Fertilizer Injectors

June 7, 2011 By jknatura Leave a Comment

Modern fertilization systems include fertilizer injectors that belong to one of two types: fertilizer injectors that are electrically powered (independently or by a controller), or fertilizer injectors that are mechanically powered by water pressure.

The fertilizer injectors inject fertilizer solutions into the irrigation water. The ratio in which the solution is injected is termed “injection rate”. This ratio can be expressed as percentage or v/v units.

For example – a ratio of 5 liter/m3 means that 5 liters of fertilizer solution are injected into each m3 of irrigation water. The same injector rate can be expressed in percentage as 0.5% (5 liter / 1000 liter x 100) or as 1:200. Higher injector rate means more fertilizer solution is injected into the irrigation water.

There are three essential elements that need to be considered to ensure an efficient operation of injectors: the required injector flow rate, the water pressure and the materials the fertilizer injector is made of.

Injector flow rate

The required flow rate of a fertilizer injector depends on:

the irrigation flow rate
the required fertilization level
the concentration of the fertilizer stock solution

For reaching a certain fertilization level, higher irrigation flow rates require fertilizer injectors with higher flow rates.

For example, if you want to inject 5 liters of fertilizer stock solution into 1 m3 of water, and the irrigation flow rate is 30 m3/hour, you will need a fertilizer injector with a minimum flow rate of 150 liter/hour (30 m3/hour x 5 liter/m3 = 150 liter/hour).

It would be impossible for a fertilizer injector with a lower flow rate, to reach the desired fertilization level.

Use this simple calculation to check whether your fertilizer injector can provide the required fertilizers quantities:

Divide the fertilizer injector flow by the irrigation flow to get the injection rate.

For example, If your fertilizer injector 150 liter/hour and the irrigation flow rate is 30 m3/hour, then the maximal possible injection rate is 5 liter/m3 (150/30), or 0.5%.

If the flow rate of your fertilizer injector is too low, you can take one of the following actions:

Decrease the irrigation flow rate, by irrigating fewer valves at the same time

Increase the concentration of the fertilizer stock solution.

In this case, make sure you don’t exceed the solubility limitations of the fertilizers.

Water pressure and water flow affect the performance of fertilizer injectors.

Water flow through the injector and water pressure in the irrigation line must be adequate for an efficient operation of fertilizer injectors.

For example, if the water pressure in the irrigation line is higher than the maximal pressure against which the injector can work, the fertilizer solution might not be efficiently injected, and the fertilizer injector might even eventually not inject any fertilizers at all.

Some mechanical injectors use the water pressure as their power source (e.g. Dosatron). Such injectors have a characteristic range of water flow in which they can work efficiently. If the water flow through the injector is out of this range, the injector is likely not give adjusted ratio .

Materials a fertilizer injector has to be made of

An additional consideration in choosing your fertilizer injector is the type of chemical that would be injected by it.

Injectors that are used for injecting acid, must be resistant to corrosion. Furthermore, the type of acid makes a difference.

Parts of the fertilizer injector that come into contact with sulfuric acid must be made of acid-resistant rubber, while parts that come in contact with phosphoric acid, must be made of stainless steel.

In fertilizer injectors that are consistently used to inject pesticides, plastic parts should not come in contact with the solution because many pesticides contain chemicals that damage PVC.

Better safe than sorry – buy injectors that can provide slightly higher flows than your maximum requirements.

How to get pregnant with fertility drugs

June 7, 2011 By jknatura Leave a Comment

If you have had a hard time getting pregnant, you may feel like there’s not any hope for you to be able to get pregnant with fertility drugs. The good news is that the advances that have taken place in medicine in the last few decades have been especially good to women who want to get pregnant.  Today, many women who have struggled with infertility for years may find that they are able to get pregnant with fertility drugs.

One of the most common fertility drugs is Clomid. Clomid helps to stimulate ovulation. As you know, the only time that a woman can become pregnant is during ovulation. Clomid is able to help you get pregnant if you have fertility problems that are caused by annovulation (no ovulation) or irregular ovulation patterns.

In addition to getting pregnant with fertility drugs, there are a number of other fertility treatments that doctors have at their disposal today. For example, some women are unable to get pregnant simply because their cervix is too deep. In those cases, the woman may be able to turn to artificial insemination. Typically, a woman undergoing artificial insemination will also take fertility drugs to help her get pregnant, as well.

It’s important to recognize that many fertility problems don’t have anything to do with the woman. In fact, studies show that 40% of fertility problems are due to male infertility, 40% due to female infertility, and 20% due to both. In cases, for example, where the man has low sperm motility, a woman may need t o take fertility drugs to get pregnant because those medications can help to create an environment inside the woman’s reproductive system that is friendlier to those sperm.

