متن کاملAlberta Soil Phosphorus Limits Project
Agricultural systems often require added phosphorus to achieve optimum crop and livestock production. The application of soil amendments, such as inorganic fertilizers, manure, biosolids, and waste water, can improve soil fertility and help produce optimum crop yields. However, many of these amendments, particularly organic materials such as animal manure, are often applied in excess of crop nu...
متن کاملTowards Precision Agriculture: Building a Soil Wetness Multi-Hop WSN from First Principles
This work presents the design and implementation of a wireless sensor network (WSN) from first principles, i.e. without the use of commercial WSN platforms. Specifically, a modular multi-hop WSN was built for humidity, temperature and soil wetness measurements, towards precision agriculture applications. We describe the modules developed for radio communication, low-cost sensing, relaying and s...
متن کاملMonitoring soil wetness variations by means of satellite passive microwave observations: the HYDROPTIMET study cases
Soil moisture is an important component of the hydrological cycle. In the framework of modern flood warning systems, the knowledge of soil moisture is crucial, due to the influence on the soil response in terms of infiltrationrunoff. Precipitation-runoff processes, in fact, are related to catchment’s hydrological conditions before the precipitation. Thus, an estimation of these conditions is of...
