Recommended: Precision agriculture; an ever growing technology
Background
Agricultural methodology and process has been improved and benefitted with new technologies. Precision Agriculture (PA) definition is evolving with technology development. Most precise definition may be “The application of technologies and agronomic principles to manage spatial and temporal variability associated with all aspects of agricultural production for the purpose of improving crop performance and environmental quality”[1]. PA is conceptualized by a system approach to re-organize the total system of agriculture towards a low-input, high-efficiency and sustainable agriculture[2]. As new technologies are emerging, they are also converging which has opened new domains for development is PA. Mainly two key technologies which benefited PA, namely Global Positioning System(GPS) and Geographical Information System(GIS). Furthermore shrinking size of electronic components, mobile computing, advancement in data processing, enhanced communication techniques, Computer vision, Machine learning, advanced control systems and automation has drifted PA to new horizon.
Crop production input optimization is one of the fundamental domain of precision agriculture. It can help manage crop production more efficiently and effectively which directly relates PA with the term sustainability. Use of fertilizers can be optimized with technologies of PA which results in minimization of use of chemicals. Thus Precision agriculture helps in sustaining environment by reducing input of chemicals in natural resources.
Spatial and temporal variables which significantly effects agricultural productions can be monitored and forecasted using PA techniques. Generally two approaches are use to manage variabilities: map-based ...

By implementing new farming techniques provided with the new technological advances in machines we can see abundant harvest in even the poorest third world countries. For example, the Green Revolution has already showed admirable progress in the northern part of India ever since it took start in 1950. By 1997, northern India increased its grain production by 37 percent. This has proven that traditional farming methods are being rendered obsolete. And because by the year 2000, there will be half the land per person in developing countries as there was in 1970, we need to apply ultra-efficient methods to sustain the growing need. Not only does the Green Revolution enhances food output, it also preserves the environment.
Throughout many years, farming has impacted earth’s food supply. Farmers are the key to supplying food for earths’ outrageous population of 7.4 billion people. America has the greatest amount of farmers on earth that supply a large quantity of food for everyone. Iowa, just one of the top food producing states in America. The biggest question in the midwest for Iowan farmers is how do the change of seasons affect them? In Spring, Summer, Fall, and Winter Iowa farmers have to adapt to the change of seasons. Mostly all crop farmers in Iowa plant corn, soybeans, oats, rye, wheat, and hay. In addition, There are also livestock farmers who raise cattle, hogs, sheep, and chickens. Although their differences, they play a great role in our lives to
Soil has distant layers of earth lying above the other, parallel to soil surfaces; this is known as soil horizons. These horizons may be encountered when digging from the surface to bedrock in this order: O, A, E, B, C, and R. These horizons are identified on the basis of their physical attributes, mainly by their color, structure, texture, particle size, as well as th...
The use of commercial drones in the agriculture and framing industry is highly related to the concept of precision agriculture or satellite farming. This is a new management concept emerged in the United States in the 80’s decade. The National Research Council of the USA defines: “Precision agriculture is a management strategy that uses information technologies to bring data from multiple sources to bear on decision associated with crop production”.
Farming in Great Britain has been characterized by technological changes in recent decades which has led to massive increases in yields and improved stock rearing. Much of this change is due to the application of scientific research in plant and stock breeding and improved mechanization. But even today agriculture relies heavily on the physical environment. All crops require a specific range of temperature, moisture, soil ands drainage conditions and these factors can be modified by the farmer but only to a limited degree.
Fertilisers and pesticides are not available in the village itself, although it is available in the nearest town. The adoption of hybrid and improved seed technologies, the use of chemical fertilisers and plant protection measures, mechanization (use of tractors, sprinkler irrigation and power sprayers) and soil and water conservation measures, have been contributing significantly, to increase farm productivity. Genetically modified seeds have been adopted in the village, including Sona Masuri and Hamsa in paddy, GCH-4 in castor and LRG-11, LRG-41, PRG-158, ICPL-87119, ICPH-2671 and ICP-8863 (Maruti) in pigeon pea.
Biosensor has a wide range of application depending on how it is being used. It is use as medical application, industrial application, environmental applications, military application and drug development.
That’s why sustainable agriculture intensification practices are necessary to meet current and future societal needs, employment opportunities, export earnings, economy development and food security. Agriculture Intensification is defined as, “increase in agriculture production per unit of inputs (which maybe labour, land, time, fertilizer, seed, feed or cash) (FAO 2004) and “Yields are increases without adverse environmental impact and without the cultivation of more land (The Royal Society 2009)”. Therefore, it aims to increase agriculture output from the same available land area, while reducing the negative environmental impacts of agricultural technology. For the sustainability, there is dire need to shift the agriculture production system to sustainable agriculture intensification. Literature shows that intensification of agriculture has significant effect on farmers’ livelihoods and environment. In this way intensive production will increase crop yield, better management practices of cultivated land, increase in farm incomes and economy
To fulfill the growing needs of world's rapidly expanding population in a sustainable manner, crop growers must employed different approaches. Technologies such as precision agriculture are a new frontier in management strategy, technology and practices to enhance decision making. Tools such as remote sensing will play a major role in precision agriculture technology where useful data can be obtained quickly to help increase productivity and ultimately, profits. Additionally, innovative scientific methodologies enable and accelerate development of seed varieties with desired traits such as high yield and good drought tolerance. Both approaches when used efficiently and correctly will enhance decision making, reduce costs and risks, increase productivity and profitability to achieve sustainable agriculture.
As agriculture has become more intensive, farmers have become capable of producing higher yields using less labour and less land. Growth of the agriculture has not, however, been an unmixed blessing. It, like every other thing, has its pros and cons. Topsoil depletion, groundwater contamination, the decline of family farms, continued neglect of the living and working conditions for farm labourers, increasing costs of production, and the disintegration of economic and social conditions in rural communities. These are the cons of the new improved agriculture.
Agriculture is an integral part of the general development system. The development of agriculture and sustainable development are interdependent and interrelated in more than one way. Thus to maintain the sustainability of agriculture, the state government encourages the people of the state towards organic farming. Organic farming is considered necessary to conserve natural resources and safeguard our environment. It is, thus, not only eco-friendly farming but also contributes in improving the quality of fruits and vegetables which have a potential export market. Some of the major components of organic farming that has been in practice is the adoption of crop-rotations, enhancement of soil fertility through biological fixation of nitrogen, the addition of organic manures, IPM and use of micro-organisms.

Agriculture is one of the most ancient forms of art and science that ties human development and well-being to natural resources and ecosystems. (Fritz J. Häni, 2007) Sustainable Agriculture is the production of food, fibre, plant and animal products using farming techniques that protect the environment, public health, human communities and animal welfare. (Sustainable Agriculture - The Basics, 2015) Sustainable agriculture is an integrated system of plant and animal production practices having a site – specific application that over the long term will:
Its contribution to PRA is: the complexity, diversity, and risk-proneness of a lot of farming systems, the knowledge and rationality of small and poor farmers, their experimental mindset and behavior and their ability to conduct their own analysis.
