[QUOTE="Simon Chiles, post: 5865230, member: 1233"] I think you need to consider the benefits to the rotation with both these crops rather than what each one produces individually. Both require attention to detail in establishing and initial growth period but once they are properly established then from then on they’re easy. Soya desiccation timing is critical to yield. Lupins have the advantage of not only fixing nitrogen but also exude citrates from their roots to release P for the following crop. I tell people that they’ll get a tonne per hectare more from the following wheat but a tonne per acre is often nearer the mark. Blue Lupins harvest earliest, for me they are normally end of August and Whites are normally second or third week in September. As [USER=601]@Devon James[/USER] says it’s best if you know someone who wants to buy them as feed or you need to be on a seed contract because otherwise the market is very limited. Soya is probably slightly harder to grow, although not difficult, keeping the pigeons off at emergence is the hardest part. Drilling depth is critical, Soya has a fixed length hypercotyl so if you wack them in too deep it’s game over. Soya needs about 240 kg/ha N which it can fix via the rhizobium but remember that the rule of thumb for legumes is that the N legacy is roughly 1/3 of the crop requirement ie 80 kg/ha which is significantly more than peas or beans. Soya has a wide range of herbicides approved for it. The biggest advantage of Soya is that the market already exists as huge quantities are imported. Soya harvest is normally third or fourth week in September. Soya UK have very good varieties that are tried and tested in the UK, I’m slightly cautious about other suppliers that are starting to get on the Soya bandwagon. [/QUOTE]
