The Rural Voice, 1989-08, Page 27we were met by close to 100 farmers who had come to attend his annual field day. We even met two fellows from London, Ontario. Carroll's meetings start off on a different foot than most other agricul- tural meetings. He opened with prayer and a reading from II Chronicles 7:14 and Proverbs 6:16. Then he asked: Why do you farm the way you do? Is it because of your neighbours? Is it because of high-powered salesmen? Is it because of your education? And is it pleasing to man or to God? Carroll spent considerable time discussing the herbicide compounds coming on the market. Because of their extreme persistence and many unknowns which are only now show- ing up, he believes that having an active soil biological system is the only way American agriculture will be able to cope in the future. He stated that it's only in the past several years that he is beginning to see earthworms in his soil again. Prior to his switch in 1979 and his total abandonment of herbicides in 1983, the earthworms were gone. Half jokingly, I turned to the fellow sitting beside me and said, "He's got to be kidding". The southerner replied, "Shucks, I ain't seen fishworms on my farm since I was a boy." The soils in this part of Missouri are a sandy, silty clay, and very prone to crusting and compaction. When Carroll started farming the natural biological way in 1979, his organic matter ranged from .7 per cent to .9 per cent. Fields now range around 1.6 to 1.7 per cent. The soil type, com- bined with conventional tillage, a temperate climate, high spring and autumn rainfall, and flood irrigation, makes it very difficult to raise organic matter levels above 1 per cent. These low OM levels plus the use of herbi- cides, insecticides, and high fertilizer rates may explain the non-existence of earthworms. No dry P and K has been applied on Carroll's soil since 1979, but in that time P levels have doubled. How- ever, the potassium levels have gradu- ally declined to the point where he may apply some sulfate of potash this fall. No ordinary potassium chloride for him. It's too high in chloride salts. Carroll uses a corn/soy/wheat rota- tion, but he does plant some double crop (soys after wheat, June 24 plant- ing). His field of 21 -day-old soybeans looked better than most of our 60 -day- old soys. He also plants hairy vetch after his crops are harvested in order to give his fields a soil -binding cover. And as vetch is a leguminous crop, he gains about 50 lbs. of N by the next spring, which in turn lets him cut down on his purchased nitrogen. Carroll has been on ridge tillage the past four years. He's found it an excellent system to control weeds inexpensively. But because of the high rainfall, crusting, etc., consistent stands and irregular emergence has been a problem. As well, a lot of residue has been swept off his field with heavy rains. On one occasion this past spring, they received 14 inches in 48 hours. Carroll's now considering going back to a chisel plow or sweep plow configuration which will bury more trash. And yes, he does spread his residue behind the combine and chop his stalks. We may gripe and complain that we haven't got the new herbicide ammunition the boys in the U.S. have, but I'm telling you, there's a whole bunch of those products that I never want to see here. Well, once out in his fields it was apparent this guy wasn't fooling. While he did have a few more weeds than his brother across the laneway, his corn was better than anything I've seen grown around here. Mind you, we were looking at 120 -day corn planted in April and flood -irrigated. His brother's field of corn was certainly picture perfect. As he farrtrs using conventional methods, there wasn't a weed in sight, and his corn was a deep, dark green from the 220 lbs. of N. Yet the cobs on Carroll's corn were as large and filled to the end, and with much less expense. During the tour someone pulled out a compaction tester and proceeded to probe an area, both ridges and valleys, in a natural biological section of the plots. To a depth of 2 feet the lowest reading was 750 psi and the highest was 900 psi. Walking across the lane - way into his brother's field and again probing in and between rows, the low- est reading came in at 1,200 psi and the highest at 1,400 psi. Obviously, if this area of Missouri couldn't irrigate, it would have some of the most wilted corn you ever saw. Walking back into Carroll's field and to plot 7, which is 36 rows wide and has always been on conventional fertilizer and pesticides, the probe was again put to the test. However, this time they had to find a 200-1b. man to run it. The lowest reading was 1,400 psi and the highest 1,600 psi. There were a number of people walking around shaking their heads and trying the compaction tester for themselves. About this time, the press heard we were there and wanted information on our cropping systems and an explana- tion of our large government subsidies to Canadian farmers. Did we tune this guy in. When we got done with him he couldn't even move his arms. A loans officer with the local Production Credit Association (PCA) also showed up. Asking him how his loans outstanding were, he confessed that business was pretty slow. Farm- ers have done well the past several years. One farmer, he said, operates 3,000 acres and normally needs an line of $500,000 to $1,000,000. This year he didn't need a cent. Land in this 160 to 200 -bushel corn area is trading at $1,500 per acre, if you can find any. When we got back to the airport our pilot informed us that because of heavy thunderstorms to the north we wouldn't be able to fly out as planned. After a shift in our course, we found ourselves heading to Fort Dodge in Webster County, home of some of the highest priced land in the state before the agricultural recession. Once under the clouds nearing Fort Dodge I reckoned we had seen the top of the corn market, unless it doesn't rain from now until October. Even though their corn was 7 to 10 days late going in, it was still way ahead of ours. The area had had 5 inches of rain in the past week and many areas of the state had good, timely rains, even though their subsoil moisture is still in a deficit position. The state AUGUST 1989 25
