Plenty of evidence exists showing that using biofertilizers can help keep soils healthy over time and give farmers access to stronger, more resilient crops. For centuries, farmers around the world have utilized the power of nature's own processes via biological methods to enhance crop performance and nutritional value while simultaneously protecting our planet.
When creating biofertilizers, certain helpful microbial strains—like bacteria that can fix nitrogen and solubilize phosphorus—are cultivated under specific growing conditions so they can be produced at high quantities and successfully re-introduced to soils. The microbial activity in these biofertilizers builds up soil quality and strengthens roots, which leads to well-balanced crop development throughout the entire lifecycle of crops being produced.
Advancements in biofertilizer production techniques have continued to produce many new types of biofertilizers including, but not limited to: carrier-based biofertilizers, and liquid biofertilizers, and have resulted in longer shelf lives, higher densities of microbes within each biofertilizer package, and simplified methods of application, and therefore, make producing biofertilizers easier for farmers. Liquid biofertilizers are especially preferred by farmers because they can be absorbed very quickly, distributed uniformly, and apply uniformly to the seeds of plants, in the soil where plants grow, and as a foliar application method.
Understanding the benefits associated with the production and use of biofertilizers will allow farmers and agribusinesses to reduce their reliance on chemical fertilizers, increase soil fertility and grow a more sustainable agricultural future through consistent crop yields for all growing seasons.
