WHY HYDROPONICS?
What is hydroponics? What are the benefits of hydroponics?
Hydroponics has been practiced
by a few market gardeners and other growers since the 1940s. Since that
time it's advantages have been increasingly acknowledged and it has
grown steadily in popularity.Our principal began growing plants
hydroponically in the early 1970's and teaching hydroponic courses not
long after that. We teach it because we know it can work, and for some
situations it is the most practical and effective way of growing plants;
particularly small crops like vegetables and berries.
The advantages of hydroponics
are many; however, the disadvantages should not be overlooked when you
are deciding whether or not to set up a hydroponics system.
Advantages
1. You can grow anywhere.
Crops can be grown where no suitable soil exists or where the soil is contaminated with disease.
2. Culture is intensive.
A lot can be grown in a small
space, over a short period of time. It is also possible to grow in
multi-levels. Where transportation costs to the market are significant
(e.g. in the centre of large cities), hydroponic farms may be viable
irrespective of land values. For example, in Japan hydroponic vegetables
are grown in supermarkets in the centre of large cities. The savings on
transport costs and the benefits of having fresh produce offsets the
increased cost of space in these cities.
3. Heavy work is reduced.
Labour for tilling the soil,
cultivation, fumigation, watering and other traditional practices can be
reduced and sometimes eliminated.
4. Water is conserved.
A well-designed, properly run
hydroponic system uses less water than gardening. This is an important
advantage in areas with poor quality or limited water supplies. In
particular, hydroponics is seen to have potential benefits in
controlling water pollution in developing countries.
5. Pest and disease problems are reduced.
The need to fumigate is reduced.
Soil-borne plant diseases are more easily eradicated in many
nutriculture systems. This is particularly true in 'closed systems'
which can be totally flooded with an eradicant. The chance of soil-borne
human disease is also reduced. Though rare in developed countries, it
is possible for diseases to be transmitted from animal manures or soil
micro-organisms onto food plants grown in soil, leading to illness.
6. Weed problems are almost eliminated.
Weeds are a major problem in most soil-based systems. Weeds are almost non-existent in hydroponic setups.
7. Yields can be maximised.
Maximum yields are possible, making the system economically feasible in high density and expensive land areas.
8. Nutrients are conserved.
This can lead to a reduction in pollution of land and streams because valuable chemicals needn't be lost.
9. The environment is more easily controlled.
For example, in greenhouse
operations the light, temperature, humidity and composition of the
atmosphere can be manipulated, while in the root zone the timing and
frequency of nutrient feeding and irrigation can be readily controlled.
10. Root zone chemistry is easier to control.
Salt toxicities can be leached
out; pH can be adjusted; EC (electroconductivity) can be adjusted. Also
salts will not bind chemically to the majority of media used in
hydroponics so problems of salt build-up that may occur in soils,
particularly when highly soluble nutrients are used, are uncommon in
hydroponics.
11. New plants are easier to establish.
Transplant shock is reduced.
12. Crop rotation/fallowing is not necessary.
All areas can be used at all times - you don't need to leave a paddock for a year to fallow every so often.
The amateur horticulturist can
use hydroponic systems at home, even in high rise buildings. A
nutriculture system can be clean, light weight, and mechanised.
Disadvantages
1. Initial cost can be relatively high.
The original construction cost
per hectare is great. This may limit you to growing crops which either
have a fast turnover or give a high return.
2. Skill and knowledge are needed to operate properly.
Trained plants men must direct
the growing operation. Knowledge of how plants grow and the principles
of nutrition are important.
3. Diseases and pests can spread quickly through a system.
Introduced diseases and nematodes may be quickly spread to all beds using the same nutrient tank in a closed system.
4. Beneficial soil life is normally absent.
5. Plants react fast to both good and bad conditions.
The plants in hydroponics react
more quickly to changes in growing conditions. This means that the
hydroponic gardener needs to watch his plants more closely for changes.
6. Available plant varieties are not always ideal.
Most available plant varieties
have been developed for growth in soil and in the open. Development of
varieties which are specifically adapted to more controlled conditions
may be slow to occur.
After the Course
Every graduate will get something different from this course. This is because the course is structured to provide a degree of flexibility in what you will learn. As your learning develops, and you receive feedback in your assignments from expert tutors, you will be exploring the world of hydroponics, connecting with organisations, businesses and people; and growing different plants (your choices). Your knowledge and understanding will grow; but so will your awareness of what you might do with your new found knowledge and skills.
Some graduates will simply use this to develop a passion and build a hobby.
Many others will use this course to enhance business or career opportunities. Hydroponics is an industry that offers wide ranging possibilities. In some countries it is already a rapidly growing and well established industry, but in others it still has a long way to go.With growing urbanisation across the world, hydroponics is an intense form of food production, well suited for urban farming. In the future it may well be the best, if not only way, to provide fresh healthy food to people living in densely populated cities.
Hydroponics I is an excellent starting point; and after graduation you may either continue developing your knowledge informally, through reading, networking and hands on experience; or you may use this as a foundation to build on through further studies such as Hydroponics II and III.
