What Good Are Fertigator Fertilizer Systems?

Fertigator Fertilizer systems are a type of fertigation system. Fertigation, usually used among landscapers, is a type of automatic fertilizer injection system that can be connected to any in-ground sprinkler system. You might consider this process as a form of "spoon feeding" your soil, since the objective is to send small amounts of fertilizer through an irrigation system each time the system becomes active. The actual process of fertigation has been used in agriculture for over three decades. Even other retail industries have begun using this technology to their advantage.

Fertigator Fertilizer systems refer to a type of fertigation system and one that is sold by the Fertigator Company to consumers or commercial businesses. Fertigator Fertilizer systems are becoming increasingly popular by both personal and professional markets who appreciate the simplicity involved. What are the benefits of these systems? The technology involved (supplying plants with small amounts of fertilizer on a consistent basic and through an irrigation system) allows plants to thrive in a healthier environment. The fertigation process keeps nutrients flowing regularly, and plans need these nutrients if they are to grow. Some landscapers might recommend slow-release fertilizers instead of fertigation systems (since seemingly, these fertilizers would perform the same action), however, these systems are more time consuming and tend to be on the expensive side.

When you compare Fertigator Fertilizer systems to the "traditional" way of monthly fertilizing lawns then you also see a huge difference. Traditional fertilization tends to overfeed plants, as plants use up most of the nutrients in the first few days following treatment. (Sort of like your goldfish) So essentially, after some time passes, you "starve" your lawn of these nutrients, at least until you administer treatment a second time. Feast or famine, indeed. Traditional fertilizer also uses a heavy amount of chemicals. Unnatural chemicals plus long starvation periods plus initial overfeeding does not exactly prime your lawn for its fullest potential. Besides, this unhealthy process is also very time-consuming for the average homeowner.

Fertigator Fertilizer systems are a welcomed relief to anyone who has ever toiled over the traditional irrigation process. Fertigator Fertilizer systems automatically fertilize your lawn every time the sprinkler system comes on. This process feeds plants nutrients on a regular basis so that both overfeeding and starvation effects are eliminated. The company also arranges for some types of maintenance, for example, state-licensed pest control. However, much of the maintenance you would expect is not needed because the fertilizer is organic and has natural weed repellants. All the maintenance that is really necessary is that you refill the fertilizer container. All in all, Fertigator Fertilizer systems are designed to be mostly maintenance free.

FertiGator products are available at over 500 wholesale distributors, as well as through online purchase. The company also works with contractors so customers have the option of professional installation, though DIYers should have no problem. If you are looking for a convenient and healthy solution to lawn irrigation, then dig into Fertigator Fertilizer systems for the best results.

Fertigation Methods

Fertigation, as the name implies, is the applying of fertilizers through irrigation water: Fertilization + Irrigation. This relatively new technique is being more and more commonly used in recent years, but the term "fertigation" is still not well recognized and many have not heard it.

Fertigation has many advantages over other fertilization methods, and when properly used, it saves time and labor, fertilizers application is more accurate and uniform, and nutrient uptake by roots is improved.

Two methods of fertigation: quantitative and proportional

When using fertigation, fertilizfers solutions are prepared in advance in stock tanks and the solution is then injected into the irrigation water. The most common fertigation methods to do so are the quantitative method and the proportional method.

The quantitative method is commonly used in soils. In this fertigation method, the grower first decides how much fertilizer he needs to apply per area (e.g. kg/ha, lbs/acre). This quantity of fertilizer is then delivered through the irrigation system.

The proportional method is mostly used in soil-less media and sandy soils. In this method a defined quantity of the stock solution is injected into each unit of water flowing through the irrigation system (e.g. l/m3, lbs/gal).

Some fertigation controllers allow the grower to directly determine the required injection rate, while other controllers require the input of time and flow parameters (irrigation flow rate, irrigation duration, injector discharge, injection duration).

