Deep application of organic fertilizer in vineyards to improve grape yield and quality

Overview

This solution presents a deep application method for organic fertilizers in vineyards using cow, sheep, and pig manure to significantly improve grape yield and quality. The approach enhances key fruit characteristics including aroma, sugar content, soluble solids, and the solid-acid ratio, all of which directly contribute to higher commercial value. Beyond fruit quality, the method improves soil health by generating active substances that positively reshape the soil microbial community, raise soil pH, and increase organic matter content. The technique is particularly relevant for grape production, which shows one of the strongest correlations between organic fertilizer use and improvements in fruit quality and market value among agricultural products.

Technical specifications

• Fertilizer types: Cow manure, sheep manure, and pig manure applied at depth
• Application equipment: Offset-type organic fertilizer deep application machine that creates ditches 40 cm deep and 30 cm wide, positioned 50 cm from the grapevines
• Soil improvements: Increased soil pH, higher organic matter content, and improved microbial community structure
• Crop benefits: Balanced root micro-ecology supporting normal crop growth, with single grapevine yields reaching up to 119 bunches in validated trials
• Target crop: Seven-year-old Red Globe grape variety

Technology readiness level

The method has been validated through soil improvement measures implemented in vineyards in Shanzhou District, Sanmenxia City, Henan Province, where grape growth reached the best level since planting. A five-year comparative study is underway using a 10-mu vineyard divided into a control group (no organic fertilizer) and an experimental group (with organic fertilizer), with measurements of grape quality and soil characteristics being collected to further quantify the benefits.
