Offers a Healthy Alternative to Organics Organic food is not a fad, it’s a phenomenon that’s here to stay. The principle goal of organic agriculture is to minimize soil degradation and erosion, decrease pollution while optimizing biological productivity in harmony with the environment. According to the Canadian General Standards Board, organically labeled foods do not represent specific claims to the health, safety, and/or nutrition of such foods. There is no disputing that organically grown produce is better for the environment and tastes better than soil grown crops that use polluting, chemical fertilizers, herbicides and systemic pesticides. Hydroponic culture incorporates a controlled, ecologically sound environment. Soluble nutrient formulas are re-circulated and used by plant’s roots eliminating environmental waste. Plants tend to be healthier in a hydroponic system than those grown in soil, making them more pest resistant. Biological control agents, such as the introduction of predator insects prior to any infestation of destructive bugs, are used as preventative measures. Harmful herbicides are simply not required as there are no weeds in a hydroponic garden! Over 40% of greenhouses in Canada employ hydroponics in their food production and this figure is rising annually. The limited crop failure and high yields reported by hydroponic producers keeps the cost to the end user down. Organic farms must incorporate time consuming, labor intensive weed controls, as synthetic herbicides are prohibited. Expensive alternatives to pest control such as companion planting of non-profit, bug deterring plants is also a factor. To be certified organic, farmers must pay an annual fee of approximately $1,000.00 and undergo a yearly on-farm inspection by the Organic Crop Improvement Association to ensure they adhere to strict organic standards. All this is factored into the price of organic produce available in the supermarkets. Hydroponics is a clean, safe horticulture technique that offers an economic, healthy alternative to organic soil gardening. A study comparing soil versus hydroponically grown tomatoes and sweet peppers was conducted by Plant Research Technologies Incorporated in San Jose, California. Their research found a dramatic increase in vitamins and minerals in hydroponics. In some cases up to 50% higher in vitamin content. Plants use inorganic minerals for nutrition, whether grown in the field or in
a container. Complex interactions involving weathering of rock minerals,
decaying organic matter, bacterial decay of animals, and microbes take place to
form inorganic minerals in soil. Roots absorb mineral nutrients as ions in soil
water. Plant nutrition is a term that takes into account the interrelationships of
mineral elements in the soil or soilless solution as well as their role in plant
growth. The interrelationship involves a complex balance of mineral elements
essential and beneficial for optimum plant growth. In prepared hydroponic
nutrients minerals are designated inorganic, however they are natural. Through ash-residue analysis, scientists have been able to determine a
plant’s exact requirements at both the vegetative and flowering stages.
Researchers isolated the ideal parts per million (ppm) of each individual trace
element required. In hydroponics, optimum growth is achieved through natural
mineral supplements. Plants are fed exactly what they require, thus eliminating
waste. Should a problem occur in a hydroponic garden, mineral imbalances are
easily identified and adjusted if necessary. There are many prepared organic hydroponic nutrients and a wealth of recipes
for homemade mixtures on the market today. These have been made available
because of a huge consumer demand. However, it has yet to be determined if there
is any real benefit to incorporating organics with hydroponics. |
