Case Study: Low emissions SlurryKat technology maximises efficiency.
A RANGE of the latest SlurryKat equipment is now responsible for spreading all the slurry produced at an agricultural research institute. This is home to a number of livestock enterprises producing around 4.5 million gallons of slurry per year and farming 800 acres of grass and cereal land.
The end user is slurry spreading using the most efficient technology on the market: SlurryKat Umbilical slurry spreading systems.
SlurryKat CEO, Garth Cairns said: “Being a research centre, the end user required the latest and most efficient slurry technology to process all its own slurry production.
“Due to the distance of some of their land from its slurry source, we use a fleet of ferry tankers with transfer booms which offload into a 65 cubic metre mobile nurse tank.
“This, in turn feeds, a highly efficient umbilical system with direct soil surface application via a 12m Premium Plus™trailing shoe injector to reduce the number of passes in each field.
“There are a number of advantages using this system, including a significant reduction in soil compaction and adhering to the strict ammonia emissions restrictions.
“All applications are monitored with John Deere’s precision NIR and SlurryKat Flowmeter systems which not only control volume spread, but also unit applications of N, P and K,” he said.
Spreading the slurry is a John Deere 155R tractor with Autotrac, coupled to a SlurryKat umbilical trailing shoe system with integrated Doda AFI HD35 high pressure centrifugal pump with inlet chopping system.
Also in the line-up there are; three 16m³ SlurryKat ferrying slurry tankers, a SlurryKat 65m³ mobile nurse tank with integrated Doda pump, SlurryKat front and rear drop off hose reelers, 1,800m of 5” Oroflex hose with patented stainless steel SlurryKat rotating swivel couplings.
Garth said: “We are achieving an application rate of 170 to 240 cubic metres per hour depending on varying factors. The trailing shoe delivers the slurry in a very uniform and precise line on the soil surface without soiling the crop leaves and avoids slurry being smeared by the trailing umbilical hose onto the crop foliage.
“With this reduction of exposed slurry surface area, less ammonia is lost to the atmosphere and more valuable nutrients from the slurry is absorbed and retained in the soil.
“SlurryKat trailing shoes are built to be as light as possible using high quality, strong, yet lightweight UK steel. By using the umbilical system we are keeping soil compaction to a minimum as heavy tankers filled with slurry are being kept off the fields.
“Also, tractors and tankers are not driving over the same gateways and ground to reach the furthest away fields which can erode grass and soil.
“The tractor used on the trailing shoe has low pressure tyres to further reduce soil compaction and field damage,” he said.
These lightweight SlurryKat machines also require less fuel to operate them, compared to other brands, therefore making savings on energy costs too.
SlurryKat are constantly researching and developing their products to ensure they are high performance, reliable and durable.
