摘要

.土壤水分是决定作物生长和产量的关键参数。现代农业不仅考虑在田间选定点进行一次土壤水分测量，而且还注重水分监测。了解土壤水分随时间的变化，分析强降雨、强日照和土壤温度变化引起的读数变化，对于未来建模、预测和自动灌溉非常重要。本文旨在介绍一个结合物联网技术开发的土壤水分监测系统，适用于深度达 34 厘米的土壤剖面。该系统以一个八通道时域反射仪为基础，根据介电特性测量土壤湿度。开发的系统集成了介电湿度测量和创新的网络服务器及可视化服务。自主站配备了远距离无线通信和太阳能充电电池。通过对结果的分析，我们可以观察到土壤上层含水量在昼夜周期内的微妙变化。所设计的站将来可用于集成高精度自动田间灌溉系统，并为精准农业获取数据。

Temperature dependence of dielectric soil moisture measurement in an Internet of Things system – a case study

. Soil moisture is a key parameter in determining crop growth and yield. Modern agriculture does not only take into account soil moisture measurements obtained once at selected points in the field, but also focuses on moisture monitoring. Knowledge of the variability over time and analysis of the variation in readings caused by heavy rainfall or strong sunshine and high soil temperature changes is very important for future modelling, prediction and automated irrigation. The aim of this paper is to present a developed soil moisture monitoring system for a soil profile up to 34 cm depth incorporating Internet of Things technologies. The system was built based on an eight-channel time domain reflectometer to measure soil moisture based on dielectric properties. The developed system integrates both dielectric moisture measurement and innovative web-based server and visualisation services. The autonomous station was equipped with a long-range wireless communication and a solar-charged battery. Analysis of the results enabled us to observe the subtle deviations of moisture content of the upper soil layer during diurnal cycles. The designed station can be used in the future to integrate a high accuracy automatic field irrigation system and acquire data for precision agriculture.

期刊介绍： The journal is focused on the soil-plant-atmosphere system. The journal publishes original research and review papers on any subject regarding soil, plant and atmosphere and the interface in between. Manuscripts on postharvest processing and quality of crops are also welcomed. Particularly the journal is focused on the following areas: implications of agricultural land use, soil management and climate change on production of biomass and renewable energy, soil structure, cycling of carbon, water, heat and nutrients, biota, greenhouse gases and environment, soil-plant-atmosphere continuum and ways of its regulation to increase efficiency of water, energy and chemicals in agriculture, postharvest management and processing of agricultural and horticultural products in relation to food quality and safety, mathematical modeling of physical processes affecting environment quality, plant production and postharvest processing, advances in sensors and communication devices to measure and collect information about physical conditions in agricultural and natural environments. Papers accepted in the International Agrophysics should reveal substantial novelty and include thoughtful physical, biological and chemical interpretation and accurate description of the methods used. All manuscripts are initially checked on topic suitability and linguistic quality.
