Tech In Agriculture Is Opening Up New Opportunities
Agriculture goes hi-tech
Now, things are about to get even more interesting. You can be sure that, in a decade or so, agriculture would be among the most-sought after vocations. The reason being agriculture’s becoming increasingly hi-tech, so much so that it needs technically qualified people to be involved now.
So, what’s happening?
Just look at the agri-lingo. Earlier, when you talked of agriculture, you spoke about fertilisers, pesticides, water pumps, and maybe solar panels. Today, you are talking sensors, robots, drones, images, big data, artificial intelligence, in conjunction with a lot of computing in the backend. Sensors, embedded in the soil, tells the computer the moisture content present in the soil, and the computer, in turn, tells you how much to water and when. There comes precision.
If you have a large farm and a small corner of it gets infected with some disease, in traditional agriculture you wouldn’t know until the disease has spread all over. Today, with images generated from dedicated satellites or drones, the computer easily identifies the malaise that has just begun. And if yours is a smart-farm, a robot is already on its way to snip away parts of the sick plant which is infected.
Hyperspectral imaging and 3D laser scanning provide information about plants across thousands of acres and every little area under the observation of the machine can be measured as a mathematical value. Robotic de-weeders are coming in too. One example is ‘Hortibot’ which can recognise 25 different types of weeds and spray pesticides selectively just over the weeds. Also, if you perform agriculture in a polyhouse, you have instruments that can control temperature, light, and humidity, to meet the exact needs of the plant.
Big data analytics and predictive analytics can alert farmers to problems that are likely to rise such as pests, diseases, or even climatic changes.
Hydroponics are in — you can have your farm in a container, with plants growing in vertical layers with no soil and their roots dipping in nutrient-enriched flowing water. You create the right conditions inside the container for that particular plant. A company in Abu Dhabi is growing tomatoes inside a container. Tomatoes in a desert!
This opens up exciting possibilities because it has completely de-coupled agriculture from its environmental conditions paving the way to creating your own desired condition. For example, saffron, a very valuable plant, grows only in cold climates, but now it can be cultivated anywhere.
