Row Application in Commercial Agriculture: Maximizing Efficiency and Yield
Row application, a precision farming method widely used in US commercial agriculture, targets fertilizer to concentrated zones, enhancing seedling growth. Fertilizer is applied in continuous bands along row sides, ensuring precise input placement for optimal crop growth, yield, and resource efficiency. This approach is especially common for row crops like corn, soybeans, and cotton, which make up a substantial part of US agriculture. Row application maximizes nutrient delivery directly to the root zone compared to broadcast spreading or foliar spraying.
What are the main benefits of row application?
- Improved Nutrient Use Efficiency: Concentrated nutrient bands ensure nutrients are easily reached and taken up by the roots, enhancing nutrient utilization.
- Enhanced Seedling Growth: Seedlings benefit from the concentrated zone of nutrients, resulting in robust growth and resilience against pests and diseases.
- Reduced Phosphorus Fixation: Banding phosphorus fertilizers near the seed row reduces phosphorus fixation, increasing phosphorus efficiency.
- Efficiency and Resource Management: By targeting nutrients directly to the root zone of crops, row application maximizes nutrient uptake and minimizes losses through leaching or runoff, leading to improved crop performance and reduced environmental impact.
- Economic Considerations: The cost-effectiveness of row application relative to other methods is another factor influencing its widespread use. While row application may require an initial investment in specialized equipment, the long-term benefits in terms of improved crop yields and reduced input costs often outweigh the initial investment.
Common best practices for row application:
- Placement: Fertilizer is applied either to the side and below the seed rows, slightly below the seeds, or in between rows. When the fertilizer is applied in bands near where roots are growing, the nutrients will easily be reached and taken up by the roots.
- Depth: Common practice involves banding fertilizer 2 inches to the side and 2 inches deeper than the seeds or plants. This provides the plants with a concentrated zone of nutrients and can improve nutrient use efficiency.
- Timing: Application can be done before or simultaneous with planting or seed drilling. Split applications are also recommended. Splitting the total nitrogen application, for example, into smaller doses throughout the season can be favourable, especially in coarse soils that have a high nitrate leaching potential.
- Fertilizer Types: Liquid or dry fertilizers can be used for row application.
- Avoiding Seed Damage: It’s crucial not to place the fertilizer too close to the seeds to prevent damage and reduce the risk of salt injury.
- Correct Dosage: Ensure the correct dose of fertilizer is applied to meet the crop’s nutrient requirements without causing over-fertilization (high rates will damage the seedlings).
What Are the Most Common Practices or Techniques for Row Applications in the US?
In the US, several techniques are commonly employed for row application in commercial agriculture:
- Precision Planting: Utilizing advanced equipment to precisely place seeds at specific intervals and depths within rows.
- In-Row Fertilization: Applying fertilizers directly into the soil within rows, targeting the root zone of crops for optimal nutrient uptake.
- Side-Dressing: Supplemental fertilizers are applied alongside rows during the growing season to meet changing crop nutrient requirements. Side dressing is not as effective as preplant banding for immobile nutrients like P since side dressing does not allow time for these nutrients to become available to plants.
- Precision Spraying: Employing precision sprayers with GPS guidance and nozzle control systems to target pesticides or herbicides to specific areas within and between rows.
- Inter-Row Cultivation: Using mechanical cultivation equipment to control weeds between rows without disturbing crop plants, reducing the need for herbicide applications.
- Drip Irrigation: Delivering water directly to the root zone of plants within rows, minimizing water loss and improving water use efficiency in row-crop production systems.
What are the main advantages of row application?
- Precision and Efficiency
- Optimized Crop Growth
- Resource Use Efficiency
- Weed and Pest Control
- Cost Savings
Row application of fertilizers optimizes nutrient delivery to seedlings, fostering healthy growth and improving overall crop productivity. It is a fundamental aspect of modern commercial agriculture in the US, enabling farmers to achieve higher yields, lower costs, and more sustainable farming practices through precision input management.

The four-in-one natural fertilizer
What is Polysulphate (polyhalite)? Made by nature, mined by ICL. Polysulphate® is a naturally occurring mineral fertilizer, polyhalite, mined exclusively by ICL. Available as a granule, sphere, or powder, it is soluble, plant-available, and easy to blend and spread, making it a cost-effective sulfur solution. Deposited in the earth 260 million years ago, each Polysulphate granule naturally contains Sulfur, Potassium, Calcium and Magnesium – four of the six essential macro-nutrients required for optimal plant growth. Since 2010, hundreds of field trials have been conducted worldwide demonstrating Polysulphate’s efficacy in improving both crop yield and quality. Why is Polysulphate more effective than other forms of sulfur? Polysulphate—a better source of Sulfur As a naturally occurring sulfate-based multi-nutrient, polyhalite, Polysulphate requires no chemical separation or industrial processing, delivering high agronomic value for low environmental impact. Providing a season-long source of plant-available nutrients, Polysulphate’s gradual release pattern safely meets peak plant demand and improves nutrient use efficiency while reducing risks of leaching. It is proven to produce a healthier and more productive crop across a wide variety of soil types. Low-chloride, low salt index, neutral pH and no liming effect make it a safe choice even for sensitive crops. Natural, certified-organic, low carbon footprint. Polysulphate is a natural product with a low carbon footprint, licensed for use in organic farming systems. Polysulphate sets the standard in environmental sustainability among fertilizers, with Polysulphate Standard, and Granular having the the lowest carbon footprint (compared to similar products) of just 0.029 kilograms of CO2 equivalent per kilogram of product. Polysulphate is suitable for organic farming systems and is approved for organic use by several certification agencies around the world, including Ecocert, Ceres, and OMRI.
