Variable-rate planting - Top Crop Manager.
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.
The objective of our field research was to estimate the economic value, to the farmer, of variable rate seeding (VRS) as compared with uniform rate seeding (URS). We first estimated the correlation between field quality and economically optimal plant density.
Variable rate technologies are continually becoming more common in agricultural production. In 1998 only 2% of U.S. farms had adopted variable rate technologies for fertilizer application and less than 1% of U.S. farms had adopted variable rate seeding technologies (Zhang et al., 2002).
Variable rate seeding is a step in that direction, and the FieldView advanced seed prescription tool can help to make the process easier, faster and more efficient. I wish you well as spring approaches and hope you have a productive year.
Bell is going to also host a field trial on his farm, and he wants to try variable-rate seeding on soybeans. “I had problems with white mould in the back areas of my fields in the soybeans last year, so it’s almost the opposite situation where in those areas I want to cut the population back a little bit because when you get a better stand it’s sometimes more susceptible to white mould.
New variable-rate seeding (VRS) planter technology allows growers to change seeding rates within a field. A couple research papers were written in the past few years discussing the feasibility of using variable-rate technology to improve profit.
Variable-rate seeding (VRS) is a precision agricultural technology that can properly and accurately adjust the seeding rate according to factors such as soil nutrients, light, and water storage capacity, which can not only greatly increase the crop yield, but also reduce the amount of seed used.
