do you have the coordinates GPS? It would be interesting to see the NDVI results on the Copernicus Browser.

Does Copernicus allow you to see satellite imagery over time? What does the NDVI tell you? I've had a quick look, Looks like it'll be good for recording land transformation over time!

yes you can create timelapses etc.
You the NDVI (Normalized difference vegetation index) basically gives you an idea of the density and health of vegetation, mosty based on photosynthetic activity.
Very popular with some of the top no till boys over here.

It's true though.nothing original yet. All stuff that you would have picked up on here over the thread. However, nice bitesize chapters to read in a very personable style. I love the way he crunches numbers to make you relate to stocking densities rather than stocking rates.
Then there is this little gem about Management Intensive Grazing which has cropped up on here so often...it's as if he has been to the same school of analogies as @Kiwi Pete !View attachment 1155747
All those books people have read, makes me wonder what would have been possible if they had spent an extra couple of hundred hours out doing something else.

What is growing on your land? Pasture? What is growing on the neighbours lands?
Right now the best looking fields around mine (neighbours fields) are Italian ryegrass or well rested, well functioning pastures.
Unsurprisingly wheat looks awful with all that bare soil.
In the summer the fields of maize are head and shoulders above the rest.
You can also use the phone app 'onesoil', although it is a litle more basic. One can easily spot the areas where the cows have grazed and where the pugging during this wet weather has been more or less intense.
I'll post a screenshot.

you can see thé areas where thé cows have been (yellow bottom left) and thé dark green areas is where they have yet to graze. I have added in thé neighbours wheat field (very yellow) at thé top to give some comparison.
When he puts a C4 grass liké maize in that fields, during thé summer. it is almost thé opposite effect.

The site has changed a bit, but this link got me nearly back there.
Esri | Sentinel-2 Land Cover Explorer
This application displays the land use/land cover (LULC) timeseries layer derived from ESA Sentinel-2 imagery at 10m resolution.
There is a site called National Library of Scotland, which has historic maps, and I found my way from there, it was a couple of years ago at least (I see from my screenshot we were on page 949 of this thread) Could spend a whole Sunday looking at old maps!

Here is a screenshot from the drought of 2022.
The dark area encircled in blue is my neighbors maize on comparable light land..
The light areas are stockpiled (waist high) pasture.
The dark area to the northeast is maize on good land.
The very pale area to the north is wheat (post recolte)
The other dark areas are woodland.
I can see the technical interest on having C4 grasses included in the farm. But is it worth the financial and social risks?

Ours is all PP, most will have been reseeded until about 1990, and barring a couple of shaws that were removed the fields are about the same in 1850.
Having played with different dates on the app, I see the neighbouring field that most of the time looks like bare ground, suddenly turns a darker green than any of ours, I think 2022 was drilled osr and marigold companion or something similar.

makes sense. thé annual species (ok bisannuel) have a higher photosynthetic rate then the perennials as they have to grow fast in a short amount of time.
also one of thé many avantages of sowing annual species as nurse crops for a new grass ley. or interseeding annuals into existing pp etc.

understood lucerne/alfalfa was a dry area crop, grown where moisture is deficient.
therefor surprised to find it as a water hungry crop, and the growing of it, with irrigation, has very seriously depleted water supply, in some states in USA, as much as introducing rules to stop it being exported/grown, and withdrawing leases, bought by other countries, to stop the indiscriminate use of said water.
Saudi Arabia is growing intensively in US to feed cattle in Saudi, and other countries as well.
Carbon foot print, lucerne USA to Saudi, very environmentally friendly. And people think planting a few trees, will sort the matter out
and a happy new year.

We are acid sands so totally different!
Fortunately for you I think most legumes prefer alkaline. Timothy, ryegrass, fescues, plantain, trefoil, white clover would all work well, I'd guess.

l wonder after 70 yrs applying acidic nitrogen fert, how we have actually increased the ph of our soils.
not so many years ago, soil testing would leave us with ph of 5 to 5.5, with some areas starting with a 4.
more recent testing, and lower N use, are showing more like 5.5 to 6. Now the other difference, older tests were done 'on site' using litmus paper, and colour chart, recent ones lab tested.
which one is more accurate, or is the lower ph being corrected, slowly by nature, and less N use ?

Yes even sainfoin and lucerne will grow here, unless it's a flat poorly drained area.

most lucerne produced for hay here is under irrigation . . .
it is certainly very good at drying country out & extracting every last drop of moisture, at the expense of your grasses & other species in a dryland pasture situation
I reckon it’s a great hay crop under irrigation, but a sh!t of a plant for permanent pasture . . .
