Understanding The Concept Of Fertigation
Use of fertigation is increasing in U.S, Europe and Asian countries as producers strive to be more efficient with production inputs and practice good environmental stewardship. It is usually practiced with high value crops such as vegetables (strawberries, tomatoes, cucumbers, melons, etc.), turf, fruit trees, vines, and ornamentals. The main advantage of fertigation is the application of nutrients at the precise time they are needed and at the rate they are utilized. Yields are optimized and fertilizer costs are reduced because the nutrients are applied when, where, and in the soluble form needed.
Overall, fertigation conserves water and nutrients. Factors to consider with fertigation are • water quality (especially in drip/ trickle systems), • soil type/leaching potential, • daily plant nutrient consumption, • potential nutrient precipitation and volatilization, and • appropriate nutrient materials. Fertigation systems have been developed for many crops to provide nutrient management guidelines. In addition, plant, soil, and water analyses provide information to optimize the whole program.
Perbandingan Antara Fertigasi & Penanaman secara Konvensional
- Risiko (serangan serangga perosak, penyakit & kekeringan) - Fertigasi: Rendah (kerana menggunakan dinding kalis serangga pada rumah lindungan dan tiada masalah penyakit bawaan tanah). Masalah kekeringan pula sederhana (hanya berlaku sekiranya terputus bekalan, lalai atau sistem pengairan bocor). / Konvensional: Risiko serangan serangga & penyakit tinggi. Risiko kekeringan rendah kerana akar pokok boleh mendapat air dari tanah atau air hujan.
- Tenaga Buruh - Fertigasi: Bermusim (tinggi terutama di waktu menanam dan mengutip hasil, tetapi boleh dikontrakkan). / Konvensional: Sentiasa tinggi
- Kesan akibat mengubah anak pokok - Fertigasi: Kurang terencat (cepat pulih kerana sistem pengairan yang lebih efisien). / Konvensional: Terencat lebih lama sebelum pulih.
- Keseragaman Pokok - Fertigasi: Lebih seragam (menerima larutan baja yang sama) /Konvensional: Tidak seragam kerana dipengaruhi oleh kesuburan tanah yang berbeza-beza
- Potensi Hasil - Fertigasi: Untuk setiap pokok, setahun dan seunit luas lebih tinggi kerana lebih pusingan setahun, kepadatan pokok lebih tinggi dan bilangan yang mati akibat penyakit akar adalah rendah. / Konvensional: Untuk setiap pokok sederhana, manakala pusingan tanaman setahun terhad kerana proses penyediaan semula tanah. Untuk seunit luas pula rendah kerana kepadatan pokok lebih rendah dan mudah pula terkena penyakit berjangkit yang dibawa tanah

Krew Agrotek RTM merakam aktiviti Kebun Kami
Selamat Datang Ke Kebun Kami ? Welcome to Our Farm
These are photos of our farm which is located in Benut, Johor, Southern part of Malaysia. Previously, we planted chillies. We have 2 lots of self-construct Greenhouses like these. It's 30'X100' big and can houses 450 points chilly plants. We use fertigation method through drip irrigation and use coco-peat as a media. We have gained a lot of experience through this method and its quite easy to maintain because the watering and fertilizing is fully automated and because of that, we almost don't need to hire anyone to do most of the job. Anyway, we still have to control insects and fungus infections manually. The same goes to pollination process whereby we have to do it ourselves in order to get a uniform fruiting.
Problems in Drip Irrigation/Fertigation - Clogging / Masalah dalam Fertigasi - Penitis Tersumbat
This is specially critical for drip systems that must be kept free from suspended solids and microorganisms that plug the small orifices in the emitters or driper. In the case of clogging of the drip system by bicarbonate precipitation the use of fertilizers with acid reaction partially corrects this problem. However, acid fertilizers cause corrosion of the metallic components of the irrigation system and damage the cement and asbest pipes. Therefore, the periodic injection of acid in the fertigation system is recommended in order to dissolve the precipitates and to unclog the drippers. The following acids can be used phosphoric, nitric, sulfuric and chlorhydric. In the West, HCl is widely used due to its low cost. Acid injection through the system will also remove bacteria, algae and slime. The irrigation and injection system should be carefully washed after the injection of acid.
In Asian countries like Malaysia however, this method is unknown. What is being done to solve this problem is manually unplug the driper from microtube and wash it in water. For us, we usually use toothbrush to clean the driper from sediments or unwanted items that clogg the driper. After it is thoroughly clean, then plug back the driper to the microtube. This old method is not practical in a huge fertigation plantation and add costs in terms of labour. So, the best way is still the injection of acid substance in the fertigation system.

