1、Optimizing nitrogen and irrigation application for drip irrigated sweet
In conclusion, the optimal combination of 180 kg/hm 2 and soil wetted percentage of 60 % was found to be suitable for sweet potato cultivation in the study area, considering factors such as soil nitrate-N residue, sweet potato yield and quality, and nitrogen use efficiency.
2、Best Fertilizer for Sweet Potato – Garden Success Guide
Choose a balanced, all-purpose fertilizer with equal parts nitrogen (N), phosphorus (P), and potassium (K), such as 10-10-10. Apply fertilizer before planting and when vines start to spread, but avoid excessive nitrogen early on to prevent lush foliage at the expense of tuber development.
3、Balancing Nitrogen Application to Enhance Soil Health and Mitigate
Taken together, by balancing N fertilization practices and enhancing soil health management, sustainable sweet potato production can be achieved, reducing the environmental and human health risks associated with heavy metal contamination.
4、Can Nitrogen Fertilizer Be Used for Sweet Potato Planting? How to Apply
Role of Nitrogen Fertilizer: Nitrogen promotes the growth of sweet potato plants, including stems, leaves, and roots. It also enhances photosynthetic capacity, enabling better synthesis of organic matter.
Can you use compound fertilizers for planting sweet potatoes?
Yes, sweet potato plants can thrive if you use organic options such as compost, well-rotted manure, or balanced organic fertilizers to support sustainable and healthy sweet potato roots.
Fertilizing Sweet Potatoes: How, When, and What to Use
Incorporate several inches of fully aged compost or well-rotted manure into the planting area. This organic matter improves soil aeration and structure, while providing slow-release micronutrients that support initial growth without causing a sudden surge of nitrogen.

Sweet Potato Fertilization Requirements
Sweet potatoes are tolerant plants to low fertilization and nutrient availability. However, most farmers apply fertilizers to boost their yields for commercial farming.
Yield, nutrition, and nitrogen use efficiency of sweet potato in
Although sweet potato demand nitrogen (N), caution is needed when applying nitrogen fertilization, as excess N causes excessive growth of the shoot and a reduction in the yield of storage roots. This study aimed to assess sweet potato yield and nutrient uptake in response to increasing nitrogen (N) rates.
Sweet Potato Fertilizer Requirements and Recommendations: Management
Use a balanced fertilizer with an NPK ratio appropriate for sweet potatoes, incorporate organic matter, and use slow-release fertilizers for a steady supply. Apply fertilizer before planting or during early growth stages to ensure plants need them most.
Compound nitrogen fertilizer is a chemical fertilizer containing the three primary nutritional elements: nitrogen (N), phosphorus (P), and potassium (K). It is commonly used to enhance plant yield and quality. For sweet potatoes, compound nitrogen fertilizer can provide essential nutrients to support their growth and development.
Firstly, compound nitrogen fertilizer supplies the nitrogen required for sweet potato growth. Nitrogen, one of the key nutritional elements for plants, is crucial for the development and growth of sweet potatoes. The nitrogen in compound fertilizer promotes root growth, enabling roots to penetrate deeper into the soil and absorb more water and nutrients. Additionally, nitrogen stimulates the growth of stems and leaves, resulting in lusher plants that facilitate photosynthesis and nutrient accumulation.
Secondly, compound nitrogen fertilizer provides phosphorus, which plays a vital role in the transport and utilization of nutrients within plants. Phosphorus strengthens root development and extension, enhancing the plant’s stress resistance. It also supports the growth of stems, improving resistance to lodging (collapse). Furthermore, phosphorus aids in fruit formation and enlargement, boosting the quality and yield of sweet potatoes.
Lastly, compound nitrogen fertilizer delivers potassium, another essential element for plant processes. Potassium enhances root absorption and nutrient transport efficiency, increasing the plant’s ability to utilize nutrients. It also promotes stem lignification, strengthening disease and pest resistance. Additionally, potassium accelerates fruit maturation and improves overall quality.
Beyond nutrient provision, compound nitrogen fertilizer improves soil structure and physicochemical properties, creating optimal conditions for sweet potato growth. Nitrogen in the fertilizer combines with soil organic matter to form stable humus, enhancing water retention and aeration. This benefits root development and stimulates microbial activity, thereby increasing soil fertility and productivity.
excessive use of compound nitrogen fertilizer may elevate soil salinity, negatively impacting sweet potato growth and quality. application should be tailored to soil conditions and crop requirements to avoid overuse-related issues.
compound nitrogen fertilizer serves as a valuable nutrient source for sweet potatoes, providing essential nitrogen, phosphorus, and potassium. Proper use can accelerate growth, increase yields, and enhance quality. careful control of dosage and application methods is critical to prevent potential problems.
