Grower Select 16-3-16 Cal-Mag Triple Iron 25lb (80/PL)

Fertilization is a critical component of plant care, and finding the right balance of nutrients is essential for achieving optimal growth and health. The Grower Select 16-3-16 Cal-Mag Triple Iron Fertilizer delivers a versatile, high-quality solution for growers seeking balanced nutrition with enhanced micronutrient availability. 

Manufactured in North America with top-tier components, this 25lb fertilizer blend is designed to perform across a range of applications, offering exceptional solubility, a complete micronutrient package, and specialized features to suit both professional and hobbyist growers.

Key Features

This fertilizer stands out for its thoughtful formulation and superior performance. Here’s what makes it an excellent choice:

Balanced NPK Ratio

• Nitrogen (16): Supports robust vegetative growth and green foliage.
• Phosphorus (3): Delivers sufficient levels for root development without promoting excessive stretching, making it ideal for compact, controlled growth.
• Potassium (16): Improves overall plant vigor, aiding in photosynthesis, water regulation, and disease resistance.

Calcium and Magnesium

The addition of calcium (Ca) and magnesium (Mg) ensures strong cell wall development, better nutrient absorption, and improved overall plant structure. This balanced formulation is ideal for crops that demand higher levels of these secondary nutrients.

Triple Chelated Iron

Grower Select 16-3-16 includes three forms of chelated iron, ensuring consistent availability to plants even in high-pH substrates. This advanced feature addresses common challenges with iron uptake, helping prevent deficiencies that lead to chlorosis and reduced growth.

Complete Micronutrient Package

Beyond calcium, magnesium, and iron, this fertilizer includes a full spectrum of essential micronutrients such as zinc, manganese, copper, and boron. These trace elements are critical for enzyme function, growth regulation, and overall plant health.

Neutral Potential Acidity

With a neutral potential acidity, the fertilizer maintains stable pH levels in the growing medium, reducing the risk of nutrient lockout and creating an ideal environment for roots to thrive.

Advantages of Using

This fertilizer offers numerous benefits that make it a go-to choice for professional growers and gardening enthusiasts:

• Exceptional Solubility: Grower Select fertilizers are designed for easy dissolution, allowing for precise application through fertigation systems or manual watering. The uniform solubility ensures consistent nutrient delivery to plants.
• Cost-Effective Performance: Manufactured in North America, this fertilizer provides high-quality components at an affordable price. It offers excellent value without sacrificing performance, making it a practical choice for budget-conscious growers.
• Prevents Stretching: The reduced phosphorus content in this formulation helps prevent plants from stretching, resulting in compact and aesthetically pleasing growth. This feature is particularly beneficial for ornamental plants and crops where controlled growth is a priority.
• Versatile Application: The 16-3-16 blend is suitable for a wide range of plants, including vegetables, ornamentals, and flowering crops. Its balanced nutrient profile makes it a versatile utility fertilizer for both greenhouse and field applications.
• Improved Micronutrient Availability: The inclusion of three chelated iron forms ensures plants have access to iron regardless of substrate pH, addressing one of the most common nutrient deficiencies in horticulture.

How to Use

Proper application is essential for maximizing the benefits of this fertilizer. Follow these guidelines for best results:

Mixing Instructions

• Dissolve the recommended amount of fertilizer in water according to the manufacturer’s instructions.
• Ensure the solution is thoroughly mixed to prevent sedimentation and allow for even nutrient distribution.

Application Rates

• Use at the specified rate for your crop type, growth stage, and growing conditions.
• Adjust rates based on environmental factors such as light intensity, temperature, and substrate composition.

Frequency

• Apply regularly as part of a fertilization program to maintain consistent nutrient availability.
• Monitor plant health and adjust the frequency if needed to address specific growth demands.

Compatibility

This fertilizer is compatible with most irrigation systems and can be integrated with other fertilizers or supplements. Always perform a compatibility test when mixing products.

Ideal Applications for Grower Select 16-3-16 Fertilizer

This versatile fertilizer is suitable for a wide range of growing scenarios:

• Greenhouse Crops: Perfect for high-value crops like tomatoes, peppers, and cucumbers, where precise nutrient management is critical for maximizing yield and quality.
• Ornamental Plants: Supports vibrant, healthy growth in flowering plants, shrubs, and foliage crops, ensuring attractive aesthetics and robust health.
• Hydroponic Systems: The highly soluble formulation makes it an excellent choice for hydroponic growers seeking balanced nutrition with minimal residue.
• Field Crops: Offers a reliable solution for larger-scale agricultural operations, providing consistent nutrition to support healthy development and high productivity.

Compared to Similar Formulations

Grower Select 16-3-16 is often compared to 17-5-17, a popular fertilizer with a higher phosphorus content. While both blends deliver excellent results, the 16-3-16 formulation offers unique advantages:

• Lower Phosphorus: Prevents stretching and promotes compact growth, making it ideal for ornamental and container-grown plants.
• Triple Chelated Iron: Ensures better nutrient uptake, particularly in challenging pH conditions.
• Neutral Acidity: Reduces the risk of substrate pH fluctuations, ensuring consistent nutrient availability.
