Boron in Plant Nutrition

Boron Deficiency Symptoms

Boron Deficiency Symptoms

Plants initially may not exhibit obvious symptoms of nutrient deficiencies other than a slower growth rate, which may be due to other factors. When moderate or severe nutrient deficiencies occur, most crops exhibit visible symptoms which are typical for deficiencies of a particular nutrient. Knowledge of boron-deficiency symptoms can help in diagnosing deficiencies. Symptoms should be confirmed with results of soil tests and plant analyses, and appropriate corrective action taken.

The Role of Boron in Flowering and Fruit, Nut and Seed Formation

The Role of Boron in Flowering and Fruit, Nut and Seed Formation

One of the important functions of B in plant nutrition is its role in fostering pollen growth and development, which is important in seed set and the resulting fruit, nut and grain production. Therefore, it is important to know the available B status for specific crops and the environmental conditions which may reduce B availability prior to, and during the critical period just before and during seed set. One or more foliar sprays of a B source such as Solubor®, depending on the specific crop, can help ensure that there is sufficient available B at this critical period.

Boron Mobility in Various Plant Species

Boron Mobility in Various Plant Species

Boron is a micronutrient required for all plant nutrition. While it has been generally accepted that boron is phloem-immobile in plants, recent research has shown that boron is mobile in the phloem tissue in a number of species. Diagnosis of boron deficiencies and the most efficient methods of boron application differ in plant species with respect to boron mobility or immobility. Knowledge of the relative mobility of boron within a particular plant species will improve the ability to diagnose boron deficiencies and supply the needed boron for optimum crop production.

Functions of Boron in Plant Nutrition

Functions of Boron in Plant Nutrition

Boron is a micronutrient required for all plant nutrition. The main functions of boron relate to cell wall strength and development, cell division, fruit and seed development, sugar transport, and hormone development. Some functions of boron interrelate with those of nitrogen, phosphorus, potassium and calcium in plants. Balanced nutrition is essential for optimum crop growth. Soil application of Granubor® 2 or foliar sprays of Solubor® or can be used to ensure an adequate B supply for optimum growth.
