Hydroponics Alesiani Fiorino VB Map Hydroponics Hydroponics Sistem Hydroponics Benefit What are Hydroponics? Hydroponics are culture landless, it coltivated on inert substrates with root plants immersed in a nutrient solution where there are elements necessary to growth. Fiorino Alesiani VB “ Hydroponics “ anno 2011/ 2012 Types 1. 2. 3. 4. Hydroponics sistem : NFT ( Nutrition Film Technique ) DWC ( Deep Water Culture ) Ebb Flood Drop Fiorino Alesiani VB “ Hydroponics “ anno 2011/ 2012 NFT In NFT sistem roots of plants are immersed in a subtile films of nutrient solution where plants take nutrient for growth. Fiorino Alesiani VB “ Hydroponics “ anno 2011/ 2012 DWC In DWC sistem roots of plants are steadily immersed in a nutrient solution but this solution is also peroxide by a oxygenator so the plant don’t suffer root asphyxia. Fiorino Alesiani VB “ Hydroponics “ anno 2011/ 2012 Ebb Flood In Ebb Flood sistem nutrient solution often is removed and put back to avoid root asphyxia, ensuring a good oxygenaion to culture. Fiorino Alesiani VB “ Hydroponics “ anno 2011/ 2012 Drop In Drop sistem nutrient solution is pressure in a small pipes and each pipes is connect by a plants to supplying. Fiorino Alesiani VB “ Hydroponics “ anno 2011/ 2012 Quality Profit Ripeness Why grow in hydroponic? Weeds Water Diseases Nutrition Fiorino Alesiani VB “ Hydroponics “ anno 2011/ 2012 Nutrition The solution utilizzated for hydroponics is composed by macroelements (N,P,K) and microelements (Ca,Mg,S,Fe,Br,Mn) in minour amounts, at times not present in solution. Fiorino Alesiani VB “ Hydroponics “ anno 2011/ 2012 Quality 1. 2. 3. The quality is greater to tradizional culture because the crops are: Organically perfect Healthy Usually don’t affected by diseases Fiorino Alesiani VB “ Hydroponics “ anno 2011/ 2012 Diseases The diseases are very low in hydroponic because landless there aren’t bacteria and virus that attack plants. In fact there is a less use of pesticides in hydroponics. Fiorino Alesiani VB “ Hydroponics “ anno 2011/ 2012 Weeds The weeds in hydroponics are absent because we use substrates where there aren’t foreign seem to our culture. -Note: So we don’t use herbicides. Fiorino Alesiani VB “ Hydroponics “ anno 2011/ 2012 Profit The Hydroponics are more remunerative by tradizional crops because with this method we can achieve production 2 to 10 times more. Fiorino Alesiani VB “ Hydroponics “ anno 2011/ 2012 Ripeness The ripeness is an important factor for market of crops and thanks to hydroponics is possible have got every crops indipendement of the season, ensuring fresh produce for the market. Fiorino Alesiani VB “ Hydroponics “ anno 2011/ 2012 Water With hydroponics there is a big saving water, thanks to recirculation of nutrient solution that ensure small losses of water.
