1. To begin the germination process, the seed absorbs a certain amount of moisture from its surroundings.
2. In a dry seed bed, absorption occurs after distribution through the seed being in contact with moist soil or being submerged in water.
3. For seeds to make good contact with the soil, soil peds (clods) need to be similar in size to the seed and actually make physical contact with the seed.
4. Seed soaking or seed priming prior to planting expedites the absorption process and is often used to increase the rate of plant establishment.
