In colder regions, reducing energy costs and the ability to retain heat is a priority. The objective is to extend the cultivation period by using passive energies (light, ventilation …) and calories from the soil. The Walipini greenhouses are...
Photosynthesis is a bioenergetic process occurring in chlorophyll cells (located in chloroplasts) when photosynthetic active radiation (PAR) light is present. CO2 is an essential gas for the process of photosynthesis. This gas is present quite...
Raspberry imports to North America have increased in recent years. Raspberry cultivation under protected environment can provide good yield in the fall if the duration of the growing season is long enough. Moreover, raspberries production under...
The "psychrometric diagram" of humid air is a tool to facilitate the representation of air transformations. [...] The basic concept is that there is a relationship between temperature and saturation humidity
Shrimp farming is one of the fastest growing aquaculture sectors in many parts of the world. This sector has grown from a small-scale ancestral activity, in Southeast Asia to a global industry. Open-fields ponds without climate control and...
In general, three crops (vegetables / fruits) are the most represented in North America through the provinces and states. Indeed, tomatoes, peppers and cucumbers are frequently found in Canadian and American greenhouses. [...] Lately, high...
Intensive vegetable production has grown in the Colombian high mountains (> 1000 m elevation) to meet changing food demand in urban markets. The flowers industry is historically a strong in the country more particularly around Medellin and...
Some UV radiation can interfere with growth, development, photosynthesis, flowering, pollination and transpiration...
The concept of positive pressure ventilation consists of mechanically injecting fresh air from outside to inside the greenhouse into the growing area. Positive pressure ventilation allows for maximum exclusion of insects and uniformity of...
