Evolution of agricultural technologies of the last decades
Agricultural tractors are part of the equipment to have benefited from mechanical innovations of the twentieth century. If the first models are born in the late nineteenth, it will be a hundred years before they reach the maximum of their performance. The evolution of technologies will have facilitated the improvement of existing systems.
The evolution of engines
The history of farm tractors begins with the improvement of self-propelled plows. Having proven their effectiveness in their field of use, these tools find a new lease of life thanks to the integration of motorization systems. Modernization of commercially available models makes it possible todevelop autonomous energy tools.
Manufacturers are experimenting with several engine solutions, before adopting the majority of diesel. Democratizing this fuel has not been an easy task: suffering from a high compression ratio, it will have taken time to convince. Incorporating gearboxes to agricultural devices, this type of motorization brings a small innovation in the field.
Modern agricultural engines have taken advantage of the manufacturers' experience to appropriate technologies that were initially out of their areas of use. If the electric models start to find their place in the sector, the Diesel engine remains a safe bet. Its slow rotation speed allows it to combine strength, efficiency and performance. Its cost-effectiveness allows work in optimized conditions. Today, a good number of agricultural tractors offer a flex-fuel use. Assuring a low cost of production, they also contribute to simplify the daily lives of farmers.
The mechanical tools of agricultural tractors
Used mainly for plowing, the mechanical tools of agricultural tractors have also undergone a significant evolution during the last 5 decades. The arrival of the soc plow has enabled farmers to work faster, and to have better yields. The furnishing of the earth is now done in a few hours, if it took several days in the past. The essential elements of the plow draw heavily on the structure of the spider. The farm tractor, however, incorporates additional parts that define its identity. These few modifications include wheels ensuring the stability of the various models. The presence of the coulter is preserved for its utility. The modern agricultural tractor completes the action of the coulter and the moldboard.
Among the mechanical tools that have found their place on the device, cap sleeves are probably the most important. Helping to improve the farmer's behavior, these devices allow the axis to perform more precise movements. Le modern tractor (New Holland for example) focuses on the efficiency of its different components to stand out from the old models. The structure of the plow is more imposing, and therefore heavier, than that of the plow from which it is inspired.
The market today has conventional plows, but also specialized models: while some are designed for plowing between trees, others offer a more universal use. Still others offer flexible or semi-rigid teeth suitable for the simultaneous treatment of several aisles.
Evolution of culture techniques
Although they are now considered as high impact elements on climate change, agricultural techniques are first and foremost a lot of practical knowledge widely adopted by farmers. The last 20 years have generated the vast majority of updates in this area. To optimize the agricultural economy, but also to rationalize it in order to control costs, farmers have opted for more and more advanced processes.
The process of soil erosion is the first to have been improved. Developed to preserve the viability and profitability of long-term land, modern techniques better prevent the negative impacts that a poorly controlled activity could have on the environment. In 2019, farming techniques are based on a very precise process. Soil preparation, principles of crop rotation and seedling density evaluation complement the actions on seed selection. Whether they are in line, in pans, in honeycomb trays, in clumps, in seed pellets or under cover, they will determine the quality and quantity of your crops.
New embedded technologies
The development of agricultural techniques is also based on the integration of new embedded technologies. These provide farmers with valuable information on the state of their crops, hygrometry, the imperatives imposed by the weather, or changes to predict according to the realities of the market. We have seen that the use of tools allowing GPS crop monitoring improved not only profitability but also risk management for farmers.
The disadvantages of this "technocratization" of agriculture
If changes in agricultural technologies In a few decades, they have increased tenfold agricultural yields and greatly improved farmers' comfort and workload, and have become highly dependent on fossil fuels and the financial system. Indeed, their costs, acquisition, use and maintenance, are often high.
The modern farmer could become an important producer of biofuels in short cycle and thus greatly reduce its dependence on fossil fuels
