence of AMF, better water infiltration, and soil aeration due to soil aggregation.
19.
As I often say, planting garden annuals and herbaceous perennials is not particularly difficult and involves only digging the soil to a reasonable depth, bringing in organic material to upgrade its organic status and moisture retention, as well as coarse sand for all-important soil aeration and drainage, to ensure healthy plant growth.
