During Wwii, farmers kept livestock alive without buying hay. They planted specific winter cover crops — and let animals harvest their own feed straight from the field. In this episode of BACKYARD CROPS, Adam Grove breaks down 9 documented wartime forage crops that: Replace winter hay Cut protein supplement costs Fix nitrogen naturally Improve soil structure Extend grazing into freezing temperatures From fodder radish and forage rape to winter rye, Austrian peas, crimson clover, and brassica systems — these crops still grow today. The real question is: why aren’t more farmers using them? 👇 Which crop would you try first? #covercrops#wintergrazing#regenerativefarming#foragecrops#homesteading#livestockfeed#soilhealth#backyardcrops#farmindependence#sustainableagriculture
Somewhere in a dusty European farmhouse in 1942, a farmer made a decision that saved his entire
herd without buying a single bale of hay. His animals grazed through frozen ground while
neighboring farms watched their livestock starve. That farmer's secret was not expensive equipment.
It was not rare seed stock. It was nine specific crops, planted in fall, grazed through winter,
that fed everything he owned for free. Feed companies know these crops exist. They have
always known. And for eight decades, they have done everything in their power to make sure
farmers never plant them again. Because a farmer who grows winter grazing is a farmer who stops
spending money on their products. Welcome to Backyard Crops. Adam Grove here. What you are
about to hear is not theory. This is documented wartime agriculture. Crops that kept European
and American livestock alive when supply chains collapsed. Crops that still grow. Crops that still
work. Crops that your feed supplier does not want on your land. If you are a livestock owner,
a homesteader, or anyone raising animals through winter, this video could change the way you farm
permanently. Drop a comment below with the word crops if you want the full planting guide.

Count it down from nine to one. Crop number nine. Hairy vetch. The nitrogen powerhouse nobody talks
about. Hairy vetch is one of the most overlooked winter legumes in North America. And that is no
accident. During the Second World War, German and Eastern European farmers planted hairy vetch as a
primary winter cover and rotational grazing. It tolerates temperatures down to minus 15 degrees
Fahrenheit once established. It grows aggressively through late fall and resumes growth earlier in
spring than almost any other legume. The protein content of hairy vetch in vegetative growth runs
between 20 and 25 percent. That matches or beats most commercial protein supplements. A farmer
running cattle through winter on hairy vetch pasture is getting protein supplement for the
cost of seed. Nothing more. But the reason the fertilizer industry wants hairy vetch forgotten
is its nitrogen fixation rate. A well-established stand fixes 80 to 200 pounds of nitrogen per acre
annually. That's a full commercial nitrogen application for the following crop, provided
completely free by the plant itself. When hairy vetch winter grazes livestock and then terminates
in spring, the decomposing biomass feeds the next crop without a bag of synthetic fertilizer being
opened. Livestock graze the vines without issue. Cattle, sheep, and goats all consume it readily.
Because it vines rather than standing upright, it survives light snow load without lodging.
You plant it in late August through mid-September. And by late October, your animals have a standing
feed supply they harvest themselves. Hairy vetch also reseeds aggressively. One establishment can
provide multiple years of volunteer stands. The seed industry profits from annual replanting.
Hairy vetch refuses to cooperate with that model.
Crop number eight. Forage rape. The forgotten British wartime feed. Forage rape is not the same
as canola. It's a livestock-specific brassica variety developed specifically for high dry matter
yield and palatability to grazing animals. British farmers kept their sheep and cattle alive through
the submarine blockades of 1940 to 1944, almost entirely on forage rape. Fields of it stretched
across Wales and Scotland during those years. One acre of forage rape produces 4,000 to 8,000 pounds
of dry matter. It establishes in 45 to 60 days from seed. Planted in August or early July, and by
September, your animals have a standing feed supply they harvest themselves. Forage rape does something
that almost no stored feed can replicate. Cold temperatures trigger a biochemical change inside
the plant. Starches convert to sugars. Protein concentration rises. A forage rape crop that was
planted in August and grazed in December is nutritionally superior to the same crop grazed
in October. The cold makes it better. Sheep and cattle graze forage rape with consistent enthusiasm,
especially after the first hard frosts, when the sweetness intensifies. The digestibility runs
between 70 and 80 percent, meaning animals extract far more usable energy from low-grade hay.
