However, in acidic soil, it is not clear how long-term application of lime and nitrogen (N)-based fertilizer affects soil chemical properties, the wheat and maize grain yields (GY), and N-use efficiency (NUE).

FERTILIZER NUTRIENT SOURCES AND LIME

Hydroxide limes, also known as slaked lime, hydrated lime or build-er’s lime, react similarly to oxides in the soil and are also powdery and unpleasant to handle.

Fertilizer & Lime for Beginners

Applying this concept, a 50 pound bag of 10-20-20 fertilizer would contain 5 pounds of nitrogen, 10 pounds of phosphate and 10 pounds of potassium. The other 25 pounds of material in the bag of fertilizer is filling material.

Nitrogen and fertilisers

The lime reacts with the water in the soil to form slaked lime (Ca(OH)2). The stronger alkali displaces ammonia from the ammonium salts. Since ammonia gas escapes from the soil and is lost by it.

Fertilizer Mixtures: Principles, Types and Advantages

Quick lime, slaked lime, potassium carbonate, basic slag and cynamide, which are basic in nature, should not therefore, be mixed with ammonical fertilizers and organic manures.

Understanding the Big Three: Nitrogen, Phosphorus, and Potassium

Understanding the “Big Three” nutrients – Nitrogen, Phosphorus, and Potassium (NPK) – is essential for effective fertilizer management in agriculture. These primary macronutrients play a crucial role in plant growth and development. Here’s a deeper look at each of them:

Limestone and slaked lime influence physical and chemical modelling on

Abstract A binary systems' components mutual influence thermodynamic assessment containing limestone or slaked lime in a mixture with nitrogen-containing, potassium-containing and phosphorus-containing mineral fertilizers has been carried out.

The Benefits of Lime and Fertilizer

The most common pasture amendments include lime, nitrogen, phosphorus, and potassium. A lime application will raise the soil pH. A pH in the range of 6.2 to 6.8 maximizes the ability of the grass to access nutrients in the soil. Within this range, soil microbes are most active.

Slaked lime (calcium hydroxide) is a common chemical fertilizer primarily used to improve soil structure, enhance soil fertility, and promote crop growth. Compared to the three major types of chemical fertilizers, slaked lime plays a unique role in agricultural production. Below is a detailed explanation of the differences between slaked lime and nitrogen, potassium, and phosphorus fertilizers.

1. Nitrogen Fertilizers

Nitrogen fertilizers are among the most critical fertilizers in agriculture, providing plants with essential nitrogen for growth. They are divided into organic and chemical types:

• Organic fertilizers: Include farm manure (e.g., animal dung) and green manure, which release nitrogen slowly.
• Chemical fertilizers: Synthetic compounds like urea and ammonium nitrate. Function: Promote stem and leaf growth, improve photosynthesis efficiency, and increase yield.

2. Potassium Fertilizers

Potassium fertilizers supply plants with essential potassium:

• Organic fertilizers: Include wood ash, seabird excrement, etc., which release potassium slowly.
• Chemical fertilizers: Synthetic compounds like potassium sulfate and potassium chloride. Function: Enhance root development, disease resistance, and fruit quality.

3. Phosphorus Fertilizers

Phosphorus fertilizers provide plants with essential phosphorus:

• Organic fertilizers: Include bone meal and fish meal, which release phosphorus slowly.
• Chemical fertilizers: Synthetic compounds like diammonium phosphate and superphosphate. Function: Stimulate root growth, strengthen disease resistance, and improve fruit quality.

4. Key Differences Between Slaked Lime and Other Fertilizers

(1) Application Method

• Slaked lime is applied in powdered or granular form, directly mixed into the soil.
• Nitrogen, potassium, and phosphorus fertilizers must be dissolved in water before use and require precise ratios and methods for application.

(2) Fertility Characteristics

• Slaked lime acts slowly but sustainably, providing long-term nutrients.
• Nitrogen, potassium, and phosphorus fertilizers act quickly but temporarily, requiring regular reapplication.

(3) Impact on Soil

• Slaked lime improves soil pH, creating optimal conditions for plant growth.
• Nitrogen, potassium, and phosphorus fertilizers may negatively impact soil (e.g., acidification, compaction) if overused. Careful dosage and application are critical.

(4) Cost-Effectiveness

• Slaked lime is low-cost and economical.
• Nitrogen, potassium, and phosphorus fertilizers are pricier and risk wastage if misused. Cost considerations are essential when selecting fertilizers.

(5) Crop Compatibility

• Slaked lime suits diverse crops, including grains, vegetables, and fruits.
• Nitrogen, potassium, and phosphorus fertilizers are often tailored to specific crops (e.g., rice, wheat, corn, cotton).

Slaked lime differs from nitrogen, potassium, and phosphorus fertilizers in application methods, fertility duration, soil impact, cost, and crop compatibility. In practical agriculture, farmers should choose fertilizers based on crop needs and soil conditions, applying them scientifically to maximize yield benefits.
