[Terrapreta] Fossil fueled based fertilizers

[Brian Hans]

Nikolaus,
   
  Good looking work. I think your correct that we need to figure out ways to slow release fert's in a soil mechanism method. In the end, this will be not only an energy AND economy savings but also an environmental footprint savings. 
   
  Im curious where you are getting your polymerized fert's from? 
   
  There is a local company Encap that has somewhat of the same idea. They are going for the higher value end user marketplace because of economics presently but the same techniques, IMO, will be utilized in many largescale ag. settings. http://www.encap.net/Home/tabid/36/Default.aspx

  Dear Sean&die;

Urease is the correct spelling. My approach is more plant adequate that means simulating a slowly enhancing degradation which is normal in a soil where plants start to grow having sufficient water and nutrients. The exudates of the root system is rising with size and age of the plant so microbial life in the roots or rhizosphere is as well improving. That means the release of nitrogen has to improve as well ( more bacteria or bacterial expression means more urease production and as a result more nitrogen liberated from the polymer. At the same time you get more CO2 liberated as well out of this polymer. Culmination normally is reached when you are half the way to seed filling where most times only the accumulated photo syntates are used to finish the job. ( exception would be water logging in soy or resource deviation into enhanced disease fighting). The overall concept is to get as much photo syntates as possible in the pre flowering stage accumulated which means some
 tweaking of the chlorophyll efficiency ( DCPTA  or  MPTA applications) and an early salicylic acid induced disease resistance( viral, bacterial and fungal) so-called SAR or self acquired resistance which will drain a little on the photo syntates but at the end rises overall productivity.
If it is more plant adequate then I think its not un common, its logic.The costs are relative,in general it will cost twice as much then with Urea only but as you can save more then 50% of Urea ist cheaper in the end and the synergistic effects are much higher then without polymer. Try it is working very well and its easy to do.

Best regards Nikolaus