Agricultural colleges stopped teaching forage rape grazing systems after the war. It was quietly
repositioned as an oilseed crop for industrial processing. The livestock grazing application,
the one that kept British farms solvent during wartime, was removed from the curriculum. The
crop still grows. The nutritional data still holds. Most livestock farmers in America have never heard
its name. Crop number seven. Stockpile grazing multi-species mix. The system behind the crops.
Before moving into the core seven crops that formed a foundation of this method,
it is worth understanding the system that World War II farmers built around them. This is not
just about planting one crop. It is about planting multiple species together so that
grazing extends from October through April without a single bale being cut, stored, or fed by hand.
The mix works on a seasonal handoff. Early winter grazing comes from frost-sensitive crops,
radishes, rape, and turnip tops. Midwinter grazing shifts to cold hardy crops, kale,
turnip roots, and winter peas. Late winter and early spring grazing comes from regrowth crops,
winter rye, and crimson clover. Each species fills a gap the other cannot cover. Each one
contributes a different nutritional profile. The legumes fix nitrogen that feeds the grasses.
The deep-rooted brassicas break soil compaction that improves the legumes.
The system is designed so that no single failure collapses the whole feeding program.
A farm running the system in 1944 bought zero hay. Today, a farm running the system with modern seed
varieties and rotational strip grazing technique can achieve the same result. The crops are not
relics. The system is not outdated. It is simply inconvenient for the industry that replaced it
Crop number six, Austrian winter peas, the protein king of cold-season legumes.
Austrian winter peas survive conditions that destroy most other legumes. Once established,
they tolerate temperatures down to minus 10 degrees Fahrenheit. They grow actively in fall,
go semi-dormant in deep winter, and resume vigorous growth the moment temperatures lift
in late February or March. During the Second World War, northern European farmers discovered
that Austrian winter peas bridged the most dangerous gap in the feeding calendar,
the period between when hay ran out and when spring pastures began producing. That gap killed
more livestock than any other single factor in conventional winter feeding. Austrian winter peas
closed it. The protein content in vegetative growth tests between 25 and 28 percent. Animals
grazing Austrian winter peas in February and March are receiving a protein level that commercial
supplement pellets struggle to match. The cost difference is not marginal. Protein supplements
run $400 to $600 per ton. Austrian winter peas cost the price of a seed bag and nothing else.
The nitrogen fixation rate of Austrian winter peas runs between 150 and 200 pounds per acre annually,
the highest of any common cover crop. A farmer grazing peas through winter and then terminating
them in April is applying a full season of nitrogen to the following crop at zero cost.
The feed industry and fertilizer industry worked together after the war to bury this crop
specifically because it threatened both of them simultaneously. It replaced hay, it replaced
protein supplements, it replaced commercial nitrogen. One crop undermined three separate
revenue streams. It had to be forgotten, so it was. Crop number five, crimson clover. The self-receding
conspiracy. Crimson clover was one of the most widely planted crops in the American South during
wartime because it did something no annual hay could do. It gave back more than it took. Every
acre of crimson clover fixes 100 to 150 pounds of nitrogen while simultaneously producing livestock
feed at 25 to 30 percent protein in vegetative growth. That protein level rivals soybean meal.
Crimson clover grows it for the cost of seed. The southern farmers used crimson clover as a
bridge crop between summer pasture burnout and spring growth. Planted in September, it provided
grazing from November through March in mild climates, from February through April in colder regions.
Animals on crimson clover gained weight during the period when conventional hay-fed animals
lost condition. What makes crimson clover genuinely threatening to the seed industry
is its reseeding behavior. Allow a stand to flower once and seeds scatter across the field naturally.
The following fall, the crop emerges without any additional planting. A farmer who establishes
crimson clover once and manages it correctly may never purchase that seed again. The relationship
between farmer and seed company ends the moment the clover reseeds. After the war, seed companies
began promoting non-reseeding annual clovers. They bred varieties that required annual purchase.
They marketed these inferior varieties as improvements. The marketing worked. Today,
farmers who know crimson clover often do not know it reseeds because that information was
systematically excluded from product literature and agricultural extension recommendations.
The crimson clover still reseeds in every field that flowers. It still fixes nitrogen. It still
feeds livestock at protein levels that eliminates supplement purchases.

deserves to reach every livestock farmer still paying for what these crops provide for free.
