SOYLseed
SOYLseed can help you determine the right seed rate to ensure
a healthy and profitable crop is achieved. Establishing a plant population
that is too high can lead to overly thick canopies, increased lodging,
higher disease pressure and unnecessary expenditure on seed. Seed rates
that are too low will result in lower yields and higher weed pressure.
Getting the right plant numbers starts with the correct seed rate.
As well as grain weight, drilling date and variety there
are many variable factors that also need to be considered such as soil
texture, stoniness, cloddiness and general seed bed quality. All of these
can vary across a field. If this variation in the potential seed bed quality
is mapped then a seed rate map can be produced that will deliver the optimum
seed rate across the whole field.
| Stage 1 - Conductivity
Survey
A survey of the soil's physical properties is undertaken.
This starts with a detailed electrical conductivity survey.
Conductivity has a correlation with clay content,
soil depth, stoniness and moisture content. All of these factors
are important in seed bed creation.
Stage 2 - Zoning
The conductivity map is used as the basis for undertaking
a physical soil survey. Areas of similar conductivity values are
zoned and then ground-truthed by an experienced soil scientist.
(see map right)
Each zone is assessed for texture, stone content,
soil depth to subsoil and compaction. This allows the creation of
potential seed rate zones.

Stage 3 - Calculate Seed Rates
Each zone is assessed for the potential seed bed quality
and plant losses that could occur over winter.
For example, an area of high clay content or high
stone content may have high plant losses and therefore a higher
seed rate is required to compensate for this.
The difference in potential establishment can be used
to vary the seed rate around the default rate which is controlled
by drilling date and thousand grain weight.
Stage 4 - Create Variable Rate Seed Application File
The variable seed rate map (right), once finalised,
is converted into a digital file that is compatible with GPS kit
used with a seed drill controller. |
