1、Effects of potassium fertilization on cesium

Therefore, persimmons were cultivated in pots with different amounts of potassium (K) fertilizer (+0 g, +20 g (standard level), and +40 g of K sulfate/pot), and the concentration of 133 Cs in leaves and fruits was investigated.

Revisiting potassium

Soil potassium (K) deficit is extremely challenging for global food security, necessitating optimal K-fertilization strategies to reconcile crop productivity and soil fertility.

Effects of Rootstock Type and Potassium Fertilization Rate on Growth

Thus, we purposed in this study to evaluate the effect of different potassium fertilization rates and rootstock type and their interactions on trees growth, flowering, yield, fruit quality and nutrient status of ‘Costata’ (Diospyros kaki) persimmon trees, grafted on D. kaki and D. lotus seedlings.

In agricultural production, rational fertilization is key to improving crop yield and quality. As an essential nutrient for plant growth, potassium plays a critical role in the development and growth of persimmon trees. excessive application of potassium fertilizer may have adverse effects on these trees. This article explores the consequences of over-fertilizing persimmon trees with potassium.

1. Impact on Growth and Development

Excessive potassium application can inhibit the growth and development of persimmon trees. Potassium promotes cell wall synthesis, increases cell size, and enhances cell density, which may disrupt normal growth patterns. Additionally, while potassium boosts photosynthesis and accumulates photoassimilates, excessive levels reduce the plant’s ability to absorb other nutrients, leading to nutritional imbalances.

2. Effects on Fruit Quality

Over-fertilization with potassium negatively impacts fruit quality. Potassium stimulates the synthesis of sugars, acids, and vitamin C in persimmon fruits. excessive potassium raises sugar content to undesirable levels, altering taste and flavor. It also affects mineral uptake (e.g., calcium and magnesium), which are vital for tree health and fruit quality. Consequently, fruit quality deteriorates.

3. Damage to Root Health

Excessive potassium harms root systems. While potassium typically supports root growth and nutrient/water absorption, overly high concentrations elevate soil osmotic pressure, impairing water uptake. Prolonged excess potassium also leads to soil salinization, further compromising root integrity.

4. Reduced Stress Resistance

Over-fertilization weakens the tree’s resilience to stress. Potassium normally enhances drought, cold, and disease resistance. excessive potassium accumulation reduces stress tolerance. During adverse conditions (e.g., drought or freezing temperatures), surplus potassium accelerates cellular damage, increasing mortality risks.

5. Ecological Disruption

Excessive potassium disrupts ecosystems. Unused potassium in soils is metabolized by microbes, releasing excessive K⁺ ions that cause salinization, degrade soil structure, and hinder microbial activity. runoff may contaminate groundwater, exacerbating environmental pollution. Long-term overuse threatens ecological balance.

Excessive potassium fertilization poses significant risks to persimmon trees. To ensure healthy growth, apply potassium judiciously, considering soil conditions, climate, and plant needs. Complementary soil management practices will help maintain fertility, ecological stability, and optimal growing conditions for persimmon trees.
