Variable Rate Seed
Establishing a plant population that is too high can lead to overly thick canopies, increased lodging, higher disease pressure and unnecessary expenditure on seed. Conversely, seed rates that are too low will result in lower yields and higher weed pressure. Variable rate seed can help to determine the optimum seed rate for improved crop management, health and profitability.
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. By mapping this variation in the potential seed bed quality, a seed rate map can be produced that will indicate how much seed should be sown at each point across the field for maximum results.
