No-till cropping systems principles: minimal mechanical soil disturbance, permanent organic cover, and diversified crops.

Attractive, profitable, environmentally friendly and sustainable cropping systems have been developed and widely disseminated, based on direct seeding under permanent cover (DMC). 

In these systems, the soil is never tilled and a living or dead cover is permanently maintained. Straw is provided by crop residues, intercrops or catch crops used as ""biological pumps"". These plants have strong, deep root systems and can recycle nutrients from deep horizons to the surface, where they can be used by the main crops. 

They also produce a large biomass quickly and can thrive under difficult conditions such as during dry seasons, on compacted soils, and under heavy weed pressure.