Crop number four, winter rye. The regrowth crop that never stops. Winter rye is the only common
cereal grain that actively grows during conditions that make every other crop dormant. It germinates
in soil temperatures as low as 34 degrees Fahrenheit. It pushes green growth through
light snow cover. It provides fresh grazing in months when the only alternative is stored feed
purchased at peak winter prices. During the second world war, farmers on both sides of the Atlantic
used winter rye not as a grain crop but as a grazing crop, planted in September, grazed in
November, allowed to regrow, grazed again in February, and then grazed a final time in April
before the permanent pastures resumed. One planting produced three grazing events across
the hardest months of the year. A single acre managed for grazing produces 3,000 to 5,000 pounds
of dry matter across multiple harvests. But the real value of winter rye is what it costs the hay
industry. It fills every pricing window hay dealers exploit. Late November when summer pastures
are gone. January when stored hay is running low. March when winter hay has been consumed and spring
pastures have not yet started. Every one of those windows is a moment when hay prices spike and
dependent farmers pay whatever is asked. Winter rye closes every window. The farmer who grazes
winter rye in November is not calling a hay dealer in November. The farmer who strip grazes rye in
February is not pricing hay bales in February. The feed industry promoted winter rye post-war as a
soil cover, a cover crop for preventing erosion, not for feeding animals. Grazing applications were
deleted from the recommendations. Thousands of agricultural bulletins that mentioned grazing
winter rye were simply not reprinted. The crop did not disappear. The knowledge of how to use it
did. Crop number three. Brassica grazing systems. Kale. A crop that improves in winter. Forage kale
is not garden kale scaled up. It is a purpose-bred livestock variety that produces 6,000 to 10,000
pounds of dry matter per acre from a single planting. It stands through heavy snow. It feeds
livestock through January in climates most people assume require hay barns to survive winter. During
the Second World War, British farmers kept dairy herds, sheep flocks, and beef cattle alive through
four consecutive wartime winters using forage kale and forage rape as their primary feeds. When
imported grain was cut off by submarine warfare, brassica crops stood in the fields and the
livestock grazed them directly. No processing, no storage, no equipment, no transport, just animals
eating standing crops. The protein content of forage kale runs 15 to 20 percent. The stems provide
energy comparable to moderate quality grain. Animals grazing kale gain weight actively. In
controlled trials, beef cattle on forage kale gained two to three pounds daily. That is feedlot
performance from a crop that requires no feedlot. Cold temperature does to kale what it does to
forage rape. It converts starches to sugars, raises palatability, and increases energy density. A kale
crop standing in December is nutritionally superior to the same kale in September. Hay stored from
June degrades every month. Kale standing in a field improves every month through winter. These are
opposite trajectories, and the feed industry cannot afford for farmers to know it.
After the war, brassica livestock varieties were quietly removed from seed catalogs
and repositioned as human food crops. The forage varieties that fed British livestock through the
blockade became unavailable through mainstream agricultural channels. They did not disappear
entirely. Specialty seed suppliers still carry them, but they were removed from the mainstream
so thoroughly that most American livestock farmers have never encountered them.
Crop number two. Turnips. The crop that occupied farmers planted in secret. Turnips were so
effective at replacing winter hay during the second world war that occupied populations in
France and the Netherlands planted hidden patches of them at personal risk. Farmers who were forbidden
from keeping certain livestock quantities still planted turnips because they knew the crop could
sustain animals through winter on almost nothing else. One acre of fodder turnips produces 20,000
to 30,000 pounds of total feed, tops and roots combined. The leaves emerge within 60 days of
planting and contain 20 to 25 percent protein. Livestock graze the leafy tops first, gaining
weight rapidly as they consume the high protein greens. Then they move to the roots. Turnip roots
contain 8 to 10 percent natural sugar. Animals prefer them to grain when both are offered. The
sugars provide quick metabolic energy that maintain body temperature through freezing weather, a
critical function in winter livestock management that hay calories provide much less efficiently.
