In this blog, we’re going to be looking at agriculture 4.0, the fourth
agricultural revolution.

A brief history of agricultural revolutions in Britain.

First Agricultural Revolution – This represents the transition from hunting
and foraging to forming systems of settled agriculture.

Second Agricultural Revolution – This represents the British agricultural
revolution of the 18th century, a large-scale transition of traditional
agriculture systems to those that were more compact with new machinery,
better drainage and new crops and crop rotations.

Third Agricultural Revolution – This represents the mechanisation and green revolution in post war Britain.

Fourth Agricultural Revolution – This represents Agriculture 4.0, the implementation of emerging technologies such as the internet of things, cloud computing, robotics and artificial intelligenc

The impact of a fourth agricultural revolution.

The move towards a fourth agricultural revolution are for the benefit of productivity, profitability and the environment. Some of the methods in which these are achieved are:

Sensing and monitoring – The measurement of the performance of the farm can be automated by the implementation of sensing technology. This could be physical sensors on the fields, drone imagining or satellite imaging.

Analysis and decision making – Comparing the data collected with a predetermined ideal, in terms of size, quality, colour etc. Deviations from the ideal leads to a correction being made in the farming method.

Correction – Changing a variable in the farming method to adjust the crop to meet the ideal, for example changing the type or volume of fertiliser used on a specific section of a field, or if there has not been enough rainfall to water a field.

Some advantages for farmers include:

Waste and risk reduction – to be able to identify anomalies in crop growth or livestock health and to have the ability to mitigate problems with crop or livestock to achieve as high of a yield as possible.

Increase business efficiency and reduced costs – using automated equipment processes such as irrigation or fertilisation to reduce labour costs and amount of labour required.

Enhanced product yield and product quality – with better quality control a higher yield of a higher quality of crop is achievable.
