The
soil you are working with in your organic garden is the basis for
growing healthy plants that will provide you with great yields. For your
garden beds to remain productive you have to continually find ways to
improve your soil.
Every
plant you grow removes minerals and trace elements from your soil. If
you don’t replenish your soil on a regular basis, you can expect your
plants to produce lower yields and even become less healthy and more
susceptible to pest and disease.
That’s
why we need to keep improving the soil by adding organic matter, which
includes manures, compost, mulches and other organic materials.
Below
are 15 simple ways to easily improve your soil.
COMPOSTING
is a great start. By turning organic materials into compost, you are
using a wide variety of materials and so putting back a great range of
minerals and nutrients. Compost provides humus in the soil, which
improves the soil structure and the moisture holding capacity of the
soil. Add compost as a 5 to 10cm layer (2 to 4 inches) of mulch to the
surface of your soil.
DON’T DIG
over your soil. Not only is it un-necessary to turn over, or double dig
your soil, but it can destroy both the soil texture and the
micro-organisms that are of great benefit to your soil. Besides, you
don’t need to dig. Let your earthworms do the bulk of the work. They
take nutrients from the surface and work their way deep into the soil,
making tunnels as they go, which allows both air and water to penetrate
deeply. This is a great benefit – so let the worms work the soil for
you.
MULCHING
has so many benefits; including preventing moisture loss, soil erosion
and suppressing weeds. But one of the main benefits if you’re using
organic mulches is that when they break down, they feed the soil.
That’s why you’ll need to mulch regularly – so that your mulch
continues to feed your soil.
CHECKING
YOUR PH is something you should consider. Nutrients are only available to plants
at certain pH levels. Most vegetables enjoy a pH of around 6 to 6.5,
slightly on the acidic side. If your soil is not close to this pH your
vegetable plants will not thrive as they are unable to mine the minerals
they need for optimum growth. You can buy pH testing kits from your
local nursery or hardware store. They are inexpensive and are multiple
use. A great investment in your vegetable garden.
CROP
ROTATION – Keep you soil and plants healthy by rotating your crops. This
basically means that you don’t plant the same type of plant in the
same patch of ground, one after another. Choose plants from a different
family each time you put in new plants. Otherwise the soil becomes
depleted of the nutrients that particular plant needs. The plants will
not grow as well and will become more and more susceptible to disease
and pest attack.
Growing
NITROGEN FIXERS is a great idea. The main plants that will take
nitrogen from the air and fix it to the soil are legumes – that is
peas, beans, alfalfa, clover, vetch, lentils or lupins. There are other,
but these are the most common. For best results I like to chop them to
ground level just as flowering starts. Leave the stalks on top of the
soil or throw them onto your compost heap.
LIQUID
COMPOST – Liquid fertilizers are a great pick-me-up for plants as the
nutrients are usually more available to your plants. You will also be
adding nutrients to the soil. Just put some mature compost into a
hessian bag and place it in a 20 litre (5 gallon) container. Fill with
water and allow it to steep for a week or two. If the mixture looks to
brown dilute further with more water, then pour on and around plants.
Mature
ANIMAL MANURES are a great addition to your soil. Growing
organically means that everything you include in your garden has organic
origins. So you’ll want to make sure that any manure you bring in to
your garden has not come from animals that have been given antibiotics,
hormones or any other substances that will be detrimental to the organic
nature of your vegetable garden.
Keeping
CHICKENS and some other small animals are is a great way to get some
of your work done for you. You can let chooks scratch around a patch
that you’ve finished harvesting. They’ll clean up any pests and old
plants, while scratching over your soil and adding their fertilizer as
they go.
Chicken
manure makes a wonderful addition to the compost heap – remember the
greater variety of ingredients, the more nutrients and minerals for your
soil.
WORMS
are another wonder animal for your organic garden. They take up very
little space, then turn you kitchen scraps into both worm castings and
worm juice. Take the worm
juice and mix it up with 1 part worm juice to 10 parts water. You can
spray it directly onto plant foliage or just add it to your soil. You
can do the same thing with the castings, or you can just add the
castings as a fertilizer directly onto the soil.
GROW
HERBS that are activators for
your compost heap. By having herbs such as comfrey, yarrow, dandelion,
valerian and tansy growing in your garden, you’ll always have some
close by to add to your compost heap. These herb activators will really
make your compost heap heat up faster. Each plant also has a valuable
mineral contribution, which also ends up in your soil.
HUMAN
URINE is also a great
activator for your compost heap. Urm… it’s also quite good for trees
and shrubs in the garden, providing you’re not taking antibiotics or
have any infections. To use in your compost heap, make sure it’s fresh
and diluted (about 10 -1 ratio).
BLOOD
& BONE, DYNAMIC LIFTER
and COMPLETE “D” are all
organic fertilizers that are readily available, quite inexpensive and
will greatly improve your results in your vegetable garden.
GREEN
WATER FERTILIZER: This is a
great, free way to make your own liquid fertilizer. Simply pull out any
weeds, herbs, green crops, (even grass will do). Throw all the greens
into a large bucket and fill with water . Stir it
each
day until the water looks green. Dilute 50 / 50 with more water and pour
on and around your plants. Place the mushy weeds/greens on your compost
heap.
Keep
your SOIL COVERED. When
you’ve harvested an area of your garden – even if it’s just
several plants – it’s always better to either plant new plants in
the space or cover it straight away with mulch. If you leave the soil
bear it will be open to erosion, so you will loose valuable topsoil.
By
implementing these great tips your soil will just keep on improving over
time. As your soil improves, so will the vigour of your plants and the
yields you get.
