1、Effect of Nitrogen Fertilization on Tree Growth and Nutrient

This effect of the increasing content of available forms of nitrogen indicates that the trees did not take up more fertilizer, probably caused by exceeding the fertilizing needs of trees.

2、The Effects of Nitrogen Fertilizer on Plant Growth

Nitrogen is an essential element for plant growth and development; however, due to environmental pollution, high nitrate concentrations accumulate in the edible parts of these leafy vegetables, particularly if excessive nitrogen fertilizer has been applied.

The objective of the presented paper was the determination of the effect of nitrogen fertilization on the content of mineral components in cherry tree leaves and in the soil of a cherry tree orchard.

Excessive nitrogen fertilizer can cause significant harm to cherry trees, primarily manifesting in the following aspects:

1. Nutrient Imbalance: Nitrogen is an essential nutrient for fruit tree growth, but overapplication leads to excessive soil nitrogen, making it the dominant nutrient absorbed by plants. This prioritizes nitrogen uptake, causing deficiencies in other critical elements like phosphorus and potassium. Such imbalances disrupt normal physiological functions, resulting in stunted growth and reduced fruit quality.

2. Root Damage: High nitrogen concentrations in soil accelerate water evaporation, drying the soil. Plants then require more water to maintain physiological activities, but excessive moisture can lead to root hypoxia, impairing root growth and function. Chronic damage reduces the roots’ ability to absorb water and nutrients, negatively impacting plant growth and yield.

3. Increased Pest and Disease Risks: Excess nitrogen creates an environment conducive to pests and diseases, such as root rot, leaf spot, and sooty mold. These directly harm cherry trees and lower fruit quality. Additionally, nitrogen promotes the proliferation of pathogens and pests, exacerbating infestations.

4. Reduced Fruit Quality: Overly high nitrogen levels in plants dilute sugar and vitamin content in fruits, leading to poor taste, nutritional loss, and issues like malformed or cracked cherries.

5. Environmental Pollution: Excess nitrogen increases the risk of soil leaching and groundwater contamination. Rainwash can carry nitrogen into water bodies, causing eutrophication and harming aquatic ecosystems. Nitrogen also seeps into groundwater, contributing to pollution.

6. Soil Acidification: Excess nitrogen induces soil acidification. In acidic conditions, nitrate (NO₃⁻) converts to nitrite (NO₂⁻), reducing effective nitrogen availability. This hinders plant nitrogen absorption, subsequently affecting growth and yield.

Mitigation Measures:

1. Rational Fertilization: Adjust nitrogen application based on cherry tree growth stages and soil conditions. Increase nitrogen during key growth periods (spring and autumn) and reduce it in summer and winter.

2. Control Nitrogen Doses: Avoid overapplication to prevent environmental pollution. Optimize timing and methods to limit usage.

3. Balance Fertilizers: Combine nitrogen with phosphorus, potassium, and other nutrients to maintain soil equilibrium.

4. Improve Soil Organic Matter: Enhance soil structure and water/nutrient retention by adding organic fertilizers or practicing crop residue incorporation.

5. Strengthen Pest Management: Regularly monitor trees, promptly identify issues, and implement targeted control to minimize pest/disease impacts.

excessive nitrogen severely harms cherry trees. Careful regulation of nitrogen fertilizer usage is crucial to ensure healthy tree growth.
