When many growers first come into contact with organic granular fertilizer, they think it is "high cost and not cost-effective" because its price per ton is higher than ordinary chemical fertilizers. But this algorithm only calculates the purchase cost of fertilizer in a single season, ignoring the comprehensive benefits in multiple dimensions such as soil conservation, agricultural input reduction and quality premium. From the perspective of the whole cycle of long-term planting, the input-output ratio of organic granular fertilizer is much higher than that of traditional chemical fertilizers.

First of all, there is the hidden cost reduction brought by soil conservation. Long-term single application of chemical fertilizers will lead to soil compaction, acidification and soil fertility decline, which will further cause continuous cropping obstacles, dead seedlings and yield decline. Growers have to invest additional agricultural materials such as soil conditioners, rooting agents and fungicides to remedy, and even face direct losses of crop failure or yield reduction. Organic granular fertilizer realizes "planting while improving soil". Each season of application continuously supplements soil organic matter and repairs soil micro-ecology, fundamentally reducing various additional inputs and yield reduction risks caused by soil degradation, and the soil fertility value of the cultivated land itself is also increasing year by year.

Secondly, the investment in agricultural materials and labor continues to decrease. Organic granular fertilizer has comprehensive nutrients and long-lasting release, and its fertilizer efficiency period is usually 2–3 times that of ordinary quick-acting chemical fertilizers. It can significantly reduce the frequency of top dressing and save a lot of labor costs for fertilization. At the same time, with the improvement of soil health and crop stress resistance, the incidence of soil-borne diseases decreases significantly, and crops have stronger drought resistance, cold resistance and lodging resistance, which can correspondingly reduce the use of fungicides, foliar fertilizers, stress resistance regulators and other agricultural materials. For large-scale bases of more than 100 mu, the annual savings on labor and agricultural materials are enough to cover the price difference between organic granular fertilizer and chemical fertilizer.

Thirdly, there is the market premium brought by the improvement of agricultural product quality. This is the most intuitive income increment of organic granular fertilizer. Crops applied with organic granular fertilizer for a long time have sufficient dry matter accumulation in fruits. Fruits and vegetables have high sugar content, strong flavor and good storage resistance, and the rate of commercial fruits is significantly improved. They can be directly connected to premium channels such as high-end supermarkets, organic fresh food and boutique picking, with prices generally 20%–50% higher than those planted with ordinary chemical fertilizers. Grain and oil crops have plump grains and better nutritional indicators, which can increase income through high-quality and high-price orders. The premium income of agricultural products in a single season usually far exceeds the increased input cost of fertilizer.

For farms and bases planning long-term operation, soil is the core means of production. After 2–3 years of continuous application of organic granular fertilizer, the soil will enter a positive cycle of fertility, and the total fertilizer input can be gradually reduced in the future, truly realizing "the more you plant, the more fertile the soil; the more you plant, the more cost-effective it is". In the long run, organic granular fertilizer is not a simple cost expenditure, but a long-term investment in cultivated land assets, and an optimal solution that balances current income and long-term sustainable operation.
