i) Reduced tillage
Reduced tillage leaves between 15 and 30 per cent residue cover on the soil, that is,
560 to 1,100kg/ha of small grain residue during the critical erosion period. It involves
the use of a chisel plow, field cultivators, or other implements.
ii) Intensive tillage
Intensive tillage leaves less than 15 per cent crop residue cover or less than 560kg/ha
of small grain residue. Intensive tillage often involves multiple operations with
implements such as a mound board, disk and/or chisel plow. Then a finisher with a
harrow, rolling basket and cutter can be used to prepare the seed bed. There are many
variations.
iii) Conservation tillage
Conservation tillage leaves at least 30 per cent of crop residue on the soil surface, or at
least 1,100 kg/ha of small grain residue during the critical soil erosion period. This slows
water movement, which in turn conserves the soil.With the changing climate,
conservation tillage is the most suitable since it helps to preserve the soil moisture for
longer periods. This means that the moisture will be available during the flowering
stage, where crops require plenty of water.
