1、Integrating nutrient balance, environmental footprints and nutrient

Here, we evaluated the nutrient balance, GHG and Nr emissions in China’s major potato-growing regions using statistical data between 2011 to 2021 and explored nutrient optimization strategies towards 2060.

2、Regional variation of yield and fertilizer use efficiency of potato in

Results The average YRs of N, P 2 O 5 and K 2 O fertilizers were 8.6, 5.9 and 6.6 t/hm 2, showing N was the most limited nutrient for potato yield in China. Among different regions, the average attainable yield and YR of N ranked first in NE region (P < 0.05).

3、Frontiers

Methods: This study utilizes a Propensity Score Matching (PSM) model and introduces a novel cost-efficiency approach to analyze and evaluate the production efficiency and economic impact of organic fertilizer application among 546 potato growers in Shandong.

4、Estimating Nutrient Uptake Requirements for Potatoes Based on QUEFTS

We used the Quantitative Evaluation of the Fertility of Tropical Soils (QUEFTS) model to estimate the soil-plant balanced N, P, and K requirements for the potato in China. Our results revealed that there were great differences in the potato yield and nutrient uptake.

April 2025 China Fertilizer Import

Total Imports: 1.234 million tons, import value $391 million, CIF average price $316.86/ton. The decline in international potassium fertilizer prices has driven cost reductions.

Current status and challenges for potato chemical fertilizer

In 2014, the fertilizer application rate per ha for cropland in China was 2.2 times that of the USA, while that for pesticide was 3.4 times the U.S level of the year 2012 (Zhong et al., 2018).

Fertilizer Use in China: Types and Amounts

That means Chinese farmers are not using less organic fertilizer than before, they are using more, but supplementing it with more and more mineral fertilizer to achieve today’s high sustainable yields.

Effects of New Special Formula Fertilizer on Potato Growth

This study addresses the low yield and fertilizer utilization efficiency of potatoes in the arid region of Xinjiang, Northwest China. The effect of a novel, fulvic acid-based specialized fertilizer for drip application on potato growth, development, yield, and fertilizer efficiency is investigated. …

Synergizing potato productivity and environmental performance with

In this study, we hypothesized that NE could improve potato productivity, profitability, and nutrient use efficiency, and synergize productivity and environmental performance by evaluating of N balance as an indicator.

An Evaluation of Potato Fertilization and the Potential of

The results showed that the required amount of NPK fertilizer per ton of potato was 4.85 kg N, 1.26 kg P2O5, and 6.98 kg K2O, respectively.

The price of potato-specific fertilizer in Qinhuangdao varies depending on factors such as brand, specifications, and quality. Generally, prices range from 10 to 50 yuan per jin. Here are some recommendations:

1. Choose Well-Known Brands: When purchasing potato-specific fertilizer, prioritize reputable brands, as their products are more reliable in terms of quality. While these brands may be pricier, they offer better guarantees for performance.

2. Understand Product Specifications: Prices differ based on the type and formulation of the fertilizer. For example, organic potato fertilizers may cost significantly more than chemical ones. Select specifications that align with your needs.

3. Prioritize Quality: The effectiveness of potato fertilizer directly impacts crop growth. Check for balanced nutrients (e.g., nitrogen, phosphorus, potassium) and ensure it is free of heavy metals or harmful substances. You can also assess quality by inspecting color, texture, or odor.

4. Compare Prices: Evaluate options from different brands and specifications to find cost-effective choices. Stay alert for promotional discounts or seasonal deals.

5. Consult Experts: Seek advice from agricultural specialists, farmers, or local co-ops to determine the best fertilizer for your soil and climate conditions. Local agro-supply stores can also provide up-to-date pricing and product information.

6. Check Shelf Life: Avoid expired fertilizer, as it may lose efficacy. Opt for products with a longer shelf life to ensure optimal results.

7. Storage Requirements: Store fertilizer in cool, dry areas away from sunlight and moisture. Keep packaging sealed to prevent deterioration.

8. Application Guidelines: Follow dosage instructions carefully—avoid overuse or underuse. Apply evenly to ensure consistent nutrient distribution.

9. Precautions: Monitor crop growth and soil moisture to adjust fertilization schedules. Prevent direct contact with water sources to avoid contamination.

when selecting potato-specific fertilizer in Qinhuangdao, balance brand reputation, quality, and price according to your needs. Proper usage and storage are critical to maximizing crop yields.
