1、Effects of long

Soil fertility can deteriorate with the long-term use of NPK fertilizers, resulting in soil acidification, poor soil aggregate stability, and low levels of essential micronutrients.

2、EFFECTS OF FOLIAR FERTILIZATION AND FUNGICIDE

With these thoughts in mind, experiments were established to address the effects of foliar applied fertilizers and fungicide applications on yield and grade of peanuts.

3、Can Foliar Application of Nutrients Increase the Productive Potential

In peanut crops, foliar fertilization can be used during periods of greatest nutritional need, such as during early reproductive growth and production of leaves, flowers, roots and gynophores, penetration of gynophores in the soil and development of pods.

4、What Happens When Too Much Fertilizer Is Used? The Hidden Dangers

When fertilizers are overapplied, they can alter the soil’s pH levels, leading to a decline in soil fertility and structure. This can result in reduced crop yields, increased soil erosion, and decreased water retention capacity.

5、Consequences of Too Much Fertilizer

Overuse of chemical fertilizers can lead to soil acidification, reducing its fertility and capability to support plant growth. In addition, excessive nitrogen input can cause imbalances in plant growth, resulting in excessive foliage and poor development of flowers, fruit, and grain.

Foliar Fertilization as a Strategy to Increase the Proportion of Mature

Foliar application of nutrients is used by growers to remediate crop nutrient deficiencies, but anecdotal reports indicate there may be associated effects of accelerated crop maturity, particularly for irrigated peanut (Arachis hypo-gaea L.).

Effects of Foliar Fertilization: a Review of Current Status and Future

Foliar fertilizer application after soil fertilization is an effective method to increase the contents of trace elements in crops and crop yield, and to improve the soil environment. However, the application of inorganic foliar fertilizer results in difficulties in nutrient absorption and migration in plants.

Impact of Various Organic Fertilizers on the Growth, Yield, and Soil

fertilizer s significantly reduced the content of vanillic acid and coumarin in the soil, with the lowest coumarin content observed in the T3 and T4 s. In terms of peanut leaf diseases, the disease index of peanut leaf spot and brown spot were significantly lower in the orga.

The Overuse of Fertilizers in Agriculture: What Are the Alternatives

While these fertilizers have undeniably boosted crop yields, their overuse poses significant environmental and health challenges. In this article, we explore the consequences of fertilizer overuse and examine sustainable alternatives for modern farming.

Peanut foliar fertilizer is a nutrient solution applied to peanut leaves to enhance crop yield and quality. While easy to use, excessive application can negatively impact peanut growth and soil health. Below is an analysis of the potential consequences of overusing peanut foliar fertilizer:

I. Impaired Peanut Growth

1. Root Damage: Excessive nutrients (e.g., nitrogen, phosphorus, potassium) in foliar fertilizer can disrupt root development. Rapid root growth and elongated root hairs may reduce absorption efficiency, leading to oxygen deprivation and root rot.
2. Stunted Plant Growth: Damaged roots weaken the plant’s ability to absorb water and nutrients, slowing growth and preventing full maturation, which reduces yield and quality.
3. Reduced Photosynthesis: Overfertilization disrupts metabolic processes, lowers chlorophyll content, and decreases photosynthetic products, potentially accelerating premature aging.
4. Disrupted Flowering and Fruiting: Excess nutrients alter hormonal balance, inhibiting normal flowering and fruiting during the critical reproductive stage.
5. Declined Fruit Quality: Stunted growth and weaker photosynthesis result in smaller, misshapen, or discolored fruits, diminishing market value.

II. Soil Degradation

1. Soil Salinization: High concentrations of nitrogen, phosphorus, and potassium in foliar fertilizer can accumulate in the soil, leading to salinization, reduced fertility, and poor crop growth over time.
2. Soil Structure Damage: Excess nutrients alter microbial communities, accelerating organic matter decomposition, causing compaction, and reducing soil aeration and water retention.
3. Soil Acidification: Imbalanced nutrient ratios (e.g., excess nitrogen and phosphorus) acidify the soil, weakening its buffering capacity and harming crops.
4. Microbial Imbalance: Overfertilization disrupts beneficial soil microbes, allowing harmful organisms to dominate and further deteriorating soil health.
5. Heavy Metal Contamination: If the fertilizer contains heavy metals (e.g., cadmium, mercury), excessive use can pollute the soil, posing risks to crops and human health.

III. Increased Economic Costs

1. Higher Fertilizer Expenses: Overuse of costly foliar fertilizer increases input costs, burdening farmers and potentially driving them toward less efficient farming practices.
2. Labor Intensity: Excessive application requires more labor for spraying and management, risking waste and environmental contamination due to mishandling.
3. Resource Waste: Overapplication enriches soil beyond optimal levels and raises risks of water eutrophication, squandering resources.
4. Environmental Pollution: Excess nutrients contaminate soil and water, harm ecosystems, and compromise food safety, eroding market competitiveness.
5. Lower Market Competitiveness: Degraded fruit quality reduces prices and profits, discouraging farmers from sustainable production.

While peanut foliar fertilizer boosts nutrition, excessive use harms crop growth, soil health, and economic viability. Optimal application combined with integrated agricultural practices is key to sustainable peanut farming.
