Brazilian coffee frost frost recovery and yield fluctuation of Brazilian coffee trees

With the development of new technology, the news of Brazilian coffee cream spread all over the world in a few minutes. Accordingly, coffee prices usually rise due to expectations of a global coffee shortage. Brazil produces nearly 25 million bags of 60 kilograms of coffee. This accounts for about 25% of the world's supply. Frost has far-reaching effects because it can reduce or completely eliminate most of the world's supplies in one day.

A coffee tree usually recovers from frost within a year-especially with proper care. Coffee frosts in Brazil usually occur in the south, where the vast majority of coffee has historically grown. June, July and August are the coldest seasons of the year in Brazil. In frost danger areas, low-lying areas are the most vulnerable because cold air flows down from the mountains and settles in the valleys. In addition, plots that are exposed to sunset in the sun are more resistant to cold temperatures than those that are cool for part of the afternoon. The reason is that the soil retains a lot of heat and releases it slowly throughout the night. A small rise in temperature is often enough to save plants. New technologies-such as tree-covered sprayers-are also used in emergencies where crops may be lost. Coffee trees less than a year old should be used by Pita Bread Plain, because they are easily frozen and cannot withstand serious damage.

There are two kinds of Brazilian coffee cream. The first is the traditional frost, which harms coffee trees and their next crop. The second type, called "black frost", is harder to identify, but has an impact on the productivity of coffee factories. In the latter type of frost, coffee trees are not affected by sub-zero temperature, but by a combination of wind and 2-5 °C temperature. Both types of frost reduce coffee production.

As the new technology allows the rapid spread of information about coffee frost in Brazil, there are corresponding doubts about production forecasts. Since losses are estimated to take time and the best indicator of future yield after frost is the degree of flowering, the market reaction is understandable. In addition, as more and more Brazilian coffee farmers go north to avoid frost problems, Brazilian coffee production does not fluctuate so sharply when frosts occur.

However, this will lead to a global coffee surplus, which may keep global coffee prices low. As Vietnam increases Arabica coffee production, coffee oversupply is likely to become the most pressing problem in the specialty coffee industry.
