Thanks to its important role in plant growth, absolute need to boron was identified 82 years ago, yet its exact mechanism in herbal structure has not fully been understood.
Boron regulates glucose diffusion in the cells, growth and division of the cells, and photosynthesis metabolism. Plants can grow and foliate without boron, but losses might occur in fruit or seed production.
The research made on nutrition and physiology of vegetables reveals that boron greatly improves the growth and quality of vegetables. Thanks to boron doping to vegetables, improvement is observed in growth evolution, intra-cellular sugar and starch transfer, circulation of nutritious substances throughout the plant, formation of hormones inducing growth, root development, and formation of blossoms and buds.
Boron is an indispensable micro-nutrient for fruit trees in terms of blooming, fruitage and fruit quality. Increase in the capacity of blooming and fruitage, decrease in rotting and perishing of the peel and core of fruits, acceleration in the transmission of sugar and nutrients from the leaves to the fruit, decrease in the number of poorly growing branches, and an associated decrease in the number of fruits falling from the trees are observed on a fruit doped with adequate amount of boron.
Amount of boron needed by plants to complete their development is quite low. For this reason, the practice should be precise; boron should not be added to the plant without an analysis on soil. As between plant species, there are significant differences between sub-species in terms of boron content and tolerance to boron. For instance, 3 kg of boron is applied per hectare of sugar beet; however it is 1 kg for wheat.
Boron can be applied to the soil through different boron (boric acid, borax, etc.). It should be noted that boron source to be applied should be neutral so the pH value of the soil is preserved, and be easily soluble during the application.
