Things to Consider When Buying Best Fertilizer for Carrots and Beets

a) Healthy Nutrients

Ensure that your fertilizer of choice has the required nutrients in the proper proportions. It should contain the three basic nutrients: nitrogen (N), phosphorus (P), and potassium (K). Some fertilizers also contain certain “micronutrients,” such as zinc and other metals, that are necessary for plant growth. Ensure to provide your carrots and beetroot with sufficient water, nitrogen, potassium, and sunshine exposure. Healthy nutrients in the soil should nourish your vegetables and make them safe for consumption.

b) Organic or Synthetic

Organic or synthetic fertilizers influence the growth and yield of your carrots and your beets differently. Plant growth parameters, including height, vary depending on whether you use organic or inorganic fertilizers. You can mix both organic and synthetic fertilizers for maximum results. The best organic fertilizer for beets and carrots reduces synthetic fertilizers’ adverse effects on human health and the environment. Organic manure has nutrients that are beneficial for long–term sustainability and crop productivity. Your choice of fertilizer will depend on the needs of your crops and the availability of organic or inorganic fertilizer.

c) Type of Fertilizer (Granular or Liquid)

Granular and liquid fertilizer applications supply different nutrients. Liquid fertilizers are foliar-applied plant nutrients that are absorbed through the leaves and more readily utilized than when they are ground applied-granular fertilization. Liquid fertilizers can be broadcast or used as a mid-season side dress. Granular-type fertilizer will work well for carrots and beets if used in moderation. Using a liquid-type fertilizer sprayed on the leaves is not advised for use in carrots and beets. Liquid-type fertilizers contain too much nitrogen.

d) Right Combination of Elements

Carrots and beets require a specific combination of elements. For example, you need 5% Nitrogen, 15%b phosphorus, and 15% potassium for the proper development of the root plants. Water is also a necessary element as it promotes the absorption of nutrients. Excess fertilizer may cause the splitting of the carrots and the beets and less flavorful crops. The fertilizer should be rich in potassium and phosphate. Since carrots and beets grow beneath the soil, potassium and phosphate are more beneficial and encourage root development.

e) Know Your Soil

If your soil is not rich in nutrients, you will need fertilizer. Test your soil to know the nutrients your soil requires or those in excess. Carrots and beets perform well when the soil temperatures are around 65 degrees F.

Know the type and drainage of the soil. Carrots and beets have different drainage requirements’. Your soil should be free from stones, loose and airy.

Measure the pH of the soil. Your soil should be neutral. When preparing your soil, how deep you dig depends on the varieties you are planting.

Knowing your soil will impact the type of fertilizer you will use. For example, the best organic fertilizer for beets should be lower in nitrogen.

Frequently Asked Questions (FAQs)

i) What nutrients do carrots & beets need to grow?

All plants require potassium, nitrogen, and phosphorus. Potassium increases resistance to diseases; nitrogen is essential for forming leaves, and phosphorus increases root growth and uptake. Carrots and beets require a proper amount of potassium, nitrogen, phosphorus, and boron. Adequately supply your carrots and beets with water because water draws nutrients into the soil for roots to utilize the nutrients. As a farmer, you should work organic matter into the ground and provide supplement nutrients as your plants grow more prominent.

ii) How often do I fertilize carrots?

Before planting your carrots, work organic compost into the soil. Carrots require plenty of fertilizer, but excess fertilizer will lead to less flavorful carrots. It would be best if you started fertilizing your carrots when the top has reached a height of 3 inches. Always water in the fertilizer after every application. Fertilize again when the leaves get 8 inches, and the leaves are pale.

iii) What fertilizer should I use for carrots and beets?

The best fertilizer for carrots and beets should be high in potassium and phosphate and low in nitrogen. Use 5-15-15 which contains 5% nitrogen, 15% Phosphate and 15% potassium or 0-10-10 which contains 0% Nitrogen, 10%,Phosphate and 10% potassium. You are advised to use granular fertilizer because carrots and beets are root vegetables, and granular type fertilizer will benefit the roots.

iv) What kind of soil do carrots need?

Carrots require loose, well-drained soil categorized as Sandy loam soil. The pH should be neutral to alkaline. Carrots require soil that is full of organic matter and well-decomposed soil. The soil should be low in nitrogen.

v) Do carrots and beets need direct sunlight?

Carrots and beets require full direct sunlight for good crop yield. Up to 8 hours of exposure to sunlight is essential for the vegetables’ development. Beets are shade tolerant- they thrive in the sun and the shade- it depends on why you grow the beets. If you want to grow your beets for the leaves, grow them in the shade. When grown in the shade, the roots will be small, tender, and sweet, and the leaves will be plenty and nutritious.

If you want to grow your beets for the roots, then your beets should receive at least 6 hours of sun daily. Sunny beets form larger and sweeter roots than those grown in the shade.

Final Thought

Application of fertilizer to the soil and other soil management activities has become essential in increasing the yields of carrots and beets. Organic fertilizers are the best fertilizers for carrots and beets to eliminate adverse health and environmental effects brought by inorganic fertilizers.
