Targeted fluid/solid dispensing based on sensed seed data or sensed plant data
Seed sensors are present for determining seed placement in a furrow to then target at least one of fluid and solid application with respect to the seed. Plant sensors are present for determining location of plants within a field and then targeting at least one of fluid and solid application with respect to the plant.
1. A material application system for selected application of the material comprising:
an implement for traversing a field;
a sensor disposed on the implement, the sensor to generate seed pulses by detecting seeds being dispensed from a seed meter when the seeds exit a seed tube or seed conveyor or after the seeds exit the seed tube or seed conveyor;
a material applicator disposed on the implement and configured to apply material on the seed, adjacent to the seed, or to both on the seed and adjacent to the seed; and
a control system for controlling the material application system based on the detected seeds wherein the sensor is mounted after the seed tube or seed conveyor at one of the following locations including a seed firmer bracket, within a seed firmer, a rear of a shank of a closing system or between the shank and the closing system, and the closing system.
2. The material application system of claim 1 , wherein the control system controls material application based on implement speed during material application and seed spacing in a furrow.
3. The material application system of claim 1 , wherein the sensor is mounted after the seed has exited the seed tube to sense the seed frequency, wherein the material applicator is configured to apply material between a first seed and a second seed in a furrow.
4. The material application system of claim 1 , wherein the material application system comprises a planter, and the sensor is mounted after the seed has exited the seed tube and mounted at one of the following locations including a seed firmer bracket, within a disc spreader, within a seed firmer, a rear of a shank or between the shank and a closing system, and the closing system.
5. The material application system of claim 4 , wherein the sensor is mounted below the seed tube or seed conveyor.
6. The material application system of claim 4 , wherein the sensor is mounted at a seed firmer bracket.
7. The material application system of claim 4 , wherein the sensor is mounted within a disc spreader.
8. The material application system of claim 4 , wherein the sensor is mounted within a seed firmer.
9. The material application system of claim 4 , wherein the sensor is mounted rear of a shank or between the shank and the closing system.
10. The material application system of claim 4 , wherein the sensor is mounted at the closing system.
11. The material application system of claim 1 , wherein the control system uses the sensed seed pulses to command the material application system to dispense the material either by synchronizing the seed pulses with pulsed material applications or a one to one correspondence between a sensed seed pulse and a pulsed material application.
12. The material application system of claim 1 , wherein the material applicator comprises a flow control valve and a pulsing valve, wherein the flow control valve regulates pressure and flow of fluid to the pulsing valve.
