To be honest gepman, in our part of the world we are only just venturing into the green house gas issues and wastewater solutions. Our farms are quite a mix, in my area we have farms as small as 130 cows, 100% manual systems, right up to 5000 cow semi automated systems. NZ has reciently signed up the the Kyoto(spelling) protocol. This has required a huge rethink from the farmers in their attitude towards polution from dairy. Currently Fonterra, the NZ dairy company, is researching solutions to the above issues and have implemented some. I am not really conversant with most of it as my exposure has been from the grass roots, talking to the cockies, and often one sided.
My experience is maintenence, fabrication and hands on. My research has indicated that there is a huge demand for a moble welding service and a local solution to pump and machinery failure. That is the demand that I am intending to meet. I am building a small workshop right in the middle of my intended clientel base and I am fitting out a fourwheel drive vehical with the nessesary tools and equipment.
