Thanks for the great feedback and the social climate context assessment. I
agree reality is based on practicalities and that is where work can make a
difference to more people and on larger areas of land. I would like to
focus my works towards this end as well, so I definitely benefit from more
exposure to real-world details to balance idealism.

I understand that implementing a full Keyline Design system is both
expensive and difficult to do with permitting in much of the US at least.
Also, the timeline doesn't fit many scientific studies' deadlines and budget
requirements. So I would love to hear the approach taken regarding these
constraints and ways to improve integrating the strategies and patterns of
various system methodologies (i.e. HM, Permaculture, Keyline, etc) for whole
farm planning and decision making.

I agree that Rapid topsoil development is a practical point of focus with
the one of the best, if not the best, return on investment for farmers and
ecosystems. A least change for the greatest effect scenario?

This being the case, my concern with research on the Keyline Design system's
role in Topsoil Development is to consider the role scale plays as the
pattern is applied across landform shapes when designing a research study.
Can we take something that is 'more' accessible such as simply applying
Keyline pattern cultivation (maybe combined with diverse cover cropping on
some areas) and test for the effects on ecosystem processes when it is
applied in a manner that is more comparable to how it is used in whole farm
planning? For example if a test plot is 15 m x 15 m, then does this test
the role of Keyline pattern cultivation and it's effects on hydrologic
function, soil biology, OM content, etc. at the landscape scale. I can see
how it might if 5 or 10 or 100 hectares were pattern cultivated and then
test plots were set up within this area for sampling and the questions asked
and data collected reflected this 'nesting' within a larger system.

In Reno, we are working on some similar projects and are trying to secure
funding to do more. We are working with Keyline pattern cultivation and
some integration of rest of the Keyline Design components, and we are
assessing interest in peri-urban grazing research to see assess if the
multiple needs of weed mitigation, fire protection, non-point source
pollution, and development of ecosystem services can be met through well
planned, well managed grazing businesses.

For this reason, I appreciate any information that applies to working within
the constraints of the current paradigm and how we can interface with this
edge to develop healthy communities and healthy ecosystems. I hope that any
info, background, references, or details of current projects that
demonstrate viable applications of rapid topsoil development will continue
to be shared here to help us all with our works.

Another concern I have is the role science plays in policy. If we can
coordinate quality studies that demonstrate rapid topsoil development, then
we may be able to amplify the outreach and implementation through leveraging
policy. If research doesn't directly affect farmers and ranchers decision
making as much as other manager's experience, then the products of research
might be best focused at the level of policy, which can then feedback into
implementation at the farm or ranch level through other means (perhaps
funding through NRCS grants, etc.). I haven't thought about this in much
detail, so this is a quick and dirty thought on options for cycling the
energy of research back to application.

I look forward to hearing more about people's progress and projects in this
realm.

best to all,
Neil
