Soil preparation is not necessary when applying temporary seed and mulch?

Soil preparation is an essential step in establishing effective temporary seeding and mulching for erosion control. This process often involves taking measures to improve seed-to-soil contact, which significantly enhances the chances of germination and successful growth. When soil is prepared properly, it can help ensure that seeds can take root and survive against environmental stressors, which is crucial for creating a protective cover that reduces soil erosion.

Temporary seed and mulch function as a short-term measure to protect bare soil from erosion. If the soil is compacted or otherwise unprepared, the seeds may struggle to germinate or may not grow at all, resulting in failed erosion control efforts. Moreover, well-prepared soil ensures that mulch can effectively cover the soil surface and provide necessary moisture retention, influencing the growth of the seeds.

In summary, inadequate soil preparation can lead to poor establishment of vegetation, undermining the goals of the erosion and sediment control measures. Hence, soil preparation is indeed necessary when applying temporary seeds and mulch.
