1、Revisiting potassium

Soil potassium (K) deficit is extremely challenging for global food security, necessitating optimal K-fertilization strategies to reconcile crop productivity and soil fertility.

2、Effects of Potassium Levels on Plant Growth, Accumulation and

Potassium content in the roots, stems, and leaves of seedlings increased with the increasing in K supply (Figure 2). The K content of all organs was the highest under K12 treatment.

3、(PDF) Effects of Agricultural Potassium Fertilizer Application on Soil

This review examines the impact and regulatory mechanisms of potassium fertilizer on the soil carbon cycle, discussing how potassium fertilizer affects soil carbon storage and flow...

4、Effects of Potassium Fertilization Application on Microbial Community

To explore the reshaping effects of potassium fertilization on the microbial community in sugarcane roots and its microbial enrichment characteristics, redundancy analysis (RDA) was employed to identify the driving factors of microbial communities.

5、Effects of Supplemental Potassium on the Growth, Photosynthetic

We studied the effects of different KCl concentration treatments (0, 1, 5, 20 mM) on the biomass, photosynthetic characteristics, and ion content of Zoysia matrella under salt stress (NaCl 300 mM).

Effects of Potassium Levels on Plant Growth, Accumulation and

Potassium content in the roots, stems, and leaves of seedlings increased with the increasing in K supply (Figure 2). The K content of all organs was the highest under K12 treatment.

Effects of Excess Potassium on Plant Health

High potassium concentrations can inhibit root elongation and branching by altering hormonal balances such as auxin distribution that controls root architecture. Smaller root systems limit nutrient uptake capacity overall.

Potassium Improves Drought Stress Tolerance in Plants by

Potassium (K) reduces the deleterious effects of drought stress on plants. However, this mitigation has been studied mainly in the aboveground plant pathways, while the effect of K on root-soil interactions in the underground part is still underexplored.

Effects of nitrogen, phosphorus, and potassium fertilization on plant

Our study indicates that E. scandens seedlings have a stronger sensitivity to N levels than to K or P levels. A deficiency of N caused yellow, scarce leaves, and a low yield whereas excessive N poisoned the roots and adversely affected the growth of aboveground parts of the plants.

Potassium in plants: Growth regulation, signaling, and environmental

Potassium (K) is an essential element for the growth and development of plants; however, its scarcity or excessive level leads to distortion of numerous functions in plants.

Potassium fertilizer plays a critical role in plant growth, influencing not only overall development but also the formation and maturation of roots and stems. Excessive potassium fertilization impacts roots and stems in the following ways:

1. Promotes Formation and Development of Roots and Stems: Potassium fertilizer stimulates root system growth, enhancing water and nutrient absorption capabilities, which improves stress resistance. It also accelerates the development of roots and stems, aiding adaptation to environmental changes.

2. Improves Quality of Roots and Stems: By increasing intracellular potassium concentrations, potassium fertilizer enhances traits such as firmness, toughness, and disease resistance, making roots and stems more durable during storage and transportation.

3. Boosts Yield of Roots and Stems: Potassium fertilizer significantly increases crop yields, especially for potassium-loving plants. This is due to its role in promoting photosynthesis, respiration, and accumulation of photosynthates.

4. Enhances Storage Longevity: Higher potassium levels improve compressive resistance and rot resistance in roots and stems, prolonging their post-harvest shelf life.

5. Facilitates Transportation: Increased potassium reduces starch content while raising sugar ratios, improving the transportability of roots and stems.

6. Improves Appearance and Taste: Potassium enrichment enhances visual appeal (e.g., brighter color) and palatability of roots and stems.

7. Strengthens Pest and Disease Resistance: Elevated potassium levels bolster the immune system of plants, enhancing their ability to resist pests and pathogens.

8. Optimizes Processing Quality: Potassium-rich roots and stems are less prone to browning during processing, preserving their natural color and texture.

9. Supports Regenerative Capacity: By stimulating cell division and elongation, potassium fertilizer accelerates the regeneration of damaged roots and stems.

10. Resilience Against Stress Conditions: Potassium-enriched roots and stems maintain normal growth under adverse conditions like drought or salinity.

potassium fertilizer multifacetedly benefits roots and stems by promoting development, enhancing quality, increasing yield, improving storage and transport, refining appearance, strengthening disease resistance, optimizing processing, supporting regeneration, and boosting stress resilience. Thus, appropriate potassium application is vital for healthy root and stem growth.
