What is agriculture explain?
What is agriculture explain?
Agriculture is the science, art and practice of cultivating plants and livestock. Selective breeding and modern practices in animal husbandry have similarly increased the output of meat, but have raised concerns about animal welfare and environmental damage.
What are the objectives of precision farming?
Precision Farming and its Objective Precision farming aims to improve crop performance and environmental quality. It is defined as the application of technologies and principles to manage spatial and temporal variability associated with all aspects of agricultural production (Pierce and Nowak, 1999).
What three main elements does precision agriculture rely on?
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.
Why is agriculture important to humans?
Agriculture is important to human beings because it forms the basis for food security. It helps human beings grow the most ideal food crops and raise the right animals with accordance to environmental factors.
What do we mean by agriculture?
Agriculture is the art and science of cultivating the soil, growing crops and raising livestock. It includes the preparation of plant and animal products for people to use and their distribution to markets. These products, as well as the agricultural methods used, may vary from one part of the world to another.
What is the impact of nanotechnology in our life?
Nanotechnology has the huge potential to transform people’s lives for the better. We start using cheap, lightweight solar plastics, which makes solar energy widely available. Nanoparticles can clean up toxic chemical spills, as well as air-borne pollutants.
What is an example of precision agriculture?
One example of a precision agriculture practice is to evaluate the natural soil variability of a field. If the soil in one area holds water better, crops can be planted more densely and irrigation can be sparing. Or, if the plot is used for grazing, more cattle can graze than a similar area of poorer quality soil.
What are possible impacts of nanotechnology?
Major benefits of nanotechnology include improved manufacturing methods, water purification systems, energy systems, physical enhancement, nanomedicine, better food production methods, nutrition and large-scale infrastructure auto-fabrication.
What is the concept of nanotechnology?
Nanotechnology is the understanding and control of matter at dimensions between approximately 1 and 100 nanometers, where unique phenomena enable novel applications. …
How can we use nanotechnology in medicine?
Medical applications include special materials for wound dressings and surgical textiles, materials used in implants, tissue engineering and artificial organ components. Nanofibers made of carbon also hold promise for medical imaging and precise scientific measurement tools.
Why precision agriculture is important?
Precision farming is about managing variations in the field accurately to grow more food using fewer resources and reducing production costs. The goal of precision farming is to improve agricultural yield and reduce potential environmental risks, while benefits are: Provide better information for management decisions.
What are the potential applications of nanotechnology in agriculture?
The significant interests of using nanotechnology in agriculture includes specific applications like nanofertilizers and nanopesticides to trail products and nutrients levels to increase the productivity without decontamination of soils, waters, and protection against several insect pest and microbial diseases.
What are advantages of nanotechnology?
Nanotechnology: Advantages and Disadvantages Advances in disease treatments, such as cancer. Better imaging and diagnostic equipment. Energy-efficient products such as fuel and solar cells. Improvements in manufacturing that allow for durable, light-weight, efficient production tools.
Why do we need nanotechnology?
Nanotechnology also lowers costs, produces stronger and lighter wind turbines, improves fuel efficiency and, thanks to the thermal insulation of some nanocomponents, can save energy. The properties of some nanomaterials make them ideal for improving early diagnosis and treatment of neurodegenerative diseases or cancer.
How does precision agriculture affect the environment?
The study identified that precision agriculture techniques have a positive contribution to greenhouse gas reduction. Nutrient and water management have a direct contribution, in particular the so-called Variable Rate Technology for nutrients application because of the lowered N2O emissions.
What is agriculture in simple words?
: the science, art, or practice of cultivating the soil, producing crops, and raising livestock and in varying degrees the preparation and marketing of the resulting products cleared the land to use it for agriculture.
Who invented precision agriculture?
