AGRO TECH CONSULTING
MICRO IRRIGATION , SMART HOUSE FARMING
Sector has witnessing the growth and far reach of science and technology. Daily there are various new inventions to help improve the agriculture sector and get the maximum output in less time. Farmers and agriculturist are using new techniques to get benefited from it. Especially techniques in irrigation are fast catching farmer’s eye as they are need of time and one can get the surprising results by implementing it.
Classification of Greenhouses
Low cost or low technology greenhouse
Low cost greenhouse is a simple structure constructed with locally available materials such as bamboo, timber etc. The ultra violet (UV) film is used as cladding materials. Unlike conventional or hi-tech greenhouses, no specific control device for regulating environmental parameters inside the greenhouse are provided. Simple techniques are, however, adopted for increasing or decreasing the temperature and humidity. Even light intensity can be reduced by incorporating shading materials like nets. The temperature can be reduced during summer by opening the side walls. Such structure is used as rain shelter for crop cultivation. Otherwise, inside temperature is increased when all sidewalls are covered with plastic film. This type of greenhouse is mainly suitable for cold climatic zone.
Medium Cost and medium-tech greenhouse
Greenhouse users prefers to have manually or semi - automatic control arrangement owning to moderate investment. This type of greenhouse is constructed using galvanized iron (G.I) pipes. The canopy cover is attached with structure with the help of screws. Whole structure is firmly fixed with the ground to withstand the disturbance against wind. Exhaust fans with thermostat are provided to control the temperature. Evaporative cooling pads and misting arrangements are also made to maintain a favourable humidity inside the greenhouse. These system are semi-automatic.
These greenhouses are suitable for dry and composite climatic zones.
Hi-Tech or Smart greenhouse
To overcome some of the difficulties faced in medium/ or moderate tech greenhouses, a hi-tech greenhouse designed; where the entire device, controlling the environment parameters, are supported to function automatically.
1. Low cost green house USD 5 - USD 10 / per SQM
3. Medium cost greenhouse with pad and fan system USD 20- USD 30 / per SQM
4. Expensive greenhouses with fully automatic USD 30 - USD 50 / per SQM
Drip Irrigation or Water irrigation is one of the major issues among agriculturist and farmers. In areas where there is shortage of water is major problem, a new concept called “Drip irrigation”has evolved. Also known as Trickle irrigation, in this process, water slowly drips in to the soil to the roots of the tree or the plants. The complete process is implemented on farm soil by using pipes, tubes, valves, tubing and the emitters. The Dripping can be done on root layer or the soil surface in the farms. Micro spray heads are also used as devices in Drip irrigation. It sprays water in relatively small area than the water emitters. Another type of Drip irrigation called subsurface irrigation consists of driper lines or drip tape installed permanently or temporarily below the roots.
Drip irrigation system is generally installed on large scale basis. The overall system is little bit complex but after the implementation, the output is wonderful. Various components used in Drip irrigation systems are Filtration systems, Fertigation systems, Backwash controller, pipeline system, Control valves and the safety valve system, poly fittings, poly tubes and accessories, and the emitting devices. In most of the Drip irrigation system, water clogging is main problem which affects the overall system. Therefore, proper care and maintenance should be taken in filtering and pipeline works.
Sometimes, liquid fertilizers are mixed with the dripping water to provide proper treatment to the plants. One can use potable water by joining water treatment plant to the Drip irrigation system. In most cases the recycled water is used in Subsurface Drip irrigation system. If implemented properly with good design, it can help a lot in water conservation than the flood irrigation system or the water head sprinkler irrigation as it minimize the water usage. The water and fertilizers are utilized effectively and directly to the plant roots. There is no deep percolation or evaporation. It can even be implemented on uneven surface or soil texture. Also the overall system can be automated to reduce the human work load and reduce the time factor.
Thus the modern drip irrigation has become the most useful and important innovation in Agriculture sector.
Drip or trickle irrigation is a very efficient method of applying water and nutrients to crops. For many crops, the conversion from sprinkler to drip irrigation can reduce water use by 50 percent.
