Sulphur Fertilizer Trial in Dry Edible Beans
This article was written by Chris Gillard, University of Guelph- Ridgetown Campus. Sulphur is an important nutrient in field crops. It is part of the chlorophyll in leaves, two essential amino acids, and rhizobia bacteria need it for nitrogen fixation. Sulphur is mostly stored in soil organic matter (OM), and it is mineralized each summer […]
Agronomy Guide – Soybeans
Overview Soybeans have become the largest row crop by acreage in the province. Over 1.0 million ha (2.47 million acres) of soybeans are grown annually in Ontario. The year 2014was the frst time that acreage reached 1.21 million ha(3.0 million acres). The development of early maturing varieties, adaptability to no-till production, a wide selection of […]
Unit E48: Flat Rack Hay Wagon and CaseIH 885 Loader Tractor
Plot Comments The vehicle was challenging to get aligned with the sensor due to the wagon axles not being perfectly aligned. The tires on the wagon and the tractor had similar weights. The stress for the wagon tires would be expected to be much higher than the tractor in this instance. Notice the consistent level of pressure at […]
Unit E47: Claas Lexion 8800 Class 10 Tracked Combine
Plot Comments The tracks on this combine do a good job to limit pressure at 6 inches. The excessive weight of this combine means that soil stress deeper in the profile will be high regardless of the amount of floatation from the tracks. The rear tire in this instance looks like it is not applying much load […]
Unit E46: Fendt 828 Row Crop Tractor with IF 600/710 Tires + CTIS
Plot Comments The reduced tire pressure in the Field inflated tires (11 psi) on this machine reduces soil stress at the 6 inch depth (E46_B_3), the (E46_A_3) is the same tires inflated to 30psi for road travel by the onboard CTIS system. The data supports the advantages of employing CTIS to optimize tire pressures for […]
Unit E44: Montag Dry Fertilizer Aircart w Tandem 500/45-22.5 Bias + CaseIH 280 Row Crop Tractor w Dual 420s
Plot Comments This shows the response of the air cart (last two peaks on plot). The response is similar on both sides of the machine. The lower response on the left side was due to misalignment with the sensor. […]
Unit 43: Apache 1240 SP Sprayer w 380s
Plot Comments The machine is a self-propelled sprayer. The response shows that the rear axle is much heavier than the front axle suggesting that load sharing could be improved. […]
Unit E41: JD S680 Combine with 1250/45R32 Super Singles
Plot Comments This combine with the large singles showed a relatively low soil pressure at 6 inches despite having a tire pressure that is well above 20 psi. The large footprint of this tire helps the tire float. There is still a high pressure being developed at 12 and 20 inches due to the weight. […]
Unit E40: Nuhn Tandem 5000 Manure Tanker w 30.5LR32 Bias vs 480/80R38 Radial + CaseIH Magnum 300 Row Crop Tractor Both With CTIS
Plot Comments This Unit is another good example of the advantages or Central Tire Inflation. On both the left and right sides the plots show a reduction in soil pressure when tire pressure was lowered. This particular tire on the right hand side is a very round tread face and generates a high soil stress […]
Unit E39: JD 4830 Self Propelled Sprayer w IF380/90 R46 + CTIS
Plot Comments This sprayer was equipped with CTIS however it was not used to test different tire pressures due to a malfunction The plots show the balance between the left side and right side tires. The peaks on the plot show the balance of the machine with most of the weight on the rear tire (last […]
Unit E37: Row Crop Utility Loader Tractor w/wo Hay Bale
Plot Comments This is a small loader tractor with and without a bale. The front right tire was slightly wider than the left side but there was not much of a decrease in soil stress with the wider tire. In both instances the bale added load to the front tire. […]
Unit E36: Standard Gravity Wagon w 65R22.5 Bias vs 445/65R22.5 Radial Tires
Plot Comments This shows a typical gravity wagon with a normal radial and a VF tire. The final peak on the plot E36_L_ 4 would be expected to be higher. However the challenge of aligning both left wheels over the sensor meant that it did not measure under the center of the tread face. There was not a substantial difference […]
Unit E35: Pull Type Dry Fertilizer Spinner Spreader w Tandem 19L-16.1Bias + MF 4710 Utility Row Crop Tractor
Plot Comments The response of the cart is typical of a implement with moderate weight and high inflation tires. Response at the surface is much higher than it could be with a low inflation tire, but the moderate amount of weight does not generate much stress at the 20 inch depth. The response of the […]
Unit E24 + E33: Pull Type JD1910 Dry Fertilizer Aircart w 66×43-25+ JD8520 Row Crop Tractor 480/620 Single vs Duals
Plot Comments Due to alignment the tractor was not able to drive over the sensors so only the cart tires were tested. The round profile of the face of this tires meant that the pressure response was non uniform across the face. This meant that the center of the tire applied more soil load (E24_R_3). The other plot […]
