pH Management in Agriculture and the Advantages of Using Liquid Calcium and Drone Technology


Introduction

Effective soil pH management is crucial in agriculture for optimizing plant growth and soil health. This article explores the importance of pH management, compares traditional lime with liquid calcium, and discusses the benefits of using drones and precision agriculture techniques for product application.


Importance of pH Management in Agriculture

Soil pH significantly influences plant growth by affecting nutrient availability and soil microbial activity. Maintaining the right pH is essential for ensuring that plants can absorb the nutrients they need. Unmanaged pH levels can lead to nutrient deficiencies or toxicities, adversely affecting crop yield and quality.


Traditional pH Management with Lime

Traditionally, agricultural lime has been used to correct soil acidity. Lime is effective but has limitations, including slow reaction time, uneven application, and the need for large quantities to alter pH significantly.


Liquid calcium products, such as offer a modern alternative to lime. These solutions are more concentrated and react faster, providing quicker pH adjustments​​. Trials have shown significant effects on pH levels, with starting pH values increasing from as low as 4.9 to 7.29 after treatment.


These new products open up opportunities for better scheduling and planning as well. Because they react much more quickly (raising pH noticeably within 30 days) a winter pH application can affect growth and yields by early spring. This allows for much quicker feedback on management practices and can drastically improve yields for hay fields by the first cutting.


Precision management with drones

Precision management is a comprehensive approach that uses both traditional and modern tools to gain information at a high level of detail. This information can then be used to precisely control inputs. With drones, we can create zones for a field using topography and erosion, yield metrics from previous years, and GIS analysis. These combined tools let us divide a field into management zones according to characteristics that vary throughout the field.


We then test the soil in those zones to determine the pH and nutrient concentrations. By developing a map of what the field needs in those zones, we can vary the input rates and products used according to those zones. This means we can apply different rates of calcium to match the pH needs of zones in the field to reduce product usage. We can also vary fertilizer application to increase performance of areas that are struggling.


We also use cutting edge products like soil-surfactants that increase the activity and availability of nutrients to plants while reducing runoff. Understanding the needs of different areas of the field allows us to vary the rate of these products as well.


Conclusion

Managing soil pH is a critical aspect of successful farming. The shift from traditional lime to new products, coupled with advanced application techniques like precision management and drone technology, allows farmers to increase yields while spending less than they would on traditional products and practices.
