We aim to grow all our produce on the farm. There are, however, times
in the year when we have to buy certain vegetables from wholesale suppliers.
This for example will happen with potatoes, carrots and onions in the
winter, although we grow the crops in season and have them as fresh
produce we do not have sufficient storage to keep them throughout the
winter. When we buy vegetables in, we endeavor to ensure that we source
from the UK only and that food miles are kept to an absolute minimum.
Seeding
begins in January and continues throughout the year to give us a continuous
supply of plants. Every seed has to be hand planted. Thousands of seedlings
are raised in the poly tunnel on a heated bench, this warms the soil
and helps us to control moisture. Plants
stay in the propagation tunnel until they are big enough to go outside
and be hardened off ready for planting in the field or poly tunnels.
Poly tunnels
are extremely important within our organic system allowing us to grow
crops year round. We are able to grow three different crops a year within
each poly tunnel. In spring and early summer we use them to bring on
our early crops of new potatoes, broad beans, garlic, peas and courgettes
before our outside main crops are ready. In summer we grow the exotic
vegetables which require a consistent high humidity to crop successfully
i.e. tomatoes, cucumbers, chilies, peppers, aubergines.
In winter the poly
tunnels house our popular winter salad leaves which require protection
from frosts.
The rotation of
plants families between the tunnels is important for four main reasons.
1. To build nutrient
levels between crops. Changing crops each year allows to soil to replenish
nutrients. Leguminous plants such as peas and beans are able to fix
nitrogen from the air into the soil, making it available for the next
crop of plants.
2. Soil pests and
diseases tend to attack specific plant families, so by rotating crops
the pests' life-cycles are broken and build-up is reduced.
3. Alternating between
deep-rooted and fibrous-rooted crops improves soil structure.
4. Some crops (e.g.
potatoes and squashes) can suppress weeds, minimizing problems for following
crops.
As an organic farm we don’t use chemicals to eradicate pests and
diseases from the soil. We use best practice methods instead such as
crop rotation and select disease resistant plant varieties where possible.
We rotate crops
in the vegetable fields as we do in the poly tunnels. Each plant family
is planted in a different block each year this helps to prevent pests
and diseases building up in the soil. In the vegetable fields we grow
large scale crops such as potatoes, sweet corn, broad beans, carrots
etc.
The majority of
the work is carried out using a tractor compared to the poly tunnels
where work is carried out manually.
We protect our newly
planted crops with the use of fleeces, these prevent damage from pigeons,
deer and rabbits. Despite the use of high fences surrounding the field
the deer and rabbits always manage to break in.
We
use stale seedbeds to help eradicate weeds. Once the crop had been harvested
the ground is power harrowed using a tractor, this breaks up the soil
to a fine tilth. The weeds are allowed to establish and then are destroyed
by flame weeding. This doesn't’t disturb any weed seeds in the
soil and the new crop of vegetables can be planted on top.
This helps to reduce
the amount of weed competition our vegetable plants have to encounter.
This method however only really works for vegetables planted later on
in the summer, when the weeds have had a chance to flourish.
Not using any insecticides
in organic farming allows the predatory insects such as ladybirds to
flourish. We then rely on these to eat pests such as aphids.
Comfrey and nettles
are important plants within an organic system. They are used to make
‘tea’ which is given to the plants as a liquid fertilizer
as they contain high levels of nitrogen (N), phosphorous (P) and potassium
(K). Both plants will grow back after harvesting and can provide an
almost continuous supply of nutrient rich fertilizer.
To make this ‘tea’
we fill a water butt with as many leaves as possible then add water
and leave for six weeks to ferment. The result is a very smelly liquid
which we dilute and feed to tomatoes, aubergines and cucumbers during
fruit formation.
The flowers of comfrey
and nettles also attract Tortoiseshell, Peacock, Red Admiral and Comma
butterflies as well as ladybirds, lacewings and hover flies which are
important predatory insects eating pests such as greenfly.
Manure is another
extremely important input of organic farming. Dung from the poultry
houses is mixed with that of in-wintered sheep and stabled horses.
The manure heap
is then turned once in the summer and then again autumn to allow oxygen
to be introduced. The composting procedure heats it to 60C, breaking
down the organic matter so that our carbon: nitrogen ratio stacks in
favour of readily available nitrogen, and killing weed seeds and harmful
pathogens. Soil structure is further improved by microbiological activity,
including the activity of earthworms.
Proper composting
and utilization is essential, in that our ground is not very strong
and we grow a lot of vegetables. We spread on the vegetable field and
in the poly tunnels in the spring.
All the produce
is picked by hand when it is perfect for the shop and boxscheme, we
do not grade and vegetables on 'looks' therefore it is not uncommon
to find a misshapen carrot lurking in your box ! We have no wastage
as any uneaten vegetables are fed to the animals and staff !
