1、Fertigation in Greenhouse Production: Criteria for Selecting Fertilizers

A large range of fertilizers, both solid and liquid, are suitable for fertigation, depending on the physicochemical properties of the fertilizer solution. For large-scale greenhouse operations, solid fertilizer sources are typically a less expensive alternative to the commonly used liquid fertilizers.

2、Greenhouse Fertigation: Core Concepts and Practices

Abstract Fertigation is the application of fertilizers to crops using irrigation water, aiming to increase fertilizer use efficiency by 40-60% and reduce leaching.

3、Fertilizers for Fertigation

Fertilizers for Fertigation Abstract This chapter discusses the types of fertilizers that are suitable and compat-ible for fertigation, and types of water-soluble fertilizers.

4、Unit Unit 4 Irrigation and Fertigation in Greenhouses

Fertigation is a precise, controlled and tested method of applying fertilisers, nutrients and other water-soluble products through drip lines and sometimes by micro-sprinkler irrigation systems as per crop requirements, its stage, canopy size, soil or season, etc.

5、Implementing fertigation systems

There are various types of fertigation systems available, each designed to cater to different irrigation methods and crop requirements. The most common types include:

Types of fertigation systems and how to choose the right one for your needs

There are several types of fertigation systems available, and choosing the right one depends on the specific needs of the plants being grown and the scale of the operation. Injectors are one of the most popular types of fertigation systems used in agriculture and horticulture.

Fertigation Systems: Components and Layout

Fertigation systems combine irrigation and fertilization to deliver water and nutrients efficiently directly to plant roots. Essential components include filters, pressure regulators, piping networks, valves, controllers, and fertilizer injection units.

Nutrigation™ (fertigation) with Haifa's comprehensive range of greenhouse fertilizers empowers growers to meet their crops' evolving nutritional needs throughout the growing season, utilizing either straight salts or ready-made blends.

Fertilizer Recommendation and Fertigation Philosophy for Greenhouse

Common methods of fertigation include drip irrigation, sprinkler systems, and micro-irrigation techniques. Drip irrigation is a highly efficient fertigation method where nutrient solutions are...

Maximizing Greenhouse Yields with Fertigation

Fertigation is a revolutionary irrigation method that involves delivering fertilizers and other nutrients directly to the roots of plants through an irrigation system.

Greenhouse fertigation fertilisers are commonly used in modern agriculture to deliver nutrients directly to plant roots via irrigation systems, ensuring optimal growth conditions. These fertilisers vary widely in composition and mechanism, categorized as follows:

1. Urea Urea is a prevalent nitrogen (N) fertiliser synthesized from natural ammonia. When decomposed in soil, it releases ammonium ions (NH₄⁺), which plants absorb as a key nutrient. It is especially suitable for N-demanding crops like vegetables and fruits. excessive use may disrupt soil structure and cause salinization.

2. Calcium Nitrate This nitrogen-rich fertiliser enhances soil water retention and aeration. Particularly effective under drought conditions, it improves crop resilience. Yet, overapplication risks salt buildup, harming soil health and plant vitality.

3. Dipotassium Phosphate A phosphorus (P) and potassium (K) blend, this fertiliser boosts photosynthesis, root development, and stress resistance. Ideal for P/K-intensive crops like legumes and corn, dosage must align with crop needs and soil conditions.

4. Potassium Sulfate High in potassium, this fertiliser regulates plant water balance and strengthens stems against lodging. Suitable for crops like tobacco, potatoes, and beets, but excess use may elevate soil sodium levels, disrupting pH balance.

5. Micronutrient Fertilisers These contain essential trace elements (e.g., Fe, Mn, Cu, Zn, B, Mo). Dosage depends on crop-specific deficiencies: iron prevents chlorosis, manganese aids photosynthesis, copper enhances disease resistance, etc.

6. Organic Fertilisers Derived from animal/plant residues or microbial byproducts, these provide holistic nutrition (humus, proteins, amino acids) and improve soil bioactivity. overuse risks acidification; moderation is critical.

7. Slow/Controlled-Release Fertilisers Designed for gradual nutrient release, these reduce application frequency and suit irregular-demand crops (e.g., orchards, flowers). Higher costs and precise dosing based on crop/soil requirements are key considerations.

Greenhouse fertigation fertilisers offer diverse options tailored to crop needs and environmental factors. Rational selection and application ensure healthy plant growth and sustainable agricultural practices.
