The application of potassium fulvic acid (PFA) is a promising strategy to alleviate the damage to plants and improve soil quality.

3、Potassium in plants: Growth regulation, signaling, and environmental

Potassium has diverse role in plant growth and development. Potassium is responsible for activation of several vital plant enzymes. Potassium regulate water balance in plants and protect plants from abiotic stress-induced damages. Potassium plays a vital role in mitigating oxidative stress in plants.

4、Potassium stimulates fruit sugar accumulation by increasing carbon flow

Potassium (K), known as a quality element, plays key roles in improving sugar accumulation and fruit quality, but the mechanism is largely unknown. This study aims to elucidate how K improves sugar accumulation by regulating carbon flow from source leaves to fruit in Newhall navel orange.

Potassium Affects Citrus Tree Performance

Potassium plays a critical role in tree growth and productivity. The generally accepted idea, that satisfactory vegetative growth of citrus can be obtained within a wide range of leaf K contents, might be related to the high mobility of K in plants, at all levels.

Potassium Promotes Citric Acid Accumulation by Regulating Its Synthesis

Our findings demonstrated that an appropriate level of K enhanced CA concentrations primarily by modulating CA synthesis, as evidenced by the increased activities and gene expressions of citrate synthase (CS) and phosphoenolpyruvate carboxylase (PEPC) in the early stages of fruit development.

The application of potassium fulvic acid (PFA) is a promising strategy to alleviate the damage to plants and improve soil quality. However, the study of PFA on plant growth and rhizosphere microbial community remains limited.

Potassium fulvic acid is an organic fertilizer primarily composed of organic matter, nitrogen, phosphorus, potassium, and other nutrients. Its effects on the growth and development of citrus include the following:

1. Enhancing Soil Fertility: Rich in organic matter and trace elements, potassium fulvic acid improves soil structure, increases water and nutrient retention capacity, and boosts soil fertility.

2. Promoting Root Growth: It stimulates root development in citrus, enhances nutrient absorption efficiency, and strengthens the roots' ability to uptake essential elements.

3. Improving Fruit Quality: Potassium fulvic acid promotes sugar accumulation in citrus fruits, enhancing taste and quality. It also strengthens disease resistance, reducing the incidence of fruit infections.

4. Balancing Soil pH: It regulates soil acidity or alkalinity, optimizing conditions for citrus growth. In acidic soils, it raises pH levels, while in alkaline soils, it lowers pH to ideal ranges.

5. Boosting Stress Resistance: The compound improves citrus tolerance to adverse environmental conditions, such as drought, low temperatures, and saline-alkaline stress.

6. Facilitating Flower Bud Differentiation: It accelerates flower bud formation, enabling earlier blooming and increasing both yield and fruit quality.

7. Enhancing Photosynthesis Efficiency: By optimizing light energy utilization, potassium fulvic acid promotes photosynthesis, enabling citrus to synthesize more organic compounds for growth.

8. Accelerating Growth and Development: It supports nutrient absorption, speeds up growth rates, and ensures timely maturation of citrus plants.

9. Strengthening Immunity: The compound enhances the plant’s immune response, reducing susceptibility to pests and diseases.

10. Increasing Yield and Quality: Through these combined effects, potassium fulvic acid significantly improves citrus productivity and market competitiveness.

Potassium fulvic acid plays a multifaceted role in citrus cultivation. It enriches soil fertility, promotes root and fruit development, balances soil pH, enhances stress resistance, supports flowering, optimizes photosynthesis, accelerates growth, strengthens immunity, and ultimately improves yield and quality. As such, its use as an organic fertilizer is critical for sustainable citrus production and horticultural success.
