How to Fertilize Potatoes: A Nutrient Guide for Optimal Growth
How to Fertilize Potatoes?
To fertilize potatoes, start by adjusting the pH of the soil to between 6.0 and 6.5.
One week before planting seed potatoes, apply fertilizer to the soil.
Once the potato plants start sprouting, use a calcium-rich fertilizer to counteract rust spot.
Throughout the growing season, apply a water-soluble tomato/veggie/potato fertilizer on a frequent basis if the soil is nutrient-deficient.
Stop fertilizing about a month before harvesting the tubers.
Different types of fertilizers, including organic and synthetic options, can be used for potatoes.
Granular fertilizers are slower-release, while water-soluble formulas provide nutrients quickly.
Nitrogen, phosphorus, and potassium are key nutrients for potato plants.
Avoid using fertilizers significantly higher in nitrogen than in phosphorus.
Test the soil to determine which specific nutrients need to be added.
It’s important to consistently fertilize potatoes, especially when grown in nutrient-deficient soils, although potatoes planted in naturally-rich soil may not require additional fertilization.
Some popular organic fertilizers for potatoes are compost, aged manure, and seaweed extracts.
Additionally, YaraLiva products provide readily available nitrate nitrogen and water-soluble calcium to offset any issues caused by ammonium fertilization.

Did You Know?
1. The use of “green manure” as an effective fertilizer for potatoes can be traced back to ancient Rome. They would plant crops, such as clover or vetch, in between potato plantings to add nutrients back into the soil.
2. Did you know that crushed eggshells can naturally increase the calcium content in soil? Adding crushed eggshells to potato beds can help prevent calcium deficiencies, which can lead to common potato diseases like blackleg.
3. Potatoes are not only a great source of carbohydrates for humans but also provide nourishment for soil. Potatoes have the ability to accumulate high levels of potassium, making them an excellent “bioaccumulator” for soils lacking in this essential nutrient.
4. To optimize potato growth and yield, it’s recommended to plant them in loose soil that is not too compacted. Potatoes prefer loose soil so that their roots have room to expand and grow, allowing them to access water and nutrients more easily.
5. Contrary to popular belief, it’s not necessary to peel and discard potato skins before planting them. In fact, leaving the skin intact can provide additional organic matter to the soil, improving its overall fertility and moisture retention.
Timing Of Fertilizer Application For Potatoes
Fertilizing your potato plants at the right time is crucial for their optimal growth. It is recommended to apply fertilizer a week before planting the seed potatoes. This allows the fertilizer to penetrate the soil and provide the necessary nutrients for the seeds to germinate and develop strong roots.
By fertilizing before planting, you are giving the potato plants a head start in accessing the vital nutrients they need from the soil. These nutrients will support the growth of healthy foliage and promote the development of robust tubers in the later stages.
Adjusting Soil pH For Healthy Potatoes
To ensure healthy potato plants, adjusting the pH of the soil they will be planted in is crucial. Potatoes thrive in slightly acidic soil with a pH between 6.0 and 6.5. This pH range promotes optimal nutrient uptake, encouraging healthy growth and maximizing yield.
If your soil’s pH is outside the recommended range, it is important to make amendments to adjust it accordingly. One effective method is using sulfur to lower the pH of alkaline soils. Sulfur reacts with mineral components in the soil, bringing down the pH level and creating a more suitable environment for potato plants.
Regularly monitoring and adjusting the pH of the soil is crucial to avoid imbalances that can affect nutrient availability and result in various potato plant diseases and deficiencies.

Calcium-Rich Fertilizer For Sprouting Potato Plants
Applying a calcium-rich fertilizer to sprouting potato plants is essential to counteract potential issues like rust spot.
Several weeks after planting, when the potato plants begin to sprout, it is recommended to use a fertilizer that is high in calcium content.
Tomato fertilizers that contain calcium work well for potato plants, as calcium is vital for strengthening cell walls and preventing diseases such as tuber rot.
These fertilizers can be water-soluble, making it easier for the plants to absorb the nutrients through their roots.
By providing calcium to the sprouting potato plants, you are ensuring their healthy growth and reducing the risk of common potato diseases caused by calcium deficiency.

