Modern irrigation systems require both clean water and precise nutrient delivery to perform efficiently. Without proper filtration, irrigation emitters can clog, and without fertigation systems, crops may not receive nutrients evenly.
At GoldenStar Farming, we supply and install filtration and fertigation systems designed to support drip irrigation and other modern irrigation technologies across Kenya. These systems help farmers maintain efficient irrigation while improving crop productivity.
Why Filtration is Important in Irrigation Systems
Water used for irrigation often contains particles such as sand, silt, algae, and organic debris. If this water enters irrigation pipes without filtration, it can clog emitters and damage irrigation equipment.
Proper filtration helps to:
• prevent clogging of drip emitters
• maintain uniform water distribution
• protect irrigation infrastructure
• improve irrigation efficiency
• extend the lifespan of irrigation systems
For any drip irrigation or fertigation system, filtration is an essential component.
Types of Irrigation Filters We Supply
GoldenStar Farming supplies different filtration systems depending on the water source, irrigation pressure, and farm size.
Screen Filters
Screen filters use a fine mesh screen to trap particles from irrigation water.
They are commonly used in:
• gravity irrigation systems
• irrigation systems with relatively clean water sources
• small farms and simple irrigation installations
Screen filters are easy to maintain and affordable, making them a good option for farmers starting irrigation systems.
Disc Filters (Recommended for Pressurized Systems)
Disc filters contain stacks of grooved plastic discs that trap fine particles as water passes through them.
recommended for:
• pressurized irrigation systems
• drip irrigation systems
• water sources with organic matter or algae
They provide deeper filtration compared to screen filters and are commonly used in irrigation systems covering small to medium farms of up to about 10 acres depending on water quality.
Small Body and Big Body Filters
Filters come in different sizes depending on the water flow required by the irrigation system.
Small Body Filters
Small body filters are suitable for:
• small irrigation installations
• low water flow systems
• smallholder farms
They are compact and effective for systems with moderate water demand.
Big Body Filters
Big body filters are designed for irrigation systems that handle larger water flow.
Advantages of big body filters include:
• higher filtration capacity
• improved water flow
• reduced pressure loss
• longer cleaning intervals
These filters are ideal for larger irrigation projects and commercial farms.
GoldenStar Farming stocks T-shaped and Y-shaped irrigation filters up to 90mm, suitable for different pipe sizes and irrigation requirements.
What is Fertigation?
Fertigation is the process of injecting fertilizer into irrigation water so nutrients are delivered directly to crops through the irrigation system.
This technique improves fertilizer efficiency and allows farmers to control nutrient application more accurately.
commonly used in:
• drip irrigation systems
• greenhouse farming
• vegetable production
• fruit orchards
Venturi Fertilizer Injectors
A common fertigation device used in irrigation systems is the venturi fertilizer injector.
The venturi works by creating a pressure difference in the irrigation pipe which draws fertilizer solution into the irrigation water.
Venturi Sizes Available
GoldenStar Farming supplies venturi injectors suitable for different pipe sizes including:
• 25 mm
• 32 mm
• 40 mm
• 50 mm
• 63 mm
Choosing the correct size depends on the pipe diameter and irrigation flow rate.
Venturi Price Range
Venturi injectors typically range between:
KES 1,500 – KES 5,500
However, a complete fertigation system may require additional components such as:
• bypass valves
• fertilizer tanks
• pressure regulators
• filtration units
These components ensure the fertigation system works efficiently.
Crops That Benefit from Fertigation
Fertigation systems are widely used for high value crops including:
Vegetables
• tomatoes
• capsicum
• onions
• cabbage
• watermelon
Fruit crops
• passion fruit
• citrus
• avocado
Greenhouse crops
• tomatoes
• cucumbers
• peppers
These crops benefit greatly from precise irrigation and nutrient management.
Frequently Asked Questions
Do I need filtration for drip irrigation?
Yes. Drip irrigation emitters are very small and can easily clog if irrigation water is not properly filtered.
Which filter is better: screen or disc?
Screen filters work well for cleaner water sources and gravity systems, while disc filters are recommended for pressurized irrigation systems and water containing organic particles.
How often should irrigation filters be cleaned?
The frequency depends on water quality. Water with more sediment or organic matter may require more frequent cleaning.
Can fertigation be used with drip irrigation?
Yes. Fertigation works best with drip irrigation because nutrients are delivered directly to the plant root zone.
How much does a fertigation system cost?
Venturi injectors typically cost between KES 1,500 and KES 5,500, but a complete fertigation setup requires additional components depending on the irrigation system.
