Using a Jang Seeder on the Farm

A JP-1 Jang seeder is one of the best tools for small-scale organic farms. The benefits are myriad: It doesn’t need perfect soil conditions to run through seeding rows; it is reliable, precise, and easy to use. This single-row seeder is our favorite hand-push tool for increasing efficiency on the farm. 

It singulates seed extremely well, reducing your overall seed cost by not dumping excess seed on the ground. This precise seeding makes Jang one of the best labor-saving tools on your farm as well. It not only speeds up your sowing but also prevents the need to thin your crop. Not having to bend over to plant or thin your row is the icing on the cake.

This article will give you an overview of getting started with your new Jang seeder and some of our favorite tips.  

Parts of the Jang Seeder

Understanding the parts of your seeder will help you to use it efficiently. Familiarize yourself with how each component works in conjunction with the others and how to adjust for different types of seeds. 

1. Drive Wheel - helps pull the seeder across the seed bed evenly. 
2. Press Wheel - firms the soil after planting
3. Narrow Shoe (Furrow Opener) - opens the soil before seed drop and closes it after implantation. 
4. Adjustable Handle - allows you to change height & horizontal push bar location.
5. Chain & Sprockets - changes seed spacing.
6. Sprocket Storage - holds additional sprockets when not in use. 
7. Seed Hopper: Funnel, Retaining pin & clip, Cover/seed gauge, roller, drive sprocket, metering brush - holds and distributes seeds evenly one at a time. 
8. Carrying Handle

Selecting Roller and Sprockets for the Jang Seeder

The Jang seeder will only work with the seed rollers. The seed rollers are selected based on the size of the seeds you need to plant and the spacing you want between plantings. The sprockets are the second half of the spacing setup. 

We carry the most commonly used sizes for market gardeners. Other sizes are available through custom orders; just let us know what you are looking for. 

Steps for selecting the proper rollers and sprockets to get planting:

1. Check the planting guide on the seed package or seed supplier website
2. Use hopper lid or seed packet information to select the correct size roller
3. Determine spacing
4. Check the chart on the side of the sprocket cover or the table below. 
5. Install proper sprockets; don’t forget to put the extra sprockets back on the handle.
6. Replace the cover securely 
7. Test seed distribution and spacing 

Example: Pelleted seeds need a LJ12 Roller. 2” spacing = 9 Front, 14 in back

Using a Seeder on Your Farm

Use the following sequence every time to get the most out of your Jang seeder. The steps below ensure good time management. Train every person on your farm to use the seeder the same way each time they seed a crop. Reinforcing this basic routine on your farm will decrease errors and possible costly crop loss. 

Before seeding, you will need to ensure a smooth, level, weed-free soil surface in your beds. This can be done using hand tools or a BCS tractor. We highly recommend Using Silage Tarp for Organic Weed Control and Bed Prepping; if you are unfamiliar, this article will show you how. 

Order of operations for seeding a crop:

1. Select the proper settings for the crop you want to seed using the tables below. 
2. Open the side case, choose the correct sprockets, and install them on your Jang seeder. (The size you select will be half of what determines the seed spacing for the row.) Putting the front one on before the rear one will be easier. 
3. Ensure the chain is seated on the teeth of both sprockets. 
4. If using small sprockets, install the metal chain tightener. 
5. Once you have the correct sprockets, insert the appropriate seed roller into the hopper. (The size you choose will be the second half of what determines the seed spacing for the row.)
6. Make sure the brush on your hopper is set correctly.
7. Install the hopper well so its sprocket is well seated in the chain.
8. Weigh your seeds for the desired density and add 50%.
9. Add the seeds into the hopper.
10. Adjust shoe depth and soil covering blade as needed. 
11. Plant your rows!

Before you start, always check that the seeds drop properly; otherwise, it can lead to gaps in your seeding. If you have any problems, here are a few tips.

• First, check the sprocket adjustment in the side case.
• Check that the sprocket in the hopper is installed appropriately on its chain.
• Double-check the hopper brush position.
• As you sow, walk in a straight line and at a constant speed. The optimal walking speed is 1.5 MPH, which is a little more than half speed for most people. 
• When you finish the rows, weigh the leftover seeds and calculate the difference between that and your starting weight. This gives you the total amount of seed used. 

Best Practices When Using a Jang Seeder

Consistent seeding requires focus. It is easy to make mistakes when you are distracted. Suggestions for keeping focused:

• Turn off distractions like walkie-talkies and cell phones.
• Focus on the task at hand, not what else needs doing.
• Follow a set routine every time you seed.
• Make a seeding chart that you, and everyone else on the farm, follows for every crop.

Conclusion

For the money, a Jang seeder is one of the best time-saving tools on any small-scale farm. Once you have become comfortable with its use, you can move your whole seeding schedule over to this tool. It will pay for itself by saving you valuable time and with consistent seeding densities, which means you get consistent harvests without wasted space in your beautiful beds!

FAQ-

Why should I buy a Jang Seeder?

-The Jang saves you money by reducing your seed cost by putting seed precisely where you need it, without wasting or overseeding.
-The Jang saves time in seeding, by letting you seed at a walking pace and by not having to go back to thin the crop.
-The Jang makes quick work of reseeding, allowing you to maximize the efficiency of planting succession crops in a tight area like a hoop house.

Can I use a Jang seeder for broadcast seeding?

The Jang is specifically designed to direct seed at very precise spacing in row. For broadcasting seeding you’ll want to utilize a different seeder that is specifically designed for broadcasting. 

How can I switch crops quickly in the field using a seeder?

The removable hopper makes it easy to pour the leftover seed from your previous crop back into its bag while switching rollers. It’s also not uncommon for growers to buy an extra seed hopper and preload the second hopper with another roller. This lets them quickly swap hoppers in the field in a matter of seconds. 

I routinely plant double and triple rows at the same time. Can the Jang accommodate that?

The Jang platform has several configurations that can allow multiple hoppers and rollers on the same frame. Several seeders can even be mounted to a toolbar and pulled behind a tractor for larger-scale production. Let us know what you’re looking to do, and we can discuss special ordering you exactly what you need. 

I routinely plant rows of beans, peas, squash, and corn. What roller do I need?

The JP-1 works best on slightly smaller seeds than these large-seeded crops due to the size of the hopper. For limited rows of larger seeded crops, you can use the rollers suggested in the tables above. You may need to refill the hopper for long rows of large seeds. If you primarily plant beans, peas, squash, and corn we recommend the Jang TD-1 instead which has a larger hopper and accommodates larger seeded species. We’d be happy to consult with you and get you what you need.