Fertigation is the application of fertilizers, soil amendments, or other water soluble products through an irrigation system. Chemigation, a related and sometimes interchangeable term, is the application of chemicals through an irrigation system. Chemigation is considered to be a more restrictive and controlled process due to the potential nature of the products being delivered (pesticides, herbicides, fungicides, etc.) to cause harm to humans, animals or the environment. Therefore chemigation is generally more regulated than fertigation.
Fertigation is used extensively in commercial agriculture and horticulture and is starting to be used in general landscape applications as dispenser units become more reliable and easy to use.
Benefits of fertigation over traditional broadcast or drop fertilizing methods include:
- Increased nutrient absorption by plants
- Reduction in fertilizer and chemicals needed
- Reduced leaching to the water table
- Reduction in water usage due to the plant's resulting increased root mass being able to trap and hold water
- Cost Savings - Usually when factors such as labor, fuel, and interrupted play are factored into traditional fertilizer applications, significant cost savings can be seen from use of
fertigation techniques. Additionally, using fertigation, you can usually get the
same results from using inexpensive liquids as you can from expensive time release
granular fertilizers - Consistent Nutrient Levels - Feeding low levels of nutrition continuously as opposed to intermittent applications provides improved turf consistency.
- Reduced Labor - Fertigation reduces the amount of labor required to apply granular fertilizers or sprayed out foliars.
- Low operational costs

Basic Need For Fertigation - Selected Seeds
This is very important in order to get a quality crops. It is recomended to use only Hybrid F1 seed or Precision seed. Hybrid seed is produced by artificially cross-pollinated plants of the best quality. Hybrids are bred to improve the characteristics of the resulting plants, such as better yield, greater uniformity, improved colour, improved taste, disease resistance and so forth. Make sure you get it from a reputable supplier. Hybrid seed cannot be saved, as the seed from the first generation of hybrid plants does not produce true copies, therefore new seed must be purchased for each time you want to plant for the next season. Hybrid seed is also a bit more expensive than the normal seed.
___________________________________________________________________
Mendapatkan benih yang betul adalah sangat 2 penting dalam pertanian berkonsep moden. Kami mengesyorkan hanya benih jenis Hybrid F1 atau 'Precision seed'. benih hybrid dihasilkan secara pendebungaan-silang tanaman dari kualiti yang paling baik. Hybrid dibiakkan untuk meningkatkan sifat tanaman yang bakal dihasilkan seperti hasil yang lebih baik, keseragaman, warna dan rasa yang lebih baik, ketahanan dan sebagainya. Benih hybrid tidak boleh diguna semula untuk semaian selepas generasi yang pertama kerana generasi benih yang berikutnya tidak akan menghasilkan kualiti yang sama seperti yang asal. Harganya pula lebih mahal daripada benih biasa
Basic Need For Fertigation 5 - E.C, pH & TDS Meter / Keperluan asas Fertigasi 5 - E.C, pH & TDS Meter
Measuring the water supply TDS
These tools are to measure the nutrient solution, water supply and the media scientifically and accurately. This is the most crucial and important element in precision farming concept - to be precise in every measurement in order to get a standard and uniform crops quality. TDS (Total Desolved Solids) is to measure water quality before it can be use for plants. You cannot get a reading better than TDS zero when measuring the total amount of dissolved solids in water. As for E.C, it measures the electro conductivity of solutions. In other words, we obtain the concentration of nutrients by using this tool and its the most frequent tool used in Hydroponics, Drip Irrigation or Aeroponics. As for pH meters, please make sure you have a reliable pH meter and know how to calibrate it properly. If your pH drifts off too far, you will find that your plants are not growing as strongly as you would like them to. This has got a lot to do with the availability of Iron in solution. If the solutions or the media is too acidic (whether it is perlite, cocopeat, wood husks etc.), it can actually preventing the roots from absorbing the nutrient resulting a slower growth and low crops yield

How To Shape your Pumpkin & Watermelon?/ Bagaimana Hendak Membentuk Labu Mickey & Tembikai berbentuk Petak?
Mickey-shaped Pumpkin
To get the shape the pumpkins are grown within a mould. Apparently the pumpkins are so strong that when they grow larger they can break through the mould.
Square watermelon.
It costs 15000 yen, which roughly equals $146. That's right, one hundred and forty-six Dollars for one.
They are grown in clear square containers and are prized for the following:
1) The square shape makes them easy to store in small refrigerators,
2) They are grown one melon to a plant. That makes the melon INCREDIBLY tasty as all of the nutrients are concentrated on this one melon. That is also why it costs so much.
