Precision agriculture can be defined as “the application of modern information technologies to provide, process and analyze multisource data of high spatial and temporal resolution for decision making and operations in the management of crop production ” (National Research Council, 1997).

What factors influence crop yield?

One factor believed to influence crop yield is soil compaction, since it has a direct impact on soil hydraulic conductivity. As mentioned previously, the cone penetrometer is the soil-strength measuring device that is being used increasingly to map soil compaction level. Since it is a highly variable point measurement, numerous cone index values are needed to obtain proper representation of a field. This limitation of the cone penetrometer has led to the development of alternative devices that can measure and map soil strength in a continuous manner. One such device consists of a texture–soil-compaction sensing system that consists of a simple tine that is instrumented with a load cell to measure soil-cutting force. It also incorporates a dielectric-based soil-moisture sensor, because soil-moisture content influences soil-cutting force significantly. The soil-cutting force, F, is a function of soil bulk density, ρ, texture, ξ, and moisture content, θ, when the device is operated at a constant speed and operating depth; i.e.:

How can precision irrigation be used?

New uses relating to precision irrigation could include applications for mobile devices operating in the cloud to spatially monitor soil moisture, crop growth, and irrigation in real-time via in-field sensor arrays. Other cloud uses include providing data to refine planting and harvest operations, by integrating GPS and GIS data or managing equipment performance (pressures, flow rates, abstractions) at district or catchment scales. RFID tags, which automatically download data, are also becoming more widespread in agriculture. For example, tagging systems have been developed to collect data on the moisture content of straw bales, weight, and in-field position (GPS); in the future, similar cheap, possibly biodegradable, microtags could be deployed across fields to measure seasonal changes in soil moisture, organic content, crop canopy development, and canopy stress, or for monitoring and optimizing energy needs across pressurized irrigation distribution networks ( Carrillo Cobo et al., 2011 ). However, data security issues relating to confidentiality, integrity, availability, and accountability still need to be resolved before cloud technology can be fully integrated into precision irrigation.

What is cloud computing in agriculture?

Put simply, cloud computing involves using networks of remote servers hosted on the internet to store, manage, and process data, rather than hosting information and data on local servers. They generally rely on wireless data transfer and mobile web applications, in combination with other tools and spatial technologies including GPS and GIS. Cloud technology is well established within data-intensive industries, but only recently emerging in agriculture where various applications are being marketed. For example, in the USA, cloud services provide on-farm support from agribusinesses and consultants, for agrochemical application management. Other precision-related tools are now emerging.

What is remote sensing in agriculture?

Remote sensing is generating earth-observation data and analysis results daily from the platforms of satellites, manned/unmanned aircrafts, and ground-based structures. A number of active satellites orbiting earth nowadays are for agricultural remote sensing. These satellites are equipped with one or more sensors that can collect various observation data from the Earth’s surface, including land, water, and atmosphere. Typical agricultural remote sensing systems include visible-NIR (near infrared) (0.4–1.5 mm) sensors for plant vegetation studies, SWIR (short wavelength infrared) (1.5–3 mm) sensors for plant moisture studies, TI (thermal infrared) (3–15 mm) sensors for crop field surface or crop canopy temperature studies, microwave sensors for soil moisture studies, and LiDAR (Light Detection and Ranging) and SAR (Synthetic Aperture Radar) sensors for measuring vegetation structure over agricultural lands. For the higher resolutions, unmanned aerial vehicle (UAV)-based agricultural remote sensing is a special kind of airborne remote sensing with possible monitoring of crop field at ultra-low altitude, and UAV-based remote sensors are contributing significantly to agricultural remote sensing big data. How to rapidly and effectively process and apply the data acquired from UAV agricultural remote-sensing platforms is being studied widely at present.

Why do farmers use drones?

Aside from crop dusting, drones will be able to take continuous shots of crops so farmers can monitor plant health without sending scouts out into the fields. This would allow for more controlled, precise fungicide and insecticide application. Japan has already started using drones to spray their rice fields. By 2010, drones sprayed 30 percent of Japanese rice fields with pesticides. “The Japanese farm hectares sprayed by manned helicopters dropped from 1,328 in 1995 to 57 in 2011, as unmanned helicopter spray rose to 1,000 hectares that year,” according to Wired. The consensus seems to be that American farming will adopt drones rapidly as well if they are approved for widespread use.

How much will the global demand for calories grow over the next 40 years?

With the global demand for calories expected to grow by almost 50% over the next 40 years, the question on many minds is how to produce enough food to feed the world population.

How is remote sensing used in agriculture?

Remote sensing technologies are used to monitor crop conditions. Remote sensing is based on the interaction of electromagnetic radiation with soil and plant material captured as images with sensors that are mounted on various platforms such as satellites, aircraft, or UAS. Precision agriculture applications involve identifying and collecting images using reflectance information from the visible and near infrared bands from either bare soil (to discern patterns of soil moisture, organic matter etc.) and from crop canopies (to estimate crop health/biomass, nutrient deficiencies, crop damage etc.).

What is DSS in farming?

Farmers increasingly have access to an array of quantified data from sensors, cameras, and other devices. These DSS are primarily designed to operate on mobile platforms, such as phone, tablets, and in-cab virtual terminals. Traditional decision support systems ingest these data points and either simply integrate them into a dashboard that enables farmers to make decisions based on the data, or applies algorithms and models to the data input to suggest outputs, based on scientific or statistical models.