Irrigation system design for fertigation

Effective fertigation requires knowledge and proper management. In fertigation, fertilizing is an integral part of the irrigation system and therefore, the irrigation system has to be properly designed. Here are some examples to be taken into consideration for a good design:

Irrigation flow rate should correlate to the injector discharge. For example, if the irrigation flow rate is too high, it won't be possible to inject the full amount of the needed fertilizer.
Installing one-way valves in appropriate places in the system prevents back flow of fertilizers to the pumps or into drinking-water lines.
Water meters installation is highly important.

The whole system should be well calibrated, including injectors, water meters, EC and pH sensors. Inaccurate readings may result in untoward results, damages to the irrigation system and plants and obviously, the efficiency of fertilization is reduced.

Importance of fertilizers solubility in fertigation

Not all fertilizers can be used in fertigation: only water soluble fertilizers are appropriate, but bear in mind that they differ in their solubility under the same conditions. Moreover, the solubility of each fertilizer may change under different pH and temperatures.

Mixing different fertilizers in the same stock tank may also affect their solubility. More importantly, some fertilizers cannot be mixed together because of interactions that result in insoluble salts which clog the irrigation system and reduce the efficiency of fertigation (see Solubility article).

Irrigation system plugging hazard: causes and solutions

Fertigation is commonly practiced using micro-irrigation systems, which are highly susceptible to plugging. The causes of plugging may be particles in the water, precipitation of salts or bacteria and algae growth.

Particles of sand and suspended debris are usually too large to pass through emitters, while silt-sized and clay-sized particles do not normally cause emitters plugging. This kind of plugging hazard can be predicted by measuring turbidity and performing laboratory filtration test. Plugging with sand particles and debris can be prevented by adequate filtration.

In fertigation, the irrigation water contain a relatively high concentration of dissolved salts. If the pH of the irrigation water is above 7.0, or if one or more minerals are in excess, precipitation and emitter plugging is highly probable. Precipitates of Calcium and iron minerals are the most common. Preventing plugging in this case is by keeping the pH of the irrigation water below 7.0 (slightly acidic) and avoiding excessive application of fertilizers, beyond the crop requirements. Flushing the irrigation system before or after each irrigation cycle can also prevent salt accumulation.

High levels of iron and hydrogen sulfide promote growth of bacteria, which create slime. Algae can also create slime. Slime accumulates in different parts of the irrigation system and may cause emitter plugging. Reddish slime indicates presence of iron bacteria, while yellowish to white slime suggests that sulfur bacteria are active. Preventing plugging by slime can be achieved by chlorination. If the source water is not chlorinated, it is a good practice to inject chlorine upstream to the filtration system.

Annual maintenance of the irrigation system is extremely important for keeping the system in good condition.

Tanaman selain fertigasi

Tanaman tersebut bukan la secara fertigasi yang memang dibekalkan kepada semua peneroka ka empat saya nie. Antaranya adalah bendir lepas hampir 1 blann dibekalkan baru la tumbuh si pokok bendir nie lepas nie tunggu buahnya jer.

Felda cuma bekalkan pokok kita kena jaga, baja dan siram tiap hari. Bila dan berbuah bendir nie datang la wakil koperasi felda ke setiap peneroka untuk pungut hasil mereka dan dijual kepada Fama. Disamping ingin ikut kempen "edibel Garden" peneroka boleh dapat pendapatan sampingan. Cuma saya ingin ukar la kaedah kat felda nie supaya buat sistem fertigasi lebih terjamin pokoknya. memang masih kurang peneroka yang menggunakan kaedah fertigasi kat tempat saya nie.. ingat klu lulus jer tapak 1/2 ekar saya untuk saya tanam cili padi johor secara fertigasi boleh la promote kat semua peneroka nie.. makan masa jugak la nak meyakinkann peneroka nie.

Sebelah nie cili yang saya guna baja buatan sendiri macam yang saya tgk org buat baja em ue guna gula merah dan bahan2 lain. nie saya asingkan dari sistem fertigasi saya. nie jirus secara manual, pokok usia 1 bulan.

Tgk acam ok jer.. tak der sakit tgk.. sbb mungkin ade halia dan bawang putih agaknya.
