Terrestrial systems and precision agriculture essay

A fully functional yield-monitoring system includes a GPS that tags each yield estimate with the current location in the field so the data can be matched with the location. Maybe some important ideas will come out of indoor farming and be successfully adapted at mass scale.

In short, global agriculture might follow the evolution of global manufacturing from hand crafting to mass production to mass customization, giving each plant the benefit of hand crafting, but with the efficiency of mass production. Wireless sensors were used in the system to assist irrigation scheduling based on on-site weather data, remotely sensed data and grower preferences.

Closer, straighter rows or single-seed planting are not about adjusting to small-scale variations across fields as much as being consistently accurate and precise over large areas.

A challenge for crop nutrition management. The same funding problem and solution was repeated in The highest figure for future crop demand7 is based on the assumption that more livestock will be finished in feedlots, thus requiring more grains, whereas the lower two forecasts12,37 assume little change in the overall global proportions of pasture- and feedlot-finished cattle.

We can expect to see implement-mounted sensors that use spectrography to detect soil properties such as mineral nutrient concentration, salinity and sodicity. Likewise, the value of the information is likely to increase as farmers become more familiar with it.

The highest-yielding areas are shown in green, the lower-yielding areas in red. A net expansion of cropland between now and would not necessarily imply that peak cropland is not in sight — only that it will occur at a level higher than today.

Advances in agronomy have to date been at least as important in pushing up yields as has genetics, and there is good reason to think that this will remain the case. Our GPS-driven tractors, harvesters that create detailed yield maps, and seeds that resist common diseases and pests and can thrive at unheard-of plant densities would all seem other-worldly to a s time traveler.

According to CSIRO, Australia [5] "Typically grape yield varies eight to ten-fold under uniform management"; "patterns of yield variation are stable in time and driven by soil and topographic variation"; and "patterns of variation in fruit quality tend to be similar to those for yield, suggesting opportunities for zonal management and selective harvest".

The system performance was compared with a conventional uniform irrigation treatment in a potato field. The technology is currently most advanced in combine-harvested grain crops. Increasingly these decisions are optimized for each field based on location, local weather, and soil type.

Cattle finished in feedlots are fed grains, in contrast to those raised entirely on pasture. Because of the great expense associated with this process, other sources of information such as remote-sensing data and soil electrical-conductivity measurements are often used to stratify the field for purposes of improving the statistical efficiency of soil sampling, as well as to supplement or replace the soil samples themselves.

Debates around agricultural innovation today often center on the use of biotech and, in particular, GMOs. Levels were determined by scouting on a one-per-acre grid. Tailoring the application of water, nutrients, and other inputs to very fine scales — down to the square meter or even individual plants — is increasingly possible, but its potential to boost yields is, at this point, less well established.

While some of these effects, like higher CO2, can boost photosynthesis and yields, increases in droughts, floods, and extreme heat could have major negative impacts. Each sub-region was monitored and controlled by a control sector. Factors underlying grain yield spatial variability in three irrigated wheat fields.

Some of the brighter red areas in this figure correspond to weedy patches. Figure 5 shows high weed-infestation areas in the field.

Precision agriculture is the management of spatial and temporal variability of the fields using ICT. The application in horticultural crops was developed in the last ten years.

Is Precision Agriculture the Way to Peak Cropland?

(1 mention) Milan No-Till For more than 20 years, our Milan center has led the world in no-till research. Background. Climate change and high rates of global carbon emissions have focussed attention on the need for high-quality monitoring systems to assess how much carbon is present in terrestrial systems and how these change over time.

Information Systems in Precision Agriculture and Decision Support Global information on the spatio-temporal variation of parameters driving the Earth’s terrestrial water and energy cycles, such as evapotranspiration (ET) rates and surface soil moisture (SSM), is of key significance.

sensors providing real-time data to an adaptive. Is Precision Agriculture the Way to Peak Cropland? Precision agriculture—a set of technologies that optimize inputs to maximize yields—may be the most important innovation for peaking farming's land footprint in the twenty-first century.
