3、Optimized nitrogen fertilizer management for potato in northern China

Based on the NE N application rate (180–186, 180, and 178–240 kg/hm 2, respectively), four N fertilizer treatments were set up in Gansu, six in Heilongjiang and five in Inner Mongolia. The potato tuber yield, N uptake, N use efficiency, soil mineral N content, urease activity were measured.

4、Effect of N Fertilizer Dosage and Base/Topdressing Ratio on Potato

The base N fertilizer dosage largely determined the root morphology, while topdressing fertilizer mainly affected the leaf photosystem, however, rhizosphere topdressing at the early stages of bud emergence did not immediately affect the leaf soluble protein and the sugar content.

In two consecutive years of cultivation, we found that potato tuber yield and Fe content increased in potatoes treated with five iron fertilizer sprays.

Foliar fertilizer for potatoes is a highly efficient nutrient solution applied by spraying onto potato leaves to promote plant growth and enhance yield. Below is a detailed guide on the application methods and dosage for foliar fertilizer specifically tailored to potatoes in Gansu:

I. Application Methods

1. Preparing Tools and Materials

• Ensure tools (e.g., sprayers) are clean and suitable for liquid fertilizer application.
• Prepare the foliar fertilizer stock solution and dilute it to the appropriate concentration following product instructions. It is recommended to follow the dilution ratio specified on the packaging.

2. Choosing the Optimal Time

• Spray during early morning or late afternoon when temperatures are lower, as plants absorb nutrients more effectively. Avoid midday heat, as high temperatures may accelerate evaporation and reduce fertilizer efficacy.

3. Spraying Techniques

• Even Coverage: Ensure uniform distribution across all leaves to avoid over- or under-application.
• Wind Direction: Apply on calm or lightly windy days to prevent fertilizer drift.
• Avoid Direct Sunlight: Refrain from spraying during peak sunlight hours (e.g., intense midday sun).

4. Key Considerations

• Check soil moisture before application. Extremes (too wet or too dry) may impact effectiveness.
• Monitor plant responses. If abnormalities (e.g., leaf yellowing, stunted growth) occur, halt use immediately and consult experts.

II. Dosage Guidelines

1. Determining Fertilizer Amount

• Base dosage on soil fertility, crop requirements, and product recommendations. Start with a conservative amount and adjust gradually.

2. Crop Size and Growth Stage

• Young or early-stage plants: Use lower doses.
• Mature plants: Increase dosage as needed.
• Adjust seasonally: Higher doses may be required in spring/summer to support rapid growth, while reduced amounts are advisable in fall/winter to avoid over-nutrition.

3. Additional Factors

• Account for soil type, crop variety, and nutritional needs. For example, certain crops may require higher concentrations of specific nutrients (e.g., potassium).

III. Important Precautions

1. Safety First

• Work in well-ventilated areas to avoid inhaling fumes.
• If skin/eye contact occurs, rinse thoroughly with water and seek medical attention.

2. Environmental Protection

• Use eco-friendly fertilizers to minimize ecological impact.
• Never dispose of excess fertilizer into waterways (e.g., rivers, lakes).

3. Ongoing Monitoring

• Regularly assess plant health and soil conditions post-application to refine strategies.
• Discontinue use if adverse reactions arise and consult professionals.

effective use of foliar fertilizer for potatoes in Gansu requires careful consideration of application methods, dosage, and safety protocols. Proper implementation can significantly boost growth and yields while mitigating environmental risks.
