1、Boron Fertilizers

Boron fertilizer refers to substances that supply boron, a micronutrient essential for plant growth, which must be carefully managed due to the narrow range between sufficiency and toxicity levels for agricultural crops.

2、Boron Nutrition and Boron Application in Crops

Application of boron fertilizer is the mean to increase yield and quality of crops sensitive to B deficiency. Nowadays, borax is the most popular B fertilizer in China, which is usually used as foliar spray with a B concentration of 0.2%.

3、BORON

In general, the monocotyledons (grass species such as wheat, oats, sorghum, maize and sugarcane) have a lower requirement than the dicotyledons, i.e. soybeans, crucifers and pasture legumes. Boron deficiency occurs more commonly in dry weather.

Boron in fertilizer applications

To determine the optimum rate and method of applying sufficient boron for optimum yields, growers need to know the relative boron needs for their crops. When tested for spreadability, Granubor was consistent in every fertilizer spread tested.

Boron in Agriculture

Some crops show boron deficiency symptoms more commonly than others. Borax decahydrate and borax pentahydrate are most widely used borates as boron fertilizer. Sodium borates can be used as soil application and also as foliar application due to its high solubility.

AGRNMY Boron

Boron until 1926. Since then, there have been three main crops that consume most of the boron fertilizer manufactured today: alfalfa, apples, and Brassicaceae crops (e.g., cabbage, cauliflower, broccoli, and brus el sprouts). Because alfalfa’s need for boron is most widely known, alfalfa is recognized as the market’s largest consu

What Fertilizer Contains Boron? Essential Nutrient Sources

The frequency of boron-containing fertilizer application depends on factors such as soil type, crop type, and boron deficiency severity. As a general rule, boron fertilizers can be applied at planting, and then again at flowering or fruiting stages.

Advances in studies on crop boron nutrition and application of boron

In this article, we reviewed the achievements made by Chinese scientists focusing on the field research, including B nutrition diagnose and application of B fertilizers in crops, uptake and utilization of B, physiological function of B, genetic and molecular mechanism of B nutrition in crops.

Boron Dynamics and Sources for Soil Application

All factors that influence crop growth and yield must be assessed to improve sustainability, fertilizer use efficiency, and productivity, and that includes the use of micronutrients such as Boron.

Boron Fertility in Crop Production

• Application rates typically range from 0.5 to 1.0 lbs/acre of boron for crops such as corn, soybean, and cotton, but can be as high as 3 lbs/acre for highly responsive crops such as alfalfa or sunflower.

Boron fertilizers are essential plant nutrients that play a critical role in crop growth and development. They promote root system expansion, enhance stress resistance, and improve both yield and quality. In agricultural production, rational application of boron fertilizers is crucial for maximizing crop productivity and quality.

I. Applicability of Boron Fertilizers

Boron fertilizers are suitable for a wide range of crops, including:

• Cereals (e.g., rice, wheat, corn);
• Economic crops (e.g., cotton, rapeseed, tobacco);
• Vegetables (e.g., tomatoes, cucumbers, peppers);
• Fruit trees (e.g., apples, pears, peaches).

Boron enhances photosynthetic efficiency, facilitates nutrient transport and conversion, and ultimately improves crop quality and yield.

II. Types and Application Methods of Boron Fertilizers

1. Boric Acid

   • A common form of boron fertilizer with good solubility and stability.
   • Can be applied as a base fertilizer, topdressing, or foliar spray.
   • Caution: Excessive use may lead to soil acidification or boron toxicity.

2. Borax (Na₂B₄O₇·10H₂O)

   • A high-boron compound commonly used in fertilizers.
   • Dissolve fully before application to prevent clumping.
   • Can be mixed with other fertilizers to enhance efficacy.

3. Boron-Magnesium Fertilizer

   • A composite fertilizer containing boron and magnesium.
   • Suitable for standalone or combined use.
   • Tip: Control dosage to avoid overapplication.

4. Boron-Zinc Fertilizer

   • A composite fertilizer containing boron and zinc.
   • Compatible with other fertilizers but requires careful dosage control.

III. Application Methods

1. Base Fertilizer

   • Apply boron evenly to the soil surface during land preparation, then incorporate into the soil.
   • Suitable for large-scale application.

2. Topdressing

   • Apply dissolved boron fertilizer during the crop growth period.
   • Methods: Foliar spraying or direct soil application.

3. Foliar Spraying

   • Dissolve boron in water and spray directly onto leaves.
   • Rapidly increases boron uptake, but requires strict dosage control.

IV. Precautions for Boron Fertilizer Use

1. Avoid Overapplication

   • Excess boron causes soil acidification and boron toxicity, harming crop growth. Follow recommended dosages.

2. Prevent Incompatibility with Other Fertilizers

   • Phosphates, chlorides, etc., may reduce boron availability. Coordinate fertilizer applications carefully.

3. Consider Environmental Factors

   • Climate, soil type, and crop variety affect boron absorption. Tailor application strategies to local conditions.

4. Crop-Specific Needs

   • High-yield crops (e.g., rice, wheat) often require more boron.
   • Boron-sensitive crops (e.g., cotton, rapeseed) need stricter dosage control.

Boron fertilizers are vital for optimizing crop photosynthesis, nutrient transport, and overall productivity. To ensure effective results, select appropriate boron sources and application methods based on crop type, soil conditions, and environmental factors. Proper use of boron fertilizers guarantees healthy crop development and enhanced agricultural outcomes.
