Precise slurry application with EVONIR technology

Precise application of slurry according to predetermined crop nutrient requirements and regulations is critical for farmers and growers.

Preventing soil and water pollution, reducing emissions, and increasing resilience to climate change are key.

Dinamica Generale developed EVONIR sensor technology with a clear objective: to use one sensor for several applications. EVONIR mounted on slurry tanks is the right instrument to measure nitrogen (N), phosphorus pentoxide (P205), potassium oxide (K2O) on the go. Many farmers spread animal slurry on their crops, what are the main advantages of using EVONIR technology on tanks?

• Granular analysis and real-time map quality monitoring
• Early analysis of the slurry batch with the EVONIR Near Infra-Red sensor makes diffusion more accurate
• More precise application of plant nutrient balances in corn, grass, wheat
• Immediate information available
• Enables automatic speed control based on kg/ton of nutrients
• Simpler and more accurate sewage documentation for compliance with local regulations
• Savings in mineral fertilizer and sampling costs
• Increased profitability and cash flow: selling kg of nitrogen instead of tons of slurry

There is a great variation in dry matter and nutrients in animal slurry. The variation depends on the type of animal, forage and water mixing. For more accurate fertilization application, it would be useful to monitor the slurry before spreading on the farm.

Farmers and contractors could avoid overfertilization and nutrient losses, which is beneficial to both the environment and agricultural economy.
Although there is the possibility of sampling the slurry basins for laboratory analysis, representative sampling is not an easy task, and agitation of the basins may not be sufficient to ensure homogeneity among the spreader loads. Analyzing the quality of slurry online at a narrow slurry passage point (pipe to fill the spreader or a transport pipe on the spreader during spreading) is the task performed by the EVONIR sensor developed by General Dynamics.
