Manganese deficiency (was Beans over?)
"Steve Harris" wrote in message ... In article , (Jaques d'Altrades) wrote: Store in a cool place in dry sand or peat over the winter, all in a plastic sack or bucket. Don't let them freeze. Interesting but my runners are not very healthy. I *think* it's manganese deficiency. The older leaves get mottled between the veins. At some stages it's quite pretty. at first, I thought it was Magnesium deficiency and used the MgSO4 spray I fixed the tomatoes with but no joy. Apparently, it's a problem with alkaline soil and beans. They can't get Mn out of such a soil and a foliar spray of Mn is the only way. Anyone know of a source of Mn for a spray? Or should I acidify the plot? I would have thought that an impossibility. There is no acidic counterpart to lime as far as I know. Franz |

Manganese deficiency (was Beans over?)
The message
from "Franz Heymann" contains these words: Apparently, it's a problem with alkaline soil and beans. They can't get Mn out of such a soil and a foliar spray of Mn is the only way. Anyone know of a source of Mn for a spray? Or should I acidify the plot? I would have thought that an impossibility. There is no acidic counterpart to lime as far as I know. When I was a anklebiter my father grew magnificent beans. He prepared two trenches and filled them with good things: compost, hoof and horn, bonemeal, dried blood etc, and grew beans on the same sites for many years. The ground there was quite alkaline, but I wouldn't think the trench fillings were! Since runner beans have few diseases or pests which attack them seriously, you can grow them in the same spot until you need to enrich the soil again. I can't remember which one, but at least one fertiliser usable as a foliar feed contains manganese. I used it on raspberries which were similarly suffering. I believe Baby Bio does - there may be a grown-up version. -- Rusty Hinge horrid·squeak&zetnet·co·uk http://www.users.zetnet.co.uk/hi-fi/tqt.htm |

Yes, I suppose you can make a very localised and temporary pH change like that, but it would not take long to be neutralised if there is a nearly infinite supply of limy minerals in the ground I can't remember which one, but at least one fertiliser usable as a foliar feed contains manganese. I used it on raspberries which were similarly suffering. I believe Baby Bio does - there may be a grown-up version. Miracle Gro contains manganese. It can be used as a foliar feed or watered into the soil. Franz |

Well there's ericacous compost, peat and sawadust which my blueberries thrive on. I believe that lots of manure will lower the pH as well. None of them will work for long if there is a limestone or chalk buffer in the soil, and treating anything other than a relatively small area will be prohibitively expensive. Increasing the pH of a soil is very much easier than decreasing it. Franz |
