An improvement on LEACH protocol (EZ-LEACH)

2015 2nd International Conference on Knowledge-Based Engineering and Innovation (KBEI), 2015
Wireless sensor network (WSN) refers to a group of spatially dispersed and dedicated sensors for monitoring and recording the physical conditions of the environment and organizing the collected data at a central location. WSNs measure environmental conditions like temperature, sound, pollution levels, humidity, wind speed and direction, pressure, etc ...

Measures for reducing nitrate leaching in orchards:A review.

Environmental Pollution, 2020
Nitrogen (N) is one of the most important nutrients for plant growth. However, improper management of N fertilization in agriculture has led to a large amount of nitrate leaching, which is especially the case in fruit production systems.

Estimating soil nitrate leaching of nitrogen fertilizer from global meta-analysis.

Science of the Total Environment, 2019
Global estimates of soil nitrate leaching of applied nitrogen (N) in agricultural production systems are not imprecise; however, the results of some field experiments have suggested that nitrate leaching responds exponentially rather than linearly to ...
