Can farming give back more than it takes?
0:08
Every landscape tells a story
0:11
and here at the Waitrose Farm on Leckford Estate,
0:14
the story is about how we farm the land,
0:17
and how that land can recover.
0:20
Waitrose is the only UK supermarket to own a farm
0:24
and support farmers to transition to regenerative practices by 2030.
0:30
It's a term we are hearing more and more.
0:32
But what does it really mean in practice?
0:35
Can you explain us what is regenerative agriculture?
0:39
Just to keep it really simple,
0:40
it's about soil and nature.
0:42
A lot of people just don't realize that soil is a living thing,
0:46
and of course, a living thing needs to be looked after.
0:48
A teaspoon of soil potentially
0:51
has as many life forms in it as people on the planet.
0:55
And here at the Waitrose Farm,
0:58
they have been farming regeneratively
0:59
since 2020 and they are still learning.
1:03
We still lose in the UK somewhere between
1:05
two and three million tonnes of topsoil a year,
1:08
but it can take, depending on the soil type,
1:10
400 to 1000 years to build a centimetre of soil.
1:13
I mean, that's extraordinary.
1:14
So we've got to look after this precious asset.
1:18
If I can increase the soil organic matter in this field by one [JN1]percent,
1:21
that's worth probably
1:23
about 250,000 litres of water per hectare,
1:26
which in a dry summer is probably an extra
1:28
two weeks of the crops’ ability to grow.
1:33
One of the most important parts of the system here
1:36
is something called a herbal ley,
1:38
a field left to grow a rich mix of plants.
1:42
It's part of a 12-year rotation on the Waitrose Farm.
1:46
Peppery.
1:47
Hmm.
1:48
So herbal ley,
1:50
it's made up of 18 different plants.
1:53
So you've got legumes.
1:54
That'll be probably six legumes, six herbs, six grasses.
1:58
So that's why it's called a herbal ley, because of the mix.
2:01
And cows obviously produce their own
2:03
Manure, which can be returned to the soil.
2:06
With the clover in the mix, you're mitigating
2:09
the need to put artificial fertilisers on.
2:13
Last summer, very dry summer,
2:15
lots of people struggled, and farmers were having to feed
2:19
winter food to the cows during the summer.
2:21
Right.
2:21
But we found that with these herbs,
2:24
these stay green all year.
2:26
And these cows were out
2:27
for the whole summer
2:28
without needing any additional food.
2:29
Hey, ladies!
2:31
What’s up?
2:32
Oh my God.
2:33
You’re looking beautiful today.
2:38
It's more mimicking the way the buffalo
2:40
moved across America.
2:41
They're not sticking to one spot.
2:43
They're not really treading
2:44
on the same point again and again.
2:46
Because that's where you get your compaction.
2:48
Yeah, you don't want compaction.
2:51
So this is an oilseed rape plant.
2:53
Okay!
2:54
So this has come from one seed that was planted.
2:57
That is crazy.
2:58
And this one seed has then become this plant.
3:01
With all of these branches you can see
3:03
that that is a healthy strong plant.
3:06
The seeds are then cold pressed [into] rapeseed oil.
3:08
The waste is the husk of the seed.
3:11
We can give it to the cows.
3:12
So all of this is grown on site and it's then used on site.
3:15
Nothing is wasted.
3:16
100%?
3:17
Yeah.
3:17
Amazing.
3:19
Every time we fill a basket,
3:20
we're casting a vote for how the land is farmed.
3:24
Emily is a soil scientist at Cranfield University,
3:27
and spending time with the research
3:29
changed the way she thinks about food.
3:32
It really just blew my mind
3:34
that we are all reliant on the top
3:36
few centimetres of the world,
3:38
and we're losing it at an alarming rate.
3:41
It's so important that we manage it well
3:42
and protect it.
3:44
When I go to the shops,
3:46
I try to look for crops that are grown
3:49
in the UK, where I live,
3:50
and also try and eat a bit more seasonally.
3:53
You might also see some products coming through
3:55
with the word regenerative on.
3:57
What it means is that farm or farmer,
3:59
are incorporating practices
4:01
to be able to increase their soil health.
4:05
Seeing regenerative farming
4:06
at the Waitrose Farm on Leckford Estate
4:09
reminded me that the health of the land
4:12
begins with the soil,
4:14
whether it's a field in England
4:16
or my land back in Portugal.
4:18
The principle is the same.
4:20
When we care for the land, the land can care for us.
4:25
Healthy soil grows more than food.
4:27
It grows the future. [JN1]Says 1% in the video so can we swap to this written version pls?
