Summary

TLDRThis video provides a step-by-step guide on how to calibrate a seeder for optimal forage seed planting. It covers everything from marking the test area to selecting the correct tractor gear and measuring seed output. The process includes choosing the right seeding rate, calculating seed quantities based on the area size, and adjusting the seeder settings to ensure the accurate amount of seeds is dispersed. Practical tips, such as starting with a narrow setting and gradually increasing it, are also provided to help ensure effective planting.

Takeaways

  • 🌱 The planting of forage seeds by broadcast is simple, and the video explains how to adjust the seeder for optimal results using pure seeds like Brachiaria.
  • 📏 First step: Mark the test area by placing stakes 50 meters apart.
  • 🚜 Second step: Select the appropriate tractor gear and speed, recommended to use second gear with RPM between 1,400 and 1,500.
  • ⏱️ Third step: Time how long the tractor takes to cover the 50-meter test area.
  • 🎒 Fourth step: Load one or two bags of seeds into the machine.
  • 🚜 Fifth step: With the tractor stationary, set the selected RPM, open the seed outlet, and activate the power take-off (PTO) to begin seed distribution.
  • 📏 Sixth step: Measure the width of the seeded strip, which is 50 meters long and 6 meters wide, covering 300 square meters.
  • 🧮 Seventh step: Perform a calculation to determine the amount of seeds needed for the test area, e.g., 150 grams for a 300-square-meter plot using the Brachiaria Brizantha variety.
  • 📦 Eighth step: Use a tarp to catch the seeds and weigh the amount distributed in a set time with the tractor's chosen RPM and settings.
  • ⚖️ Ninth step: Adjust the seeder until the correct amount of seeds (150 grams) is dispensed within the cronometered time, starting with a narrow setting and gradually increasing the opening.

Q & A

  • What is the first step in planting forage seeds using the method described?

    -The first step is to fix a stake to mark the starting point of the test area. Then, use a measuring tape to mark 50 meters and fix another stake to mark the end of this area.

  • What tractor settings are recommended for seed planting?

    -It is recommended to use the second gear with a rotation between 1,400 and 1,500 RPM for the planting process.

  • How do you measure the time it takes for the tractor to cover the test area?

    -A stopwatch should be used to record the time it takes for the tractor to cover the 50-meter test area.

  • What should be done after setting the tractor's rotation and speed?

    -With the tractor stopped, the chosen rotation should be set, and the seed outlet opened to the desired setting. Then, engage the power take-off to start releasing the seeds.

  • How do you measure the width of the seeding area?

    -Measure the width of the area where the seeds were spread. In this case, the test area is 50 meters long and 6 meters wide, totaling 300 square meters.

  • How do you calculate the amount of seeds needed for the test area?

    -Using the planting recommendation, for example, Brachiaria brizantha cv. Marandu requires 5 kg of seeds per hectare. Since 1 hectare equals 10,000 square meters, the test area of 300 square meters would need 150 grams of seeds.

  • What is the purpose of using a canvas at the seed outlet?

    -The canvas is used to collect the seeds released by the seeder over a certain time, allowing the operator to weigh the seeds and determine if the correct amount is being released.

  • How is the correct seed output determined?

    -With the tractor stopped and set to the chosen working rotation, engage the power take-off and release the seeds for the time recorded earlier. Then, weigh the seeds collected in the canvas and adjust the seeder until the desired output, in this case 150 grams, is achieved.

  • What is a tip for adjusting the seeder's opening?

    -Start with a smaller opening and gradually increase it until the desired seed output is reached.

  • When is the seeder considered correctly calibrated?

    -The seeder is correctly calibrated when it releases the target amount of seeds (e.g., 150 grams) within the time recorded for the test area.
