What is circular agriculture

Circular agriculture focuses on using minimal amounts of external inputs, closing nutrients loops, regenerating soils, and minimizing the impact on the environment (see Figure 4). If practiced on a wide scale, circular agriculture can reduce resource requirements and the ecological footprint of agriculture.May 18, 2021


What is a circular food system?

In a circular food economy, food waste becomes valuable, affordable healthy food becomes accessible to everyone and innovation uses a regenerative approach to how food is produced, distributed and consumed.


Why are farm fields circular?

The circular pattern, however, is different from the regular patchwork many people imagine traditional farm fields to be. The shape is the result of the center pivot irrigation, a development of the post-World War II era that profoundly changed the course of American food production.


What is circular economy?

The circular economy is a model of production and consumption, which involves sharing, leasing, reusing, repairing, refurbishing and recycling existing materials and products as long as possible. In this way, the life cycle of products is extended.


What does precision agriculture do?

Precision agriculture gives farmers the ability to more effectively use crop inputs including fertilizers, pesticides, tillage and irrigation water. More effective use of inputs means greater crop yield and(or) quality, without polluting the environment.


How does circle irrigation work?

Center-pivot irrigation (sometimes called central pivot irrigation), also called water-wheel and circle irrigation, is a method of crop irrigation in which equipment rotates around a pivot and crops are watered with sprinklers.


How many acres is a farm circle?

The formula for the area of a circle is: Area = π * radius². If the radius is given in feet, the area is in square feet. To convert from square feet to acres, divide by 43560. So the acreage of a circular area is: Acres = π * radius_in_feet² / 43560.


What are circular products?

Circular products are those that operate within the circular economy model i.e. those products that have reduced or completely no need for virgin resources and are designed with the end of their life in mind.


What is an example of a circular economy?

In a circular economy, manufacturers design products to be reusable. For example, electrical devices are designed in such a way that they are easier to repair. Products and raw materials are also reused as much as possible. For example, by recycling plastic into pellets for making new plastic products.


What are circular materials?

Circular Materials are plastics, natural fibers, metals, etc., that have been recovered from their first/prior use-phase. They have been successfully collected, sorted, reprocessed and are ready for the next life-cycle, in a new product.


What are some examples of precision agriculture?

Highlights: Three common precision agricultural information technologies are global positioning system (GPS) guidance systems, GPS yield and soil monitors/maps, and variable-rate input application technologies (VRT).


Who uses precision ag?

That much was made clear in the USDA’s recent survey, where only four states saw precision-ag adoption on more than half its farms: Iowa (52% adoption), Nebraska (51%), North Dakota (54%) and South Dakota (53%), all major corn or wheat producers that rely heavily on state-of-the-art, GPS-equipped combines.


Is precision agriculture a good idea?

At its core, precision agriculture is designed to improve the efficiency of production on farms. For farmers, this has obvious benefits: they can grow more, and healthier crops on the same amount of land and increase the economic viability of their farms in a way that’s better for the environment.
