Planting Hole Application

Young orchards, vineyards, and forestry plantations benefit significantly when plants are given the right start. Applying controlled-release fertilizers (CRFs) directly into the planting hole delivers nutrients exactly where young plants need them most. Unlike conventional fertilizers, whose uncontrolled release can hinder plant development, ICL’s solutions for planting hole application offer a nutrient supply that is carefully matched to crops’ demands, supporting healthy establishment and long-term productivity.

What is Planting Hole Application?

Planting hole application involves placing fertilizer directly in the planting hole before or during the planting of crops, particularly young trees or vines. This method positions the nutrients close to the developing root system, allowing for immediate uptake and early support.

However, applying conventional granular fertilizers in this way can lead to problems: their rapid nutrient release may create high salt concentrations in the root zone, potentially damaging young roots and reducing plant survival. The design of controlled-release fertilizers, on the other hand, specifically avoids this risk. Their nutrient release is gradual and temperature-dependent, providing a sustained, crop-matched supply over weeks or months.

Why Choose ICL Controlled-Release Fertilizers?

ICL’s planting hole fertilizers ensure safe and effective nutrient delivery right from day one. Products featuring ICL’s Resin Release Technology or E-Max Release Technology provide predictable controlled nutrient availability over extended periods, offering immediately available and long-lasting crop nutrition. This approach improves fertilizer use efficiency, reduces leaching, and lowers the risk of root stress due to salinity.

Key benefits of planting hole application with CRFs include:

• Precise nutrient placement – close to the root zone
• Safe, controlled nutrient delivery for up to 18 months – reduced risk of salt stress
• Support for early growth – encouraging uniform crop establishment
• Single-application convenience – reducing labor and input costs

ICL Solutions for Planting Hole Application

The following ICL products are recommended for planting hole use in agriculture:

Agroblen®

Agroblen® is a fully coated NPK fertilizer that delivers controlled nutrient release for up to 18 months. Formulated for permanent crops such as trees and vines, it supports early development and reduces the need for multiple fertilizer applications. Agroblen® is available in a wide range of NPK formulations tailored to different crop and soil requirements.

Agroblen® Tablet

Agroblen® Tablet delivers the same controlled-release technology in a convenient tablet form. Each tablet contains a precise dose of nutrients, simplifying application and ensuring consistency from plant to plant. It’s particularly useful for high-efficiency planting in orchards, vineyards, and forestry operations.

Agroblen® with V-Factor

Agroblen® with V-Factor features a power-packed combination of patented Resin Release Technology for controlled nutrient release and our V-Factor Organic Growth Enhancer. The V-Factor technology reduces osmotic stress, enhances nitrogen metabolism, and boosts root development to increase root weight and improve plant establishment.

Best Practice Guidelines

Four simple practices will help to maximize the effectiveness of planting hole application:

• Placement: Apply fertilizer in the planting hole, close to the root zone.
• Timing: Apply at the time of planting or transplanting.
• Irrigation: Ensure thorough watering after application to support nutrient activation.
• Product selection: Use fully coated controlled-release fertilizers such as Agroblen® for a safe, extended nutrient supply.

A Reliable Start for Long-Term Success

Planting hole application using ICL’s controlled-release fertilizers provides young crops with a balanced and reliable nutrient supply during the critical establishment phase. By reducing nutrient losses and preventing early stress, Agroblen® products help young trees and vines to establish faster and more uniformly, laying the foundations for long-term yield and performance.