Poly House & Net house Farming
A high-tech mode of vegetable cultivation, to increase the productivity of farm produce.
Smarthouse / polyhouses are in high tech farming category; the electronic sensors provide early warning systems so that vegetables can be cultivated without the risk of pest attacks or vagaries of climate change.
A wide variety of vegetables that come to our kitchens today - right from common vegetables like cucumber, pumpkin, brinjal, cowpea and cabbage to capsicum, cauliflower, broccoli, spinach and lettuce - can be cultivated using this system. The user-friendly system helps farmers plan irrigation and fertigation (application of fertilizers) based on environmental and soil conditions.
The system has many unique features like control panel, sensors, solenoid valves and exhaust fans. The control panel monitors different parameters like soil moisture, soil nutrients, atmospheric temperature and wind speed using sensors and informs the farmer through a display unit and takes corrective measures.Based on data collected from the field, the controller device can automatically operate pumps and valves.
The device could receive alerts of important field parameters or alarm conditions even when the person is away from the farm in the form of pre-programmed SMS in his mobile phone. The alarms can also be configured to give alerts through LED flashes or hooters as well.
Type of Poly Houses
Naturally ventilated poly house
These polyhouses does not have any environmental control system except for the provision of adequate ventilation and fogger system to prevent basically the damage from weather aberrations and other natural agents..
Environmental controlled poly house
This type of poly house helps to extend the growing season or permits off-season production by way of controlling light, temperature, humidity, carbon-dioxide level and nature of root medium.
Shade houses are used for the production of plants in warm climates or during summer months. Nursery men use these structures for the growth of hydrangeas and azaleas during the summer months. Apart from nursery, flowers and foliages which require shade can also be grown in shade houses. E.g. Orchids, These shade structures make excellent holding areas for field-grown stock while it is being prepared for shipping to retail outlets. Shade houses are most often constructed as a pole-supported structure and covered with either lath (lath houses) or polypropylene shade fabric. Polypropylene shade nets with various percentages of ventilations are used. Black, green, and white coloured nets are used, while black colours are the most preferred as it retains heat outside.
As compared to traditional farming , a farmer can earn a 5 times by adopting smart polyhouse technologies.

Farming without soil !
We're so used to plants growing in fields and gardens that we find anything else completely extraordinary. But it's true. Not only will plants grow without soil, they often grow a lot better with their roots in water or very moist air instead. Growing plants without soil is known as hydroponics. It might sound weird, but many of the foods we eat—including tomatoes on the vine—are already grown hydroponically. Let's take a closer look at hydroponics and find out how it works!
Plants grow through a process called photosynthesis, in which they use sunlight and a chemical inside their leaves called chlorophyll to convert carbon dioxide (a harmless gas in the air) and water into glucose (a type of sugar) and oxygen. Write that out chemically and you get this equation:
6CO2 + 6H2O → C6H12O6 + 6O2
There's no mention of "soil" anywhere in there—and that's all the proof you need that plants can grow without it. What they do need is water and nutrients, both easily obtained from soil. But if they can get these things somewhere else—say, by standing with their roots in a nutrient-rich solution—they can do without soil altogether. That's the basic principle behind hydroponics. In theory, the word "hydroponics" means growing plants in water (from two Greek words meaning "water" and "toil"), but because you can grow plants without actually standing them in water, most people define the word to mean growing plants without using soil.
There seem to be many advantages in growing without soil. Some hydroponic growers have found they get yields many times greater when they switch from conventional methods. Because hydroponically grown plants dip their roots directly into nutrient-rich solutions, they get what they need much more easily than plants growing in soil, so they need much smaller root systems and can divert more energy into leaf and stem growth. With smaller roots, you can grow more plants in the same area and get more yield from the same amount of ground (which is particularly good news if you're growing in a limited area like a greenhouse or on a balcony or window-ledge inside).
Hydroponic plants also grow faster. Many pests are carried in soil, so doing without it generally gives you a more hygienic growing system with fewer problems of disease. Since hydroponics is ideal for indoor growing, you can use it to grow plants all year round. Automated systems controlled by timers and computers make the whole thing a breeze.
