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

Potassium (K) has a considerable effect on wheat quality, and prudent application of K fertilizer can significantly improve wheat yield and quality.

2、How to reasonably apply potassium fulvic acid for soil compaction plots

Mineral humic acid flushing fertilizer is suitable for flushing, with a dosage of about 300 to 500 grams per mu, and can reduce the dosage of large chemical fertilizers by 20% to 30%. In addition, humic acid also has the effect of alleviating soil salinization.

3、Fulvic Acid and Potassium Application to Mitigate Drought Effects on

Two field experiments were conducted during the summer seasons of 2023 and 2024, using the sweet potato cultivar Aibs. Six treatments were applied in a randomized complete block design with three replicates.

What should you pay attention to when spraying wheat foliar fertilizer?

According to the experiment, the spraying of wheat from the booting stage to the heading stage can significantly extend the functional period of the leaves and increase the grain yield, which is the best period for spraying fertilizer.

Effects of the Foliar Application of Potassium Fertilizer on the Grain

In the late growth stage of wheat, potassium deficiency occurs even under sufficient nitrogen/phosphorus (N/P) levels, so it is necessary to supplement potassium through foliar spraying.

Spraying foliar fertilizer for high yield of growing wheat

Spraying foliar fertilizer from flowering to filling stage can effectively improve yield and quality. 1. Spray method 1. Spray 99.5% multidimensional potassium dihydrogen phosphate with 100 grams of multidimensional potassium dihydrogen phosphate per mu and spray evenly with 30 kilograms of water.

Chasing the Biggest Bang

The best choice is to foliar spray 8 kgs of potassium sulphate per hectare in a minimum 100 litres of water with 250 grams of Soluble Fulvic Acid powder. This provides a substantial K-kick, while also supplying much needed sulphur, to boost protein levels.

How fulvic acid can cut glyphosate rates and improve foliar N

“Foliar urea with fulvic acid is three times more effective than granular fertiliser – 10kg N/ha of urea and fulvic acid is the equivalent of 30kg granular N/ha,” he says.

How to Formulate Liquid Fertilizers with Potassium Fulvate: A Complete

In this guide, we’ll walk you through all the key considerations and best practices to help you formulate potassium fulvate-based liquid fertilizers like a pro. 1. Choose the Right Potassium Fulvate Raw Material. The first and most important step is raw material selection. Not all potassium fulvates are created equal.

Potassium fulvic acid is an organic fertilizer containing various organic acids and minerals. It improves soil structure, enhances soil fertility, and promotes crop growth. When applying potassium fulvic acid to wheat via foliar spraying, the specific dosage should be determined based on soil conditions, crop requirements, and the concentration of the product.

I. Functions of Potassium Fulvic Acid

1. Enhances Soil Fertility: The organic acids and minerals in potassium fulvic acid form chelates with nutrients in the soil, improving nutrient availability.
2. Improves Soil Structure: It increases microbial activity, accelerates decomposition of organic matter, and enhances soil aeration and water-retaining capacity.
3. Promotes Crop Growth: Stimulates root development, boosts nutrient absorption, and accelerates crop growth.

II. Dosage for Wheat Foliar Spraying

1. Based on Soil Conditions:

   • For soils with low organic matter, apply a moderate amount; for soils rich in organic matter, reduce the dosage. Generally, 5-10 kilograms per mu is recommended.

2. Based on Crop Demand:

   • For vigorously growing crops requiring high nutrients, increase the dosage; for slower-growing crops, reduce it. The standard remains 5-10 kilograms per mu.

3. Based on Concentration:

   • Higher concentrations yield better results but may lead to salt accumulation. Adjust the concentration according to soil and crop needs. The typical dosage is 5-10 kilograms per mu.

III. Application Method

1. Dissolve potassium fulvic acid in water to prepare the solution.
2. Uniformly spray the solution onto wheat stems and leaves.
3. Irrigate promptly after spraying to aid absorption and utilization.

IV. Precautions

1. Monitor crop growth closely and adjust dosage if abnormalities arise.
2. Avoid mixing with other fertilizers to prevent chemical reactions that reduce efficacy.
3. Do not overapply to avoid soil salinization, which harms crops.
4. Minimize environmental impact and prevent pollution.

The optimal dosage of potassium fulvic acid for wheat foliar spraying is 5-10 kilograms per mu, adjusted according to soil, crop, and concentration factors. Regularly observe crop responses, avoid excess use, and prioritize environmental safety.
