Improving Soil Drainage
... organisms such as bacteria and fungi, earthworms, insects, and the occasional small animal. Drainage In between the small solid particles are air, or "pore" spaces At favorable moisture levels, half of the total pore space ... when the soil is saturated with water, there may be little or no air in the pore space. If drainage is poor, this condition will continue, depriving the plant roots in the soil ...

... , and root initiation is delayed. If fine, rather than fibrous peat is used, the air-filled pore space often is below 20%. This results in less rooting and more disease caused by stress pathogens. ... aeration and drainage properties as compared to peat-sand container media. The percent of air-filled pore space in azalea pots (4" medium depth) after saturation and drainage must be greater than 20%. ...

... (1/32 to 1/16 inch in diameter), densely compact masses of thick walled cells. Sclerotia are first white, changing to buff, brown and black with age. They are irregular in shape, generally taking the shape of the pore space where they are formed. Sclerotia enable the fungus to persist in fallow soil or soil planted to resistant crops for several years. ...

OREP - Increasing Nitrogen Use Efficiency In Corn Production Systems: Quantifying Effects Of Quality Of Soil Structure And Water Regimes
... soils, if the results apply to field conditions. Further research is necessary to investigate this possibility. Nitrogen mineralization is normally quadratically related to water content or water-filled pore space (WFPS), declining at low water contents due to low water potential and at high water contents due to inadequate aeration and subsequent denitrification. Consequently, there was not a ...

... this, drill holes on the ground just beyond the drip line to let lots of oxygen into the soil. Compaction reduces the soil pore space as much as 50%. Ideally the porosity should be 80%. And lastly - only young trees can benefit from fertilization. An older tree could be fertilized with ammonium nitrate, but it is not really necessary. The hardiest known ...
