Products Description

Introduction

Fruit enlargement is a demanding growth stage in which developing fruits compete strongly for water, carbohydrates and mineral nutrients. A suitable late-stage fertilizer program should support this demand without relying on excessive vegetative nutrition.

LVT Fruit Enlargement Water Soluble Fertilizer is a high-concentration liquid PK formulation containing P₂O₅ at 500 g/L and K₂O at 600 g/L. Potassium supports osmotic regulation and the movement of photosynthetic products within the plant, while phosphorus participates in energy transfer and metabolic processes required during active fruit development.

Boron and copper provide additional micronutrient support for plant tissue formation and enzyme activity. The product is intended for use from established fruit set through the main enlargement period, with the exact application program adjusted according to crop type, climate, soil conditions and existing fertilizer inputs.

Key Benefits

1. Concentrated Potassium Supply

Provides 600 g/L K₂O for crops with increased potassium demand during fruit enlargement and early maturation.

2. Fruiting-Stage Phosphorus Nutrition

The concentrated phosphorus content supports plant energy transfer and metabolic activity during periods of intensive crop development.

3. Supports Assimilate Movement

Adequate potassium nutrition helps regulate water balance and the transport of carbohydrates from photosynthetically active leaves to developing plant organs.

4. Boron and Copper Supplementation

Boron supports normal tissue development, while copper functions as a micronutrient involved in several plant enzyme systems.

5. Suitable for Crop-Specific Programs

The concentrated liquid formula can be incorporated into professional fruiting-stage fertilizer programs after the appropriate crop rate and compatibility have been confirmed.

Compatibility and Precautions

Conduct a small jar test before combining the product with other fertilizers or crop-protection products.
Because the formulation contains a high phosphorus concentration, avoid mixing it directly in concentrated form with calcium- or magnesium-rich fertilizers.
Pre-dilute the product before adding it to a spray tank or fertilizer system.
Use clean water and maintain continuous agitation during preparation.
Avoid foliar application during high temperatures, strong sunlight or rainfall.
Store the sealed container in a cool, dry and well-ventilated location.
Follow a crop-specific rate to avoid excessive nutrient concentration.

FAQ

1. When should this fertilizer be applied?

It is intended mainly for the period after stable fruit set, when fruits enter active enlargement. The exact starting point depends on the crop and local production program.

2. Is it suitable only for fruit trees?

No. It may also be used for fruiting vegetables, grapes, strawberries and melons when a concentrated PK input is appropriate.

3. Can it be applied through foliar spraying?

Foliar application is suggested, but the dilution ratio should be confirmed according to crop sensitivity, temperature and spray-water quality.

4. Can it be mixed with calcium fertilizer?

Do not combine concentrated phosphate and calcium products in the same stock solution. Separate applications or tanks are generally safer. Always conduct a compatibility test first.

5. Is this a fruit-coloring fertilizer?

Its main positioning is fruit enlargement and late-stage PK nutrition. Any effect on coloration or soluble-solid development will depend on the crop, environment and overall nutrient program.

6. How should the application rate be determined?

The rate should be selected according to crop type, growth stage, irrigation method, climate and previous fertilizer inputs. Confirm the final program before commercial application.