The grazing calendar for turnips extends from October through January in most North American
climates. That's four months of self-harvested feed from one planting. No hay to cut, no baler to run,
no wagons to load, no daily feeding labor. Open the gate and let the animals work. The equipment
industry recognized the threat immediately after the war. Turnip grazing eliminates the need for
tractors, mowers, rakes, balers, wagons, hay storage buildings and feeding equipment. A farmer switching
to turnip grazing is a farmer who stops buying machinery. The industry could not allow that shift
to become normalized, so turnips were repositioned as human salad vegetables, their forage application
quietly removed from agricultural education. The crop still produces 30,000 pounds per acre. The
roots still run 10 percent sugar. The protein in the tops still rivals most hay by a factor of two
or three. Like, share and subscribe to Backyard Crops and tell one farmer in your community that
turnips exist because someone has been making sure they don't find out on their own.
Crop number one, fodder radish, the root that buried the hay industry's biggest lie. In 1943, European
farmers facing confiscated hay supplies and winter livestock loss reached back to a crop that had
been abandoned when cheap commercial hay made it seem unnecessary. Fodder radish. And what they found
changed the feeding economics of every farm that used it. These are not salad radishes. Fodder
radishes grow to 24 inches in length and four inches in diameter. A single root weighs up to
four pounds. One acre produces 8,000 to 12,000 pounds of feed in 60 days of growth. Plant in
late August and by late October, your livestock have enough standing feed per acre to last well
into winter. The protein content of fodder radish roots runs 12 to 15 percent. Quality hay averages
8 to 10 percent. Animals grazing fodder radish are receiving meaningfully better protein than
animals eating hay. And they're harvesting it themselves, eliminating all feeding labor.
Livestock dig the roots from the soil with their mouths. The farmer does not touch the feed process.
Because fodder radish roots are 90 percent water, animals grazing them in winter require significantly
less water from external sources. In freezing weather, when water lines fail and troughs ice over,
that is not a minor benefit. It is a difference between livestock surviving a cold snap and losing
animals to dehydration. But here is the specific reason fodder radish became the feed industry's
most dangerous enemy. It improves soil while feeding livestock. The massive tap root,
sometimes penetrating 24 inches into the subsoil, fractures hardpan compaction, mines calcium and
magnesium from deep mineral layers, and deposits them at the surface where subsequent crops can
access them. When the roots die in winter, they leave channels that dramatically improve drainage,
water infiltration, and root penetration for the following season. Hay takes from soil.
Fodder radish builds it. Every acre of fodder radish reduces future fertilizer costs,
reduces tillage costs, reduces irrigation costs. The crop that feeds your animals this winter is
improving the economics of every crop you plant next year. After the war ended and commercial hay
supply chains were rebuilt, the feed industry needed fodder radish forgotten. They promoted
hay as the only viable winter feed option. They built machinery supply chains around hay production.
They ensured agricultural colleges never taught the crop that made their entire product line
unnecessary. For 80 years, it worked. The radishes still grow. They still produce 12,000 pounds per
acre in 60 days. They still feed livestock better than hay by every measurable nutritional metric.
They still improve every acre they grow on. And most livestock farmers in the country have never
seen a seed packet. What comes next? These nine crops are not historical curiosities.
They are a complete winter feeding system that requires nothing from the hay industry,
the supplement industry, the equipment industry, or the fertilizer industry.
Plant them in the right sequence, forage rape and fodder radish first, then turnips and kale,
then winter rye and Austrian winter peas, with hairy vetch and crimson clover providing nitrogen
throughout, and you have 8-10 months of active grazing from a single fall planting cycle.
The farms that used this system in 1944 bought zero hay. They spent nothing on protein supplements.
They applied no purchased nitrogen. Their animals harvested their own feed. Their soil improved
every year. Their operating costs dropped to a fraction of what neighboring hay-dependent farms
spent. Two types of farmers will exist during the next hay shortage. Those paying emergency
prices because their entire winter feeding plan depends on a supply chain they do not control.
And those walking the fence line watching their animals graze cover crops they planted for pennies
per pound the feed produced. The knowledge was buried because it was dangerous to the wrong
people. It is still dangerous to those same people today. That is why sharing this video matters.
Not because backyard crops gets views, because the farmer 3 miles down the road is still spending
money on something these crops replace completely. Subscribe to Backyard Crops,
share this video with every livestock farmer you know, drop a comment with which crop you
plan to plant first. The crops that kept wartime farm solvent still grow in the same soil,
under the same sky from the same seeds. The only thing that changes is whether farmers know to
plant them. Plant a cover crop mix this fall, graze it this winter, and never write a hay check again.
