Spotting boron Deficiency

Visual Symptoms of Boron Deficiency

Boron deficiency in various crops shares certain characteristics including misshapen, thick, small, brittle leaves—typically affecting the youngest leaves first. 
 
Leaves
Misshapen, thick, small, brittle leaves—typically affecting the youngest leaves first
Stems
Short, shrunken stems and stunted or reduced growth points
Fruit
Cracked or watery tissue or fruit
Kernels
Malformed or irregular fruit or kernels 
Different regions have unique boron challenges—and opportunities.

Africa
Africa
Throughout Africa, soils can benefit from application of refined boron. Of course, this vast region comprises a multitude of climates, soil types, and crops. Yet frequent droughts and pervasive sandy soils mean that most growers here can see higher yields and greater ROI through the use of refined boron. Learn More
Australia / New Zealand
Australia / New Zealand
Australia and New Zealand are well known for their wide expanses and thriving agricultural industry. With numerous areas of volcanic or sandy soil and fairly high rainfall, refined boron can be beneficial when applied correctly. Learn More
China
China
China is the world’s largest agricultural economy, feeding one fifth of the global population on just over one-tenth of its arable land. China's food security is dependent on making the best use of its limited arable land and water resources. Like many regions of the world, China’s soil suffers from boron deficiency. Understanding the value of boron can help Chinese growers improve soil nutrition and continue to meet the country’s production needs long into the future. Learn More
Europe
Europe
European growers face boron-depleted soils, especially given the demands of widespread crops such as rapeseed. Most growers here are aware of the need for micronutrient supplementation. 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
The United States and Canada encompass vast swaths of rich farmland that feed much of the world. From the corn fields of Illinois, to the apple orchards of Ontario, to California’s fertile Central Valley, agriculture fuels regional economies. Boron is essential for healthy crop yields, yet it is the second-most deficient nutrient across North America. Correcting boron deficiency requires an understanding of multiple factors—including weather, geography, soil conditions, and crop requirements. Since these elements vary widely across the U.S. agricultural landscape, growers need to tailor their micronutrient approaches to conditions in their region. Learn More
Southeast Asia
Southeast Asia
This region fluctuates between drought and heavy rains and is characterized by sandy soils in many areas. These conditions increase boron deficiencies, which can harm valuable crops such as rice, tropical fruits, and oil palm. Many growers in Southeast Asia can benefit from improving soil health with boron supplementation. Learn More
