We have a lot of elderly people who may remember the days of suffering, the days and nights of their fathers, and they could only get some food out of the earth, because they had been poorly managed since their grandfathers. Many modern farmers are faced with another problem, inheriting the legacy of over or "Fallow" soil tillage, and the legacy of the best conservation tillage and the best conservation practices. Now no arable land area ratio is very high, which make a farmer in addition to collect land rent, very difficult to have the energy to land management, land productivity and reduce maintenance of nitrogen from soil erosion to water and air.
Of course, there is a good side, that is, there are more scientific research, environmental monitoring results and related information through the Internet to spread quickly. This makes more and more people in non-agricultural industries realize that the problems of groundwater, surface water and air quality are related to the loss of agricultural nitrogen. The good news is that the city's millennials (1983-2000) and others are interested in the question of who is produced and how it is produced. Farm management and improved productivity enable us all to enjoy a reasonably priced and nutritious meal. However, many citizens do not understand or believe in agricultural science. Many people rely more and more on blogs, twitter and social media that have no scientific basis to form their own views on agriculture. This situation calls for strengthening the process of agricultural production needs to be more transparent, farmers record management measures, so as to be able to track their production behavior and help increase public trust for agricultural products, enhance the management of the farm nitrogen to improve confidence.
More farmers who run their own farms are using newer tools, updated information and new technologies to improve crop yields and to absorb more nitrogen from nitrogen fertilizer. Some people think that the more complex and esoteric crops, soil and nutrient management is necessary, especially in the face of constantly changing climate, frequency and intensity of extreme weather appeared with our predecessors in totally different circumstances. Farmers have a vested interest in understanding the amount of nitrogen fertilizer from the fields and farms, which can reduce nitrogen losses through the best economic means. These advances in understanding and managing the ability to reduce nitrogen losses cannot be achieved without extensive scientific research as well as the cooperation of agricultural and environmental scientists. The ideal partnership should always aim to improve and maintain productivity and farm income, which requires the use of more efficient crop production inputs, especially to consider the balance between the amount of N input and other essential nutrients, as well as real field soil and water resources protection.
For others, they are very surprised to find that those who have not engaged in agriculture than people actually living in the farm farmers know more about the nitrogen content of surface water and groundwater in the agricultural watershed, and air quality monitoring results. Computers, advanced instruments, and space technology make it easy for anyone on the earth to know the quality of a farm and its environment and what is happening. The time has come for people to use only a single factor and target yield to determine a good amount of nitrogen fertilizer. There are better ways to optimize nitrogen management, with newer techniques and tools that can be used to gradually improve nitrogen recovery and nitrogen efficiency on the farm. So, can we all work together better when we are faced with the problem of nitrogen loss in the environment - the legacy left by at least the first two generations of ancestors? If this is not the case, it is impossible for farmers to benefit further from their hard work, to nurture and maintain the sustainable development of society.
