Soilless plant cultivation has found application in many countries, especially in the production of vegetables, fruits and cut flowers. In soilless farming, the yield is five times higher than in normal agriculture. In soilless agriculture, which is carried out with a moving water culture, 16 thousand tomatoes from a seed and 80 tons of products can be obtained from one acre with the right cultivation.
In this agriculture, hormones and medicines are not used, so soilless greenhouses where the products that do not contain residue and find buyers at high prices are grown as the investment area of today and the future.
BHK Greenhouse has carried out hydrophonic production with professional pool, which is the first in our country, by financing the R&D projects of universities.
It is a system based on ensuring that the plants are put into pools at a certain depth and that the nutrients are only taken from the roots and that these nutrients are changed at certain intervals.FLOWING WATER CULTURE
It is the cultivation of plants in the channels where nutrient solutions are continuously or intermittently flowed to the plant roots with a closed system. It is applied in two ways as nutritious film technique (NFT) and deep water culture.
It is the method where the plant roots are suspended in the air, spraying the necessary nutrients to the plant roots continuously or intermittently in the form of fog or vapor. It saves water and fertilizer compared to other systems.
In solid medium culture, organic and inorganic materials can be used separately or together in different proportions by completing each other's features in order to create the most suitable growing environment. These materials can be used such as organic sand, gravel, perlite, vermiculture, volcano tuff, rock wool and plastic foam, such as peat, compost, coconut shell, sawdust, bark, steel husk. These materials can be used alone or mixed with peat or mushroom compost waste. Media cultures are divided into two as open and closed systems according to the application of the nutrient solution.
* Open System: In the open system, the drained solution is thrown from the root of the plant.
* Closed System: In the closed system, the solution drained from the root of the plant is collected and re-circulated in the system. Closed Systems save water and fertilizers as well as open systems, and are more effective in terms of environmental protection.
In this system, nutrient solutions are applied along the root tips in a few mm depth and in a superficial flow to meet the water, nutrient and oxygen requirements of the plants.
In this system, the roots of the plants are placed not in the bottom of the canal but in the deep solution in such a way that the root tips touch.
