Gardening A Way Towards Sustainable Lifestyle

Before getting into the deep knowledge first we should understand what is gardening and why do we need it!

Gardening is the practice which we do to grow and cultivate various kind of plants such as ornamental plants, flowers, foliage, root vegetable, fruits and herbs for consumption or decoration purposes. Gardening ranges in scale from fruit orchards, to long boulevard plantings with one or more different types of shrubs, trees, and herbaceous plants, to residential back gardens including lawns and foundation plantings, and to container gardens grown inside or outside. Gardening may be very specialized, with only one type of plant grown, or involve a variety of plants in mixed plantings. It involves an active participation in the growing of plants, and tends to be labour-intensive, which differentiates it from farming or forestry.

Sustainable Gardening-

Now-a-days people are quite aware about using organic practices where it doesn’t harm mother nature by using harsh chemicals in the soils which harms the soil microbial activity. Mother nature have given us a lot hence by practicing sustainable gardening we can give back to mother nature by avoiding inorganic practices and adopt organic practices to sustain the nature. Sustainability is not a onetime practice it is basically a lifestyle which in long terms serves it purpose with both wealth & cost savings.

Gardening tools and its importance-

We all love to do gardening but it comes with a hefty job of maintaining it time to time otherwise all the hard works goes to vain.

The importance of using right gardening tools –

At some point in our lives we wonder about having our own garden like “Wow, wouldn’t it be great to have our own garden. Perhaps one person dreams of growing his own vegetable. Perhaps some dreams of creating lush green flower garden. Whatever the reason you want to start your own gardening project, for which a person needs a right type of gardening equipment.

Gardening is a great hobby and occupation. The more you learn about gardening the more you will want to purchase the tools being sold at plant store or gardening department. Before you go all out and purchase every tool you come across, start with the basics. As you get more experience with gardening you will figure out which gardening tools you need and which are only luxuries.

General:

The world population will be 9 billion by 2050, there is a continuous need to increase food production and buffer stocks. In this scenario, countries around the world, especially developing countries where the pervasiveness of hunger and food scarcity is more acute, are resorting to various counter strategies to meet the growing demand and to avert food insecurity and famine. Over the recent years there has been growing interest to strengthen and intensify local food production in order to mitigate the adverse effect of global food shocks and food price volatilities. Consequently, there is much attention towards home gardens as a strategy to enhance household food security and nutrition. Home gardens are an integral part of local food systems and the agricultural landscape of developing countries all over the world and have endured the test of time.

 About home gardens:

Home gardens are found in both rural and urban areas in predominantly small-scale subsistence agricultural systems. The very beginning of modern agriculture can be dated back to subsistence production systems that began in small garden plots around the household. These gardens have persistently endured the test of time and continue to play an important role in providing food and income for the family. Home gardens are defined in multiple ways highlighting various aspects based on the context or emphasis and objectives of the research.

Definition of home gardening:

The household garden is a small-scale production system supplying plant and animal consumption and utilitarian items either not obtainable, affordable, or readily available through retail markets, field cultivation, hunting, gathering, fishing, and wage earning.

Household gardens tend to be located close to dwelling for security, convenience, and special care. They occupy land marginal to field production and labor marginal to major household economic activities. Featuring ecologically adapted and complementary species, household gardens are marked by low capital input and simple technology.

Experiences of home gardens from developing countries: 

Home gardens have been an integral part of local food systems in developing countries around the world. Many studies provide

descriptive evidence and analysis of home gardens in developing

countries in Asia, Africa, and Latin America and pinpoint their numerous benefits to communities and families. They encapsulate perpetual small-scaled subsistence agricultural systems established by the households to obtain and supplement the food requirements of the family. Home gardens are mainly intended to grow and produce food items for family consumption, but they can be diversified to produce outputs that have multiple uses including indigenous medicine and home remedies for certain illnesses, kindling and alternative fuel

source, manure, building material, and animal feed. Home gardens as a 'place for innovation' with the potential to improve the livelihood of peri-urban and rural communities.

Social benefits:

Enhancing food and nutritional security:

Reviews of studies from various countries reveal that the degree and combination socio-cultural impacts on societies engaged in home gardening vary across the board. Multiple social benefits of home gardens include enhancing food and nutritional security in many socio-economic and political situations, improving family health and human capacity, empowering women, promoting social justice and equity, and preserving indigenous knowledge and culture

Improving health:

Plants are an important source of medicine for humans and livestock and are used as biological pesticides to protect crops from diseases and pest infestations. Herbs and medicinal plants are grown in home gardens all over the world, and in developing countries nearly 80% of the people use them to treat various illnesses, diseases, and also to improve their health conditions

Uplifting the status of women:

In many cultures, women play an important role in food production but at times their worth is somewhat undermined. They are also active in home gardening, though their involvement in the home garden tends to be determined by socio-cultural norms. In most scenarios women’s contribution to household food production is immense, but this does not imply that home gardening is predominantly a female activity. Women’s participation and responsibilities in home gardening varies across cultures, including land preparation, planting, weeding, harvesting, and marketing

How the proper gardening equipment and watering helps flourish home gardens:

Now a day’s people are getting more aware about the modern gardening

tools and its usage in home gardening.

