Ecofibre's Industrial Hemp Fibre Production Guide. 2. Hemp is a 4 m tall annual, daylight sensitive, fibrous plant. It is a summer crop, grown for Fibre, Grain & Oilseed in many countries. There are over 2,000 lines, with low THC.
That cost gap has narrowed, however. With better screens and technology that helps the plants power themselves by recycling the energy used to suck in water-in a way, like a hybrid car regenerates power from its own motion-the typical cost of running desalination plants can dip below $2,000 an acre-foot.
The cost of fertilizer plus application must be subtracted from this. At a fertilizer price of 82 cents per pound of actual nitrogen, the fertilizer cost for 100 pounds nitrogen per acre is $82 per acre. Add an application cost of $5 per acre, and the total cost of fertilization is $87 per acre.
