No-till farming ,also known as zero tillage or direct drilling is an agricultural technique for growing crops or pasture without disturbing the soil through tillage.No-till farming decreases the amount of soil erosion. tillage causes in certain soils, especially in sandy and dry soils on sloping terrain
The effects of tillage can include soil compaction loss of organic matters; degradation of soil aggregates; death or disruption of soil microbes and other organisms including mychorrazea, arthopods, and earth worms; and soil erosionwhere top soil is washed or blown away. Tillage is the Agricultural preparation of soil by mechanical agitation
The uses of tillages are In some cases it may reduce labour, fuel, irrigation and machinery costs.No-till can increase yield because of higher water infiltration and storage capacity, and less erosion.it reduces costs like A combination of technique, equipment, pesticides, crop rotation, fertilization, and irrigation have to be used for local conditions.
It used for One of the purposes of tilling is to remove weeds. No-till farming changes weed composition: faster growing weeds may be reduced as increased competitions with eventual growth of perninals, shrubs and trees. No-till occasionally uses cover crops to help control weeds and increase organic residue in the soil
No-till farming reduces nitrous oxide (N2O) emissions by 40-70%, depending on rotation.Nitrous oxide is a potent greenhouse gas, 300 times stronger than CO2, and stays in the atmosphere for 120 years.No-till farming improves aggregates and reduces erosion Soil erosion might be reduced almost to soil production rates.
But it have some draw backs like using morr herbicides and again and again tillage,risks to control weeds,take more time to yields and less crop yield.

This is a well detailed explanation of zero tillage farm. It has the potential to greatly improve food production. However, where I am from we have tried it a number of times and it failed.

Yes, but in some areas this is well known.
I agree with u.it has some Drawbacks
