The urban gardener


The use of organic plant nutrients instead of the man-made chemicals in the hydroponic garden eases the work of a gardener. The matter is that the absence of synthetic chemicals eliminates the problem of ppm amount and pH balance of the water. If there is no need to calibrate nutrients, to check pH level of the water, and calculate fertilizer’s amount, a beginner of the hydroponic gardening will definitely make no mistakes, which means many problems may never occur.

A dual root growing system is made by special composition of the medium in the container: the upper part of the medium is soil or soil substitute, and organic nutrients can be supplied directly to this upper part; the lower half of the medium is some porous material, which retains water, but to which no nutrients are supplied. 

Creating an organic hydroponics system, a gardener may use a standard hydroponic grow container, though a coir fiber container will suit too. The preferred material to put at the bottom of the box is lava rock, which perfectly keeps water. Lava rock is then covered with a thin layer of loose rockwool or coir fiber to divide both medium layers and prevent them from mixing together. The upper half of the container should be filled with a mixture of 1/3 potting soil, 1/3 coarse grade horticulture perlite, and 1/3 large-sized horticulture vermiculite. Such arrangement ensures the upper capillary action of water and protects the bottom of the grow bed from the occasional mixing with any organic particles. 

Using a standard plastic hydroponic grow container one should place a plastic screen lining inside the grow bed, fitting it well at the bottom and on the walls of the container up to their top, also with the aim to protect the water from the small particles in the medium mixture. It is also possible to use a hydroponic container with tiny holes.

One more good choice for the use of organic gardening methods in hydroponics system is coir fiber containers. The filling is the same as described above with the thin layer of loose or strand coir fiber between the two types of medium. 

Such box is then set in the grow bed. Note that the level of the pumped water should be a bit lower than the soil mixture. The secondary root system will be submerged into the water along with lava rock and promote the capillary water flow up into the soil. The lower half of the medium may be watered on a regular hydroponic basis, while the upper one can be moistened just once a day. 

This system allows a gardener to supply nutrients right to the upper part of the medium, where they are vitally important. At the same time, the whole medium structure will be perfectly moistened by the pumped water and the plants will also have constant supply of oxygen and CO2, drawn into their root systems. Finally, proper amount of CO2 will improve the absorption of nutrients by the upper parts of the roots.

Organic vegetable gardening seems to be the trend these days as more people have become conscious of what they are eating. This is because conventional methods which involve the use of harmful chemicals may enter our systems.

In order to control the problem, the US Department of Agriculture has issues a new directive. This encourages farmers to shift to organic farming.

With organic farming, farmers will no longer need to plant crops using genetic engineering, irradiation and sewage sludge. Instead, this will be replaced with crop rotation.

Crop rotation is the practice of planting a different crop in the same area where another crop once occupied. This keeps the soil’s nutrients fertile so it can be used again in the following season.

If you think about it, this approach is easier said than done as farmers are accustomed to the old ways of doing it. To help them change their minds, the government offers incentives and subsidies to farmers who decide to follow this plan.

But the main reason why organic vegetable gardening is so important is the fact that the crops harvested have 50% more nutrients and vitamins compared to that of conventional farming methods.

This means the food they consume will reduce the risk of people suffering from a number of diseases like diabetes, high blood pressure, heart disease and certain cancers.

Children who drink milk will be able to get more anti-oxidants, CLA, Omega 3 and vitamins when this is extracted from pastured grazed cows that will really strengthen their bones and muscles.

You can buy organically grown vegetables from the supermarket. The sad part is the almost everywhere you go, although the packaging comes from Department of Health, Quality Assurance International, California Certified Organic Farmers or the Oregon Tilth Farm Verified Organic, most of these are only 50% to 70% organic.

This is why homeowners who want to eat 100% organic vegetables are encouraged to grow these themselves.

There are two ways to make this happen. First, you buy the seedlings until they grow so you can harvest the. Second, you buy them fully grown and then just plant it into the ground.

Most people prefer the first because it makes them proud to know that what is served on the table was done from scratch.

In both cases, you have to prepare the soil, use compost and make sure that these are safe from threats such as insects, weeds and other animals that will eat what you have planted.

You can fight these with other animals, insects, organic fertilizers, deodorant soap and a few other items which you can find out after doing some research.

For those who don’t have a big garden, they can try growing these organically grown vegetables in containers. They require more water than those planted in the soil so give doses frequently.

There is no doubt that organic vegetables and other products are important these days. If you value your health and those of your family you can buy these from the store or plant it yourself.

For those who decide to buy organically grown vegetables, remember to wash before cooking them. This will remove any harmful substances or residue that may still be there which is invisible to the naked eye.

Picture three ripe red tomatoes arranged on a wooden cutting board awaiting your pleasure. They’ve each come from a different source: can you tell which one was grown organically?

