"Thanks to satellite remote sensing technology, which gave us early warning of severe thunderstorms five days in advance, I had time to organize labor for harvesting. Otherwise, we would have suffered huge losses in this season's forage," said Dabuxi, a farmer who grows purple alfalfa in Inner Mongolia, China. A hailstorm a few years ago left a deep impression on him. Without satellite remote sensing technology predicting the hail, losses would have reached 2-3 million yuan.
Remote sensing technology, which many people thought only appeared in high-tech companies, is now widely used in digital agriculture scenarios, becoming the "eyes" that guide agricultural planting and improve production efficiency.
Remote sensing technology has extremely wide applications in agriculture, and its commercial application ratio is rapidly increasing, solving many practical problems for farmers.
What are the applications of satellite remote sensing in agriculture and rural areas? In fact, satellite remote sensing plays an important role in agricultural resource surveys, agricultural production process monitoring, agricultural policy effectiveness evaluation, and rural living environment monitoring.
Through satellites, the actual planting area of a single crop across the country can be observed, and the approximate yield can be calculated based on the yield per variety. At the same time, satellites also observe long-term crop growth, and constantly adjust estimated data based on growth conditions. Growth monitoring can monitor leaf area index, chlorophyll content, nitrogen content, nitrogen accumulation, and other parameters of crops. Based on these parameters, growth evaluation can help monitors calculate fertilization amount and determine the appropriate time for fertilization and irrigation, and growth monitoring data can also be used as the basis for predicting crop quality.
In the agricultural production process, in addition to monitoring crop planting conditions, agricultural remote sensing can also monitor farmland soil moisture and bulk crop diseases.
Satellite remote sensing in agriculture, as a 24-hour monitoring tool in the sky, monitors the ground from another perspective and with other methods. Traditional agriculture depends on the weather, but now technological advances have made it possible to "watch" the weather and improve agriculture to be more precise and intelligent. With satellite remote sensing, high-precision recognition of the ground and monitoring of crops can be achieved, addressing the difficulties of traditional agriculture such as difficult planting, low income, and difficult sales. Through modern scientific and technological help, agricultural land plots can be precisely recognized, crops can be accurately selected for planting according to local conditions, crop yield can be increased, and economic benefits can be increased.
By using satellite remote sensing in agriculture, farmers are willing to work the land, scientific production is promoted, and income is increased. It gradually realizes the transition from traditional planting to "smart" planting, allowing more food to be grown on the land.
Under the push of technology, the mode of agricultural production has changed from traditional "careful cultivation" to modern scientific decision-making and scientific planting. This has not only improved the enthusiasm of farmers for production but also promoted rural economic development. It has changed the current situation of agriculture's reliance on weather conditions and helped farmers improve agricultural production efficiency, stabilize their income, and attract more capital, employment, and entrepreneurial opportunities to flow into rural areas, improving the aging and hollowing out of rural areas.
