Best Fertilizers for Beans
The best fertilizers for beans have an NPK value of 5-10-10 and are therefore low in nitrogen (N) and higher in potassium (P) and phosphorus (K). Nitrogen can increase the yield if the soil you are planting in is low in nitrogen (N). If there is sufficient nitrogen (N) present dry beans take in nitrogen through the atmosphere and no nitrogen (N) needs to be added. Phosphorus (P) should be applied as a banded fertilizer and not broadcasted. Potassium (K) should be broadcasted in an amount depending on soil test values. Especially to sandy soils low in potassium (K).

Fertilizers for Beans Buying Guide
Before using any fertilizer you should take soil samples before planting any beans according to the University of Nebraska.
Take the samples from the tillage layer between 0-8”.
Nebraska University warns that no fertilizer should be in contact with the bean seeds when planting.
Granular fertilizers are small tablets or pellets of plant food. This fertilizer is spread directly on the ground without mixing it with anything.
These are designed for gardeners that need long-term feeding solutions. You can even buy a granular fertilizer that is organic to take care of your crops organically.
Granular fertilizers can also be quick-release. These will supply a quick dose of nitrogen to wilting plants.
If you are using a slow-release granular fertilizer, you will have to repeat the application every 3 or 6 months, depending on the brand you are using.

This type of fertilizer can feed the necessary nutrients through the leaves or soil. Choose the liquid fertilizer with the right balance of nutrient ratios or NPK.
Certain liquid fertilizers can alter the soil pH, so make sure you research well about the product you are going to buy.
These fertilizers provide nutrients instantly compared to granules or organic fertilizers that release the nutrients slowly.

Before buying any fertilizer, get your soil tested in a local gardening center. This will give you the complete soil, nutrients deficiencies, and pH level.
To protect the beans plant from burning, avoid adding the fertilizer too close to the stem or foliage. Granular fertilizers should be applied carefully because if they touch the foliage, they can burn the leaves.
Beans thrive in slightly acidic or neutral soil. Meaning your soil pH should be between 6 and 7. The NPK of your fertilizer for beans should be decided after knowing the deficiencies in the soil.
The NPK represents the percentage of nitrogen, phosphorus, and potassium. For example, if your soil test indicates a nitrogen deficiency, you should buy a fertilizer that is high in nitrogen.
These three are the major components for the growth of any houseplants, including beans. But commercial or organic fertilizers also contain trace elements like magnesium, sulfur, copper, etc.
Did you know that beans can produce their own nitrogen, and most gardeners report that this nitrogen is enough for the entire growing season?
I would recommend nourishing your soil to eliminate deficiencies for other elements.
The first application for beans should be done one day before planting. You will thoroughly mix the fertilizer in the garden soil. Make sure it’s mixed 2 or 3 inches deep.
You should reapply fertilizer for beans when the bean pods start appearing or after the blooms have opened.
This ensures a high yield. The second application is usually a row application.
Avoid overfeeding with a nitrogen-rich fertilizer; otherwise, your plant will produce more leaves and fewer beans.
It also increases the pest and disease infection risk.
You should add nitrogen only if the soil indicates nitrogen deficiency or the plant has pale green, yellow foliage.
Phosphorus helps in developing a vigorous roots system for the bean plants.
The most common way of applying fertilizers is row application. In this method, the fertilizer is applied to the sides of the rows before planting the beans.
To add fertilizer for new transplants, dig holes in the soil to fill them with the fertilizer. The plants will be transplanted in these holes.
Some gardeners also add the fertilizer using the broadcast method.
Following are few tips to produce the best bean crop.
- Avoid planting beans in alkaline soils as they will deprive the plant of the nutrients in the soil.
- Avoid over-fertilizing the plant early in the growing season as it prevents it from producing blooms as well as pods.
- If your bean plant has stunted growth and new leaves are turning yellow, your soil has zinc deficiency. Immediately treat with a zinc solution to fix this problem.
- When the plant starts developing bean pods, fertilize with a potassium-rich fertilizer.
- Beans are fast growers, so adding too much plant food can slow down the growth rate.
- Follow the fertilizer label’s instructions for application rates and application methods.
We have shared a complete list of the best fertilizers for beans. This article also gives useful information and tips about feeding beans.
The key point is that beans need a low nitrogen fertilizer to produce the best yield. Your fertilizer should have high amounts of nitrogen and phosphorus.
