NO TILL FARMING No-till farming (also called zero tillage or direct drilling) is a way of growing crops or pasture from year to year without disturbing the soil through tillage. No-till is an agricultural technique which increases the amount of water that infiltrates into the soil and increases organic matter retention and cycling of nutrients in the soil. In many agricultural regions it can reduce or eliminate soil erosion. It increases the amount and variety of life in and on the soil, including disease-causing organisms and disease suppression organisms.

No-till farming (also called zero tillage or direct drilling) is a way of growing crops or pasture
from year to year without disturbing the soil through tillage. No-till is an agricultural technique
which increases the amount of water that infiltrates into the soil and increases organic matter
retention and cycling of nutrients in the soil. In many agricultural regions it can reduce or
eliminate soil erosion. It increases the amount and variety of life in and on the soil, including
disease-causing organisms and disease suppression organisms. The most powerful benefit of no-
tillage is improvement in soil biological fertility, making soils more resilient. Farm operations
are made much more efficient, particularly improved time of sowing and better trafficability of
farm operations.
