We summarized the current research carried out to modify the N content of grapes. Technical and scientific aspects are discussed for future research in this field. Nitrogen is a structural component of proteins, nucleic acids, chlorophyll, hormones and amino acids.

How to Fertilize Grape Plants

Excess nitrogen can lead to overly vigorous foliage growth at the expense of fruit quality, making grapes less sweet and more prone to disease. Apply nitrogen fertilizer in moderate amounts, preferably in split doses during the growing season—once in early spring and again after fruit set.

Insight into how fertilization strategies increase quality of grape (

Organic and bioorganic fertilizers were increasingly used for agricultural soil. However, little is known on what kind of organic fertilizer application strategies can promote grape production well and how appropriate fertilization strategies improve soil properties and shift microbial community.

This review covers the importance of organic fertilizer, macronutrients, and micronutrients applied to the grapevines for improving productivity and quality of grapes.

Grapes Fertilizer Management

First of all, you have to take into consideration the soil condition of your field through semiannual or annual soil and tissue testing before applying any fertilization method.

The Use of Grape Pomace as Soil Fertilizer: A Microcosm Study on

Grape pomace (GP) is used as a fertilizer in viticulture due to its carbon (C) and nitrogen (N) richness. Its application follows as biologically treated (i.e., vermicompost) or as untreated (fresh), with different nutritional inputs for the soil.

Pilot study analysis based on various fertilizers on grape cropping

Suppressive composts utilization is necessary to reduce agricultural waste and exhaust biomass from different bio-fuel chains. This paper introduces the advanced temperature and time agricultural bio-ethanol harvest method to increase the concentration of grape sugar levels.

Nitrogen-based compound fertilizer is a highly efficient agricultural product that contains three primary nutrients essential for plant growth: nitrogen (N), phosphorus (P), and potassium (K). It provides rapid nutrient uptake for plants. When using this fertilizer for grape cultivation, special attention must be paid to application methods to ensure healthy growth and high yields. Below is a detailed guide to fertilization:

I. Understanding the Characteristics of Nitrogen-Based Compound Fertilizer

1. Nutrient Composition:

   • This fertilizer contains nitrogen (N), phosphorus (P), and potassium (K), all critical for grape development.
   • Nitrogen promotes leaf growth, phosphorus enhances fruit quality, and potassium improves disease resistance and post-harvest storage capabilities.

2. Fertilizer Efficiency:

   • Nitrogen in this fertilizer is prone to volatilization, so it should be mixed with other fertilizers to improve utilization.
   • Phosphorus moves easily in soil, requiring deep application or combination with organic fertilizers to prevent loss.
   • Potassium is absorbed quickly by plants, but excessive use may cause root burn.

II. Optimal Timing for Fertilization

1. Spring:

   • Apply fertilizer before bud break to promote root development and nutrient accumulation, supporting new shoot and flower formation.

2. Summer:

   • Fertilize during or after peak temperatures to aid fruit expansion and maturation, helping grapes cope with heat stress.

3. Autumn:

   • After harvest (leaf fall), apply fertilizer to stimulate root regeneration and nutrient recycling for the next season.

III. Controlling Fertilization Amounts

1. Soil Type Adjustments:

   • Sandy soils: Require more nitrogen due to poor water retention.
   • Clay soils: Need less nitrogen but benefit from phosphorus and potassium.

2. Grape Variety Considerations:

   • Varieties like Jufeng (巨峰) need higher nitrogen, while Red Globe (红提) requires more phosphorus and potassium. Adjust amounts accordingly.

3. Avoid Over-Fertilization:

   • Excessive use leads to soil salinization and nutrient imbalance. Follow the principle: "Less is more, but balanced."

IV. Fertilization Methods

1. Deep Application:

   • Sprinkle fertilizer evenly on soil surface and incorporate into deeper layers. Suitable for most fertilizers, especially organic ones. Reduces nutrient loss via volatilization.

2. Trench Application:

   • Dig shallow trenches between rows or plants and place fertilizer directly inside. Ideal for chemical fertilizers. Increases root-fertilizer contact for better absorption.

3. Ring Application:

   • Create small holes around plants, fill with fertilizer, and cover with soil. Ensures even distribution, suitable for organic/chemical blends.

V. Post-Fertilization Management

1. Timely Irrigation:

   • Water immediately after fertilization to dissolve nutrients and aid root absorption. Avoid hot water to prevent root damage.

2. Soil Aeration:

   • Loosen soil lightly to improve aeration and water penetration. Be cautious not to damage roots.

3. Monitor Plant Response:

   • Observe for signs of over/under-fertilization (e.g., yellowing leaves, wilting). Adjust strategies if issues arise.

VI. Pest and Disease Control

1. Prevention First:

   • Use resistant grape varieties, proper spacing, and timely pruning to minimize pest/disease risks.

2. Scientific Pesticide Use:

   • Choose appropriate agents based on pest type, follow dosage guidelines, and avoid excessive spraying to protect the environment and human health.

By following these steps, nitrogen-based compound fertilizer can effectively nourish grapevines, ensuring robust growth and high yields. Fertilization is an ongoing process; adjust strategies based on grape growth stages and soil conditions for optimal results.
