Fertiliser Spreading 101: What You Need to Know

Fertiliser spreading involves the application of nutrients to the soil to promote plant growth and boost crop production. It is a fundamental aspect of farming and gardening practices that can significantly impact the health and vitality of plants.

This article serves as a comprehensive guide to fertiliser spreading, outlining everything you need to know to nourish your plants and soil effectively. 

Fertiliser Application Methods


Broadcasting is a fertilizer application method that spreads the fertilizer evenly across a large area, much like casting seeds. This method is commonly used for large fields or gardens. The fertilizer is distributed using spreaders, ensuring a uniform coverage over the soil surface. 


Banding involves placing fertilizer in concentrated bands or rows near the plant roots. This method is more targeted than broadcasting and is often used in row crops. By placing the fertilizer close to the roots, plants can access nutrients more efficiently. 

Foliar Feeding

Foliar feeding involves applying fertilizer directly to the leaves of plants. This method is particularly effective in delivering nutrients to the plant’s foliage now, allowing for rapid absorption. It is useful when plants show signs of nutrient deficiencies, as foliar feeding provides a quick remedy. 


Injection is a method where fertilizer is injected directly into the soil or irrigation system. This precise application delivers nutrients directly to the root zone. Plus, it allows for controlled and efficient nutrient delivery, reducing the risk of nutrient runoff or waste. 

Equipment Used in Fertiliser Spreading

Drop Spreaders

Drop spreaders are equipment used in fertilizer spreading where the fertilizer falls directly down onto the soil in a controlled pattern between the spreader’s wheels. This method ensures a precise application, making drop spreaders suitable for areas with defined boundaries or when accuracy is crucial. 

While drop spreaders are influential for targeted applications, they are generally better suited for smaller or irregularly shaped areas.

Broadcast Spreaders

Broadcast spreaders are commonly used for large-scale fertilizer applications. These machines disperse fertilizer in a wide, fan-like pattern, covering a larger area with each pass. 

The spreading mechanism can be adjusted to control the distribution width and rate, making broadcast spreaders versatile for various field sizes. They are efficient for even coverage on open fields or gardens with minimal obstacles. 

Rotary Spreaders

Rotary spreaders, or centrifugal spreaders, use a spinning disk to throw fertilizer in a circular pattern. These spreaders are efficient for covering larger areas quickly. The spinning action ensures a uniform fertilizer distribution, making rotary spreaders suitable for open fields and large lawns. 

Pneumatic Spreaders

Pneumatic spreaders utilize air pressure to propel fertilizer onto the soil. These machines often have a fan that disperses the fertilizer in a controlled manner. Pneumatic spreaders are commonly used in precision agriculture, where accuracy and consistent application are paramount. 

Factors Influencing Fertiliser Spreading

Soil Type and Composition

Different soils have varying nutrient-holding capacities and structures. Sandy soils, for example, may require more frequent applications as they tend to lose nutrients faster, while clayey soils may retain nutrients but could face issues with drainage. Understanding the soil characteristics helps determine the appropriate fertilizer type and spreading method for optimal nutrient absorption by plants.

Crop Type and Growth Stage

At different stages of growth, different plants need different amounts of nutrients. For instance, a leafy green may need more nitrogen during its early stages, while a fruit-bearing plant might require additional phosphorus and potassium as it matures. 

Tailoring fertilizer application based on the crop’s specific needs and its growth stage ensures that plants receive the proper nutrients at the right time, promoting healthy growth and maximum yield.

Weather Conditions

Weather conditions significantly impact fertilizer spreading effectiveness. For instance, rain shortly after applying may lead to nutrient runoff, reducing the fertilizer’s effectiveness. Also, wind can cause uneven spreading patterns. 

Understanding the weather forecast and adapting fertilizer spreading plans helps optimize nutrient absorption and minimize environmental impact.

Application Rates and Timing

Applying too much fertilizer can lead to nutrient runoff and environmental issues, while insufficient application may result in nutrient deficiencies. The timing of fertilizer application aligns with the crop’s growth stages and nutrient requirements. Additionally, aligning application timing with expected rain or irrigation periods helps in proper nutrient incorporation into the soil.
