1、The Right Time To Apply Phosphorus And Potassium

For farmers interested in strip-till this fall, Fernandez recommends waiting until at least the middle of October to avoid heavy rains that can flatten the berm created during the tillage operation. Applying phosphorus and potassium annually or biennially is debatable.

2、300: Fall vs. Spring: When Should You Apply K?

What if simply changing when you apply potassium could lead to higher yields and profitability? In this episode, digging into K applications. With rising costs and market uncertainty, now’s the time to make sure everything we do pencils out.

3、Effects of different sources of potassium fertiliser on yield, fruit

To determine the optimal potassium fertiliser for kiwifruit, this study investigated the effects of different potassium sources on kiwifruit yield and postharvest quality as well as plant and soil nutrient contents in an orchard in Shaanxi Province, Northwest China.

OPTIONS FOR SUPPLYING POTASSIUM TO KIWIFRUIT VINES

In supplying the 250 kg of potassium required by a productive hectare of kiwifruit, there are several options available in the form and timing of fertiliser applications. In this paper, soil and leaf analysis are emphasised in interpreting field trials using different means of supplying potassium.

Kiwifruit fertilizer and water management should be paid attention to

When watering after fertilization, apply bio-organic fertilizer or fungus with water, such as Leading You, EM, Bacillus subtilis, Mumei Tuli, Enyibi, etc., to slow down the adverse effects of chemical fertilizers on soil structure and fruit quality.

How to Fertilize Kiwi Plants: A Complete Guide to Nutrient Balance

Discover the ideal nutrient balance and application frequency while navigating the organic versus synthetic fertilizer dilemma. Master the art of timing, dosage calculations, symptom detection, and troubleshooting to cultivate healthy kiwi plants and prevent over-fertilization woes.

The Best Time to Apply Potassium Fertilizer for Lawns

However, applying potassium fertilizer at the right time is crucial to maximize its benefits and avoid wastage or lawn damage. This article explores the best time to apply potassium fertilizer for lawns and provides comprehensive insights into optimizing lawn health through potassium management.

Potassium Fertilizers

Time it right: Apply potassium before key growth stages like flowering or fruit set. Don’t overapply: Excess potassium can lock out calcium and magnesium, causing secondary deficiencies.

When to Apply Potash to Lawn (2026)

Once you know how much potassium to apply to your lawn, apply the potassium fertilizer evenly when the ground is dry. Check the weather to ensure there is no rain in the forecast for at least the next day after you fertilize because water can wash away your efforts.

Kiwifruit (Actinidia chinensis Planch.) is a highly nutritious fruit rich in vitamin C, dietary fiber, and microelements such as potassium. Potassium, an essential mineral for human health, plays a critical role in maintaining cardiac function, muscle activity, and neural signaling. Proper fertilization is vital to enhancing both the quality and yield of kiwifruit.

Optimal Timing for Potassium Fertilization

1. Spring Fertilization: Spring is a crucial growth phase for kiwifruit. Applying potassium during this period promotes new shoot development and flower bud differentiation, which improves fruit productivity and quality. Spring fertilization typically occurs from February to April, with timing adjusted based on local climate and soil conditions.

2. Autumn Fertilization: During autumn, when fruits expand and ripen, potassium application supports fruit development, increasing sugar content and taste. Autumn fertilization is recommended from September to October to ensure adequate nutrient reserves for the fruits.

Methods of Applying Potassium Fertilizer

1. Soil Application: Potassium sulfate fertilizer can be spread directly under the tree canopy or dissolved in water for uniform irrigation. Avoid direct contact with roots to prevent damage.

2. Foliar Application: A quick method to supplement potassium, foliar spraying involves applying diluted potassium sulfate solutions or mixtures of urea and potassium sulfate. This enhances potassium uptake during the growing season.

Key Considerations

1. Soil pH: Kiwifruit thrives in soils with a pH of 6.0–7.5. Adjust soil acidity or alkalinity if necessary to optimize potassium absorption.

2. Fertilizer Type: Select suitable potassium sources (e.g., potassium sulfate, nitrate, or chloride) based on soil properties and plant needs.

3. Application Rates: Spring doses should be slightly higher to support growth and bud differentiation, while autumn rates should focus on fruit maturation. Adjust according to soil fertility and plant stages.

4. Timing: Apply fertilizer during early growth and fruit expansion periods. Monitor plant health and fruit development to refine application strategies.

The best times for potassium application are spring and autumn. Spring fertilization boosts shoot growth and bud differentiation, while autumn applications enhance fruit quality. Choose appropriate fertilizers, application methods, and timing based on soil and plant requirements. Proper management of potassium fertilization improves kiwifruit yield and quality, delivering greater economic benefits for farmers.
