Our patented mulching machine for mulch spreading

Our mulching machine is a mulch spreader and is the most effective method to spread wood chips evenly in new or established orchards or vineyards. The spread width and volume can be adjusted, or calibrated, to the client’s needs and specifications. Wood chips are ideal for using as a base to produce compost.

These mulch spreaders, called “BioSpread”, can be rented as a service or a client can buy one from Rovic Leers. Reach out to us to discuss our highly effective mulching machine and see how you can benefit from the use of mulch on your property.

The many benefits of spreading mulch in new or established orchards or vineyards

Retains soil moisture

Mulched soil retains moisture for longer periods due to less evapotranspiration. Mulching prevents weed growth, thus saving water.

Prevents soil erosion

Mulching provides a layer acting as a barrier breaking the fall of rainwater and therefore lessening the force of water impact on the soil. Soil erosion is also reduced due to less water run-off and a higher infiltration of rainwater.

Provides for temperature and moisture moderation in soil

Mulching provides a protective layer, decreasing exposure of soil to weather elements such as wind and extreme temperatures. This promotes moderate soil temperatures and moisture content, which in turn encourage earthworm activity.

Suppresses weed germination and growth

Mulch acts as a barrier, limiting sunlight finding its way to stimulate weed germination. Insufficient level of sunlight can cause weed seeds to remain dormant or die after germination. Suppression of weeds contributes to higher yields in fruit, flower, and crop production, by decreasing root competition for nutrients.

Alternative to herbicides in weed control

Nowadays, there is increasing pressure on producers to reduce their use of herbicides. Mulching provides an environmentally friendly and cost-saving solution for controlling weeds.

Improves root and vegetative growth

Improved soil conditions promote root growth, and in turn have a positive effect on vegetative growth. Studies conducted by Baxter (1970) on peach and apple trees in Australia showed up to 63% improvement in mulched trees.

Reduces volume of applied fertiliser

A layer of mulch keeps nutrients from being washed away. Organic mulch can release nutrients into the soil as the organic material decomposes. Studies carried out on apples found that mulching improves fruit size as well as calcium and potassium concentration. Studies have also found that mulch also improves the absorption of nitrogen, phosphorus, and potassium from the soil.

Improves yield and nutrition in fruit production

With improved soil biology, the spreading of roots through a larger soil volume increases the absorption of nutrients, which leads to an increased yield. Studies have found that mulching improves average fruit size and a high-return bloom in the consecutive season.

Enhances microbiology in soil

Applying organic mulch increases the organic matter in the soil. Mulching prevents soil compaction and improves the porosity of soil by improved water infiltration. Higher soil porosity is important for absorption of nutrients, as well as earthworm activity. By increasing earthworm activity, the structure and fertility of the soil is improved. Soil fertility is improved by worm castings that are richer than the surrounding soil, containing nutrients changed into forms that are more effectively absorbed by plants. Burrows caused by earthworm activity create passages for air, water, and roots. Earthworms mix the soil as they create burrows, soil organic matter and humus.
