1、How Much Potassium Fertilizer Is Appropriate for One Mu of Rice?

1、Fertilizer Management in Rice Abstract The increasing trend in the production of rice will have to be continued to meet the requirements of the projected global population. Fertilizer use is one of the major factors for the continuous increase in rice production since the Green Revolution era.

2、AGROOMY Potassium Recommendations

Once the removal rate is known, use the following formula to calculate how much potassium fertilizer should be added to replenish the soil’s potassium reserves.

3、Strategies for fertilizer management to achieve higher yields and

Data collection For construct an adjustable rice production model to obtain higher yields and fertilizer productivity while lowering GHG emissions in midseason rice systems, soil traits and fertilizer input rates or regimes were selected, but meteorological data were not selected because they cannot be adjusted or modulated under field conditions.

4、Estimating thresholds of nitrogen, phosphorus and potassium fertilizer

Abstract Determining the fertilization rate plays a pivotal role in agronomic practices as they directly impact yield targets, soil fertility, and environmental risks. In this study, we proposed a method that utilizes allowed ranges of partial nutrient balance and yield to estimate the threshold of nitrogen (N), phosphorus (P), and potassium (K) fertilizer applied to rice (Oryza sativa L ...

What fertilizer is used for wheat base fertilizer? How much is used per

After understanding the above contents, we can know that when sowing wheat, the base fertilizer can be ternary compound fertilizer (such as nitrogen, phosphorus and potassium content of 15 respectively), or diammonium and potassium fertilizer can be used together.

Potassium Fertilizers for Crop Production

Potassium is one of three macronutrients essential for plant growth. Learn which fertilizers have high potassium and how to measure and apply it for agriculture production.

Effective potassium management for sustainable crop production based on

In words, for soils initially rich in K, a sustainable K management strategy should consider adjusting K apparent balances based on K fertilizer prices. In contrast, for soils naturally deficient in K, enhancing soil K fertility through K fertilization is essential, alongside the strategic use of straw.

How To Apply Potassium Nitrate Fertilizer: A Step

Learn how to boost your plant's growth and productivity with potassium nitrate fertilizer. This step-by-step guide includes everything you need to know, from nitrogen and potassium content to application instructions.

How to apply base fertilizer for better results?

Generally, about 30% of the total amount of nitrogen fertilizer used on high fertility soil is used as base fertilizer, while 50% to 70% of nitrogen fertilizer is used as base fertilizer on medium and low fertility soil, and phosphorus, potassium, and trace fertilizers should be used as all at once as much as possible.

How Much Potash Fertilizer to Use? The Right Amount For Your Garden

Potassium, the key nutrient provided by potash, plays a vital role in numerous physiological processes, from photosynthesis and enzyme activation to water regulation and disease resistance. Understanding how much potash fertilizer to use is crucial for maximizing crop productivity while minimizing environmental impact.

Applying base fertilizer is a critical step to ensure healthy crop growth and increase yields when planting rice. Potassium fertilizer, as an essential nutrient, plays a vital role in rice development. Below is a detailed guide on the appropriate amount of potassium fertilizer for one mu of rice fields, along with its functions, selection criteria, application methods, precautions, and recommended dosages.

1. The Role and Importance of Potassium Fertilizer

Potassium performs multiple crucial physiological functions in plants. First, it promotes root development, enhances soil water retention, and reduces moisture loss. Second, it helps regulate water balance within plants, significantly improving stress resistance. Additionally, potassium stimulates protein synthesis, boosting crop yields. For rice, adequate potassium fertilization improves grain quality and increases per-unit output.

2. Choosing the Right Type of Potassium Fertilizer

The selection of potassium fertilizer depends on the rice growth stage and soil conditions. Common types include potassium sulfate, potassium chloride, and potassium nitrate. Potassium sulfate is widely used due to its affordability and ease of absorption. different fertilizers vary in nutrient content and release rates, so adjustments should be made based on specific needs.

3. Determining the Appropriate Dosage

The amount of potassium fertilizer required depends on soil texture, pH, and rice growth stages. Generally, 5–10 kg of potassium sulfate per mu is recommended for base fertilization. This range suits most rice fields, but local adjustments may be necessary.

4. Application Methods for Potassium Fertilizer

Potassium can be applied as base fertilizer (incorporated into soil before planting) or topdressing fertilizer (added during growth). Ensure even distribution to avoid over- or under-application, which could harm crop development.

5. Precautions and Recommendations

• Avoid mixing with nitrogen fertilizers to prevent excessive nitrogen.
• Do not apply after heading, as this may delay grain maturation.
• Follow the "small amounts, frequent applications" principle to prevent soil salinization.

The optimal potassium dosage for one mu of rice fields varies by region, soil conditions, and growth stages. Flexible adjustments ensure healthy rice growth and high yields. Proper use of potassium fertilizer not only improves grain quality but also enhances land efficiency, supporting sustainable agricultural development.
