1、Efficiency of Foliar Versus Granular Fertilization: A Field Study of Creeping Bentgrass Performance: Journal of Plant Nutrition: Vol 31 , No 5

Generally, turfgrasses are fertilized: (1) through soil nutrition which targets root uptake; (2) through liquid fertilization which targets foliar and/or root uptake; or (3) with both methods. Plan...

2、Comparative Effects of Nitrogen Fertigation and Granular Fertilizer Application on Growth and Availability of Soil Nitrogen during Establishment of Highbush

Early results indicate that fertigation may be less efficient (i.e., less plant growth per unit of N applied) at lower N rates than granular fertilizer application but is also safer (i.e., less plant death) and promotes more growth when high amounts of N fertilizer is applied.

3、Substrates and fertilizers for organic container production of herbs, vegetables, and herbaceous ornamental plants grown in greenhouses in

These fertilizers will typically last for four to five weeks, and are often supplemented with liquid fertilizers for longer-term crops or species with high nitrogen requirements. Liquid fertilizers also tend to be more quickly plant available compared to substrate-incorporated fertilizers.

4、Urea Finishing Process: Prilling Versus Granulation

Although the chemical properties of both prills and granules remain similar, their different physical and mechanical properties are distinguishable and make them suitable for different application either as fertilizer or raw materials for chemical industry.

Agronomic effectiveness of a granular poultry litter

OMF is an effective substitute to conventional phosphate fertilizers. Production of organomineral phosphate fertilizers (OMF) from poultry litter (PL) has been suggested to reduce the dependence on phosphorus (P) reserves.

Bioorganic fertilizer maintains a more stable soil microbiome than chemical fertilizer for monocropping

In this study, we hypothesized that reducing chemical fertilizer inputs supplemented with organic or bioorganic fertilizer can maintain the composition of soil microbiome more sustainable than the conventional method based on heavy fertilizer application in a monocropping system.

The comparative effects of ammonium nitrate, urea or a combined ammonium nitrate/urea granular fertilizer on the efficiency of nitrogen recovery

The comparative effects of ammonium nitrate (AN), urea or a combined 1:1 (w/w) AN/urea granular fertilizer with two different fillers (CaCO 3 or silica) were investigated on the efficiency of dry matter production and 15 N recovery by perennial ryegrass grown in pots under controlled environmental conditions.

Effect of different organic fertilizers application on growth and environmental risk of nitrate under a vegetable field

Organic fertilizers have been proposed as one solution to relieve environmental pressure and be a carbon-neutral alternative to liquid fossil fertilizers 16. Organic matter improves soil...

Agronomic Effectiveness of Zinc Sources as Micronutrient Fertilizer

Cogranulating Zn with phosphorus fertilizers can reduce effectiveness due to formation of insoluble Zn phosphates, but various technologies are becoming available to circumvent this issue. The application of foliar Zn sprays should be considered when plants are grown in Zn-sufficient soils and the main goal is food biofortification. 1. Introduction

Interactions between nitrate and ammonium in their uptake, allocation, assimilation, and signaling in plants

Mixtures of nitrate and ammonium are beneficial in terms of plant growth, as compared to nitrate or ammonium alone, and therefore synergistic responses to both N sources are predicted at different steps ranging from acquisition to assimilation.

Both liquid fertilizer and granular fertilizer are nutritional supplements used to support plant growth, each with distinct characteristics and suitable applications. Below is a detailed comparison of the two:

I. Composition Differences

1. Liquid Fertilizer:

   • Form: Liquid, typically water-based, containing essential nutrients like nitrogen (N), phosphorus (P), and potassium (K).
   • Formulation: Tailored to specific plant needs, often including microelements, vitamins, and other additives.
   • Convenience: Can be directly applied to roots via drip irrigation or diluted for foliar spraying.

2. Granular Fertilizer:

   • Form: Solid, available as powders or granules, requiring dilution in water before use.
   • Nutrient Distribution: Evenly concentrated nutrients, reducing leaching risks.
   • Application Flexibility: Can be broadcast on soil, dissolved for irrigation, or buried directly.

II. Fertility Performance

1. Liquid Fertilizer:

   • Fast Absorption: Rapid uptake due to liquid form, yielding quick results.
   • Targeted Application: Customizable formulas for precise nutrient delivery.
   • Environmental Impact: Easier to control dosage, minimizing runoff and pollution.

2. Granular Fertilizer:

   • Slow Release: Gradual nutrient release prolongs effectiveness and reduces waste.
   • Versatility: Suitable for diverse soils and plants, especially deep-rooted species.
   • Ease of Use: Simple to apply, even in dry form, with adjustable quantities.

III. Suitable Scenarios

1. Liquid Fertilizer:

   • Potted Plants: Ideal for small pots or indoor foliage plants due to efficient root penetration.
   • Specialty Plants: Beneficial for species requiring specific pH conditions (e.g., acid-loving flowers).
   • Growth Surge: Optimal during peak growth phases for rapid nutrient replenishment.

2. Granular Fertilizer:

   • Large-Scale Cultivation: Preferred for fields, lawns, or gardens due to bulk application.
   • Long-Term Fertility: Suitable for extended-release needs, reducing frequency of application.
   • Soil Enhancement: Organic-rich granular options improve soil structure over time.

IV. Economic Analysis

1. Liquid Fertilizer:

   • Higher Costs: Expensive production, packaging, and transportation increase prices.
   • Price Volatility: Market demand fluctuations lead to unstable pricing.
   • Storage Challenges: Prone to spoilage, requiring careful storage conditions.

2. Granular Fertilizer:

   • Cost-Effective: Lower production costs result in affordable pricing.
   • Stability: Long shelf life with minimal degradation risks.
   • Eco-Friendliness: Reduces chemical runoff compared to improper liquid applications.

Liquid and granular fertilizers each have advantages and limitations. The choice depends on specific needs, plant types, and budget constraints. In modern agriculture, combining both types often yields the best results, balancing efficiency, sustainability, and cost-effectiveness.
