Many of the greenhouse operations use soluble fertilizers by irrigation in the roots of plants. This method is called Fertigation. The solution of fertilizer is measured and injected into the irrigation line. The water supplies the fertilizer to the plants. Greenhouse irrigation is becoming very popular in horticultural and agricultural sectors.

It decreases the waste material and the impact on the environment. This is adopted by many farmers. There are many important benefits. They are as follows:

• The process of fertigation fertilizes the crops by using a hydroponic system or drip tape. It eliminates the use of the foliar Fertigation system delivers nutrients to the roots directly.
• Crop growers install fertigation for greenhouses to decrease the use of water.
• It also decreases the wastage of nutrients in large operations.
• It reduces the application and rate of fertilizers. At this moment, increases the impact of fertilizer used.
• It eliminates the need to water the crops in the evening. When you use the foliar spray, water gets collected on the plant surface. If the water is allowed to remain overnight, it can lead to the formation of fungus.
• The techniques of fertigation reduce the cost of fertilizers and variations in the soil.

Methods of Fertigation

There are two main methods of fertigation. They are proportional fertigation application and quantitative fertigation method.

• Proportional fertigation application method- The rate of injection is directly proportional to the rate of discharge of water. This is a very simple method. It is an efficient irrigation system where the demand for water and nutrients is high.
• Quantitative fertigation- It is used in the open field where production is very high. It uses the bypass tank. The nutrient solution is measured in accurate quantity and then applied to each of the blocks. Fertilizer Injection Control and distribution is very accurate.

Fertigation tips

• You must use the fertilizer that is soluble in water. It is necessary to avoid blocking.
• You must clean the system after application of nutrients. It helps to keep the line clear and clean of debris. It prevents the system from clogging and corrosion.
• Every plant has different requirement of nutrients. So, apply the nutrients according to the requirement.
• As a crop grower, you must compare readings against nutritional values. You are advised to adjust the values according to the type of soil and life cycle.
• Take care not to water the plant in excess. Nutrients like nitrogen might get leech into soil due to excess water.
• Take care of the length of the pipe and uniformity in the nutrient flow.
• To check the functioning of the system, you must measure the electrical conductivity of the solution.
• The method of fertigation depends on irrigation type and size of the greenhouse. You can also dissolve fertilizer in the container. Also, a hose injector can be used to water the plants manually.

The process of fertigation makes the process of crop production very simple and easy. It includes less labor and money. You must be aware of the nutrient requirement of every crop.

Lawns- An Unhealthy Obsession?

We love our green lawns, don’t we? In the US, we have over 63,000 square miles of lawn. That’s about the size of Texas! We spend more than $40 billion each year on lawncare in North America. We take pride in a green, manicured lawn. It’s sometimes a requirement to keep your grass green depending on Homeowners Association rules. But what if this obsession was doing harm to our families and pets? What if it’s causing some severe environmental problems in our lakes and rivers? Should we continue to fertilize our lawns with synthetic nitrogen? Are there any alternatives if I want to keep up a healthy green yard? Keep reading to learn more.

Are We Bringing Toxins into the Home?

Probably the biggest reason you should ditch your chemical lawn is the unhealthy toxins. To delay the release of fertilizer, manufacturers add things like formaldehyde and synthetic polymers. These polymers are suspected endocrine disruptors. So, they might cause hormonal problems in humans. We don’t really know. And sure, the chemicals are all going outside the home. I get that. But how many times do your kids play barefoot outside? What about the dog and the cat? On top of that, you’re probably tracking that stuff into the house on your shoes. Makes you think twice about that green lawn, huh?

What’s Happening to our Lakes and Rivers?

In addition to the possible health risks, our addiction to lawns has harmed our waterways. All the nitrates from chemical lawns runs downhill. It eventually finds its way into lakes, rivers, and streams. This causes algae blooms and reproductive health problems for fish and other aquatic species. In fact, there’s an area in the Gulf of Mexico referred to as the “dead zone”. It’s an area where chemical fertilizer pollution has caused a massive die-off of fish and other species. At one point this area was larger than the state of Connecticut!  

How Can I Keep My Lawn and Avoid Toxins?

Remember how I mentioned that there are alternatives? You can keep your healthy green turf while avoiding toxic byproducts. Just switch to organic lawncare products. You’ll avoid the chemicals and you might actually have a healthier lawn. There are even some possible cost savings from switching to organic lawncare. Yes, I said cost savings! Sometimes we hear organic and immediately think “expensive”. But that’s not always the case. If you build up healthy soil, your grass has access to more of the minerals that are already present. This can save you money on both fertilizer and water in the long-run. So, consider making this small change for both your health and for the environment. You’ll be glad you did!

Landscape designs in Sydney keep changing with landscape designers becoming more creative with each new home. New trendy designs with every new home developed has seen the growth of Sydney landscapers in the last year.

A landscape designer in Sydney can set a house on site, connect it with the environment and create a welcoming exterior to the home.

