Large-scale farming automated by a robot

The top of the age composition of small business owners was many in the late 40s, around 1995, while there were many managers in the late 60s around 2015. Over the past two decades, 20 years have been passed. Agriculture has long been said to be "The appearance of Japan 20 years later". In other words, if you look at the current agriculture that is anticipating aging, you can see the appearance of Japanese companies 20 years later. So, what about Japan's agriculture? Let's look at the advanced agricultural zone in detail. The stage is Tokachi area of ​​Hokkaido boasting self-sufficiency of food of 1400%. The average cultivated area in this district is 44ha, but in recent years the class of 100ha has increased, and they are building a model to earn a lot by running a small number of people. Surplus management is commonplace, and annual sales are lightly over 100 million yen, and many take over tens of millions of yen. Speaking of agriculture there is an image that it is small and not profitable, but it is the right reverse. If robotizing farming in the Tokachi area, there is even the possibility of becoming a level comparable to the United States.

Mainly used in the large-scale farm in the Tokachi area is a high-performance, massive agricultural machine made abroad. Very high-cost performance characterizes large-scale agriculture utilizing this. Therefore, in the Tokachi area, it is rapidly spreading. For example, if you use a highly functional variable fertilization technique using sensing technology to measure the concentration of chloroplasts, you can significantly cut fertilizer fee. In large-scale agriculture, the amount is unexpectedly large, so that the introduction cost can be taken in one year. Now autonomous travel tractors with automatic steering with RKT-GPS are also in widespread use, and automation of agriculture is getting widespread. Furthermore, overseas, large-scale agricultural machines with sophisticated design and horsepower are also appearing. We expect that in the next ten years most of the mass farming will be done by robots.

Realized reduced cost through wireless LAN and drone technology

In recent years, no-tillage cultivation has attracted attention. No-tillage farming is environment-friendly agriculture that does not cultivate the soil. In the farm, they have plowed land from long ago. Why dig the ground is because of agricultural machinery, livestock, and human beings stepping on the soil. If you do not tread it down, the soil becomes fluffy like the soil in the forest. A drone has already been able to spray pesticides, but recently a drone that can sow seeds from the sky has also appeared. If harvest can also be done with the drone, no-tillage cultivation becomes possible. If this method becomes widespread, the amount of energy input to agriculture, such as cultivation, will decrease sharply. Currently, there are moves to apply for special zones in the Tokachi area. If it is adopted, high-powered wireless LAN and drone technology can be used; free agriculture will be realized at low cost.

In 2009, the government revised the farmland system and lifted the entry of private enterprises into agriculture to prevent the decrease of the agricultural land area, eliminate idle farmland and accumulate agrarian land to motivated people. Although this has increased to companies entering farming, it is currently the case that they are not doing very well. Why is farm going wrong?

Next time I will explain the wall of data acquisition lying in agriculture and the trend of overseas forces.
