1、Effects of foliar spraying of potassium fertilizer on the contents of

The objective of this study was to investigate the effects of foliar application of potassium fertilizer (KFA) applied to the leaves of wheat plants at the late-growth stage on the contents of microelements, phytic acid, the molar ratio of phytic acid to micronutrients and high-molecular-weight glutenin subunits (HMW-GS) in different types of ...

2、Effects of foliar spraying potassium

To improve the seed yield, foliar spraying of potassium fertilizer was studied to explore the effect of potassium-containing organic water-soluble fertilizer on rapeseed growth and yield.

3、Effects of the Foliar Application of Potassium Fertilizer on the Grain

Foliar fertilization has many advantages over soil fertilization and can compensate for a lack of soil fertilization. As a supplementary means of basic fertilization, foliar spraying can improve crop nutrient absorption and transformation efficiency, which is often recommended in production.

4、Effects of Foliar Fertilization: a Review of Current Status and Future

Foliar fertilizer application after soil fertilization is an effective method to increase the contents of trace elements in crops and crop yield, and to improve the soil environment. However, the application of inorganic foliar fertilizer results in difficulties in nutrient absorption and migration in plants.

Foliar fertilizer spraying technology and issues that need attention

Therefore, foliar fertilization cannot completely replace root fertilization of crops and must be combined with root fertilization. The amount of foliar fertilizer applied is small, the effect is rapid and obvious, and the utilization rate of fertilizer is improved.

Effects of Foliar Fertilization: a Review of Current Status and Future

Foliar fertilizer application after soil fertilization is an effective method to increase the contents of trace elements in crops and crop yield, and to improve the soil environment. However, the application of inorganic foliar fertilizer results in difficulties in nutrient absorption and migration in plants.

The effect of foliar application of different potassium fertilizers on

According to the research findings, potassium nitrate fertilizer had a significant impact on growth parameters in both years. The applications of potassium thiosulfate and potassium phosphite had comparable effects on growth and development.

The effect of foliar application of different potassium fertilizers on

Reasonable fertilization can improve soil fertility and leaf physiological traits, while excessive fertilization has negative effects on soil fertility, leaf physiology and yield. This study...

Effects of foliar

It is employed to improve the transportation and distribution of grape photosynthetic products, but the mechanism of its effect on fruit flavonoid synthesis is unclear.

Foliar spraying of potassium sulfate during fruit development

In this study, three different potassium fertilizers and one water (F1: 0.65% KNO 3, F2: 0.88% KH 2 PO 4, F3: 0.56% K 2 SO 4, and F4: water) were sprayed on Citrus reticulata cv. Nanfeng at cell division, cell expansion, fruit ripening, and throughout fruit developmental stages, respectively.

The effects of foliar spraying potassium fertilizer on vegetables are primarily manifested in the following aspects:

1. Promoting Growth and Development: Potassium fertilizer accelerates cell division and elongation, enhancing growth rates and yield. In vegetable production, appropriate application improves plant vigor, increases leaf area, and boosts photosynthetic efficiency, thereby elevating both productivity and quality.

2. Enhancing Stress Resistance: Potassium strengthens disease resistance by reducing pathogen incidence. It regulates metabolic processes (e.g., nitrogen and carbon metabolism) to maintain ion balance and enzyme activity, improving resilience against drought, cold, salinity, and other stresses. This also suppresses pest and disease outbreaks.

3. Improving Quality: Potassium enhances taste, nutritional value, and marketability. By optimizing metabolic pathways (e.g., sugar synthesis and protein formation), it reduces disease risks while promoting nutrient accumulation, enriching vitamins, minerals, and other health-promoting compounds.

4. Boosting Fruit Development: Potassium stimulates fruit enlargement, yield, and appearance. It aids carbohydrate and protein synthesis, ensuring even nutrient distribution for plump, vibrant, and flavorful produce.

5. Balancing Soil pH: Potassium adjusts soil acidity/alkalinity and improves fertility. As potassium salts interact with soil ions, they optimize pH, enhance soil structure, water retention, and nutrient availability, creating an ideal growth environment.

6. Strengthening Root Systems: Potassium fosters robust root development by regulating metabolic processes (e.g., nitrogen and phosphorus uptake). This improves water/nutrient absorption, root branching, and overall plant vitality.

7. Optimizing Fertilizer Use: Potassium maximizes nutrient utilization efficiency, reducing waste. By synergizing with nitrogen and phosphorus uptake, it lowers fertilizer requirements, cutting costs while minimizing environmental impact.

foliar potassium application accelerates growth, strengthens stress defenses, enhances quality/yield, improves soil health, promotes root vigor, and boosts fertilizer efficacy. Thus, judicious potassium use is indispensable for sustainable vegetable production.
