The temptation to graze some paddocks a bit tighter than regular might need gotten the perfect of us this fall as we had been effectively conscious of excessive feed prices shifting ahead. For these acres grazed a bit brief, there are alternatives to spice up productiveness or support in long run restoration, considered one of which you’ll be able to implement very quickly: frost seeding.

The perfect window for frost seeding legumes in Iowa is from the top of February by means of early March. Frost seeding, is just broadcasting seed on present pasture when the bottom continues to be frozen. The freeze-thaw cycle strikes the seeds into the soil to determine seed to soil contact and encourage germination.

Is your pasture a very good candidate to frost seed? Think about these elements when assessing the probability for achievement.

  1. Competitors – naked floor or a skinny grass stand vastly enhance the probability of germination and institution. Non-sod forming stands are likely to do higher, although sod grass stands can nonetheless reply effectively when grazed or clipped brief. Weed stress can also be an necessary consideration as a result of after institution, controlling weeds with out killing off the frost seeded legume is difficult.
  2. Soil vitamins and fertility – If the skinny grass stand in an space is because of poor soil relatively than grazing administration, frost seeding with out addressing nutrient deficiencies within the soil will possible result in short-lived outcomes. As a substitute, think about addressing soil shortcomings this fall and interseeding or frostseeding for the subsequent rising season.
  3. Species and charge – Legumes, particularly purple clover and birdsfoot trefoil have proven probably the most success in varied frost seeding trials in Iowa. Grasses might be frost seeded, however with much less success than legumes and will not be really useful. Seeding charges can differ primarily based on how a lot naked floor is current, however generally, a charge extra akin to that utilized in a ready seedbed might be extra profitable. The price of further seed is offset by diminished labor and tillage prices which are required to interseed through different strategies.
  4. Grazing administration post-seeding – Within the first months of the rising season, a stability of grazing or mowing to cut back competitors, whereas avoiding grazing new forage too intently must be achieved to determine a long-lived, productive stand. Subsequently, sacrifice paddocks or calving pastures that might be repeatedly grazed till pasture turnout are poor candidates. Moreover, pastures that won’t be grazed till the top of the spring flush would possibly outcome within the already established grasses choking out newly seeded legumes.
