The Mexican Army seized a 120-hectare marijuana plantation, the largest ever found so far, in the northeastern Mexican state of Baja California, dpa rported.
An Army spokesman told the German Press Agency dpa Thursday that the plantation was in the municipality of Ensenada.
It was covered by a black screen, and it could not be detected from the air. Soldiers came upon it late Tuesday in a recognition mission near the village of El Marmol, about 2 kilometres from the nearest road.
According to the Army, around 60 day labourers are believed to have worked at the plantation, which featured its own generators and two wells for irrigation.
On Wednesday, 16 people from the state of Sinaloa were detained at a military checkpoint as they travelled to Ensenada in a bus. Six of them admitted they worked at the marijuana plantation.
The Army said the finding prevented the harvest of some 120 tonnes of the drug, with an estimated market value of 160 million dollars.
The marijuana plants seized, up to 2.5 metres tall, are to be burnt.
