European growers face boron-depleted soils, especially given the demands of widespread crops such as rapeseed. Refined boron can help, and offers a variety of application methods to meet growers’ needs. Learn More
India and Bangladesh
India and Bangladesh
Growers in this region have a high agricultural demand for boron, which is especially deficient throughout Bangladesh and eastern India. Monsoon patterns and depletion from the variety of high-yield crops in the area mean that refined boron supplementation is vital to help prevent fruit and flower drop and protect growers’ livelihoods. Both family growers and larger land holdings can benefit from the application of high-quality, highly available refined boron. Learn More
Latin America
Latin America
Latin America—comprising Mexico as well as countries throughout Central America, South America, and the Caribbean—is a vital contributor to the world’s food and agricultural resources. With a great deal of farmable land and a wide range of available crops, this region relies on boron for optimal yields. Learn More
North America
North America
Canada and the United States comprise vast swaths of renowned farmland. From the corn fields of Iowa to the apple orchards of Ontario, boron plays an important role in the health of North American agriculture. Learn More
Southeast Asia
Southeast Asia
Many growers in Southeast Asia can benefit from improved soil nutrition supported by boron supplementation. The region’s fluctuations between drought and heavy rains, as well as sandy soils in many areas, increase the leaching of boron and can harm valuable crops such as rice, tropical fruits, and oil palm.
