1、Effects of Fulvic Acid Potassium on Nutrient Absorption, Yield and

Different application rates of fulvic acid potassium were applied during the fruit expansion stage, with the conventional fertilization by farmers as the control, to analyze its influence on the absorption of nitrogen, phosphorus and potassium nutrients, as well as the yield and quality of apples.

2、Frontiers

Previous studies have determined that fulvic acid (FA) prevents plants from suffering from abiotic stress. However, little is known about the mechanisms for ...

3、Study On The Effect Of Potassium Fulvic Acid Fertilizer On Increasing

Potassium fulvic acid fertilizer is a hormone-like substance with high biological activity. The substance has significant effects in improving crop and vegetable yield, quality, disease resistance and other aspects. In this experiment, it was used to improve the fruit setting rate of apples and pears.

4、Essential Role of Potassium in Apple and Its Implications for

Consequently, the apple fruits affected by the K/Ca imbalance frequently develop physiological disorders in storage. This emphasizes the importance of the balanced K application, especially during the last months of the growing season, depending on the crop load and the actual K demand.

Effects of potassium fertilizer on endogenous hormone

The regulation mechanism of K on acid metabolism of 'Red Delicious' apple fruit was discussed through the determination and analysis of K accumulation, fruit quality, endogenous hormone content, organic acid content and acid metabolism related enzyme activities in different organs during its growth and development.

Effects of potassium fertilizer on endogenous hormone content and acid

The results showed that fruit weight, Vc content, soluble solids content and hardness increased with the increase of K application, but there was no significant difference between T4 and T3 (P < 0.05).

What is the Effect of Potassium Fulvic Acid on Apples?

Potassium fulvic acid (KFA) is an organic compound fertilizer primarily composed of fulvic acid and potassium salts. It is a new type of highly efficient compound fertilizer produced by reacting natural plant-derived fulvic acid with potassium chloride under high temperatures.

Effects of Fulvic Acid Potassium on Nutrient Absorption, Yield and

Different application rates of fulvic acid potassium were applied during the fruit expansion stage, with the conventional fertilization by farmers as the control, to analyze its influence on the absorption of nitrogen, phosphorus and potassium nutrients, as well as the yield and quality of apples.

Effects of Fulvic Acid on Growth and Nitrogen Utilization Efficiency in

Both fulvic acid (FA) and nitrogen (N) play important roles in agricultural production in China. Plants typically show a higher nitrogen utilization efficiency (NUE) under FA application. However, the role of FA application in apple growth and NUE remains unclear.

[Effects of different potassium fertilizer application periods on the

The results indicated that, compared with no potassium-applied treatment (CK), all potassium fertilizer application treatments significantly increased the apple yield by 4.3%-33.2%, meanwhile, it also obviously improved the fruit quality.

Potassium fulvic acid (KFA) is an organic compound fertilizer primarily composed of fulvic acid and potassium salts. It is a new type of highly efficient compound fertilizer produced by reacting natural plant-derived fulvic acid with potassium chloride under high temperatures. KFA offers multiple functions, including improving soil water and nutrient retention, promoting crop growth, and increasing yield.

1. Enhancing Soil Fertility: KFA is rich in organic matter and trace elements, effectively boosting soil fertility. It improves soil structure, increases air and water permeability, and loosens the soil, which benefits root growth. Additionally, KFA increases the population of beneficial microorganisms, enhances soil biological activity, and promotes plants’ absorption and utilization of nutrients.

2. Promoting Crop Growth: KFA stimulates plant growth and strengthens resistance to diseases and pests. It regulates nutrient balance within plants, enabling better absorption of nutrients and higher yields. KFA enhances photosynthetic efficiency and overall plant health.

3. Improving Crop Quality: Using KFA significantly enhances crop quality. It promotes the synthesis of proteins, fats, and other nutritional components, resulting in plumper fruits and better taste. Additionally, KFA strengthens antioxidant capacity, extends storage life, and adds value to agricultural products.

4. Reducing Chemical Fertilizer Use: KFA can substitute for part of chemical fertilizers, reducing agricultural costs. Its abundant organic matter and trace elements are readily absorbed by crops, minimizing reliance on synthetic fertilizers. This practice protects the environment, conserves resources, and supports sustainable development.

5. Eco-Friendly and Pollution-Free: KFA is a green fertilizer free from harmful substances, causing no environmental pollution. It degrades naturally in soil and is absorbed by plants, achieving resource recycling. Thus, using KFA aligns with eco-friendly and pollution-free farming practices.

6. Simple Application: KFA is easy to use. It can be applied directly to soil, mixed with chemical fertilizers, or adjusted based on crop needs and soil conditions for optimal results.

7. Wide Applicability: KFA is suitable for various crops, especially those struggling with poorly soluble fertilizers. It works well on cereals, cash crops, vegetables, fruit trees, and other plants.

KFA delivers remarkable results by improving soil fertility, promoting crop growth, enhancing yield and quality, reducing chemical fertilizer use, and being environmentally friendly. KFA is a highly efficient fertilizer worth promoting.