The right amount of water in home gardens can produce more crop and it also saves your time. Where the concern for water saving technology is also getting noticed now it’s the time to use which is best for everyone.

As we know in recent times where due to the pandemic the people got stuck at home and working all days, home gardening brings a wave of positivity which helps people to live a healthy and balanced life.

INTRODUCTION

Currently hydroponic cultivation is gaining popularity all over the world because of efficient resources management and quality food production. Soil based agriculture is now facing various challenges such as urbanization, natural disaster, climate change, indiscriminate use of chemicals and pesticides which is depleting the land fertility. Leading countries in hydroponic technology are Netherland, Australia, France, England, Israel, Canada and USA.

Hydroponics operations; benefits and limitations; performance of different crops like tomato, cucumber, pepper and leafy greens and water conservation by this technique. Several benefits of this technique are less growing time of crops than conventional growing; round the year production; minimal disease and pest incidence and weeding, spraying, watering etc can be eliminated. Commercially NFT technique has been used throughout the world for successful production  of leafy as well as other vegetables with 70 to 90% savings of water. For successful implementation of commercial hydroponic technology, it is important to develop low cost techniques which are easy to operate and maintain; requires less labour and lower overall setup and operational cost.

Hydroponics is a technique of growing plants in nutrient solutions with or without the use of an inert medium such as gravel, vermiculite, rockwool, peat moss, saw dust, coir dust, coconut fibre, etc. to provide mechanical support. Most hydroponic systems operate automatically to control the amount of water, nutrients and photoperiod based on the requirements of different plants.

In the present scenario, soil less cultivation might be commenced successfully and considered as alternative option for growing healthy food plants, crops or vegetables. Agriculture without soil includes hydro agriculture (Hydroponics), aqua agriculture (Aquaponics) and aerobic agriculture (Aeroponics) as well as substrate culture. Among these hydroponics techniques is gaining popularity because of its efficient management of resources and food production.

 HYDROPONIC STRUCTURES AND THEIR OPERATION

 Hydroponic system are customized and modified according to recycling and reuse of nutrient solution and supporting media. Commonly used systems are wick, drip, ebb-flow, deep water culture and nutrient film technique (NFT) which are described below :

 Wick System

This is simplest hydroponic system requiring no electricity, pump and aerators. Plants are placed in an absorbent medium like coco coir, vermiculite, perlite with a nylonwickrunning from plant roots into a reservoir of nutrient solution. Water or nutrient solution supplied to plants through capillary action. This system works well for small plants, herbs and spice and doesn’t work effectively that needs lot of water

 Ebb and Flow system

This is first commercial hydroponic system which works on the principle of flood and drain. Nutrient solution and water from reservoir flooded through a water pump to grow bed until it reaches a certain level and stay there for certain period of time so that it provide nutrients and moisture to plants. Besides, it is possible to grow different kinds of crops but the problem of root rot, algae and mold is very common therefore, somemodified system with filtration unit is required.

  Drip system

The drip hydroponic system is widely used method among both  home and commercial growers. Water or nutrient solution from the reservoir is provided to individual plant roots in appropriate proportion with the help of pump. Plants  are usually placed in moderately absorbent growing medium so that the nutrient solution drips slowly. Various crops can be grown systematically with more conservation of water.

Deep water culture system

In deep water culture, roots of plants are suspended in nutrient rich water and air is provided directly to the roots by an air stone. Hydroponics buckets system is classical example of this system. Plants are placed in net pots and  roots are suspended in  nutrient solution where they grow quickly in a large mass. It is mandatory to monitor the oxygen and nutrient concentrations, salinity and pH as algae and molds can grow rapidly in the reservoir. This system work well for larger plants that produce fruits especially cucumber and tomato, grow well in this system.

Nutrient Film Technique (NFT) system

Automatic filtration vs. Manual filtration

If you are having a doubt to choose between Automatic filtration and Manual Filtration, In this article you would be able to make the right choice by knowing the difference between both the systems.

Let’s talk about the self-cleaning process of these systems-

Automatic- The self-cleaning process in Automatic filtration does not requires and operating personnel, which reduces the time and physical efforts of the person. The European technology used in Azud filtration system help to run these system in a long way, while giving the maximum satisfactory results.

Manuals- Continuous inspection work is required to know the state of the filter medium. Without precise control of the time and frequency of intervention required or of the pressure differential values ​​at which each cleaning is carried out. Cleaning work totally dependent on the availability of the operating personnel.

Effectiveness: Cleaning the filter medium-

Automatic:

Automatic filters require, for a totally effective cleaning, that the installation have an operating pressure value equal to or greater than a minimum required value. This information must be provided by the manufacturers so that it can be used during the design phase, since this value is specific for each selected filter model.

