1、Slow
Comprehensive analysis showed that deep placement of slow-release fertilizer is a sustainable nitrogen fertilizer management mode that helps to balance grain yield, environmental footprint, and economic benefits in southeast China.
2、Effects of different types of slow
Rice yield increased significantly under controlled- release fertilizers, while slow-release fertilizers had little effect on yield, and rapid-release fertilizers had varying effects on yield as they were susceptible to environmental factors.

Application of slow
Abstract Slow-controlled release fertilizers are experiencing a popularity in rice cultivation due to their effectiveness in yield and quality with low environmental costs. However, the underlying mechanism by which these fertilizers regulate grain quality remains inadequately understood.
Estimating thresholds of nitrogen, phosphorus and potassium fertilizer
In this study, we proposed a method that utilizes allowed ranges of partial nutrient balance and yield to estimate the threshold of nitrogen (N), phosphorus (P), and potassium (K) fertilizer applied to rice (Oryza sativa L.) fields in China.
The price of slow-release fertilizers for rice in Xuzhou varies depending on factors such as brand, specifications, and quality. Generally, the cost ranges from 5,000 to 10,000 RMB per ton.
First, it is essential to understand what slow-release fertilizers are. These are high-efficiency fertilizers characterized by their ability to slowly and evenly release nutrients into the soil to meet plant growth needs. Their advantages include reducing the frequency and amount of fertilization, improving nutrient utilization, and minimizing environmental pollution.
Next, local climatic and soil conditions in Xuzhou must be considered. Located in the northwestern part of Jiangsu Province, Xuzhou falls within a temperate monsoon climate zone. The region has distinct seasons, abundant rainfall, and sufficient sunlight, resulting in a relatively long rice growing cycle and higher fertilizer requirements.
When selecting slow-release fertilizers, several factors should be considered:
- Brand: Choosing well-known brands ensures stable product quality and performance.
- Specifications: Select appropriate formulations (e.g., single-granule or multi-granule) based on planting scale and needs.
- Quality: Higher-quality fertilizers improve nutrient efficiency and reduce environmental impact.
- Price: Balance cost and benefits to choose cost-effective options.
To illustrate how to calculate the price of slow-release fertilizers in Xuzhou, consider the following example: If a slow-release fertilizer costs 10,000 RMB per ton, the price per kilogram is approximately 100 RMB. For planting rice on 5 mu (approx. 0.333 hectares), the required fertilizer amount is: [ frac{5 , ext{mu}}{666.7 , ext{m}^2/ ext{mu}} imes 1,000 , ext{kg/ton} = 7.5 , ext{kg} ] Thus, the cost per kilogram would be: [ frac{10,000 , ext{RMB}}{7.5 , ext{kg}} approx 1,333.33 , ext{RMB/kg} ]
this is a rough estimate. Actual prices may fluctuate due to market dynamics. For instance, cheaper alternatives might become available, or prices could rise if supply tightens. it is crucial to monitor market trends when purchasing slow-release fertilizers to make informed decisions.
