You told us you needed a hard-working, hard-wearing effluent spreader and that's exactly what we've given you. You needed to save on fertiliser costs and manage waste disposal issues. You needed a spreader with a high-capacity vacuum pump. You wanted a spreader designed to take the load for years and we've given you all that and more.
Top quality European components ensure constant, reliable handling of effluent, day in and day out. All of the tanks are manufactured from 5 or 6mm plate steel, with 6mm domed ends and an independent chassis constructed from grade 350 high tensile RHS steel. The tank is mounted to chassis with flexible rubber connections to minimise the stresses that can be transferred back in to the tank during transport around the farm.
The vacuum pumps used are rotary vane type Battioni Pagani pumps, which are very low maintenance, and efficiently handle the day to day duty cycles of a farm effluent spreader.
All tanks are built to an exacting standard, and individually pressure tested well above their recommended working pressure to guarantee the build quality and safety in the field.
Capitalise on the valuable nutrients in your effluent and save on fertiliser costs while increasing pasture productivity. Keep your farm environmentally sound with the Giltrap range of slurry spreaders - combining Giltrap's knowledge of Australasia's demanding farm conditions with European experience delivers a spreader ahead of its class.
Dairy and pig effluent on the farm raises a host of management and compliance issues, but also offers a source of Nitrogen (N), Phosphorous (P), Potassium (K), Sulphur (S) and other trace elements in a form that can be readily applied to pasture and cropping land to increase production. Organic matter in the effluent can improve the soil's water retention, aeration, drainage and tillage characteristics, and application of effluent on to pastoral soils may also increase earthworm numbers.
The fertiliser value of effluent is variable and can only be confirmed by sample testing. On a dairy farm, mineral values can change between milkings, depending on diet, season, age, amount of washdown water used etc. Storage of effluent will also change its composition, as much of the nitrogen in dairy effluent is converted to ammonia during a two-pond oxidation treatment process. However, the following values can be used as a rough guide.
Dairy Effluent From 100 Cows (average)
Nitrogen (N) 590 kg/year
Phosphorous (P) 70 kg/year
Potassium (K) 540 kg/year
Sulphur (S) 80 kg/year
