In areas where people walk and cars and machines drive, the soil will be compressed. Roots can not grow in compressed soil for many reasons. Compacting soil on existing roots will make the roots die. In case of rainwater stagnation several unfavorable processes will occur in increasing quantity and speed.
In addition aeration of the soil stagnates and results in a lack of oxygen. If the oxygen level descends below 16% root growth stalls and roots will eventually die if oxygen levels drop further.
To decompress soil both air and water is needed. Minerals, mycorrhiza and polymers can be added to the water.
Biolift1260 is a compact all in one machine with an engine, pump, compressor and pressure tank.
This is the most efficient way to improve the soil.
