For a seed to germinate and grow, seed depth must be set at a level where the seed will be placed into moisture. As quick emergence is key to a successful crop stand, seed placement as shallow as possible is ideal. In situations where moisture is limiting and located in the soil at a deeper level than desired, it may be tempting to seed at that deeper depth, often referred to as “chasing moisture”. Consideration must be given to potential precipitation forecasts after the seed is planted as well as soil type. If a seed is placed at a depth where emergence is delayed, potential agronomic risk to the crop becomes a factor.
The consistency of seed depth in the row and across the field plays a major role in both the evenness of the plant stand and overall plant survivability as well. When seeds germinate, emerge and grow before seeds placed next to them, this creates inter-plant competition for moisture and nutrients which reduces plant efficiency and lead to higher seedling mortality. It is very important to check seeding depth in both drills and planters constantly to ensure that consistency is being maintained. Adjustments to implement depth and working speed may be necessary in varying conditions.
