Urea Inwards Hydroponics - Positive Or Negative ?

When nosotros render nitrogen inwards our hydroponic solutions in that location are ever a several ways inwards which nosotros tin fulfill our plants' needs for this nutrient. The traditional agency is to render nitrogen exclusively every bit nitrate (NO3-) salts, something which is good proven to plough over expert results, high yield crops in addition to amend than soil growth. However it is ever expert to inquire if a combination or the purpose of additional nitrogen sources may improve the outcome of our hydroponic experience. Particularly since plants inwards soil absorb nitrogen every bit nitrate in addition to ammonia it becomes worth bespeak if a ho-hum releasing origin of ammonia- such every bit urea - would improve the yields of our hydroponic system. On this postal service I volition write a petty flake well-nigh the purpose of urea inwards hydroponics in addition to the scientific evidence that in that location is to back upward or turn down its use.

Urea is an organic molecule which piece of cake decomposes inwards H2O to yield ammonia in addition to carbon dioxide. If the media is slightly acidic, the ammonia released volition larn protonated to flat ammonium, a flat of nitrogen which tin live on readily assimilated past times most plants. Moreover, this flat of nitrogen tin besides live on processed past times bacteria to yield nitrate, providing us amongst an additonal - ho-hum release- machinery for nitrate supplementation. Several inquiry groups accept asked themselves if urea would pick out whatever meaning benefits to hydroponics crops. Of item involvement was a report published past times Oda et al, dealing amongst the effects of Urea in addition to nitrate fertilization inwards hydroponics crops using both organic (peatmoss in addition to baggasse), inorganic (rockwoll in addition to sand) media in addition to pure NFT systems.

After doing a report amongst several concentrations of Urea in addition to Nitrate -both past times themselves in addition to combined - this inquiry grouping establish out that Urea does non improve crop yields inwards NFT systems in addition to indeed pure nitrate does the best undertaking when no media is inwards place. When media is introduced, organic media shows a faster Urea to Ammonia conversion but Ammonia to nitrate conversions are faster inwards inorganic media. However, the effect of Urea remains miserable inwards the feel that nitrate-only crops outperformed almost all crops except for around plants grown amongst minor quantities of Urea which proves to live on beneficial inwards the same agency every bit minor additions of ammonia are already known to be.

So inwards the end, is it worth to add together Urea to a hydroponic formulation ? The scientific evidence says that Urea does non accept whatever clear beneficial effect that could non live on gained past times a minor add-on of ammonium salts, something which has already been confirmed past times several studies done on dissimilar flora species. If you lot are planning on starting a novel hydroponics crop adding well-nigh 5-10% of your amount nitrogen every bit ammonium may attempt to live on beneficial but whatever add-on of Urea seems completely unecessary.

Of course, farther inquiry on this dependent area would live on needed to know the effect of nitrate/ammonium/urea combinations to know if the beneficial effects are a sole effect of the presence of minor quantities of ammonia or a virtue of the "regulatory" effects introduced past times Urea every bit a ho-hum unloosen ammonium fertilizer.
