Hydroponic Farming Cost and Profit Analysis:
INTRODUCTION TO HYDROPONIC FARMING COST AND PROFIT:
The soilless farming technique which is gaining popularity these days is called hydroponic farming. This technique makes use of a water-soluble nutrient mixture for growing fruit, vegetable, or flowering plants. Generally in conventional farming technology, the soil soaks and stores the nutrients that are supplied and the plants in turn take the nutrients from the soil. But in the hydroponic method of farming plant roots get in direct contact with the water-soluble nutrient content and this helps in faster absorption and growth. The idea of hydroponic farming is believed to serve two purposes, one is it can be practiced by people to grow fresh fruits and vegetables where the soil condition is not suitable for conventional farming, second it is a solution for satisfying sustainable food requirements in urban areas where the land for conventional farming is not easily available due to other commercial business ventures. Hydroponic farming is being considered a revolution in the farming or agriculture industry because of its capability to produce surplus food. This farming technique is environment friendly as there is no much use of chemicals in the form of pesticides and insecticides. Growing plants hydroponically need an environment that can be controlled as per the requirement. This kind of controlled setup for the cultivation of crops eliminates the danger of critical warm climatic conditions in agriculture. Experts believe that greenhouse hydroponic farming is a perfect one-stop solution to all farming and food-related problems. Most of the people are showing interest to set up hydroponic systems at their homes. Even one can have commercial hydroponic farming systems for good profits. The following information describes the Hydroponic Farming Cost and Profit.
HYDROPONIC FARMING COST AND PROFIT – ADVANTAGES OF HYDROPONIC FARMING SYSTEMS
There are several advantages of hydroponic farming over other traditional methods:
- A properly well-planned design of a hydroponic system reduces the risk of water and nutrients. It is estimated that the use of land in hydroponic farming is reduced by 50% and the use of water is reduced by 90%. Therefore it is highly beneficial in areas where water is scarce and land is limited.
- The diseases caused by the soil structure in traditional agricultural techniques is absent in hydroponic farming. Also, the other aspects like tilling the soil, weeding, and maintaining sanitation are greatly reduced in hydroponic farming.
- The space required for hydroponic farming is comparatively low. The spacing between plants is also less which ensures that large production can be done in a small area. Concepts like crop rotation and other soil conservation methods can be ignored.
- The efficiency of the hydroponic system depends on the fact that plants are provided with materials that are needed for their growth. The investment is a little higher but the yield is expected to be four times higher than the conventional methods. The produce from the conventional farms is seasonal but from a hydroponic farm, it is unseasonal.
- The crops don’t need much time for harvesting. The process is much quicker when compared to other techniques.
HYDROPONIC FARMING COST AND PROFIT- PROS AND CONS OF HYDROPONIC FARMING:
- High productivity.
- More eco-friendly.
- Suitable or flexible in areas with less water and space.
- Fewer transportation facilities required.
- Monoculture is not considered a problem.
- High setup costs.
- High maintenance costs.
- The system is vulnerable to power failures, nutrient and pH imbalances, etc.
- Regular monitoring is highly essential.
- The technique needs expertise due to the involvement of complicated methods such as creating a balanced nutrient mixture etc.
To overcome the high setup and maintenance costs of the hydroponic system there has been a system developed called the ‘simplified hydroponics’. This system was launched by Ms. Peggy Bradley in the United States and was brought to India under the name of the ‘Pet Bharo’ program. The main aim of the Institute of Simplified Hydroponics was to relieve people from poverty and hunger. As it was launched in India the core purpose of the project was to empower the disadvantaged class of people by training, educating, motivating, and micro-financing them to have a sustainable means of livelihood. This method of simplified hydroponics can be initiated in a small area and gets adapted to the conditions of urban areas. This method favors the people in the following ways.
- Isolation from the soil and cultivation at a convenient level.
- Water along with low-cost substrates such as sand, rice husk and pumice, etc are used.
- Balconies, kitchen gardens, rooftops are the places that can be used for simplified hydroponics
- Recycling of water is done so that the environment doesn’t get polluted.
- Any disease or pest is controlled by natural herbal treatments. No chemicals used.
- Higher yield in less time and multiple harvests results in greater output.
- Easy-to-understand methods and less technological involvements.
- Use of recycled materials.
- Source of income to the family.
- Safe food for consumption with high biological and dietary value.
- Household food needs are achieved by fresh and nutritious food.
- Shade net (shade to sun ratio) and polythene sheet can be used to protect the plants from sun and rain respectively.
- The use of neem or garlic sprays, grease anointed plywood insect traps, etc keeps the pests, weeds, and other pathogens away.
- It is estimated that 20 square meters of land can produce 2 kg of vegetables which can cost around 110- 120 USD.
HYDROPONIC FARMING COST AND PROFIT – EQUIPMENT REQUIRED FOR HYDROPONIC FARMING:
There are various techniques or types of deploying a hydroponic farm: the wick system, water culture, ebb, and flow system, drip system, nutrient film technique, and the aeroponic technique. A basic system of hydroponics may require the following equipment which may change depending on the size of the farm and the technique being used.
- Plastic trays for the medium, nutrient solution, and the plants
- A table or elevated stand to hold the trays.
- A container to hold the nutrient mixture.
- A pumping cable or pipe can pump 500 liters per hour.
- Small pots with holes to hold the plants.
- Growing medium if necessary.
- Drainage tube.
- Timer, thermometer, and other sensors.
- Seeds or plant cuts
- Nutrient solutions.
- pH meter.
- Induction lights.
- LED grow lights.
- Beneficial insects
HYDROPONIC FARMING COST AND PROFIT – MATERIALS REQUIRED FOR HYDROPONIC FARMING:
The most important requirement of this system of farming is the nutrient solution and it is easily available at gardening centers. The nutrient solution should be a blend of important elements such as nitrogen, potassium, calcium, magnesium, etc. the nutrient solution to be used changes with the type of crop being cultivated.
Hydroponic farming can be done either with a medium or without the medium. Rock wool is the widely used medium because it is affordable and drains easily. Other mediums that can be used for farming are the clay, vermiculite, sand, gravel, and Perlite. Water circulation is not easy with sand gravel and clay as they are heavy but easily available. Perlite and vermiculite are effective.
Light is also an important factor for photosynthesis and the growth of plants. High-density discharge lights can sometimes be used during farming when adequate sunlight is not available. The use of light from various sources has different effects and is therefore used according to the plant type. Light from metal halides is used for young and green leafy plants. For fruit and flowering plants light from high-pressure sodium, lights are used.
The monitoring of the pH levels in the nutrient solution is also equally important because it specifies the acidity or alkalinity of the environment. A pH test meter is used to check the levels of the solution.
