This week farming editor Avalon Willing takes a look. When it comes to growing crops Elwyn Powell will give just about anything a go. Over the last 20 years he has combined agricultural contracting in the Waverley area with growing the likes of wasabi, radishes and squash for the Japanese seed market, as well as the usual grain crops. So the opportunity to grow cannabis legally was just too good to miss. Mr Powell is one of handful of people throughout the country who has granted a licence to grow hemp as part of a national trial. The organiser of the trial is an Englishman, Bruce Hill, who has had several years' experience in hemp production in the United Kingdom where the focus was on fibre and oil. These days he runs a company called Sustainable Seed Oils Ltd which imports hemp seed oil into New Zealand. Hemp, says Mr Hill, should not be confused with marijuana. "Although they are from the same family they are not the same. Cannabis sativa applies to both marijuana and hemp, a bit like roses =F1 some are red, some are creamy coloured, but all are recognised as roses. Of the hundreds of different varieties of cannabis only some are high in delta9-tetrahydrocannabinol (THC) the active compound that provides a high from cannabis." There are many varieties low in the compound and those with a THC content of less than 1% are often called hemp which is grown commercially all over the world for fibre and hemp seed oil. Mr Powell, Wanganui branch chairman of Federated Farmers, says he is always looking at diffferent crops. "I can see a future in this and I was more than happy to go through the protocols to get the licence. I went through week after week of filling in forms and Bruce Hill went in to bat for us as well." Prospective licensees were throughly vetted to ensure they were reputable citizens with no previous convictions for drugs or other crimes. Mr Powell planned to plant two 2ha blocks =F1 one to be used for sustainable seed production and the other to be harvested for silage which would then be tested as to its suitability as a stock food. However, the early experience of some other growers participating in the trial around the country showed that only 50-60% of seeds were germinating. So he reduced the area to 3ha =F1 a decision he has some regrets about because his crop is thriving. =46asamo hemp seed is the preferred option for seed oil production, but there was some difficulty and delays in getting hold of suitable supplies. It finally arrived in the country in early November after being impounded in the United States. It had come from Canada and was about three years old. The older the seed the less ability it has to germinate. While some other growers, like one in the Horowhenua, direct drilled the seed, Mr Powell had ploughed his paddocks about two months earlier and they had been fallow ever since. But wet weather delayed planting until November 30. "The husbandry side of it is an important lesson," says Mr Powell. "I'm chuffed with the cover we've got." The seed was drilled at a rate of 100kg/ha. The seed cost 10/kg. "All I've done is put it in the ground and left it. That's what you do with GE crops isn't it =F1 plant them and walk away because they don't require sprays. Compared to other crops hemp is a breeze. "A lot of people use hemp as a two-year crop when they are moving towards becoming organic. Really I shouldn't have put any fertiliser on but I felt I had to because I planted so late. Because it smothers the weeds there's no need for herbicides and there's no problem with pests." That is except for a few rabbits. "They've come out of the hedges but the staff have been shooting them. Perhaps they're attracted to the hemp because of the fibre and the acid. Or perhaps it's because it's palatable and has a bit of a kick. "But they reckon if you smoke the stuff the chances are far greater of getting lung cancer because it's so high in fibre." Mr Powell said one of the worst pests was possums, so he had been careful to select paddocks that were in a clear area. "They were my biggest fear. There's some native bush around but most of the area is fairly clear." Waverley, he says, has provided the ideal climate for growing the crop. "Ask the local dope growers. I've had a lot of advice on how to grow this stuff. For domestic marijuana it's apparently a very good area =F1 probably because of the unique bush and gully set ups." Mr Powell will harvest the bulk of the crop for seed oil but intends cutting and baling some hemp (when the plants are at three different heights) to trial as a stock food. "I'll do tests with it to determine the ME (metabolisable energy) and dry matter content. ME is the important one but I've no idea what the levels are. I thought the Poms could have told me that but they have focused solely on fibre and oil. But I've been told it makes pretty good dairy feed. I'll give the cows a high while the farmers are on holiday," he quips. "But seriously there is little likelihood of anyone getting a buzz from hemp because the crop must contain less than .3% THC =F1 a 30th the THC level found in cannabis used as a drug. "If it's over .3% we've got to kill it. Marijuana is 9% THC. And it's no good guys putting a rogue plant in here. The crop contains both male and female whereas with marijuana they want just the female plants." The result would be the two could cross fertilise and reduce the THC levels to nothing. Mr Powell says yields per hectare for seed production are an unknown quantity at this stage, but the grower in the Horowhenua had said he was hoping to harvest 1.5 tonnes/hectare and 300 litres of oil. "So I would expect to get at least four tonnes of seed =F1 a barley crop yields about 8 tonne/ha." Seed oil has a distinctive nutty flavour and is ideal for use in salads, dips and marinades. The seed, which is about the size and shape of a peppercorn, is more nutritious than even soyabean and contains more fatty acid than any other source. It is second only to soyabeans in complete protein (but more digestible by humans), is high in B vitamins and is 35% dietary fibre. The seed contains no THC. The oil is one of the least saturated and contains omega-6 and omega-3 fatty acids in the ratio 3:1 that the body needs." Mr Powell sees huge potential for the seed oil. "As a crop it's environmentally sustainable. No pesticides or herbicides are required and there are so many uses for it. But I think the biggest potential is not in the food industry but in the fibre industry. "In India they separate the fibre by hand. Germany is still working on a mechanism to separate the fibres efficiently and has invested $60 million in that." Hemp fibre is longer, stronger, more absorbent and more insulative than cott on. "It really is a wonderful plant. If we can get it established it's got so much potential. We've just got to find the right one for us and what its strengths are under our environmental conditions." - --- MAP posted-by: Josh
