Full-time staff numbers are down by nearly 30% in the past 10 years.
Seasonal figures have also decreased in the past 10 years.
The 2017 Agricultural Statistics report says that crop rotation is needed to reverse the trend of the falling value of exported produce.
The Growth, Housing and Environment Department say by introducing new crops, like hemp, could reverse this trend.
