The price of coriander rapidly increased not too long ago. Many farmers quickly changed their crops to increase their production of coriander, which gradually began to enter the market in large volumes. The great market conditions, however, did not last long. The price of coriander suddenly began to fall in the last week of October. Farmers abandoned large fields of coriander that suddenly became worthless as the labor cost of harvesting the coriander exceeds the market price of coriander.
There are two main reasons for farmers to abandon coriander fields. The first reason is the sudden drop in coriander prices. Even if the farmers sell their coriander, they will still lose on the labor cost of harvesting it. The second reason is the weather, which recently became cold and rainy. The product quality of coriander decreased as a result, which makes it more difficult to sell.
