Mulchers V's Slashers.
Mulchers provide a great alternative to slashers by producing and evenly distributing a finer mulch that decomposes more effectively. The NSW Department of Primary Industry state they are especially suited to the pastures of the lower Hunter Valley and many local farmers have now seen the benefits of using them.
With this procedure the cut material is heavily shredded and defibered within the mulcher and then it is deposited evenly and loosely on the ground as a grass mulch layer. The bacteria in the soil immediately brings about an intensive composting on the surface and the earthworms contribute to the natural recycling. The nutrients organically bound to the mulch material go on supplying the green areas naturally and make mineral slow release fertisers unnecessary. This also reduces the risk of fertiliser leaching out into the groundwater. At the same time the grass mulch layer provides protection against erosion by wind and water and prevents the soil from drying out. The natural cycle of biomass strengthens the soil, activates aeration and encourages humus formation.
This allows soils to take up water and digest rain more efficiently, especially when the rain is heavy, bringing about an increase in water storage capacity, which is important during periods of drought. this also results in green areas being more accessible for both pedestrians and vehicles, avoiding a build up of stagnant moisture in a natural fashion. High grade grasses are encouraged, while poor grasses and felt formation are suppressed. it all looks better, the lawn quality is maintained and the lawn appears greener and healthier.
Although it can be quicker Slashing leaves long stems on the ground that create ungainly windrows that take a lot longer to break down into the soil.Slashers are also more prone to kick up flying objects that were hidden in the grass and these can cause damage to anything nearby. Local Councils have started to use mulchers on roadside verges and have now stopped using slashers on the sides of roads because of the number of insurance claims caused by these machines.
