How do computers help increase agricultural production?

With the use of high technology in agricultural production, "traditional agriculture" is moving towards "precision agriculture". In particular, the use of computers and other advanced technology, not only can automatically monitor the soil moisture, fertility, and the growing environment of the temperature, humidity and wind speed, but also to predict the occurrence of pests and diseases, and at any time to send out an alarm. With these reliable data, farmers will be able to irrigate and fertilize at the right time and in the right amount, and take measures to extinguish pests and diseases just as they appear, thus laying the foundation for high and stable yields in agricultural production.

As we all know, plants need to be irrigated when there is a drought. How to irrigate in a timely manner, with how much water to meet the needs of the crops without causing waste, people are often difficult to grasp. If the soil water content, crop growth and other relevant data into the computer, this problem will be solved. Russia's Fair Plains, some farmers, the use of computers to control the irrigation system, the computer can scientifically select the best irrigation program, so that each piece of land are required to get the amount of water. A company in Florida, the United States, the use of a computerized management system, can be buried in the ground sensors, on time to calculate the precise amount of water and fertilizers required by the crop, so that both to meet the crop on the growth of water and fertilizer needs, but also saves 30% of the cost of irrigation and 50% of the cost of fertilizers. In addition, the data provided by the computer can also be used to determine the type of fertilizer, thus effectively promoting crop production and income.

Pests and diseases are the major enemies of agricultural production. In the past, farmers often used drugs to exterminate pests blindly. For this reason, Japanese scientists have used data provided by computers to control pests and diseases in recent years. They will be the pest population density, growth and reproduction conditions, distribution areas and other relevant data into the computer, the computer calculates the best time to apply drugs, the number and frequency, received twice the result with half the effort. Practice has proved that the use of this method of control of rice blast, rice fly and other pests, the effect is very satisfactory. The United States use computer control of apple orchard pests, the insecticide used than the original reduction of 32.9%, the number of times a year by 12 times to 5 times, per acre of farmland can save $ 30, both to improve economic efficiency, but also to protect the ecological environment.

Correctly forecasting weather conditions is also an important measure to ensure that agricultural production. The French Ministry of Agriculture computerized management system can accurately provide yearly and monthly temperature changes such as graphical interpretation of the curve of information, but also statistics on the rate of change of precipitation and frost-free period to protect the rate, and draw out the whole of France's agro-meteorological seasonal atlas for the guidance of agricultural production.

In agricultural production, due to the computer in all aspects of collaboration, greatly reducing the intensity of labor engaged in agricultural production, according to the scientific to meet the plants, "the demand", both to reduce the cost of production, but also to improve crop yields. Looking ahead, the computer will bring an unprecedented revolution in agricultural production.
