Boron Deficiency in Southeast Asia

Boron deficiency map of Cambodia, Laos, Myanmar, Papua New Guinea, Philippines, and Vietnam

Extreme weather impacts production

This region’s weather patterns and boron-thirsty crops make it difficult to maintain adequate B levels. Many growers can benefit from an annual application of refined boron.

High demand crops need supplementation

Sandy soils, high rainfall, and low soil fertility can create less than optimal growing conditions. High yield growers replenish their soil with boron to ensure maximum production.

Intensive cultivation, boron deficient soil

Valuable export crops like rice and sugarcane remove large amounts of boron from the soil. Growers recognize the value of B to offset the effects of intensive cultivation and achieve maximum yields, season after season.

Boron Deficiency in the Region

Cambodia, Laos, Myanmar, Papua New Guinea, Philippines, Vietnam
Because of the region’s weather patterns and the popularity of boron-thirsty crops, soil often lacks the organic matter that helps to maintain adequate boron levels. As a result, many Southeast Asian growers can benefit from annual application of refined boron.

Indonesia and Malaysia
In Indonesia and Malaysia, heavy rain and soil leaching can complicate growers’ ability to maintain optimal nutrient balance in the soil. Soil type and compaction also increase the likelihood of boron deficiencies, which can negatively affect the rice and oil palm grown here, reducing growers’ yields and profits.