They make the most of your outdoor space bringing your ideas to life. Landscape designers can design and plan gardens, swimming pools, paving and decking and many more. In Sydney more homes are becoming a creative haven, going with the trends in landscape designs.

Backyards designs 

It’s no longer old fashioned to have your own organic kitchen garden, it’s become one of the trend setting landscape designs. To achieve this you need a landscape designer to design easy garden features easy to maintain and sustainable. For easy maintenance, Sydney landscapers are using removable features for easy repair and replacement.

Indoor adventures 

It is rare to find vines creep the wall of a well structured lounge but it’s a growing landscape trend in Sydney. With more new homes in Sydney turning their courtyards and backyards into outdoor lounges and dining areas. With less foliage the outdoor space is easy to maintain, Sydney landscapers spruce it up with outdoor fireplaces and lighting fixtures. Trendy furniture set outside with proper fabrics that are waterproof fade resistant creates a delightful living space.

New homes in Sydney are considering popular economic and environmental reasons with less maintenance in time and effort. Landscape designers use paving of lawns which are easily replaced are of low cost and easily maintained.

Vertical gardens 

Smaller spaces can be lit with vertical gardens, to either cover unsightly brickwork or concrete walls. It can conveniently be set up and easy to maintain, you can look for something simple such as out creepers and hanging baskets. Alternatively landscape designers can use modular systems typically boast of complex hydroponics which takes the fuss out of maintenance.

Landscape designs in Sydney continue to change with landscapers going the extra mile to make spaces attractive. If you are still looking for amazing landscape designs for your home these new trends will pique your idea and perfect it in your garden.

Water, a vital resource for survival of all living organisms, is also one of the most misused and abused of our natural resources. So much so that several parts of the world are facing acute water shortage and an uncertain future. In fact, water is famously quoted to be the ‘new oil.’

Water Supply and Demand Threats

Threats have increased at both supply and demand fronts. One of the major supply side threats is that we are withdrawing freshwater from surface water sources faster than they can be replenished. Another issue is the degradation of water, making it unsuitable to fulfil human needs. The increasing global population is a major demand side issue, the other being a substantial part of the population concentrated in regions that fail to keep up with demand levels. Lack of laws and proper regulation to monitor usage and consumption by individuals and industries are also creating an unhealthy balance in water distribution.

It is widely known yet often ignored, that if we continue to abuse water resources, our survival on the planet is at risk. Lakes are disappearing, the number of drought-prone regions around the world is increasing, and more and more countries are becoming water insecure. It is time that we become more conscious about these valuable resources to avert an irreversible water crisis for our future. Some individuals and companies have taken up the challenge and devised innovative solutions to beat the water crisis.

Solar Powered Water Purification System

Hot and dry climate are most prone to water shortages and whatever little water they do receive is deemed unfit for drinking. This drove a 16 year old American schoolgirl to use solar energy for  purifying water. She exposed titanium dioxide and zinc oxide to the sun’s UV radiation which produced a photo catalytic composite that purifies the water. This technology is safe, clean, green and cost effective. It is adopted widely by regions in USA experiencing hot and arid climates.

Lifesaver Bottle

The lifesaver bottle used widely by welfare aid companies, hikers and army contingents was invented to solve the problem of dirty drinking water.  The lifesaver bottle uses a narrow pump which forces water through a filter of about 15-nanometres, killing all bacteria and viruses in the process. It has been a successful, cost-effective way of making available water suitable for daily consumption saving the financial and environmental struggle of delivering water to the remotest of places. Following the success of the lifesaver bottle, water treatment companies are also coming up with similar inventions on a grander scale to improve the quality of drinking water.

Leak Monitoring System

Utility companies are now using leak monitoring software to identify leaks and repair them. These software packages send data to a central hub about pipeline conditions, existing and potential leaks and areas that need urgent attention. Leak monitoring systems have saved millions of gallons of water from being wasted even before they reach homes or industries.

Water Efficient Showers

Most of us turn on the shower and let the temperature equalize before stepping in. In these few seconds or minutes, we waste good quality fresh water which could be used efficiently for some other purpose. There have been several inventions to minimize this wasteful practice. An eco-friendly shower system called Ogishower warms the water to the desired temperature in less than 30 seconds reducing shower time and water wastage significantly. Another device, the Cullector Ultra Efficient Shower, collects the running water and feeds it back into the system and re-filters it at the right temperature.

Waterless Baths

Dry bathing is relatively new yet fast emerging as an alternative to showers. It saves several litres of water and is one of the most efficient ways to conserve water. It mainly involves applying a lotion rich in essential oils, odour eliminating agents and bioflavonoids. It is estimated that dry bathing can save four litres of water per person per day, totalling to many millions of litres per year.

CO2 Cleaning

Water is used extensively for industrial applications as a cleaning agent which results in wastage of millions of litres of fresh water. A cheaper, greener solution involves using solid carbon dioxide in the form of dry ice particles to clean different types of surfaces. CO2 can be obtained from other industrial uses, therefore, it is inexpensive and can help to save significant amounts of water.

