With adequate surface area per machine, and ensuring continuous action of the
Little River Pond Mill® circulators through use of electricity or solar power
(preferably with a battery
lagoon environment can be turned into, and maintained in, an aerobic
or facultative state.
There is less opportunity for nitrate already in solution, in a
lagoon, denitrifying to nitrous oxide in the field since the suspended solids
are significantly reduced thereby potentially preventing the anaerobic
conditions typical in the solids portion of liquid manure. We
have also witnessed very low conversion of ammonium to nitrate so concerns over
nitrate leaching should be minimal. Livestock waste
typically does not need to meet municipal waste water standards for biological
oxygen demand (BOD) or total suspended solids (TSS). With increased machine
numbers and the appropriate surface area for each machine, we could however
potentially produce a fertigation liquid from livestock waste with BOD's and
TSSís that meet municipal guidelines (if required).
An added feature of Little River Pond Mill®
circulator remediated liquid is the fact that it is
homogenous due to the intense circulation action the waste
encounters. This feature makes testing much
quicker, easier, and more reliable.
Note: Proper procedures for sample collection and handling must
Alterations to the manure management plan should be
addressed since the nutrients (form and ratio) in the Little River Pond Mill® circulator processed liquid
livestock manure may be different than those of unprocessed liquid livestock
manure. An example would be the significant decrease in organic nitrogen
in the form of manure and more being contained in microbial bodies.
Typically, unprocessed manure is higher in organic nitrogen
in manure form and this nitrogen
would be slowly released to the soil over time. The nitrogen in the LRPM
processed liquid livestock manure has been exposed to oxygen and therefore a
sizable portion of it may have been mineralized
and in ammonium form thereby making a larger portion of the
nitrogen available to the plant immediately. The fertigation liquid (Little River Pond Mill® circulator
processed liquid livestock manure) can be analyzed a week or so in advance of
pumping (emptying) the lagoon and nutrient additions or dilutions to it can be
made according to crop and field requirements prior to field application.
Note: When using circulators it is
important to ensure foreign materials do not become entangled in the
impeller. Foreign materials will prevent proper circulator action, will
reduce or eliminate any significant benefits that circulation would
typically provide, and may damage the circulator. The management
practice of cleaning the circulator impeller is known as de-ragging. To
decrease the requirement for de-ragging in non-separated lagoon systems,
a small alteration in management practices can prevent a great deal of
work and worry.
