Boron is an essential plant nutrient because it assists with water regulation and cell formation in plants. Boron is lacking in soils formed from rocks low in boron, e.g. granite. Of course, if soils are overly sandy then leaching of nutrients, including boron, is frequent. Sometimes, the soil will possess a load of boron, but it's not in the correct form for root uptake. Likewise, the nutrient can become unavailable to plants when soil is of an alkaline pH. Deficiences frequently occur following liming or, if the spring has been significantly wet and is followed by a hot summer. Boron deficiencies are closely linked to calcium, and sometimes one can impact the other.