Manuals: 

The effectiveness of cleaning the filter medium is conditioned by the qualification and availability of time and means of the operating personnel, with no guarantees that this will be carried out effectively.

Frequency: Filter element cleaning-

Automatic: 

The frequency of cleaning is directly conditioned by the quality of the available water, by the characteristics of the chosen filter medium and by the selected sizing criterion that determines the unit flow assigned per unit of filter surface.

Manuals: 

The frequency of cleaning is determined by the same exposure and design conditions as in the automatic filters and, in addition, by the effectiveness achieved in each of the cleaning carried out by the operating personnel. A lack of effectiveness in manual cleaning of the filter element reduces its filtering capacity and therefore generates a higher frequency of intervention.

Differential pressure-

Differential pressure measurement is the difference in pressure between two points in a system.  For filtration applications, the upstream side [A] is positioned before the filter [B], whereas the downstream side [C] is after the filter. A differential pressure sensor can be used to monitor the cleanliness of a filter in either liquid or gas applications.

Automatic: 

The pressure differential values ​​that are reached during the filtration phase, foreseen in the design phase, are always within a range with known maximum values, usually [0.1-0.5] bar. The minimum value is determined by the differential value for the circulating flow with the filters completely clean. The maximum threshold is determined by the value set for activating the self-cleaning process. Under these operating conditions, we can affirm that:

The hydraulic interaction, generated between the supply source of the hydraulic requirements and the filtration equipment, does not compromise the nominal operating conditions of each of the irrigation sectors that make up the field installation.

The values ​​of uniformity of application of the irrigation water determined in the design phase remain stable over time, thanks to the narrow width of the maximum differential interval that can be reached.

The energy consumption associated with the filtration process is very low, directly related to the moderate values ​​of the mean and absolute pressure differentials.

Manual: 

The pressure differential values ​​that are reached during the filtration phase are within an interval with its two extremes conditioned, among other factors, by the effectiveness with which the manual cleaning of the filter element is carried out and the value maximum pressure that can be reached in the system, specific to the pumping equipment and inspection frequency. Under these operating conditions, we can affirm that:

The supply of the hydraulic requirements demanded by the field installation are directly conditioned by the pressure differential values ​​existing at each moment. High pressure differential values ​​cause an increase in the pressure values ​​upstream of the filter and a reduction in the supply pressure values ​​to the field installation, and therefore the flow rate of the filtered water supply.

The temporal uniformity of application of the irrigation water is compromised and is dependent on carrying out the cleaning tasks of the filter medium at the precise moment.

The energy consumption associated with the filtration process is variable in time and can be very high, directly related to the temporal variations and amplitude of the values ​​of the mean and absolute pressure differentials.

Reaching high pressure differentials can damage certain types of filter media. On the other hand, manual cleaning of the filter medium can also damage it if not done properly.

Hydroponics is a type of horticulture and a subset of hydroculture, which is a method of growing plants, usually crops, without soil, by using mineral nutrient solutions in an aqueous solvent. Terrestrial plants may be grown with only their roots exposed to the nutritious liquid, or, in addition, the roots may be physically supported by an inert medium such as perlite, gravel, or other substrates.

In today times where getting water for crop irrigation is so crucial, Hydroponics provides the solution by using minimal water for crop cultivation.

For eg: To grow 1 Kilogram of tomatoes using intensive farming requires 400 litres of water using hydroponics. Since it takes much less water grow produce, it could be possible in the future for providers in harsh environments with little accessible water to grow their own food.

 Why do we choose Hydroponics?

·         In the present time the water is the essential source for which we are getting less access day by day. As per the given situation hydroponics has given us the choice to grow our own crop with minimal water wastage.

·         In market the vegetable crop is highly perishable hence the cost of the crop fluctuate a lot. While analyzing the demand in certain area, Hydroponics provides the fast growth of the crop, hence the farmer can sell his/her crop before the season where they can get the high price.

·         More and more urban population if inclined towards the organic crop usage, hydroponics system gives us the opportunity to grow the crop organically with minimal pest and disease to the crop. Which gives the opportunity to the farmer to grow the crop organically, hence high quality crop with high income.

·         Less water usage is the one of the highest advantage of the hydroponics system, we do not require to waste a high amount of water to grow the crop, even the areas which have low access to the water and irrigation to the crop, in those areas hydroponics can be a very promising system which can be used by today’s farmers.

·         The growth rate of the crop would be 2X high by using hydroponics system. As we know in any season demand of off seasonal crop gets high, by using hydroponics the farmers can grow the crop before the season starts this would give the opportunity to farmer to sell their crop at a high rate.

·         One of the main problem we face in soil crop cultivation is weed, which takes up the nutrient of the crop and hamper the main crop growth, while using hydroponics this problem can be eliminated because the weed formation does not occurs in hydroponics module which will help to grow the crop by using all effective nutrient.
