Laboratorio Nazionale

dell’Irrigazione “P. Celestre”

What LNI is

The National Irrigation laboratory was

created in 1977

This laboratory is a division of the

Department of Agronomy and Agro-

Ecosystem Management of University

of Pisa

Mission

To develop and to improve

application of irrigation techniques by

introducing testing, promotion and

official approval of irrigation materials.

What LNI does

The lab focus on making tests of

irrigation materials and releases

Ve.Pro.L.G.

Software used to verify the working

performances and to plan drip line-

source laterals, in order to save

water and energyMarcello Bertolacci, Ivan Solinas

Ve.Pro.L.G. is a friendly applied software that, after defining the

condition of use in field, can check the potential working performances,

in already installed systems, as well as, in planning stage, it can select

the fit drip line model and suggest the fit length and manner of

application, in order to increase the distribution uniformity and to save

water and energy in drip irrigation.

VeProLG

The software is already equipped with the

performance characteristics of a large number of

drip line source models, tested by the National

Irrigation Laboratory (LNI), but it can also

estimate the working performances of any other

model of drip line, as long as their performance

characteristics are known.

VeProLG

The calculation to estimate the performances of the

laterals is carried out, not through generalized formulas,

but reconstructing step by step the hydraulic of the

working laterals by means of the specific performance

characteristics of the used model of drip line.
