The greenhouse - Foreword

The sustainable greenhouse model is here studied and presented as an unique organism, that in order to grow (crops) develops its vital function in correlation with the surrounding environment, consuming CO2, solar energy, water, nutrients, and sending out oxygen, gasses and liquid effluents.

To achieve evidence the greenhouse was sub-divided in a scheme with 36 trials, where are tested different conditions of:

  1. soil:
    • "TQ"- standard condition;
    • "Z"- added with zeolites;
    • "C"- added with compost and mycorrhiza.
  2. irrigation:
    • "Imax" - in compliance to the standards issued by Latium Regional Authority;
    • "Ird" - in function of the water request of the soil, monitored through the equipped instruments.
  3. fertilisation:
    • "Cmax" - in compliance to the standards issued by Latium Regional Authority;
    • "Crd" - reduced in function of the physiological and nutritional condition of the plants thanks to the monitoring action achieved by the equipped instruments.

In order to understand how this organism works, many detecting instruments were utilised, monitoring the physiological exchanges between the "greenhouse organism" and the environment. Thanks to the data of the monitoring action are then calculated the fertilisation and irrigation inputs for the "rd" trials.

In order to ease comparison, referring to the defrosting recycling irrigation, the sustainable demonstrative greenhouse (Serra1) was coupled to a conventional greenhouse (Serra2) with disposal irrigation system and conventional farming technologies.

The sustainable greenhouse (Serra1) was equipped with an automatic weather station of the network SIARL-REGIONE LAZIO, that collected and transmited data on-line, in real time till the end of the last crop trial.
