Abstract

Balanced fertilizer use represents a comprehensive approach to plant nutrition that extends beyond the routine application of nitrogen (N), phosphorus (P), and potassium (K). It involves the judicious supply of essential macro- and micronutrient including sulfur, zinc, iron, and boron, based on crop requirements, soil nutrient status, and prevailing agro-ecological conditions. Evidence from long-term field experiments and multi-location studies conducted across Asia, Europe, and developing agrarian economies consistently demonstrates that balanced nutrient management plays a pivotal role in enhancing crop productivity, nutrient use efficiency, and produce quality.
Global research findings indicate that balanced fertilization significantly increases biomass accumulation, grain yield, and nutrient uptake while improving critical quality parameters such as protein content, grain density, oil composition, and micronutrient concentration. In addition to yield and quality improvements, balanced fertilizer practices contribute to improved soil health by enhancing soil organic matter, strengthening nutrient cycling processes, and stimulating beneficial microbial activity. These effects collectively support the sustainability and resilience of intensive cropping systems.
In contrast, imbalanced fertilizer uses, commonly characterized by excessive nitrogen application and the omission of phosphorus, potassium, sulfur, and micronutrients has been associated with soil nutrient depletion, structural degradation, declining factor productivity, and inferior crop quality over time. Such practices not only reduce long-term yield stability but also increase environmental risks and compromise food system sustainability.
This review synthesizes global research evidence on the effects of balanced fertilizer use on crop production and quality. It underscores balanced nutrient management as a fundamental strategy for sustainable agricultural intensification, improved farm profitability, and long-term food and nutritional security under increasing population pressure and climatic variability.
