1、Optimizing nitrogen, phosphorus, and potassium fertilization regimes to

We hypothesized that a reasonable N, P, and K fertilizer application regimes under DRFM could improve maize yield and resources utilization efficiencies.

2、Fertilization with Phosphorus, Potassium, and Other Nutrients

When applied as fertilizer, both nutrients are quickly fixed in the soil solid fraction, mainly by adsorption or precipitation. Thus, in contrast to N, leaching risk is usually negligible, except in soils with very low adsorption capacity (e.g., very sandy soils).

3、Effect of Phosphorus and Potassium Fertilizers Application on Soil

At Assosa, a field experiment was conducted to determine how soil chemical characteristics and accumulation of phosphorus and potassium in potato tissue responded to phosphorus and potassium fertilizers application.

Using Phosphorus and Potassium Fertilizers Wisely

Phosphorus (P) and potassium (K) fertilizer prices have increased dramatically in recent months. If you cannot afford all the fertilizer P and K you think you need or there is not enough fertilizer to be had, you might want to prioritize their use on your farm.

Effects of phosphorus and potassium fertilizer application strategies

The method also increase the ratio of glutenin and gliadin, thereby improving the wet gluten content, hardness, and sedimentation value of the flour. With the same amount and method of fertilizer application, compound fertilizers are more effective than single-nutrient fertilizers.

Application Methods

There is little producers can do to change the basic soil and climatic characteristics that affect crop response to applied fertilizer. However, one can control phosphorus availability by managing the soil pH (acid soils), increasing organic matter, and by proper placement of phosphorus fertilizer.

The Best Practices for Applying Phosphorus and Potassium Fertilizers in

The timing and methods of applying potassium fertilizer in rice fields are critical factors for ensuring healthy growth and improving yield. Potassium plays a vital role in rice development, promoting root growth, enhancing disease resistance, and improving grain quality.

How to Add Phosphorus and Potassium to Soil?

This comprehensive guide will equip you with the knowledge to diagnose potential deficiencies, explore various methods for adding phosphorus and potassium, and make informed choices about the best amendments for your specific needs.

The application of phosphorus and potassium fertilizers is a critical practice in agricultural production to enhance crop yields and improve quality. These nutrients play vital roles in plant growth, promoting root development, strengthening stress resistance, enhancing crop quality, and increasing pest and disease resistance. Below are key methods for applying phosphorus and potassium fertilizers:

1. Select Suitable Fertilizers

Choose fertilizers based on soil texture, fertility, and crop requirements. Different types, such as diammonium phosphate or potassium sulfate, suit specific crops and soil conditions.

2. Application Methods

• Base Application: Evenly spread fertilizers over the tillage layer (approximately 20-30 cm deep) and incorporate them thoroughly via deep tillage.
• Topdressing: Apply additional fertilizers during critical growth stages (e.g., flowering or fruit enlargement) to support development.
• Foliar Spraying: For acid-loving crops like citrus, spray solutions like potassium dihydrogen phosphate directly onto leaves for nutrient supplementation.

3. Dosage

Adjust application rates according to soil fertility, crop needs, and fertilizer type. A general guideline is 5-10 kg of phosphorus and 5-10 kg of potassium per mu (approx. 0.067 hectares).

4. Timing

Apply fertilizers early morning or late evening when temperatures are cooler, reducing transpiration and improving absorption. Avoid immediate watering post-application to prevent nutrient loss.

5. Application Techniques

• Water-soluble fertilizers: Use drip or sprinkler irrigation.
• Granular fertilizers: Broadcast evenly.
• Avoid root contact: Prevent direct exposure to roots to minimize burn risks.

6. Post-application Management

Loosen soil, remove weeds, and regularly monitor soil pH and nutrient levels to refine future applications.

7. Precautions

• Avoid overapplication: Excessive use can disrupt nutrient balance and harm crops. Follow "small doses, frequent applications" principles.
• Combine with other fertilizers: Pairing phosphorus/potassium with nitrogen or organic fertilizers optimizes nutrient uptake and crop health.

scientific application of phosphorus and potassium fertilizers, paired with proper management, maximizes efficiency and supports sustainable agricultural development.
