I congratulate the editors on the publication of this book on micro irrigation design. Water for food production is clearly one of the grand challenges of the twenty-first century, and it is hoped that this book will help irrigators and famers around the world to increase the adoption of water savings technology such as micro irrigation.”

FINCA ALZAMORA WEATHER DATA AVAILABLE ONLINE


Today a new weather station was installed in the Finca Alzamora, UPRM campus, Mayaguez Puerto Rico.  Data from the weather station are available from two websites:  WeatherLink  or WeatherUnderground.  The WeatherUnderground site allows you to download archived data in a coma delimited text format that can be imported into Excel.  Data being collected include:  air temperature, dew point temperature, RH, wind speed and direction, solar radiation, UV index, soil moisture tension and soil temperature.  A value of the reference evapotranspiration is available on the WeatherLink page.  We are still working out a few kinks, but should have it running smoothly within a few days.

The weather station was purchased with funds from the UPRM NOAA CREST Project.

Photos from a Class Field Trip to the Coloso Valley


On April 25, 2014, students from the TMAG 4035 Soil and Water Management course at  UPRM visited the farm of Sr. Patiño in the Coloso Valley near Aguada, PR.  This post includes some of the pictures that were taken during the field trip.
