| Best Fertilizer for Potatoes in Kenya |
The best fertilizer for potatoes in Kenya is one that is relatively low in nitrogen (N) and contains at least twice as much phosphorus (P) and potassium (K). With so many fertilizers available, it can be difficult for buyers to narrow down their options.
Have you ever grown potatoes and they got too small? If the answer is yes, there are probably several reasons why this happened. One of the biggest questions will be the amount of fertilizer applied. But do you know what is the best potato fertilizer in Kenya?
What Is The Best Fertilizer For Growing Potatoes?
The best fertilizer for potatoes in Kenya is one that is relatively low in nitrogen (N) and contains at least twice as much phosphorus (P) and potassium (K). A good example of a good fertilizer ratio for potatoes would be 5-10-10. A developing potato plant needs less nitrogen to prevent the tops from becoming too lush and susceptible to diseases like potato blight. Higher levels of P and K are needed for potato tubers to grow large and healthy.
Even more important is getting the right ratio of N, P and K for growing potatoes. If you add large amounts of the wrong nutrient like nitrogen (potatoes don't need large amounts of nitrogen, you'll do more harm than good), more on that later.
What to Consider When Choosing the Best Fertilizer for Potatoes in Kenya
While it's easy to assume that all plant fertilizers provide similar performance, several factors affect their functionality. Below are some of the most important features to consider when choosing best fertilizer for potatoes in Kenya
Types; Best Fertilizer for Potatoes in Kenya
When it comes to choosing the best potato fertilizer in Kenya, farmers have a choice of two main types: liquid and granular.
• Granular fertilizers come in coarse granules or powders and release nutrients over time, which is ideal for ensuring proper nutritional balance throughout a plant's life cycle.
• Liquid fertilizers act quickly and are immediately absorbed by the plants in your garden.
Farmers must also decide whether to use organic and inorganic fertilizers or a combination of both. Organic fertilizers contain no chemicals and are made from all-natural ingredients. One of the biggest benefits of organic fertilizers is that they continue to condition the soil over time. However, most products on the market are inorganic and use powerful chemicals expertly formulated to make the soil ideal for growing vegetables. It is important to avoid fertilizers that contain a herbicide, as this can also kill growing potato plants.
Nutrients - Best Fertilizer For Potatoes In Kenya
Before choosing the best potato fertilizer in Kenya, it is advisable to test the soil in your plot to see what nutrients are lacking. The following nutrients are generally beneficial for potatoes when balanced in the right proportions:
• Nitrogen stimulates the development of plant stems and leaves, although excess nitrogen can negatively affect tuber growth.
• Phosphorus leads to higher tuber yields.
• Potassium affects plant production and reduces blackheads.
• Magnesium improves growing conditions in sandy soils with low pH.
• Manganese helps add acidity to high pH soils.
• Boron helps seed potatoes absorb calcium from the soil and improves potato skin texture.
Season and NPK ratio - Best Fertilizer For Potatoes In Kenya
Potato plants take 3-4 months to develop, and as they grow, their fertilization needs change. Consider the ideal NPK ratio, which is the percentage of nitrogen (N), phosphorus (P), and potassium (K) for each growth stage. When planting, an NPK ratio of 15-15-15 is ideal. A month or two after planting, potatoes need lots of nitrogen, so a fertilizer with an NPK of 34-0-0 is the best choice. An NPK of 12-12-17 or 14-7-21 is best for the last few months before harvest when plants need potassium the most.
pH level - Best Fertilizer For Potatoes In Kenya
The ideal soil pH for growing potatoes is slightly acidic, between 4.8 and 6.5. It is important to test the pH level of your soil before planting to determine if fertilizer is needed to raise or lower pH levels. If the pH is too high, apply a horticultural lime to the planting area before planting to bring it down quickly. Throughout the growing season, choose a fertilizer that contains manganese, which will keep pH levels low.
Amount of Fertilizer in Potatoes farming in Kenya - Best Fertilizer For Potatoes In Kenya
The amount of fertilizer a farmer should apply depends on the size of their farm and the quality of the soil. Generally speaking, a 1,000 square foot potato garden requires about 25 kg of fertilizer over the life of the plants. Farmers can use this number to calculate how much fertilizer their specific plot needs.
When Should I Fertilize My Potatoes?
Correct and balanced nutrition is important to increase the size of potato tubers. The nutrients nitrogen, phosphate, potassium, calcium, magnesium and manganese have been shown to affect the size of potato tubers.

