Page B—Corn Talk, Lancaster Farming, Saturday, July 17,1993 ARE WE SUSTAINABLE? Recently I was asked to make a presentation on the sus tainability issues facing com growers in Pennsylvania. Given the concern over sus tainability th£se days, it’s something many of us should be prepared to address, but as I found, it’s a rather complicated subject to deal with. First you need to define sus tainability and that alone is not an easy task. Several of us who have discussed this at length recently came up with some guidelines for “sustainbility” that we feel comfortable with. To be sustainable, a cropping system should be: 1) economi cally viable, 2) have little impact on the environment, 3) minimize its dependence on non-renewable resources, such as energy, 4) be socially accept able to the rest of the popula tion, and 5) minimize its depen dence on external or off-farm inputs. Personally, I can go along with all but the last one since I have a difficult time under standing why we shouldn’t import products that can be pro duced more efficiently some where else.

SYLVANIA MASTER GROWERS OCIATION 'tween The Rows Dr. Greg Roth n State Agronomy isistant Professor Let’s briefly examine each of these issues and some of the sustainability considerations we need to consider about com production in Pennsylvania. Is com production economi cally viable here in the long run? That depends to a large degree on the individual situa tion, but if we look at the big picture we’ll see that com acreage is down in Pennsylva nia by about 400,000 acres in the last 10 years. This means a fair amount of growers have elected not to grow as much com or to participate in govern ment set-aside programs. Much of our economic com petitiveness in the future will depend on our ability to com pete with Midwest com pro ducers. Several issues appear to be important: 1) Can we com pete given the soils and field size considerations we have to work with? 2) Can we produce the consistent quality of com desired by industry? 3) Will low transportation costs con tinue to make it easy to import com into the state? and 4) Can we continue to maintain the access to and afford the tech nology as we have had in the past?

Transpor tation costs may increase in the future and many of the less pro ductive com acres have been taken out of production. We will have to be committed to maintaining our production efficiency, however, to take advantage of these trends. How is com production impacting on the environment? I maintain there are probably five main environmental areas we need to be concerned about and that we are making good progress in each area. These include soil erosion, nitrate leaching, phosphorous buildup in soils, pesticide leaching and runoff, and effects on birds and wildlife. The growth of conservation tillage and the new conserva tion tillage equipment innova tions will help to address the AGRIGENETICS (O®3M TMM soil erosion problem. We hope that new innovations such as the nitrogen soil test and nutri ent management planning can help reduce some of the exces ses of the past and reduce the nitrate leaching problem. Pesticide leaching and runoff should also be declining with new low rate products, reduced dependence on atrazine, the new atrazine regulations, and the decline in the use of some insecticides. Wildlife problems should also be on the decline as some of the more toxic pro ducts have been phased out. If anything, recently it seems as if wildlife is getting the upper hand in many situations and negatively affecting the com. Phosphorous (P) buildup in soils is die one problem that will be difficult to solve, but it results mostly from importing more P on to the farm than we’re taking off and is not necessarily a result of com pro duction. If anything, good com yields should help to reduce this problem. In assessing the sustainabili ty on an individual situation, we should consider all of these fac tors. The best answer is often difficult to arrive at. For exam- lOLLINO 0N...1N THE 90'i pi X-FOLD SETS THE CHALLENGE PULVERIZERS crush clods and firm the soil for better contact between seeds and soil.

SALES CORP EQUIPMENT pie, is it better to no-till and use more pesticides than it is to plow, disk and harrow and use more energy and increase the potential for soil erosion and nutrient runoff? The best answer probably depends upon field specific conditions such as slope, leaching potential, and the mobility of the pesticides. I think that with careful decision making, some growers can approach the level where their impact on the environment is minimal. How dependent are we on nonrcnewable resources such as energy? Com production consumes a substantial amount of energy, but unlike some industries, it produces about three times as much energy in the product as is used. So, on the balance, we are an energy producing industry. Can we be more energy effi cient? I think so, but as in many industries, this often comes down to economic decisions. Questions regarding input deci sions such as hybrid maturities, dryer modifications, N fertiliz er rates, and storage systems all revolve around the cost of energy.
