Hydromulching vs Hydroseeding

What’s the difference between Hydroseeding and Hydromulching?

HYDROMULCHING, HYDROSEEDING

Whether you’ve reached the end of a construction project or are preparing a highway slope rehabilitation plan, you’ve probably come across the terms ‘hydroseeding’ and ‘hydromulching’ as you research an effective revegetation strategy. Both methods are more economical than laying turf. Hydromulching can reach rough or otherwise inaccessible areas such as high slopes, and produce thicker, healthier vegetation that binds with the ground surface soil to effectively protect against erosion.But while these two terms are often used interchangeably, there are some core differences between the practical applications of hydroseeding and hydromulching:

Hydroseeding

Hydroseeding uses water as a carrier to spray seed and fertiliser onto the seedbed. The hydroseed distribute seed and fertiliser, especially for hard-to-reach areas where alternative seeding methods aren’t easily accomplished.

Hydromulching

Hydromulching is similar to hydroseeding, but it adds a fibre-mulch to the mixture of seed, fertiliser and water. The mulch acts as a cover for the seed, helping it retain moisture for faster germination and growth, while protecting the soil from erosion and prevent the seeds from washing away in the rain.

The hydromulching mix is applied and typically consists of a slurry of seed, fertiliser, water, nitrogen, biopolymer, biologically active soil conditioners, a non toxic green colour dye, and organic mulch fibres which will degrade over several months.

Yield and Coverage Demonstration Video

The table-top demonstration illustrates the greater yield you will consistently get out of every bag of mulch created from Thermally Refined wood fiber.

When comparing the cost per bag of hydraulic mulch, it is essential to consider what you get out of each bag to determine its true value.  The fact of the matter is, you simply get more coverage with a 50-pound bag of mulch produced with Thermally Refined wood fiber than you will get from a 50-pound bag of mulch produced from atmospherically refined fibers.  The greater yield is a result of greater loft within the mulch matrix, which also translates into a better growing environment for seedling emergence compared to denser mulch matrices with less air and water holding potential.

Water-Holding Capacity Demonstration Video

This table top demonstration illustrates the superior absorbency of hydraulic mulch created from
Thermally Refined wood fiber.

The water-holding capacity of hydraulic mulch is critical in two areas: in the tank and on the ground. Inferior fibers that don’t absorb water well don’t mix well in the tank, reducing the shooting distance of a slurry that is more prone to clogging and more difficult to apply evenly. Thermally Refined wood fibers absorb water well to create a more fluid slurry that stays in suspension longer, resulting in fewer clogs, better shooting distance, and more uniform coverage. The added water in the mulch, and the ability to readily reabsorb and hold more water from rain or irrigation, also greatly enhances seed germination and vegetation establishment.