- Providing calcium helps ensure healthy growth and reduce the risk of potato diseases caused by calcium deficiency.
Fertilizing Techniques For Nutrient-Deficient Soils
If you are growing potatoes in nutrient-deficient soils, it is crucial to adjust your fertilizing techniques to compensate for the lack of essential nutrients. Water-soluble tomato, vegetable, or potato fertilizer can be applied on a frequent basis throughout the growing season.
These water-soluble fertilizers contain a balanced mix of nutrients that the potato plants need for healthy growth. By using them regularly, you can ensure that the plants get a consistent supply of essential macronutrients like nitrogen, phosphorus, and potassium.
To determine the specific nutrient deficiencies in your soil, it is advisable to conduct a soil test. This will provide valuable information on which nutrients need to be added in order to meet the requirements of the potato plants.

Ceasing Fertilization Prior To Harvesting Potatoes
As the potato plants approach maturity, it is crucial to stop fertilizing them to allow the tubers to develop fully without excess nutrients. Typically, fertilization should be ceased around a month before harvesting the potatoes.
By halting fertilization, you are helping the potatoes mature naturally and develop the desired qualities. Excessive fertilization in the later stages can lead to problems such as hollow heart, where the center of the tuber becomes hollow and reduces its quality and marketability.
It is important to note that this cessation of fertilization applies specifically to the tubers’ growth stage, as foliage fertilization may still be necessary to maintain healthy plants until the end of the growing season.
- Cease fertilization around a month before harvesting the potatoes
- Excessive fertilization in later stages can lead to hollow heart
- Foliage fertilization may still be necessary to maintain healthy plants.

Frequently Asked Questions
What is the best fertilizer for potatoes?
Potato farmers have found that chicken manure pellets are the optimal choice for fertilizing potatoes. The calcium-rich content of these pellets plays a crucial role in promoting the growth of large, flavorful potatoes. With up to 7% calcium, these pellets provide the much-needed nutrient for the potatoes to thrive. Moreover, the slow release of nutrients from the pellets over a span of 3 months ensures a steady supply of nourishment for the potato plants, further enhancing their growth and yield.
Is urea good for potatoes?
Urea can be beneficial for potato growth as potatoes can effectively utilize urea nitrogen. However, for urea to be used by potatoes, it needs to be converted into ammonium with the help of urease, which is naturally present in potato plants. The presence of urease throughout the potato plant suggests that it has the necessary mechanisms to process and benefit from urea. Therefore, urea can be considered a suitable nitrogen source for potato cultivation.
How long to fertilize potatoes?
To ensure optimal growth and yield, the fertilization process for potatoes is divided into several key stages. It begins by applying a balanced all-purpose slow-release organic fertilizer about a week before planting the seed potatoes. This initial dose promotes healthy root development and provides essential nutrients for the early growth stages. After planting, it is necessary to fertilize again several weeks into the growth process, especially in nutrient-deficient soils, to ensure the potato plants continue to receive the necessary nutrients. Finally, to prevent an excessive accumulation of nutrients in the tubers and achieve desirable size and quality, it is vital to cease fertilization activities one month before the anticipated harvest date.
How do you increase the size of a potato?
Achieving optimal potato size can be achieved through careful management of nitrogen levels. Trials conducted in England have shown that increasing rates of nitrogen can lead to larger tuber size and subsequently improve overall yield. By monitoring and adjusting the timing and amount of nitrogen provided to the potatoes, farmers can ensure the desired quality characteristics and maximize the size of the potatoes they produce. With this knowledge, farmers can manipulate nitrogen levels to increase the size of their potatoes and improve their harvest.
