1、Potassium and phosphorus transport and signaling in plants

In this review, we summarize current understanding of K and P transport and signaling in plants, mainly taking Arabidopsis thaliana and rice (Oryza sativa) as examples. We also discuss the mechanisms coordinating transport of N and K, as well as P and N.

2、Functions of Nitrogen, Phosphorus and Potassium in Energy Status and

Here, we grew Nipponbare rice seedlings in a growth chamber for 20 d at 30 °C/24 °C (day/night) under natural sunlight conditions with different nutrient regimes. The results showed that N had the strongest influence on the plant growth and development, followed by P and K.

3、An Overview of Nitrogen, Phosphorus and Potassium: Key Players of

Various types of fertilizers containing essential elements are now being added to agricultural lands for betterment of yield. This chapter is an attempt to highlight the various aspects of three essential macroelements required by the plants, namely nitrogen (N), phosphorus (P) and potassium (K).

Quick guide to fertilizing plants

There are 17 essential nutrients that all plants need, including carbon, hydrogen, and oxygen, which plants get from air and water. Nitrogen, phosphorus, and potassium are needed in larger amounts than other nutrients; they are considered primary macronutrients.

Understanding the Big Three: Nitrogen, Phosphorus, and Potassium

Understanding the “Big Three” nutrients – Nitrogen, Phosphorus, and Potassium (NPK) – is essential for effective fertilizer management in agriculture. These primary macronutrients play a crucial role in plant growth and development. Here’s a deeper look at each of them:

How Nitrogen, Phosphorus, And Potassium Influence Plant Growth

Discover how nitrogen, phosphorus, and potassium impact plant growth, promoting healthy development and maximizing crop yields through essential nutrients.

What Are the 3 Primary Macronutrients Plants Need? How Nitrogen

Nitrogen, phosphorus, and potassium are called macronutrients because plants require them in relatively large quantities compared to other nutrients. These three elements are essential for core functions, from energy transfer to protein synthesis, and from cellular division to stress response.

Phosphorus vs. Nitrogen: Which Nutrient Do Plants Need More?

Plants require macronutrients in relatively large quantities compared to micronutrients. The three primary macronutrients are nitrogen (N), phosphorus (P), and potassium (K), often referred to as NPK in fertilizers. These elements serve different but interconnected roles in plant physiology:

Are Phosphorus And Nitrogen Required For Plant Growth

Nitrogen is needed for plant leaf and stem growth, while phosphorus is used for energy transfer and potassium for general health. Phosphorus is one of the 17 essential nutrients that plants need for growth and reproduction, and it is considered one of the three major nutrients.

An Overview of Nitrogen, Phosphorus and Potassium: Key Players of

This chapter is an attempt to highlight the various aspects of three essential macroelements required by the plants, namely nitrogen (N), phosphorus (P) and potassium (K).

Plants absorb essential elements such as nitrogen (N), phosphorus (P), and potassium (K) during growth, which play critical roles in plant development, yield, and quality. Rational application of NPK fertilizers is key to improving crop productivity and quality. Below are plant categories that require supplemental NPK nutrients, along with their characteristics:

1. Cereal Crops: Rice, wheat, maize, sorghum, barley, oats, rye, millet, buckwheat, and Job's tears exhibit high NPK demands. These crops require substantial nitrogen for leaf growth and photosynthesis, phosphorus for root development and seed germination, and potassium for stress resistance and quality improvement.

2. Economic Crops: Cotton, rapeseed, peanut, soybean, potato, sugarcane, beetroot, tobacco, grapevines, apple, pear, peach, apricot, plump, cherry, strawberry, blueberry, persimmon, jujube, walnut, olive, Sichuan pepper, and tea plants demand significant NPK. Nitrogen promotes foliage growth, phosphorus supports root systems and germination, while potassium enhances resilience and product quality.

3. Vegetables: Tomatoes, peppers, cucumbers, eggplants, zucchini, pumpkin, winter melon, radish, Chinese cabbage, spinach, celery, lettuce, arugula, kale, cauliflower, onion, garlic, green onion, leeks, asparagus, mushrooms, enoki, shiitake, oyster mushroom, and white jelly fungus require abundant NPK. Nitrogen drives leaf expansion and photosynthesis, phosphorus aids rooting and seed initiation, and potassium improves stress tolerance.

4. Fruit Trees: Apple, pear, peach, cherry, apricot, plump, citrus, grapevine, pomegranate, persimmon, jujube, walnut, olive, Sichuan pepper, and tea trees necessitate high NPK levels. Nitrogen sustains foliage growth, phosphorus facilitates root establishment and fruit set, while potassium strengthens disease resistance and fruit traits.

5. Ornamental Flowers: Roses, chrysanthemums, peonies, lilies, azaleas,百合（lilies）, orchids, calla lilies, Cymbidium, hyacinths, tulips, narcissus, gloxinias, hostas, geraniums, dianthus, violets, snapdragons, and petunias demand notable NPK inputs. Nitrogen encourages lush leaves, phosphorus supports root health, and potassium boosts environmental adaptability.

6. Ornamental Plants: Orchids (Phalaenopsis, Dendrobium), Cymbidium, Coryanthes, Cattleya, hyacinths, tulips, narcissus, calla lilies, hostas, geraniums, dianthus, violets, snapdragons, and petunias require balanced NPK. These nutrients collectively enhance vegetative growth, root vitality, and aesthetic quality.

7. Turfgrass: Bermuda grass, tall fescue, bluegrass, and zoysia grass benefit from NPK fertilization. Nitrogen ensures turf density, phosphorus promotes root penetration, and potassium improves wear tolerance and color retention.

8. Medicinal Herbs: Ginseng, Astragalus, Angelica sinensis, Ligusticum chuanxiong, Atractylodes, licorice, and goji berries exhibit heightened NPK requirements. Proper nutrient ratios optimize medicinal compound synthesis, root expansion, and overall plant vigor.

9. Other Crops: Sweet potatoes, potatoes, and peanuts also heavily rely on NPK. Balanced fertilization ensures robust tuber/root formation, foliar development, and post-harvest storage stability.

the above-listed plants universally demand adequate nitrogen, phosphorus, and potassium. In agricultural practice, tailored NPK application based on crop-specific growth stages optimizes yields and quality. Integrating organic matter and microbial fertilizers further sustains soil health and nutrient balance.
