Pressing the seed in the soil by walking on it or pushing it in the soil with a stick or a roller is on of those very old tricks that seem to work with beets, peas, wheat, pop-corn, buckwheat and many other seeds. You plant by pushing them in the soil with the heel of your feet. Use very dry seeds if you want to try this method. For Natural Farming just cut a weed patch with a scythe and instead of broadcasting Seedballs use seeds that you place on the surface of the soil either in rows or broadcast. For larger surface you can use a heavy garden roller for pressing the seeds in the soil.
Frost seeding is another ancient method used mostly to rejuvenate old fields and damaged lawns that can help you make your life easier when gardening or farming. It is done only with small seeds like clover, poppy, chicory, lettuce, radish, cabbage, mustard, flowers... Small seeds are able to dig themselves in the muddy soil that is prevalent in spring and fall weather. When the soil is muddy, tractor drawn planters cannot make it into the fields but weeds are germinating and growing vigorously. A very easy way to outcompete or at least smoother the early season weeds is to frost seed useful vegetables, herbs or green manures like clover or Lucerne. The usual time to do frost seeding is either very late in the fall or very early in the spring. By using plants that like to grow in cooler temperatures you gain a competitive edge with the perennial weeds that also love to grow in cool soil conditions. By frost-seeding clover, poppy and many other cool weather fast growing plants, even quackgrass and many other troublesome weeds can be controled efficiently. This method can also be used to broadcast many small seeded garden plants varieties. All you have to remember is that frost seeding only works reliably with small sized seeds that camouflage themselves easily and will get buried at the first rain or by frost heaving of the soil. Any big seeds like pea, corn or beans very rarely grow when planted by broadcasting them at the surface of the soil. You can also broadcast small seeded summer vegetables that prefer warm soil just before a rain, but this is less reliable than frost seeding.
