I have followed 10 years British springs. Spring rape is important crop. But mostly weathers are so cold that bees cannot forage rape. Rape needs 20C day temps that feed get a real yield from flowers.
I have followed my bees working on rape. If day temp is 18C, it is only 2-3 hours that amount , and then weather cools down again.
There are such phenomenon like "working hours of bees".
I found it with balance hive. It may be 3 hours, 8 hours or 12 hours. in a day
If night is cool, it takes time that nectar is dry enough after misty night. Then air must warm up. It takes time hours.
Then we have nectar on field. How many hour bees need time that they clean cectar from flowers. I have seen that they may clean nectar before 15 a'clock. Half of day's working hiurs give zero result.
If vegetation has 5 bees / square metre, no bees get yield from that pasture. Flowers do not secrete load in every 10 second.
