Mounding Planters for Wet Conditions

Mounding Planters for Wet Conditions

Plant in wet conditions and peat soils efficiently

The low maintenance PM-range is designed for frost-covered areas and wet conditions

The PM-units are lightweight allowing for lightweight carrier options, helping you keep your capital expenditures in check. The mounding soil cultivation method keeps seedlings safe from moisture and frost and helps combat weevils and other forest pests. Add the PM to your integrated pest management strategy with the ability to apply pesticide simultaneously while planting.

The PM-range can also be employed for digging shallow pits, which makes it extremely suitable for wet conditions. Works best with containerized seedlings from your local tree nursery.

Due to the durable and straightforward design, the PM is easy and inexpensive to operate and maintain, allowing for profitable establishment and reforestation operations.

Pine Weevil

Hylobius abietis or the large pine weevil is a significant pest in young coniferous saplings. The adult weevils cause damage by feeding on the bark of seedlings around the 'collar' of the stem, thus 'ring-barking' the tree seedling, which usually results in its demise. (Source: Hylobius abietis -

Pine weevils breed in the stumps and roots of felled trees. Weevils eat the newly planted young trees during the following summer after harvesting and for the next 2-5 years after regeneration. Typically, the weevil eats pine, but also spruce, larch, and other coniferous species, and sometimes even deciduous trees.
The most effective antidotes to combat weevil damage is in the choice of regeneration methods and the timely application of pesticides.
Direct seeding is more prone to weevil attacks than regeneration by planting seedlings. There are a few reasons for this. First, using soil preparation methods that expose the mineral soil, you minimize the risk of weevil attacks, since the pest does not like to travel on bare ground. In spruce plantations in particular, mounding has proven to be an effective soil preparation method for combating weevils.
You can prevent weevil infestations by treating the seedlings with pesticides. While adding pesticides at the tree nursery to seedlings is common practice, we recommend applying pesticides concurrently with planting, to increase the effect of the application. Having the contractor apply pesticides while reforesting is also more cost-efficient.
Additional benefits of using mechanized silviculture come from the use of containerized or potted seedlings which are more resistant to devastation by the weevil. Burning increases the risk of damage from weevils. However, with mechanized planting, you can avoid burning and use the planter to sweep the planting spot before preparing the soil.

Why You Should Consider Mechanized Silviculture

Reforestation is expensive and slow due to multiple steps

With mechanized planting you can combine many different stages, making the reforesting process fast and more economical overall. Combining the different stages will accelerate forest growth, while improving the quality of work. One upshoot of combining stages is the reduced need for weed control, since weeds do not have time to take root between planting stages. And any stages you can leave from your costings will obviously impact your profits positively!

Availability, organization, cost and safety of skilled personnel

Not everyone wants to do tough silvicultural work in remote locations. By mechanizing your operations, you will be upskilling people with transferrable skills. In addition, a planter will obviously reduce the need for low-skilled manual labor. With the same number of people, you get significantly more results. More results, which are achieved more cost efficiently and with a significant reduction of safety risk. 

A short planting season reduces effective planting time

The reduction of effective planting time will reduce the yield of your forests. With mechanical planting your can work on different process stages simultaneously speeding up your silvicultural operation. Moreover, the mounding soil cultivation method helps prevent damage to plants caused by frost, or by overly moist soil conditions.
