LIGHT AS AN ENVIRONMENTAL FACTOR FOR PLANTS Of all the climatic factors involved in plant development; CO2, temperature, humidity, etc., light is one of the most important. It is an essential factor for the plant to be able to carry out photosynthesis and on which it depends directly in order to synthesise organic matter from…

HOW DOES SALINITY INFLUENCE SOILS? Electrical conductivity (EC) is the capacity of a substance or material to allow the passage of electric current and is generally expressed in dS/m (dS=deciSiemens). La EC is proportional to the concentration of salts in solution and is the most commonly used parameter for measuring salinity. It is essential to…

RELATIVE HUMIDITY IN GREENHOUSES We have already talked about the importance of temperature inside a greenhouse, but today we would like to talk about another equally important factor that is closely related to temperature: relative humidity. Relative humidity is the amount of water contained in the air, and is related to the absolute humidity (amount…

THE IMPORTANCE OF TEMPERATURE FOR GREENHOUSE CULTIVATION One of the advantages of greenhouse cultivation is the control of climatic conditions to ensure better plant development. Among the climatic factors that influence the crop and production is the temperature, which must be between 18-25 ºC for the plant to grow peoperly and bear fruit (see table…