Two of the tomatoes were lovingly tended in backyards - one in a conventional garden and the other in an organic garden. The third tomato came from the supermarket, and it’s easy to eliminate from the guessing game.

The supermarket tomato is the pale red one the size and shape of a tennis ball. Bred for packing, shipping, and storing, (not flavor), this tomato was picked green, has traveled more than a thousand miles from farm to store, and has sat on the shelf for weeks — looking none the worse for wear.

Set this one aside. It was definitely not grown organically.

Two remain. For the sake of the game, they are the same tomato variety, let’s say Big Beef slicers. Bright red, they were just picked and are still warm to the touch from afternoon sun.

It’s not so easy to tell the difference in these; we have to look beyond the surface… literally. The quality of the soil from which they grew is the key element to naming the winner of this game: conventional tomato vs. organic tomato.

The chemicals in the fertilizers used in conventional gardens actually break down the health of the soil. Microbes that are necessary for making soil nutrients available to the plants are killed off.

The dead soil requires increasing doses of conventional fertilizer, and still the plants are malnourished, falling prey to insects and disease. Enter the deadly pesticides, sprayed liberally on the plant.

Now, the game is getting serious. One of the two remaining contestants in our tomato contest had better be carefully washed before being eaten; it’s been dusted with poison.

On the other hand, the organically grown tomato also had fertilizer applied to it, but this fertilizer was made from naturally occurring substances like bone meal, fish emulsion, and rock phosphate. These additions fed the soil and did no harm to the beneficial microbes that make nutrients available for use by plants.

Pesticides probably weren’t necessary because a healthy plant produces its own pest-resistant chemicals. But if there were pests, the organic gardener might have used a home-mixed spray of hot pepper and garlic, or something similarly non-toxic to humans.

There are a few additional techniques the organic gardener probably used, such as tilling in a cover crop to add organic material for the microbes and earthworms to decompose. This process results in a crumbly textured soil that holds moisture and allows the roots to breathe.

But even without the soil improvement from a cover crop, it’s fairly clear which tomato is better for health: the only nutrients that can be found in the fruit had to come from what was available in the soil. The organically grown tomato provides better nutrition.

What is not so clear is which tomato is better for flavor. A test of the ratio of sugar to acid might be made, but that isn’t a big issue. Both the conventionally grown and organically grown tomato are vastly superior in flavor to the poor tomato found in most supermarkets.

The original question in this tomato guessing game was whether you could tell which one of those ripe, juicy tomatoes on the cutting board was organic. Turns out that it’s hard to tell just by looking, or even just by tasting.

So, what’s the big issue? Mainly this: sustainability. Conventional growing depletes and eventually destroys the soil. Whereas organic growing techniques actually build and improve the soil.

In the end, the nutritious organic tomato contributes more to your health, and it is certainly better for the health of the soil from which all future crops will come.

ardening is not as difficult as one may think. It actually helps us to conserve the soil we plant on and also keep our level of trash low. The basic concept of organic gardening is to make full use of the natural resources that one has in the area without destroying any of them. The use of chemical pesticides and chemical fertilizers are not encouraged in organic gardening.

Soil

This is one of the most important things in gardening. The soil is used to contain the nutrients and the water that the plant needs to survive. Although, there are now gardening methods wherein the soil is abandoned in favor of other materials, soil is still the primary medium used for organic gardening and farming.

For those who wish to use soil as a medium for gardening, it is best to choose the kind of soil that the plants you wish to grow are comfortable with. Clay soil is usually ideal for those plants that like watery areas since this kind of soil holds water best. It is not ideal for those plants that like sandy soil, though. Sandy soil drains water the best and is used for plants that do not need that much water or whose roots rot easily if steeped in water for too long.

Compost And Organic Matter

Organic matter is anything that was once alive and is now decaying. These are important in organic gardening because these will serve as compost mixed with some stuff to make them more viable as compost. Organic matter that is great for organic gardening can include fish heads and sometimes entrails, kitchen scraps, grass clippings, manure and many others. Organic matter or compost is often used to condition the soil and in place of fertilizer. Some organic dairy products can also be used for organic matter mixes.

Pest Control

Pest control is one of the major reasons why organic gardening is more expensive than other kinds of gardening. Workers and gardeners need to work overtime in protecting their plants from insects and other animals that are attracted to the plants. Inspecting the plants manually in order to remove damaging insects may be hard work but this is beneficial for the plants and the other animals because you do not use pesticide to control them. The best way in organic gardening in controlling the pest problems is to get the help of some useful insects to control the other insects.

There are some organic pesticides available to make the job easier in organic gardening but some farmers do not like to use these if they have a small garden or field which they can work on manually instead.

Taking care of the environment and the so which give us the food should be the top priority of the farmers and their regulating body.
