Sustainable Fertilizer Management

Detailed overview of innovation with sample startups and prominent university research


What it is

Sustainable fertilizer management involves adopting practices and technologies that optimize nutrient use efficiency, minimize environmental impact, and enhance soil health, ensuring long-term agricultural productivity while reducing the carbon footprint of fertilizer production and use.

Impact on climate action

Sustainable Fertilizer Management optimizes nutrient application, reducing greenhouse gas emissions from chemical fertilizers. By promoting efficient nutrient uptake in crops, it curtails nitrogen runoff, mitigating water pollution and eutrophication. This innovation fosters agricultural sustainability, aligning with climate action goals by minimizing the carbon footprint of fertilizer production and application.

Underlying
Technology

  • Nutrient Use Efficiency: Maximizing the uptake and utilization of nutrients by crops is essential to reduce fertilizer waste and minimize environmental pollution. This requires understanding soil nutrient dynamics, optimizing fertilizer application methods, and adopting precision agriculture practices.
  • Alternative Fertilizer Sources: Exploring and developing alternative fertilizer sources, such as biofertilizers, compost, and recycled nutrients, can reduce reliance on synthetic fertilizers, which are energy-intensive to produce.
  • Precision Agriculture: Utilizing data analytics, sensors, and remote sensing to tailor fertilizer applications to specific crop needs and soil conditions can improve nutrient use efficiency and minimize environmental impact.
  • Soil Health Management: Building and maintaining healthy soil is crucial for efficient nutrient cycling and long-term agricultural productivity. Practices such as cover cropping, no-till farming, and crop rotation can improve soil health and reduce fertilizer needs.

TRL : Varies depending on the specific technology and practice. Some sustainable fertilizer management practices, like soil testing and crop rotation, are well-established (TRL 9). Precision agriculture technologies are at varying TRLs depending on the specific application. The development and deployment of alternative fertilizer sources are also at various TRLs, with some biofertilizers already commercially available (TRL 9), while others are still in the research and development phase (TRL 3-5).
