The term Conservation
Tillage applies to many different types of tillage and planting
equipment, as well as to the way in which they are used. One of the key
goals of conservation tillage is to leave residues of previous crops on
or near the surface of the soil. These residues cushion the erosive
impact of raindrops on the soil surface, slow surface water flow,
facilitate infiltration of precipitation into the soil, and conserve
moisture. In Ontario, land is considered to be conservation
tilled or planted when at least 20 to 30% of the soil surface remains
covered with crop residue after planting.
The equipment described
in this handbook can assist the farm operator in achieving these residue
targets. The handbook is organized by conservation tillage or planting
system as described below:
minimum or mulch
tillage - any system that includes some form of tillage in fall
and/or spring in which crop residues are partially incorporated into
the soil. On many soils, 20 to 30% residue cover is effective in
In this handbook, the modified moldboard plow, the chisel plow and
other types of minimum till equipment are considered part of this
drills - a small slit is opened or a narrow strip of soil is
worked by means of a non-powered ripple or fluted courter running
ahead of. or with the seeding units. Chemical weed control generally
substitutes for cultivation.
crop planters - no seedbed preparation is required other than
that provided by various optional non-powered attachments on the
planter itself. The resulting tilled strip of soil in the row area is
generally a maximum of 25 cm (10 in) wide and 15 cm (6 in) deep.
Chemical weed control generally substitutes for cultivation.
planting systems - a ridge of soil is formed when cultivating for
weed control in row crops. The succeeding crops are then planted
directly onto the top of the ridge after the existing crop residue is
removed, usually by non-powered attachments to the planter.
In order to put the
equipment photographs into context, the discussion about each system
includes the following points: equipment modifications, attachments and
costs (when available); field conditions of use; and practical tips for

The handbook takes a
pictorial look at conservation tillage equipment such as: modified
moldboards, chisel plows, minimum till equipment, conservation seed
drills, conservation row crop planters, and ridge till equipment. It
highlights modifications to the various pieces of equipment and gives
some practical tips on how to use the equipment in the field.
The handbook is an
excellent approach to showing farmers some of the conservation equipment
available, modifications to make the equipment more useful and some
practical tips for use. It is ideal for a beginning farmer to review and
get some general information on equipment.
New technology has
developed since this book was written which dates this publication. The
handbook only looks at equipment which is a small part of a conservation
system. Other factors must be considered to make the system work.
