SISTEM FERTIGASI & PENGAGIHAN ZAT - Pengenalan / FERTIGATION SYSTEMS AND NUTRIENT SOLUTIONS – Introduction

Tanaman boleh menerima apa jua keadaan siraman/pengairan dan pembajaan. Bagaimanapun, bagi operasi komersial, tujuan utama ialah keuntungan yang memerlukan optimasi dari segi pertumbuhan dan hasil tanaman . Optimasi pengairan & pembahagian zat mineral adalah kritikal unuk menghasilkan kadar pertumbuhan yang optimum.. Optimasi pengairan dan penyaluran zat kepada tanaman hidroponik boleh berubah mengikut:

  • Spesis tanaman yang berbeza
  • Spesis tanaman yang sama tetapi berbeza dari segi kitaran hayatnya
  • Spesis tanaman yang sama tetapi berbeza dari segi musim tanamannya
  • Spesis tanaman yang sama tetapi berbeza di bawah keadaan persekitaran yang berlainan
Kandungan-kandungan Larutan Zat Hidroponik:
Sistem fizikal memerlukan zat disalurkan kepada tanaman. Bagaimana hendak mengukur berapa banyakkah setiap komponen zat yang diperlukan?

Definasi:
  • Irrigasi/Pengairan - Membekalkan air ke tanah kering atau media menggunakan penyalur, paip, terusan dan sebagainya.
  • Fertilizer/Pembajaan - Garam-garam bukan organik yang mengandungi elemen-elemen makro & mikro yang penting untuk pertumbuhan tanaman
  • Fertigasi - Penggunaan zat baja yang lazimnya bukan organik untuk tanaman hidroponik di rumah lindungan hujan dan sistem yang kecil, walaupun sebahagian penggemar menggunakan campuran zat organik
  • Rumusan Larutan Zat - Senarai bahan-bahan zat bukan organik dan kepekatannya dalam unit ppm (part per million) atau mMol (millimole). Ia termasuk juga jumlah sebenar bahan-bahan yang diperlukan untuk mendapatkan kepekatan yang ditetapkan serta tepat dari segi jumlah air dalam takungan, larutan dan sebagainya.

Plants can tolerate a wide range of watering and nutritional conditions…
However…for a commercial operation, the bottom line is profit which means optimizing plant growth and yield. Optimum watering and mineral nutrition are critical for optimum plant growth. Optimum watering and nutritional conditions can vary:
  • For different plant species
  • For the same plant species at different times of its life cycle
  • For the same plant species at different times of the year
  • For the same plant species under different environmental conditions
Properties of the nutrient solution for Fertigation/Hydroponic:

The physical systems required to deliver the nutrient solution to the plants. How to calculate how much of each compound to use.

DEFINITIONS

*Irrigation = The supplying of water to dry land using ditches, pipes, streams, etc.

*Fertilizer = Inorganic “salts” containing the essential macro and micro elements
necessary for plant growth. Also organic compounds that contain
such elements (i.e., manure, fish emulsion, bat guano, etc.) that, when added to
the soil or water, increase it’s “fertility”.

*Fertigation = The use of fertilizers (usually inorganic for commercial greenhouse
hydroponics and smaller systems, though some hobbyists use organic mixtures),
in the appropriate combination, concentration and pH, for every irrigation cycle.

*Nutrient solution recipe = A list of inorganic compounds, and their final
concentrations in ppm (“parts per million” or “milligram per liter”) or mMol
(millimole), etc. This can also include actual amounts of the compounds needed
to achieve the prescribed concentrations, given specific tank volumes, dilution
factors, etc.

Drip Irrigation System of Precision Farming in the US modern farm

This method shows the system of the modern farming concept in which we used to call FERTIGATION (Fertilization and Irrigation) or Drip Irrigation whereby the hidroponic fertilizer (in the form of liquid and pre-determined concentration using the calibrated E.C meter) is transported through a P.E and Poly piping and end at the microtube dripper to individual unit of plant. By using this method, each plan is getting the same and consistent amount and also the same concentration of fertilizer and thus, optimise the fruitings
