soil is a living entity-bio dynamic factor-
One acre of soil contains nearly about of 11 metric tonnes of micro organism and other soil living organism say, bacteria, fungi, actinomycetes, earthworms, soil living insects all put togehther count this weight.
The bacteria act on dead plant and animal waste , decompose it , release nutrients into soil - recycling
The decomposed organic matter as humus improve soil structure as crumby as possible with good aeration and water holding capacity of the soil , essential for plants growth and development..
The bacteria itself when died get integrated into soil systems where by it makes film layer around soil particles , giving amino acids , vitamins and other essential organic components to plant roots
The earth worms grind soil particles mix, churn and overturn it and in the course of soil passing thro' its body the intestinal secretion pass along with soil particle , thus making it rich in amino acids , vitamins , hormones etc..and along with worm castings soil get enriched..to support plants growth and development..
The fungus present in the plants associate itself with the roots of the plants enabling it to absorb and retain moisture and uptake of nutrients from soil colloidal system..
Thus soil micro organism play major role and really makes soil a living entity.
So indiscriminate use of chemical fertilizers and pesticide and weedicide will kill the soil living organism and simply makes dynamic living medium into dead useless inert matter..
So I am not advocating to avoid application of synthetic fertilizers but there is a limit to everything..instead of total dependence on synthetic chemical fertilizers , let us just supplement it with naturally available nutrients medium like cow dung, compost, vermicompost, cow urine etc..
Let the soil bio dynamism continue for ever ...for sustained agricultural production...
