Slurry Tankers – Low Application of Effluent

Managing land application of farm dairy effluent has often proved to be a challenge in New Zealand, particularly on wet soils where there is a greater risk of subsequent drainage and overland flow contamination of water bodies by nutrients.

Application rates are governed by the width of spread, rate of flow, and travel speed. Rates as low as 1mm can easily be achieved using a Nevada RainWave™, due to its wide spread width.

Using a splash plate, normal application depths are 3-5mm. Application rate needs to match the soil infiltration rate to avoid ponding and run-off. This is easily achievable even with heavy soils thanks to the revolutionary Nevada RainWave™ – a new system of achieving even more control, resulting in low application, and even spread.

Nevada Rainwave™

By using low pressure and an oscillating fan pattern, the Rainwave™ achieves a wider spread and produces larger droplets, meaning virtually no wind drift, so nutrients are spread evenly.

What’s more, by using the Nevada Rainwave™, you’ll get more from your nutrients!

How? As the name suggests, the Rainwave™ uses low pressure to spread nutrients in a gentle rain pattern. This reduces volitisation so nutrients are not lost to the atmosphere.

Benefits of Rainwave™ spreading

• Far superior to splash plate spreading
• Ideal alternative to dropper booms
• Large droplet size, so very minimal wind drift
• Better nutrient use
• Gentle low-pressure rain pattern
• Better for the environment
• Less pasture damage
• Low application depth (1-10mm)
• Safe tractor speeds (less than 7km/h)
• High volume (100m3/h – 200m3/h)
• Very even spread pattern
• Low maintenance
• Handles thick slurry (up to 20% solids)
