Tell me more... What's an Olsen? Why doesn't it matter in your case?Thanks for that.
Most of my ranch would be index 0 or 1 based on their Olsen P, no wonder I am going broke

Thanks.Olsen P is a really simple soil test to establish phosphate levels as an indicator of fertility... IIRC bicarb is the extractant used, and it's done on a volumetric basis
The main problems in terms of relevance here:
My soil is less compacted, so what's going on in the top 4 inches isn't really indicative when your plants have 4 feet of roots - most P is deep, where the biology is
High OM + low bulk density means a skewed reading - remember this is a bicarbonate extract test
And, I don't buy fertiliser as a rule, so I'd expect my phosphate reserves to be very deep, well chelated, and not show up very well on an Olsen test - it's simply designed to sell coals to Newcastle
Nice, thanks for that, it kinda confirms my own thoughts.Thanks.
Just did a bit of googling. This doc has some useful tidbits: http://www.soiltech.co.nz/articles/...FjAFegQIARAB&usg=AOvVaw0aux0hhiFL6iU0lV_2yAyV
In particular:
- Olsen p doesn't account for P available from organic sources (e.g. decomposing organic matter)
- the bicarb solution technique doesn't reflect real life, where water is the solvent in which nutrients (incl P) find their way into plants.
Looks good, the only way to learn what happens at different stock density is to try, observe, and then maybe replan if it works better or worse than the rest.17Cows 1 bull and 4 calves into this this morning
About 0.25 acre what you can see is what they got more or less
Out this evening and back to a round bale.
I’d like a little more off this as grass had booted and gone to seed already, and cows aren't over hungry I can’t leave them over night as it’s a risk if they escape into the new build until they finish there new boundary walls and fences and they would be of down the road
Another 0.25 acre for tomorrow hopefully on the left.
I may let them have this and then let them have the full 0.5 acre for the 3rd day what do you guys think
You can see the seed above.
Once I get this little paddock out the way it will get easier apart from the drinking water situation but Hey ho I’ll work something out with the pizza slices I showed weeks ago.
Infact there maybe no water in that well now due to dry so I may need to create some avenues to creat access back to farm for water roll on Tuesday.
Just comes up with this here, I'm afraid.....
just add music and you could have the making of a Disney classic there.Got most of the cattle out now, finished calving for a bit just a few odd ones till the autumn lot, Its been lovely and warm the last few days, the grass should be growing well now, the hedges and trees are greening up, spring has sprung
It put up the warning here but then let me in.Just comes up with this here, I'm afraid.....

What 30 Years of Study Tell Us About Grazing and Carbon Sequestration
By Kathy Voth and Rachel Gilker / November 13, 2017 / 16 Comments
Has anyone read this series in ‘On Pasture’. I have based a lot of my justification of grazing, in conversation, on grasslands’ ability to seuqester carbon. Well, that’s true- it does, but then it is released at different times- dry periods, overly mature grasses, overgrazing etc-. It is not so much a carbon sink as a carbon marketplace. This is what 30 years of study by many people has shown. This is due to an equilibrium that gets established in mature grasslands- a new seeding would be a different story , of course. The point I am making is that nothing is as simple as I would like it to be. It was a bit of a disappointment to read this article after all my clever speeches.
