Reducing Nitrogen And Fertilizer Application On Grazing Grass

Reducing Nitrogen And Fertilizer Application On Grazing Grass (Pasture)

Using a biocatalyst together with fertilizer in grazing pastures to decrease nitrogen use by 95-99%, reduce fertilizer use by 39-84% and greatly increase soil microbiome health.

The purpose of this four-month Irish study was to assess the use of PC3, an organic biocatalyst produced by Bio-Organic Catalyst, Inc. (www.bio-organic.com), together with a new biodynamic fertiliser from Innoparmis Agroscience, and their ability to substitute traditional chemical Urea (UreaMax46 46% Nitrogen from Bayer), while maintaining (or improving) crop yield and quality. The impact on soil fertility and health was also monitored.

Key findings:

• Nitrogen use decreased between 95.1% and 99.2%
• Fertilizer use decreased 39.8% to 84.4%
• Crop yield and quality were unchanged
• Soil organic content increased up to 13%
• Soil moisture content increased 14% to 19%
• Soil fungi content increased 275% to 838%
• Soil active bacteria content increased 409% to 1280%
