- A pre-disposition for fundamental change and an
awareness that long- term benefits will outweigh the short-term ones,
which are usually positive but may show no immediate advantages over CT.
- Both the farmer and his workers should have a
thorough understanding of the new technology. This implies training and
observation of practicing farmers.
- Correction of soil chemical and physical
properties limiting maximum plant growth, especially low lime and
nutrient status, and hardpans.
- Gradual and planned adoption over several
years, choosing the most favourable fields first and correcting the
limitations of the others.
- A planter or seed drill specifically adapted
for ZT, or a new specialized model must be available.
- Overhaul of the farm sprayer and fitting of new
nozzles, etc.
- First planting in an easy situation and on less
than 10% of total area. Second crop planting into soybean residue is
recommended.
- Avoidance of areas with troublesome perennial
weeds. These should be brought under control first.
- Re-alignment of roads, ditches or contour banks
before adoption, if necessary.
- Availability of technical assistance, even if only from an experienced neighbour.
