1、The effects of potassium fertilization on water‐use efficiency in crop plants

The main objective of this conceptual review is to confirm that adequate K management can be used as an important tool to alleviate the negative effects of water deficit on plant growth, yield-component formation, and yield.

2、Mixing Manure with Chemical Fertilizers, Why?and What is After?

Using chemical fertilizers or organic manure alone as amendments may bring negative effects to the quality of crops. Neither of these alone can sustain productivity. Hence, judicious uses of organic manure with chemical fertilizers are essential to augment productivity of crops.

3、Roles of nitrogen, phosphorus, and potassium fertilizers in carbon sequestration in a Chinese agricultural ecosystem

To enhance cereal production and meet the escalating food demands of the increasingly affluent population in China, the application of nitrogen (N), phosphorus (P), and potassium (K) fertilizers to agricultural soils has risen significantly.

Extrapolations on the Use of Rhizobium Inoculants Supplemented with Phosphorus (P) and Potassium (K) on Growth and Nutrition of Legumes

Nitrogen, phosphorus and potas-sium are among the most limiting nutrients for plant growth as they play different but crucial roles in the plant physiological processes. These macronutrients are fundamental components of cell building blocks including genes and chromosomes.

Effects of Potassium Fertilizer on Water

The objective of this study was to examine the effects of potassium fertilizer (standard (S) and high (H) levels) on water-soluble carbohydrate (WSC) content of timothy (Phleum pratense L.), si-lage fermentation, nutritive values, and nutrient intake.

Legumes, the seeds of leguminous plants, are a staple food in many countries. During their growth, legumes require sufficient nutrients, especially potassium, as it significantly impacts their development, yield, and quality. Potassium fertilizers promote stem and leaf growth, enhance stress resistance, and improve pod production and quality.

Basic Principles of Watering Legumes

1. Soil Moisture: Legumes prefer moist conditions but cannot tolerate waterlogging. Water only when the topsoil dries out.
2. Drainage: Proper drainage is critical to prevent root rot. Excess water should be promptly cleared to avoid prolonged standing water.
3. Uniform Watering: Avoid watering only near growth points, which may cause localized drought or overhydration. Ensure even watering across the entire planting area.
4. Avoid High-Temperature Periods: Watering during hot midday hours (typically noon) accelerates evaporation and reduces soil temperature, hindering root absorption.

Correct Watering Methods

1. Check Soil Moisture: Insert a finger 1–2 cm into the soil. If it feels dry, water is needed.
2. Water Quantity: Adjust based on weather and soil type. Avoid overwatering to prevent stagnation.
3. Irrigation Methods: For potted legumes, use drip irrigation or sprayers to control water volume and timing.
4. Watering Frequency: During the growing season (late spring to early autumn), water daily or every other day depending on climate and soil moisture.
5. Maintain Slight Moisture at Night: Nighttime watering helps stabilize soil temperature and boosts root activity.
6. Avoid Excessive Fertilization: Over-fertilization dilutes soil salinity, damaging roots and impairing water/nutrient uptake.

Using High-Potassium Fertilizers for Legumes

Potassium fertilizers strengthen disease resistance, energize plants, and enhance fruit quality. Options include synthetic fertilizers like potassium sulfate or potassium chloride, or natural sources like wood ash or sepiolite.

1. Timing: Apply before and during flowering to promote bud differentiation and fruit development.
2. Application Method: Evenly spread high-potassium fertilizers on soil, then water lightly to aid absorption.
3. Dosage: Adjust based on growth stage and soil fertility. Typically, apply 10–20 kg per mu (0.067 hectares).
4. Avoid Overdosing: Excess potassium disrupts nutrient balance and hampers absorption of other elements.
5. Balanced Nutrients: Combine with nitrogen and phosphorus fertilizers for optimal results.

Key Considerations

1. Soil Testing: Conduct tests to check pH, organic matter, and nutrient levels before fertilization.
2. Pest Control: Use pesticides or biological controls alongside fertilization.
3. Environmental Factors: Adjust watering/fertilization strategies based on weather changes.
4. Soil Improvement: Potassium-rich fertilizers enhance soil structure, water retention, and aeration, benefiting legume health.

legumes can thrive with high-potassium fertilizers if watering and fertilization practices align with proper timing and methods, ensuring healthy growth and high-quality yields.