Nitrogen Affects the leaf canopy and so Tuber bulking rate; Nitrogen is important for fueling growth and providing high yields. Nitrogen is very much needed during leaf formation and later to increase tuber growth and size, when it ensures optimal photosynthate production in the leaves. Nitrogen feeding at an early stage of crop development will help build the overall size of the leaf canopy, while at later stages of growth, nitrogen use helps maintain canopy greenness and maximize performance.
However, this needs to be balanced as too much early nitrogen can cause excessive vegetative growth to the detriment of tuber formation and too much nitrogen in later growth stages will maintain crop growth and can also result in crop with too many seeds. . . ' Larger potatoes put them at greater risk of rust infection. However, in hot, dry climates where true yield potential and desired tuber size have not been achieved, supplemental nitrogen can support canopy growth and extend volume.
Effect of Nitrogen on Potato Tuber Size - Best Fertilizer For Potatoes In Kenya
Therefore, the correct rate and timing of nitrogen application is important in managing potato yields, tuber size and desired quality characteristics.
This series of trials in Kenya demonstrates that increasing nitrogen levels resulted in an increase in tuber size and therefore an increase in overall yield.
The form of the nitrogen is also important. It is best to use a balance of ammonium and nitrate when planting, but too much ammoniacal nitrogen is a disadvantage because it lowers the pH of the root zone and therefore promotes rhizoctonia. During tuber initiation through tuber growth, nitrate nitrogen has distinct advantages and is the preferred source.

Phosphate Applied After Tuber Initiation Increases Tuber Size, Foliar phosphate, applied after tuber initiation, increases tuber size and therefore increases tuber yield; however, leaf phosphate does not replace applied soil phosphate, and without adequate soil phosphate, early season growth is suboptimal.
Foliar Phosphorus - Effect on Potato Yield
These independently conducted trials in Kenya show a steady increase in yield from foliar phosphate applications after tuber initiation, leading to an increase in tuber size and therefore overall yield.
Potassium is essential for high yields
Potato plants absorb large amounts of potassium throughout the growing season and it is essential for high yields.
Potassium and Potato Production
Potato plants absorb large quantities of potassium throughout the growing season and it is critical for high yields.
Potassium and potato yield
In five trials across three years on K rich volcanic soils, 120kg K2O/ha increased average yields by 10t/ha.
How Calcium Affects the Rate of Increase In Tuber Volume
Calcium is a key component of cell walls, helping to build strong structure and ensuring cell stability. It is critical during cell division and expansion and therefore essential before and during the rapid growth phase of tubers.

Why Potatoes Are Small In Size - Best Fertilizer For Potatoes In Kenya
Magnesium Deficiency Reduces Tuber Size, Magnesium is needed during tuber grow-out, and if supply is limited, tuber size and yield will be reduced. Soils severely deficient in magnesium can reduce yields by up to 15%; in these cases, regular applications of magnesium annually have resulted in yield increases of 1-10% in tests. Potato yield and magnesium
Absorption of magnesium depends on balance with other cations, especially potassium. High concentrations of potassium in the soil can induce magnesium deficiency. Similarly, there may be enough magnesium in the soil, but dry soil conditions may limit uptake; in either case, foliar applications of magnesium can be very effective.
Best Fertilizer for Potatoes in Kenya | Tips!
• Make Sure They Have Excellent Soil Conditions
Potatoes need loose, rich soil to grow. Like any tuber, they need room to breathe and release enough soil to grow.
Potatoes grow on roots sticking out of seed potatoes (last year's crop), so the easier it is for the roots to reach water and spread their glorious mealy tubers, the better. chances of growing excellent potatoes.
The easiest way to grow larger potatoes is in a raised bed, as the soil will retain a loose structure for years without compaction, and as long as you fertilize the soil properly with organic materials such as compost from garden and manure, you can grow potatoes in the same spot year after year if you don't have enough space for crop rotation.
• Use Appropriate Fertilizers for Your Potatoes.
If the potatoes are growing too small, the root cause could be poor soil. Potatoes need high levels of nitrogen, potassium, magnesium, calcium and phosphorus. They are greedy eaters and can decimate all the nutrients in the soil, so if you don't practice crop rotation, you MUST add fertilizer to the soil.
