What is HUMIFITO? HUMIFITO is a fumigation system designed and manufactured by Novedades Agricolas, based on the foundation of the spraying process by combining compressed air and water. How to use it in greenhouse cultivation? The compressed air is projected against water at a very high speed, breaking the raindrops…

Temperature control in Greenhouses

The setpoints, and periods for temperature and ventilation are set relative to sunrise and sunset. This normally evolves from daytime temperature to night and vice versa, in order to avoid condensation inside the greenhouse. Normally, 2-3 hours before sunrise, the temperature is increased 1-2 ° C per hour, so that…
Lighting installations can be classified into two types according to their application. So for lighting installations for photosynthetic assimilation, we use facilities with high pressure sodium lamps. If the installation is aimed to the management of photoperiod, incandescent lamps are used. Lighting for photosynthetic assimilation The lighting for assimilation, to…
Ventilation is also used to prevent excessive humidity due to perspiration from the culture. This control is performed in order to prevent disease. Humidity excess occur in cold periods, and its effect is more pronounced during changes from night to day. Humification Systems At low relative humidities, humidification systems are…
The Controllers follow a set of guidelines for dosing carbon dioxide into the greenhouse. The setpoint for this parameter is constantly defined according to: The greenhouse heat demand Solar radiation Wind speed Degree of ventilation opening. A series of setpoints are used for this, including the determination of minimum, middle…
Initially we could think that the placement of these solar panels can produce two adverse effects: One on culture And another on the greenhouse structure. The first one, due to the shade produced by photovoltaic panels on planting, thus subtracting a quantity of radiation photosynthetic to plants and shading specific…

Waste Degradation Systems: PHYTOBAC

At this time we can say that It is already available the system that allows the waste degradation: Phytobac Phytobac is a system of biological bed based on the purifying power of the substrate used, which makes a natural degradation of the active substances of plant protection by microorganisms present…
Royal Decree 1311/2012, September 14th , establishes the framework for action to achieve the sustainable use of phytosanitary products. The Directive on Sustainable Use of Pesticides 128/2009 / EC and its transposition into Spanish law by Royal Decree 1311/2012 includes as part of its objectives to protect the aquatic environment…
The attached drawing show a brief outline of what would be the operation of a farm, where we see a local storage products to use on the farm, place for the end product does not reusable, a tanks filling area which allows collecting the product in case of overflow or…

Greenhouses Screens Control

1. Thermal screens: Thermal Screens are closed during the night when the outside temperature exceeds a value with respect to the interior, or when the temperature in the heating circuit exceeds a threshold, completely closing. If the relative humidity exceeds a certain value, they are forced to open proportion to…

Climate Control in Greenhouses

The first climatic controllers in greenhouses were started using at the beginning of the 80s. Since then their possibilities have increasing up to a degree of sophistication that covers almost all the imaginable situations that meet in the physics of a greenhouse. The variables to be controlled in a greenhouse…
