Reply to Photosynthesis, Oxidation & the Energy Equation
Thanks Mark, fascinating, I have to admit I do find it a bit complicated to wrap my head around the Eh-pH thing but in my view it really does confirm that the principles behind regenerative agriculture are absolutely underpinned by science. For me the key points to note from your article is more about what we do with that science – and that is…

Photosynthesis, Oxidation & the Energy Equation
I recently listened to a great podcast interview with Olivier Husson who is pioneering some great work on how soil redox (Eh) affects plant growth. This is not an area you may have heard much about, but it’s well worth looking into. Most are familiar with soil pH and how it can affect nutrient availability, susceptibility attack from pathogens…

Reply to How to Avoid Overgrazing
That’s a great point Kate and I’ve done much deliberating on that matter :-/
What I’ve come to is that, yes, we can use grazing to prolong vegetative growth of annual species to some degree but it all happens pretty quickly in spring and we can only apply this strategy for a limited period of time.
The bottom line is that we want our plants to…

Reply to How to Avoid Overgrazing
The trick in our short growing season with annuals is to try to keep the pasture in a vegetative state- that can be a challenge if you don’t have enough livestock.
What do you think about leaving some paddocks to ‘stockpile’ for summer standing feed and focus on the remaining paddocks for quality. By that I mean moving slow enough to ensure…

One of the most important things we can do for soil and pasture health, which translates to livestock health and productivity, is to avoid overgrazing.
So, what exactly is overgrazing?
Well, it has more to do with how soon we graze a plant than how much of it is grazed.
Plants all need to put on good vegetative growth in order…

Reply to How's our Pasture Going?
No soil air, no soil life.. no soil life, no soil structure .. in the paddocks spread with dam soil that is.

Lower Blackwood LCDC recently ran a workshop on Monitoring and Recording Data for a Pasture Program. Participants got out in the field and had a go at gathering information on the status of their pasture and soil, to identify where things were going well, or not so well.
A range of different methods were explored to get an indication of how… Read more

Reply to Perennial Pasture Species for High Rainfall Mediterranean Regions
Next time I move the sheep I’ll have to see how that compares with the graze at beer can height analogy (ie are the lower leaves also yellowing at beer can height, or 10cm) or does it need to be higher)

Reply to Perennial Pasture Species for High Rainfall Mediterranean Regions
Good question Kate! I wish there was an easy answer :-/
Adequate recovery is not as important for annual species because, let’s face it, they are only around for a short time anyway.
We do however want to get as much good forage out of them as we can in a season and hopefully build some soil too, through good root development and… Read more
