Sigma 4-4-4 Bio – Large Grade

Sigma 4-4-4 Bio – Large Grade is a balanced, all-purpose biological fertilizer designed to provide complete plant nutrition while enhancing soil structure and long-term fertility. With an even 4-4-4 NPK ratio, this formulation delivers consistent levels of nitrogen, phosphorus, and potassium to support steady growth across all stages of development.

The large-grade granules are engineered for slow, controlled nutrient release, making them ideal for extended feeding cycles in soil-based systems. Their coarse structure improves soil aeration and drainage, helping reduce compaction and create a healthier root zone environment.

Enhanced with biological inputs, Sigma 4-4-4 Bio promotes beneficial microbial activity that drives nutrient cycling and improves nutrient availability. This supports stronger root development, balanced plant growth, and increased resilience in a wide range of cultivation conditions.