There are other, more radical procedures that can help a woman get pregnant along with fertility drugs. Procedures such as IVF, or In Vitro Fertilization, can be used to implant a fertilized egg into a woman’s womb. These procedures tend to be extremely expensive, and don’t necessarily always succeed.

The downside to getting pregnant with fertility drugs is that you are at a higher risk of having a twin or multiple pregnancy if you get pregnant with fertility drugs. Multiple pregnancies pose specific risks for both the mother and for the babies, and a pregnancy with multiples is considered a high risk pregnancy. While not every woman who gets pregnant with fertility drugs will have a twin or multiple pregnancy, ti is a risk that you need to be aware of.

Ovarian Stimulation and Intrauterine Insemination (IUI)

Commonly known as artificial insemination, IUI involves inseminating your uterus with best quality (high motile) sperms of your partner or donor using a tube (catheter) thereby enhancing the chances of pregnancy.  The ovaries are stimulated with FSH or hMG to produce several eggs per cycle.  When the eggs reach maturity, ovulation is triggered by either an endogenous LH surge or by an injection of hCG.  Approximately 36 to 42 hours later, near the time of ovulation, a prepared sperm sample is placed into the upper uterine cavity via a narrow catheter.  This treatment regimen increases the chance of pregnancy.

In Vitro Fertilization (IVF)

IVF is the most well-known of fertility treatments.  In this procedure your eggs are fertilised with your partner or donor sperm outside the womb, in a controlled medical environment for the purpose of re-implantation into your uterus.  It involves series of highly coordinated steps beginning with controlled ovarian stimulation using external hormones, egg collection, fertilisation and transfe

In Vitro Maturation of oocytes (IVM)

In patients with hyper-responding polycystic ovarian syndrome or with history of ovarian hyperstimulation, immature eggs are taken out and cultured in laboratory to mature with small quantities of hormones.  Intracytoplasmic sperm injection (ICSI) is used for fertilization of the matured eggs.  The resulting embryos are transferred into the women’s womb.

Intracytoplasmic Sperm Injection (ICSI)

ICSI is a procedure used as part of an IVF treatment, when the sperm count is either nil or very low in the semen or the quality of sperm is very poor.  In this process an individual sperm is injected into the centre of an egg to achieve fertilization.

Intracytoplasmic Morphologically Selected Sperm Injection (IMCI)

A modified form of ICSI (intracytoplasmic sperm injection), it carefully selects the best quality sperm by magnifying 6000 times more than the conventional ICSI method.  Patients with severe low sperm count may benefit from this technique.

Frozen Embryo Replacement Cycle (FERC)

During IVF/ICSI treatment it is common to have multiple embryos.  The unused good quality embryos produced during your cycle can be frozen and stored for future use.

Blastocyst Transfer

Blastocyst transfer involves identifying the single embryo which is most likely to result in pregnancy.  In this procedure your embryos are allowed to develop in the laboratory to the blastocyst stage (4 to 6 days after insemination, rather than 2 or 3 days after insemination as with conventional IVF) before placing them in your womb.

Assisted Hatching

Assisted hatching helps your embryos to hatch out of their outer shell.  It is used if your embryos have tougher shells than usual.  The technique involves making a tiny hole in the shell, before the embryo is placed into your womb.

Interventional Surgical Sperm Retrieval (SSR)

SSR involves various surgical methods that remove sperm from your partner genitals instead of waiting for the sperm to be ejaculated out.  Once the sperm is removed, it can be used in intracytoplasmic sperm injection (ICSI) procedures.  We offer the following types of SSR techniques:

• Percutaneous Epididymal Sperm Aspiration (PESA)
• Vasal Aspiration
• Micro-Epididymal Sperm Aspiration (MESA)
• Testicular Sperm Extraction (TESE)

Donor Oocytes

The use of donor oocytes (eggs) is an option if you are unable to conceive using your own eggs.  It involves retrieval of eggs from a young and healthy donor and then fertilising with your partner or donor sperm using one of the assisted reproductive techniques (IUI/IVF/ ICSI).  These fertilised eggs are then transferred into your uterus.

If you need a egg donor then

Donor Sperm

Donor sperm are recommended when sperm is absent or non-motile from the semen, often due to genetic causes, chemotherapy, radiation therapy or vasectomy.  This involves fertilising your egg with the donor sperm using one of the assisted reproductive techniques (IUI/IVF/ ICSI).  The fertilised egg (embryo) is then transferred into your uterus to carry out pregnancy.

If you need a donor sperm then
