Efficient potassium management is essential to maximize crop yields while minimizing environmental impacts. This chapter explores strategies to enhance potassium use efficiency (KUE) in...

2、Effective potassium management for sustainable crop production based on

Potassium (K) is an essential macronutrient for sustainable crop production. The impact of exogenous K input on soil K apparent balance has been increasingly investigated; however, the effects of K input on K reserves and crop yields in soils with different characteristics are not well understood.

3、Fertilization with Phosphorus, Potassium, and Other Nutrients

P and K fertilizer management should minimize the transformation of applied nutrients to nonavailable forms and maximize crop absorption. To this end, banding or fertigation may be an alternative to broadcast applications.

4、Frontiers

We recommend that the optimum fertilization ratio of Sapindus mukorossi was 0.96Kg N, 0.80Kg P and 0.64Kg K per plant. Reasonable fertilization can improve soil fertility and leaf physiological traits, while excessive fertilization has negative effects on soil fertility, leaf physiology and yield.

5、Optimizing nitrogen, phosphorus, and potassium fertilization

However, little is known about reasonable application amounts of nitrogen (N), phosphorus (P), and potassium (K) fertilizers for maize under this planting pattern, and local farmers applying unreasonably large fertilizer amounts results in wasted resources and environmental pollution.

Optimizing Nitrogen, Phosphorus, and Potassium

To avoid the wasting of fertilizers and promote plant quality, the optimal application levels were calculated using a regression analysis. The suggested N, P, and K applications were 6.89 g/plant, 1.97 g/plant, and 3.33 g/plant, respectively.

How to Increase Potassium Fixation for Healthier Plants

Before diving into how to increase potassium fixation (or more accurately, how to reduce fixation and increase bioavailable potassium), it’s important to understand how vital potassium is for plant health:

Effect of Different Potassium Fertilizer Application Rates on

Potassium (K) is crucial for global maize (Zea mays L.) production, yet the issue of “high K fertilizer input but low utilization efficiency” in K-rich soils of Xinjiang remains underexplored. A three-year field experiment (2020, 2021, 2024) in Xinjiang evaluated the effects of reduced K application on maize growth, grain yield (GY), and K-use efficiency. Five treatments were tested: K100 ...

Potassium Fertilization in the Production of Vegetables and Fruits

The horticulturist should prioritize the use of potassic fertilizers with lower salt content, if possible free of chlorine and containing magnesium and sulfur. However, it is essential to remember that the high potassium content in plants can induce deficiency of calcium and magnesium.

High-potassium vegetables, such as spinach, celery, and tomatoes, are rich in potassium, which plays a critical role in human health. Potassium is an essential macronutrient for the human body, vital for maintaining heart function, regulating blood pressure, promoting muscle contraction, and nerve conduction. proper fertilization during cultivation is crucial. Below are detailed strategies to enhance the effectiveness of potassium fertilization:

1. Select Appropriate Potassium Fertilizers: Potassium fertilizers come in various forms, including potassium sulfate, potassium nitrate, and potassium chloride. The choice depends on soil type, crop requirements, and climate. Generally, potassium sulfate and potassium nitrate are suitable for most crops, while potassium chloride is better for acidic soils.

2. Timing of Application: The timing of potassium fertilization affects its efficacy. Applying potassium during early growth stages (e.g., seedling period) improves absorption by crops. In later stages (e.g., flowering and fruiting), it enhances fruit quality and yield.

3. Optimal Dosage: Proper dosage is key. Excessive potassium can lead to excessive vegetative growth, reducing quality, while insufficient doses may limit yields. Adjust dosages based on soil fertility, crop needs, and climate.

4. Application Methods: Foliar spraying is an effective method to boost potassium content in crops. Alternative approaches include basal fertilization, topdressing, and root-zone drenching.

5. Combine with Other Fertilizers: Pairing potassium with nitrogen or phosphorus fertilizers improves efficiency. For example, combining with nitrogen enhances potassium uptake, while phosphorus promotes absorption of potassium.

6. Soil pH Considerations: Soil acidity impacts potassium availability. Acidic soils generally maximize potassium effectiveness, whereas alkaline soils may require pH adjustments to maintain fertilizer efficacy.

7. Avoid Continuous Cropping: Repeated planting of the same crop depletes soil potassium, reducing yields and quality. Rotate crops to sustain soil potassium levels and fertilizer effectiveness.

8. Regular Soil Nutrient Testing: Periodic soil tests help monitor nutrient status, guiding rational fertilization. They also enable timely detection of potassium deficiencies or excesses, allowing corrective actions.

Rational fertilization is key to maximizing yield and quality in high-potassium vegetables. Tailor potassium selection, dosage, application methods, and timing to soil conditions, crop needs, and climate. Additionally, avoid monocropping and conduct regular soil analyses to ensure optimal growth and nutrient balance.