All nations, developed and developing, are facing the pangs of scarce water. It is as much a global issue as it is a domestic one. Creating more alternatives, using water intelligently and recycling are some of the ways to address the situation. Conserving our planet and environment is an individual responsibility. Stricter laws and regulation can play a supervisory role but ultimately it waters down to individual sensitivity and sensibility.

It is one of the main goals of the modern society to become independent of energy sources that are not renewable, such as oil, coal and natural gas. The sources we are trying hard to introduce into our daily lives are solar energy, wind power, hydropower and biofuel, to name only a few. Over the past couple of decades, we have come far in making this endeavor a true success, as well as something that will be used to everyone’s benefit. Here are some numbers that point to the fact that renewable energy will be a great source of employment as well.

It has been estimated that during 2015, the number of people employed in the renewable energy sector rose by 5%, meaning that it has reached 8.1 million people. Although the number is rising more slowly than it did during the years that preceded 2015, it is still showing a lot more promise than the employment statistics for the energy sector in general. At first, the countries that offered the highest number of jobs in the renewable energy sector were China, the United States, Brazil, India, Germany and Japan. Nowadays, the market is becoming dominated by Asian countries, which according to the latest statistics, hold a 60% share of all the jobs.

When it comes to specific fields in the renewable energy sector, the one that is growing the fastest is certainly wind power, at least according to the data gathered during 2015. It has experienced a 5% rise on a global scale, which means that it is currently employing 1.1 million people. This is mostly thanks to the latest developments in China, Germany and the United States.

The field with the highest number of jobs is definitely bioenergy. While biomass and biogas employ 822,000 and 382,000 people respectively, the number of jobs reserved for liquid biofuels has risen to a whopping 1.7 million. Considering the fact that in the meantime, the number of jobs has declined by 6%, it seems safe to conclude that bioenergy has nothing to fear when it comes to further growth and development

Another area in which jobs availability is constantly increasing is geothermal (http://exergy-orc.com/applications/geothermal) . According to a survey conducted by GEA (Geothermal Energy Association), 86 out of 100 jobs in the geothermal industry are full time, which makes this business one of the best in the world for the ratio between full-time workers and the total number of jobs. Geothermal provides long-term employment for different people with different background and experience: mechanics, plumbers, pipe fitters, electricians, surveyors, hydrologists, electrical and structural engineers among the others, as the list may still continue.

According to a survey made by the Western Governors Association (WGA), the next future will see a significant increase in geothermal employment all over the world.

All in all, renewable energy is a sector that will yield a significant number of employment opportunities.

Using a rainwater tank to collect water that you can then use for drinking can be a great way of being environmentally friendly. These tanks were traditionally used in the Outback due to the lack of water service to remote areas, but today, many homes make use of rainwater tanks as a way of saving money. However, it’s not quite as simple as buying a barrel and setting it up outside your home. Putting in a rainwater tank and using it to create safe water for your home use requires a little more than that.

Learn About Rainwater Requirements

Each local council in Australia may have their own requirements for installing a rainwater tank on your property. If you plan on connecting your tank to a washing machine or to a toilet, for example, you will need to make certain it contains a backflow prevention device. This device stops the water from flowing back into the city water supply. These devices have to be installed by a licensed plumber and must meet a number of different guidelines.

Your council may have additional regulations that must be adhered to before you can install and use a rainwater tank. Make certain you understand all of these requirements before you install a tank.

Drinking Water

In most cases, you may not want to actually use your rainwater tank for drinking. The Australia Department of Health stresses that any rainwater tanks that are used to collect drinking water need to be well-maintained and cleaned regularly so that the water is as pure as possible. Filtering this water before drinking it is also recommended. Many people who use rainwater tanks in Brisbane use the water for showering, for washing clothes, and for filling their swimming pool while continuing to draw on water supplied by the city mains for drinking and cooking.

Keep Your Rainwater Tank Topped Up

Many people don’t realise that they need to make sure that their rainwater tank doesn’t completely empty. If it does, the cleanliness of the tank can be compromised and the water can become contaminated. To make sure this doesn’t occur, most tanks are connected to the water mains to top them up during dry periods.

First-Flush Rainwater Tanks

If your rainwater tank is a flush-first tank, it will have a device attached to it that actually sends any collected water back into the stormwater system first. When it returns to your system, it will pass through the filters in place by the stormwater system, reducing the amounts of sediment and contaminants that the water may have picked up.

Why Use Rainwater Tanks?

With all these different requirements and regulations that must be followed, is using a rainwater tank really worth it? Honestly, yes. Collecting and reusing rainwater for your toilets and washing can save you a good amount on your water bill by reducing your overall water consumption. You can also use it for watering your plants and your garden. It also helps to remove water from your roof and from collecting in your yard, which can help reduce the risk of costly flooding.
