Advantages of a Class A High Solids Liquid Biofertilizer Product

The Lystek technology produces a concentrated high solids liquid product, LysteGro, that is considered a Class A biosolids in the US and a Canadian Food Inspection Agency (CFIA) registered fertilizer in Canada. LysteGro has a solids content that generally ranges from 13 – 16 % with a viscosity below 8,000 centipoise, which means that it is fully pumpable using traditional liquid manure handling and application equipment. There are several advantages to managing a Class A high solids liquid product outlined below:

Simple and Cost Effective Liquid Pumping and Storage Systems: Pumping LysteGro from processing to storage, and from storage to truck loading is completed with standard pumps proven within the industry. This allows for rapid, low maintenance pumping operations, and accurate quantification of the volumes. Liquid solutions offer automation that is not possible compared to solid loading operations which often required manned loading equipment. Concentrated liquid storage solutions reduce real estate footprint compared to solid options as storage tanks can be constructed with practically unlimited vertical storage capacity unbound by the slumping properties of dewatered biosolids.

Loading and Unloading Efficiencies: Depending on the site requirements and product volumes, loading of tanker trucks can be completed very efficiently (5 – 10 minutes at larger facilities) and accurately. Additionally, in the field, the tankers can be unloaded in as little as 5 minutes. The result is an efficient and clean program at both the loading and field sites with minimal staffing requirements.

Odor Management: From the point of production to application in the field, the product is completely contained within enclosed reactors, piping systems, enclosed storage, tanker trucks, and finally the soil. This is a significant advantage when managing odor concerns throughout the lifecycle of the product. The Lystek system generates minimal process air compared to dry alternatives which require the evaporation of water, and in the process, the liberation of odorous compounds that must then be captured and treated.

Application Efficiency and Cost Effectiveness: Due to the loading methods at the WWTP and in the field, LysteGro application programs are very efficient. At the field, the product is transferred directly from the highway tanker to the field tanker and injected into the soil, requiring only one pass. This translates to less equipment, less man power, and less time spent on customer’s fields.

Application Accuracy and Nutrient Use Efficiency: The application rate is controlled with flow meters and GPS systems to ensure it is placed evenly and accurately throughout the field. This provides the farmer confidence that they can rely on the material as a synthetic fertilizer replacement. This also creates opportunities for farmers to utilize their GPS technology to place the seed close (within 2” for example) to the band of LysteGro to optimize nutrient use efficiency of the product. The sub-surface injection of the product minimizes nitrogen loss, maximizing the effective nutrient value of the product.

Environmental Protection: LysteGro is sub-surface injected, which increases soil contact, and essentially removes the risk of run-off. Additionally, because the material is concentrated, there is a dramatic reduction in the overall volume that must be applied per acre versus traditional liquid programs. As a result, application above the hydraulic loading rate of the soil is not a concern.

Improved Optics (Out of Sight, Out of Mind): Injection of the product minimizes soil disturbance, and the outcome is a professional job with negligible product on the soil surface, resulting in significantly reduced public concern.

Value Proposition to the Modern Farmer: The value proposition to the farmer is to provide a consistent quality product they can rely on to improve yields and reduce input costs. The Lystek approach to fertilizer management is preferred by farmers compared with historical application methods, as it only requires one pass to inject and incorporate the product. Additionally, it is compatible with minimum till systems, which are rapidly growing in popularity in agriculture throughout North America.
