1、Effects of Different Types of Potassium Fertilizers on Nutrient Uptake

Specifically, four types of K fertilizers (complex fertilizer, potassium nitrate, potassium sulfate, and potassium dihydrogen phosphate) were applied to grapevines grown in plastic pots, and then their effects on grape growth and nutrient uptake were explored.

2、Effect of different foliar potassium fertilization forms on vegetative

Kaki cultivar ' Costata' suffers from potassium (K) deficiency especially it is growing in sandy soil, which results in decreased production. In the current study, we estimated the different foliar potassium fertilization forms (KCl, K 2 SO 4, and potassium nanoparticles: K-NPs).

3、(PDF) Potassium Nutrition of Fruit Crops

Potassium (K) nutrition is of paramount importance in fruit crops because of its profound influence on appearance, colour, soluble solids, acidity, taste, vitamin contents, and shelf-life of...

4、Foliar Nourishment with Different Potassium Sources to

Methods: Two field experiments were carried out in two seasons (2021 and 2022) to explore the response of lemon (Baladi cv.) trees grown in K-deficient soil to four different K fertilizer sources applied individually as a foliar spray.

How to Fertilize Fruit Trees Properly for Optimal Growth and Bountiful

Unlock the secrets to thriving fruit trees with our comprehensive guide on proper fertilization techniques. Discover essential nutrient needs, from nitrogen to potassium, and learn how to tailor your approach based on tree type and soil quality.

Effects of Foliar Potassium Fertilization on Fruit Growth Rate

Except the first year of study, foliar application of K fertilizers generally led to an increase in the concentration of fruit total soluble sugar, titratable acidity (TA) and sweetness, along with an elevated K accumulation in leaf and fruit at maturity.

When & How to Fertilize Fruit Trees: Complete Guide

Spring is generally considered the ideal time to fertilize fruit trees. As the trees begin to exit from dormancy and enter their active growth phase, they require a boost of nutrients to support healthy development and abundant fruit production.

Which Fertilizer for Fruit Trees: A Complete Guide to Boosting Health

Discover the key to thriving fruit trees with our comprehensive guide on selecting the right fertilizer. Uncover vital nutrients like nitrogen, phosphorus, and potassium while learning to identify signs of deficiencies that hinder growth.

Optimizing phosphorus and potassium input based on phosphorus and

Phosphorus (P) and potassium (K) are two essential macronutrients for plant growth and development.

Effect of potassium fertilization during fruit development on tomato

Deficit irrigation and increasing K fertilization significantly improved fruit quality. Sufficient water supply during fruit development is essential to improve plant WUE. K fertilization during fruit development promoted K uptake, while decreased KUE.

Potassium fertilization methods for fruit trees primarily include the following categories:

1. Basal Application Method

This method involves spreading potassium fertilizer directly onto the soil surface, followed by deep tillage to incorporate it into the soil. Suitable for soils with high inherent potassium content, basal application enhances soil potassium levels, promoting tree growth and development. It can be applied in strip, ring, or broadcast patterns to optimize fertilization effects.

2. Pitting Method

Pitting involves digging several small holes within the root distribution area of the tree, applying potassium fertilizer into the holes, and backfilling the soil. This reduces nutrient loss and improves fertilizer efficiency. It is ideal for older trees with deeper root systems, such as apples, pears, and peaches.

3. Trench Application Method

Trench application requires digging shallow trenches between tree rows or individual plants, spreading potassium fertilizer into the trenches, and covering them with soil. This minimizes nutrient runoff and boosts efficiency. It works well for younger trees with shallower roots, like grapes and cherries.

4. Foliar Spraying Method

Foliar spraying involves dissolving potassium fertilizer in water and spraying it directly onto tree leaves using a foliar sprayer. This allows rapid absorption of potassium by the plant, maximizing utilization. It is suitable for young, vigorously growing trees, such as strawberries and blueberries.

5. Drip Irrigation Method

Drip irrigation delivers potassium fertilizer dissolved in water through a drip system directly to the soil near the tree roots. This method enables precise fertilization, reducing waste and improving efficiency. It is effective for young, fast-growing trees like strawberries and blueberries.

6. Combined Application of Organic Fertilizer and Potassium

This approach mixes organic fertilizers with potassium fertilizers before application. It enhances nutrient uptake, lowers costs, and suits all fruit tree types. the choice of organic materials should align with soil properties and tree nutritional needs.

7. Mixed Application with Microelements

Combining potassium fertilizers with micronutrients (e.g., calcium, magnesium, zinc) addresses multiple nutritional demands, strengthening disease resistance and fruit quality. This method applies to various trees but requires tailored micronutrient selection based on specific requirements.

There is no one-size-fits-all approach to potassium fertilization for fruit trees. The optimal method depends on tree species, growth stage, soil conditions, and other factors. Practitioners should also balance potassium with other essential nutrients to ensure comprehensive tree health.
