Demistifying Precision Agriculture

Many at times, farmers in their quest to becoming top farmers strive to minimize cost while increasing their productivity. This is the big reason why every astute farmer MUST embrace the concept of Precision Agriculture. 

I will try and put this in the simplest way possible; Precision agriculture is the approach to farming where crop and soil receives exact amount of inputs where it is needed such that inputs are minimized while the productivity or yield is maximized. This is achieved through use of information technology (IT) Internet of Things (IoT), big data science among other state of the art technological advancements.

The advancements in global positioning systems (GPS) has greatly revolutionized precision agriculture. Gps is actually considered as the backbone to precision agriculture. From gps, systems such as Auto guidance and auto steering has been developed, advanced and greatly used in farm machinery.


Modern farm machinery are fitted with various kinds of devices that enables the farmer to seamlessly perform precision farming. Such devices includes displays fitted within the cabin, steering units used in steering the farm machinery automatically, antennas used in receiving guidance signals (gps, gnss, rtk etc) used in guidance and steering, control modules among others. 

Farm implements have also been advanced with regards to fitting into precision agriculture. Farm implements such as sprayers, planters, spreaders, etc comes with advanced technological capabilities that ensures precise and efficient use of inputs.

Features such as Variable Rate Control, Section Control, crop health monitoring, implement auto height among others are fitted on the implements. 

There are several players in the field of precision agriculture each striving to be as accurate, precise and efficient as possible. Although most of these technologies are developed and distribed by OEMs (original equipment manufacturers), there are several other indepent players who solely develop and distribute the technologies to the clients directly.


Such independent developers includes manufacturers such as trimble and Fjdynamics . They develop the technology in a way that can be retrofited into any farm equipment and distribute the technologies to the farmers.

Research shows that, precision agriculture improves productivity by upto 45% as compared to conventional farming. With precision agriculture, concepts such as controlled traffic (minimizing compaction in the farm by limiting the area used by machinery movement), zero tillage and minimum tillage.

"The only sustainable way of practising agriculture in the 21st century is through practising precision agriculture", Jefferson.

Artificial Intelligence: The Brainy Robot That’s Taking Over (But in a Good Way!)

Imagine you have a super-smart friend who never sleeps, never forgets, and can answer almost any question in seconds. Now, imagine that friend is not a person but a machine. Congratulations! You’ve just met Artificial Intelligence (AI). AI: What’s the Big Deal? In simple words, AI is when computers start acting like they have a brain. No, they’re not plotting world domination (yet), but they can think, learn, and make decisions —just like humans. The only difference? They don’t complain about Mondays, they don’t forget your birthday, and they definitely don’t need coffee breaks. AI is what powers things like: Siri and Alexa (your pocket-sized assistants who sometimes misunderstand you hilariously). Self-driving cars (which are still learning not to panic at roundabouts). Netflix recommendations (yes, AI knows you’re addicted to crime dramas). How is AI Made? Building AI isn’t as easy as assembling IKEA furniture (thankfully). It involves three key ingredients: ...

RTK GNSS vs. PPP: Which High-Precision Technology is Revolutionizing Smart Farming

In today’s fast-evolving agricultural landscape, precision is no longer a luxury—it’s a necessity. As farmers strive to increase efficiency, reduce input costs, and maximize yields, GNSS (Global Navigation Satellite System) technology has become a cornerstone of modern precision agriculture. Two key high-accuracy positioning technologies are leading the way:  Real-Time Kinematic (RTK) GNSS  and  Precise Point Positioning (PPP) . But which one is best suited for your farming operation? Understanding the differences between RTK and PPP can help farmers make informed decisions that enhance productivity, reduce waste, and improve overall farm management. In this article, we break down both technologies, compare their benefits and limitations, and provide real-world examples of their applications in agriculture. Understanding RTK GNSS Real-Time Kinematic (RTK) GNSS  is a technique that enhances positioning accuracy by using a fixed  base station  and...

KCAA Drone Regulations 2020 and How to Get an RPL in Kenya

The Kenya Civil Aviation Authority (KCAA) has implemented new regulations for the use of drones in Kenya. These regulations aim to ensure the safe operation of drones in the country and to protect people, property, and other aircraft. In this blog, we will discuss the KCAA drone regulations 2020 and the process of obtaining a Remote Pilot License (RPL) in Kenya. KCAA Drone Regulations 2020 The KCAA drone regulations 2020 specify the requirements for drone operations in Kenya. Some of the key regulations include: All drones must be registered with the KCAA. Drones must only be operated in designated airspace and within visual line of sight of the operator. Drone operators must have a valid RPL or operate under the supervision of a licensed remote pilot. Drones must not be flown over populated areas or restricted airspace such as airports, military installations, and government buildings. For a complete list of KCAA drone regulations, visit the official website of the Kenya C...
