What is the major focus of precision agriculture?

Precision agriculture (PA) is an approach to farm management that uses information technology (IT) to ensure that crops and soil receive exactly what they need for optimum health and productivity. The goal of PA is to ensure profitability, sustainability and protection of the environment.

How precision agriculture is different from conventional agriculture?

A key difference between conventional management and precision agriculture is the application of modern information technologies can be viewed as technologies that improves the efficiency of inputs applied but requires higher investment capital and labor than traditional technology.

Why precision agriculture is important?

The goal of precision farming is to improve agricultural yield and reduce potential environmental risks, while benefits are: Monitor the soil and plant physicochemical parameters: by placing sensors (electrical conductivity, nitrates, temperature, evapotranspiration, radiation, leaf and soil moisture, etc.)

Why precision agriculture is important and sit an example of a precision agriculture?

With precision agriculture, farmers and soils work better, not harder. A better name for precision ag might be “site-specific ag”. Growers are able to take large fields and manage them as though they are a group of small fields. This reduces the misapplication of products and increases crop and farm efficiency.

What is precision agriculture and why is it important PDF?

Precision agriculture is a management concept, which relies on intensive data collection and data processing for guiding targeted actions that improve the efficiency, productivity, and sustainability of agricultural operations.

What are the components of precision agriculture?

Generally, three major components of precision agriculture are information, technology, and management. Base on these three principles, we can define PA in different ways. Precision farming is information-intense.

What is precision agriculture PDF?

Precision Agriculture: “an integrated information- and production-based farming system that is designed to increase long term, site-specific and whole farm production efficiency, productivity andprofitability while minimizing unintended impacts on wildlife and the environment”.

Why precision farming is required for Indian agriculture?

It enables farmers to use crop inputs more efficiently including pesticides, fertilizers, tillage and irrigation water. More effective utilization of inputs will bring in more crop yield and quality without polluting the environment and will result in sustainable agriculture and sustainable development.

How helpful is precision agriculture to individual farmers and the agricultural industry?

The technology can also help farmers decide when to plant and harvest crops. As a result, precision farming can improve time management, reduce water and chemical use, and produce healthier crops and higher yields—all of which benefit farmers’ bottom lines and conserve resources while reducing chemical runoff.


How is precision agriculture used?

Precision agriculture is a technology and information-based system used to manage farm inputs and to identify, analyze, and manage spatial and temporal variability in all aspects of agricultural production system within fields to maximize sustainability, profitability, and environmental safety (McBratney et al., 2005 ). N nutrition can be managed through precision farming methods using modern technological approaches and sensors. Local or remote N sensors could be helpful in sophisticated management practices to assess plant needs for supplemental N ( Schmidt et al., 2002 ). Precision agriculture that allows effective timing and precise application of N has the potential to save N and improves efficiency. Availability of several soil-crop simulation models paved the way to effective N management and assessment of NUE and N loss. These models integrate the effect of soil, weather, cultivar, pest, and other management practices on the growth and yield of crop. Site-specific nutrient recommendations are also made through the use of geographic information system (GIS) and global positioning system (GPS). N recommendation that takes into consideration of soil nitrate or any other N sources such as N credit by previous crop reduces the amount of needed N and improves efficiency. Other agronomic management practices that increase the yield and total N uptake can contribute to higher NUE of either indigenous or applied N sources as prescribed by simulation models. These management practices include insect and weed control, time of planting, planting density, supply of nutrients other than N, and selecting adapted cultivar or hybrid suited for the region and better N uptake.

How does site specific farming contribute to sustainability?

Site-specific farming can contribute in many ways to long-term sustainability of agriculture production, confirming the intuitive idea that precision agriculture should reduce environmental loadings by applying inputs such as fertilisers only where they are needed , when they are needed (Bongiovanni and Lowenberg-Deboer, 2004 ), and in site-specific amounts. Site-specific crop management aims at optimising agriculture production by managing both the crop and the soil with an eye towards the different conditions found in each field.

Why are demonstration farms important?

Some works and reports ( Erickson and Widmar, 2015) have highlighted the essential role of demonstration ‘digital’ farms in promoting the appropriate adoption of precision farming by farmers . The role of these demonstration ‘digital’ farms is also essential to support farmers in making the appropriate technical choices and investments on their own farms. However, the establishment of such digital farms is not easy. Indeed, to maintain the trust of farmers, it cannot be a purely commercial showroom run only by a few companies. Farmers must also have a clear understanding of the specific contexts in which the demonstration farm operates and be able to assess the constraints they themselves face on their own farms (production profitability, interoperability with existing digital tools and services, employee skills and support, etc.) and be able to identify new commercialized solutions that are of potential interest. Meeting all these conditions is not easy and this is certainly why, to our knowledge, there are few examples of digital demonstration farms in the world.

What is site specific management?

Site-specific management requires detailed information about the heterogeneity of fields to adapt soil cultivation, seeding, fertilising, and fungicide and herbicide application to the locally varying conditions. Previously existing soil and plant information seldom matches the requirements either with respect to the intensity of the required information or with respect to the quality of the derived maps to delineate management units. Conventional methods are too costly and time-consuming. Preferably fast, non-contacting and non-destructive methods should be available to obtain the required information. Management recommendations corresponding to within-field site-specific characteristics are rarely available ( Robert, 2001 ). Implementing the knowledge gained in sound management practices is clearly lagging. In this respect some differences between the two land-use systems studied by the FAM project (integrated farming and organic farming) have to be emphasised: Organic farming generally lacks the potential for a short-term on-the-go reaction especially with respect to fertiliser application. Further on, in organic farming, nitrogen, the key nutrient for agricultural production, will mainly enter crop rotation via the symbiotic legume-rhizobium N 2 fixation, i.e. a biological process that already strongly interacts with site-specific conditions as well as organic manure, that delivers plant-available N also strongly in accordance with site-specific conditions.

What is the A-B line on a tractor?

Systems are now available that will perform headland turns as well as in-work steering. The operator sets the initial guidance line (sometimes known as the A-B line) and then tells the on-board computer to steer the machinery parallel to it at a pre-determined distance away from it. The operator can then concentrate on making adjustments to any implements, watching out for problems or observing the crop if it is an operation during crop growth.

What is the application cycle for spatial management?

The application cycle for PA is observation, evaluation, interpretation, targeted management, and observation.

What are the most rapidly adopted agricultural technologies?

Farmers, agricultural companies, and research institutions, especially in developed countries, are moving toward sustainable use of the Earth’s resources, conservation of water, and reducing, if not eliminating, soil erosion while continuing to increase production. Genetically modified crops , the most rapidly adopted agricultural technology ever developed (see Chapter 8 ), are the latest contribution of chemistry to the continuing transformation of agriculture that enables further progress toward, but alone cannot achieve, the ultimate goal of feeding all.

What is precision agriculture?

Precision Agriculture is a way to maintain the economies of scale realized by using big equipment, but using automation and technology to manage cultivation on units smaller then a field. Generally, the smaller the unit of management, the greater the benefit to the plants.

Is NDVI a precision agriculture map?

A colorful NDVI map of a crop. Is that Precision Agriculture? No, but is a useful piece of information that can help manage the field using Precision Agriculture.

Why do farmers use precision agriculture?

They also use precision agriculture practices to apply nutrients, water, seed, and other agricultural inputs to grow more crops in a wide range of soil environments. Precision ag can help farmers know how much and when to apply these inputs.

Why is precision agriculture important?

Question: What is “precision agriculture” and why is it important? Answer: Precision agriculture is one of many modern farming practices that make production more efficient. With precision agriculture, farmers and soils work better, not harder.
