Dry soil conditions can significantly hinder seedling establishment because seeds require moisture to germinate and develop root systems. When soil moisture levels are insufficient, the seeds may not be able to absorb enough water, leading to delayed germination or even seed failure.

Inadequate moisture means that even if the seeds are planted at the correct depth and in the right conditions, they will not be able to utilize the nutrients available in the soil, which can result in poor seedling rates or unhealthy plants. Moisture is critical for metabolic processes necessary for seed germination, and without it, seedlings struggle to survive.

While excessive fertilization, low seed quality, and optimum soil moisture can influence plant growth, they do not pose the same immediate barrier to germination as dry soil. In cases of excessive fertilization, for instance, seedlings can still germinate but might face other issues related to nutrient imbalances. Likewise, low seed quality may result in weaker plants, but if planted under favorable moisture conditions, those seeds might still germinate. Optimum moisture ensures that seeds have the best opportunity to emerge and thrive, further underscoring the importance of adequate soil moisture in determining successful seedling rates.
