(WEEK) - There are more and more job opportunities in agriculture due to technology.

Let’s learn more about ag-engineering with Terry Feldmann at Mauter-Stutz.

Thanks for being with us. Sometimes very confusing even in the industry - what is ag engineering?

Well actually agricultural engineering is very broad -- it can range from people that work for Caterpillar or Case IH, John Deere in more the hydraulics and electronics and-- into more what I do which is mostly with livestock systems and manure systems, structures and environment area.

What is a livestock housing system?

Our expertise here at Mauer-Stutz are a big part of our agricultural services - deal with all the different species of livestock and poultry. We spend a lot of time dealing with manure systems but there’s also quite a bit involved with the indoor environments to create the proper environment for the animals but the bonus is to collect that mature and then the next thing is the utilization of that manure to produce natural gas - anaerobic digestion.

So the way a digester works is it takes organic matter - and when I say it basically the bacteria. We utilize heating that up to around a little over a 100 degrees Fahrenheit to encourage the growth and of methanogenic bacteria that those are the ones that produce take the organic matter out of the manure are a big part of it and make it into methane.

One of the nice pluses when you produce the biogas you do not have to buy power [...] a big plus too is that the effluent after we collect the bio gas from the manure after it’s treated it still has pretty much all those nutrients - nitrogen, phosphorus, potassium, so the farmer can still use it for fertilizing his crops and -- and what it’s cost them buy fertilizer today’s almost hard to fathom to be honest with you.
