Supercharge Your Crops

NPK - It’s Not Enough

While NPK is essential for economic crop production, it's simply not enough. Nitrogen, phosphorus, and potassium are the primary macronutrients required for crops to grow but without proper secondary and micronutrients, you may not be producing the type of yields you are hoping for.

Using only conventional chemical fertilizers could lead to soils with poor structure, depleted nutrients, poor root development, reduced plant maturity, disease and insect damage. Adding in biological nutrient programs from Sigma and Biosphere can lead to healthier more productive agricultural crops.

Improve Soil Fertility. Achieve Higher Yields.

Sigma Biosphere is an innovative program, comprised of a unique combination of microbes with an outstanding research pedigree, which is quickly becoming a popular method to create the ‘ideal’ soil fertility with balanced nutrient concentrations. Using proprietary blends of Biosphere and Sigma Bio products, can supercharge soil that's been depleted after years of traditional fertilizer applications.

Complimenting with Sigma and Biosphere can benefit by:

  • Providing more balanced nutrition
  • Increased nutrient uptake over a longer period of time
  • Improved soil structure
  • Reduced plant stress
  • Improved plant moisture utilization

“Biosphere uses Ultra Technology to create homogenous granules, high in concentrations of calcium, magnesium, and sulfur as well as some needed micronutrients, for a fully controlled 90-day release.”

Complete Nutrition programs for your crops

The Sigma Biosphere concept promotes soil health as well as improved fertility balance. Adding just 5-25% of these products into traditional N-P-K programs can help balance nutrition and soil health, leading to increased crop yields and profitability, no matter the growing environment.
