HYDROPHONIC FARMING
" HYDROPONIC AND AEROPHONIC FARMING"
Introduction
Types of hydrophonic farming system
Nutrient Film Technique
This method is executed by growing plants under a constant flow of nutrient film at an angle for better oxygen absorption.
Deep Water Culture/ Deep Flow Technique
Also called the reservoir method, is the simplest technic where plant roots are directly in contact with the nutrient solution which is also supported by an air pump to add oxygen to the solution.
Dutch Bucket Technique
This technique is based on a constant supply of nutrient-rich water that is dripped into a series of buckets holding the plants while the excess is drained out and is again recirculated.
Root Dipping Technique
Here the plants are held above the nutrient solution with the help of support in such a manner that few of the roots are always in contact with the nutrient solution and few roots lie above the solution and act as air-absorbing roots.
Apart from these techniques, a few other ones are Wicking, Ebb and Flow Technique, Drip system, etc.
Aeroponics: Sprouting in the Air
1. Nutrient Mist
Roots in aeroponics are suspended in the air, while being sprayed periodically with a nutrient-rich solution over them. This allowed roots to receive necessary water and nutrients with allowing for greater oxygen exposure because it looks like fine droplets. Their roots are constantly exposed to the air, making the environment in aeroponics one of the highest rates of oxygenation out of any growing technique and can consequently lead to accelerated growth.
*2. High Oxygen Levels
Oxygen is essential for the work in root respiration; it, therefore, allows the plant to expand nutrients into energy. Aeroponics raises oxygen within the root zone making better health and growth rates, and efficiency in nutrient uptake higher. Many root diseases that will occur, both in soils and waterlogged conditions, are also reduced.
3. Water Efficiency
In an aeroponic system, water is utilized only in the nutrient mist, and the unabsorbed mist is usually recaptured and recycled. Therefore, aeroponics offers a very appealing option particularly for those locations where water resources are limited and provides a sustainable option to farming.
Advantages of Hydroponics and Aeroponics
1. Faster Growth Rates
Hydroponic and aeroponic systems permit faster growth of plants than conventionally farmed plants due to the immediacy of nutrient delivery and more aerated roots in general. These plants grow 25-30% faster compared to their soil-based cultivation.
Increased Yield The regulation of internal environment on pests and diseases reduces loss that is caused by climatic factors; hence, it will normally result in higher yield than other traditional modes of farming. With such precision in the delivery of nutrients and water, the possibility of the exploitation of productivities of plants is infinite.
Environmental Sustainability
Hydroponics and aeroponics lead to less herbicides and pesticides since the controlled environments reduce pest and weed pressures. In addition, the systems consume water less than that used in farming hence considered more sustainable ways of growing food.
CONCLUSION
Hydroponics and aeroponics are science-driven soilless growing techniques where crops are grown using nutrient solutions, misting and controlled environments to boost crop yield in such environments. Both advance the rate of growth and efficiency of resource utilization with promising potential for sustainable agriculture, especially in areas that can be regarded as urban or resource-poor, compared to other forms of growing techniques. They represent exciting trends toward innovative, technology-driven approaches to food production as lands and resources become increasingly constrained.
