Boron deficiency in Southeast Asia
Boron is one of the essential nutrients in plants. As boron accounts for less than 0.01% of the total body mass of organisms, it is generally considered a trace element. Although the content is not much, it is indispensable to plants. Due to the alternating climate environment of the dry season and rainy season in Southeast Asia, the soil boron deficiency in Southeast Asia is quite serious.
Causes of boron deficiency in Southeast Asia
1. Growers have applied large amounts of nitrogen and potash, ignoring the importance of boron. For example, the tea is grown in Vietnam, in addition to the application of nitrogen fertilizer and potassium fertilizer such as the base fertilizer, also needs to supplement boron, otherwise, there will be tea leaf deformation, axillary bud growth, excessive development of the phellem layer and other boron deficiency phenomenon.
2. Heavy rains and soil leaching can make it more difficult for growers to maintain an optimal balance of nutrients in the soil, leading to boron deficiency in crops. For example, in rice and oil palm grew in Indonesia and Malaysia, boron deficiency prevents young leaves from growing and leaves remain short and narrow, with curly tips that are pale white or yellow. Oil palm is very sensitive to boron content, and leaf malformations such as "fishbone leaves" and "hook leaves", white stripes on leaves, and small seedless fruits are all related to boron deficiency.
3. The sandy soil of soil organic matter content is low, especially in the northeast, or rarely organic fertilizer of soil, are prone to boron deficiency phenomenon. Corn grown in Thailand, for example, removes large amounts of boron from the soil each year, and the most obvious signs of boron deficiency are irregular kernels and slow growth.
Methods for improving boron content in soil:
1. Apply boron fertilizer
Apply boron fertilizer directly to boron deficient crops through the Leaf blade. Edta-B, for example, is a 100% water-soluble fertilizer. boron is quickly absorbed by crops, especially at the bud and young fruit stages for best results.
2. Apply organic fertilizer
Organic fertilizer as soil base application, nutritional elements more complete. On the one hand, the boron contained in organic fertilizers can be released evenly for a long time to meet the requirements of the whole growing season of crops. On the other hand, organic fertilizer can improve the soil environment, enhance the ability of soil water and fertilizer retention, and promote the absorption of boron elements in crops.
3. Irrigate reasonably
Due to the climatic environment of southeast Asia, to control the crop water supply, prevent soil drought or waterlogging and reduce the degree to which the crop root system absorbs boron element.
