[QUOTE="Warnesworth, post: 6481824, member: 3357"] I think [USER=618]@marco[/USER]'s sentiments about Albrecht/Kinsey are not far off mine. I wouldn't consider myself a disciple but Albrecht does have a lot of relevance, especially where we are trying to seek marginal gains in soil management in CA systems. As [USER=618]@marco[/USER] says above calcium is the constructive element, while magnesium, potash and sodium are all working against you to a greater or lesser degree. Add in their relative effects on soil pH, the laws of the minimum and maximum, why some elements will block others, and you start to understand why some soils become incredibly difficult to manage and don't perform as they should. Then to keep the cost down we treat the symptom rather than the problem, which as [USER=6]@Clive[/USER] points out treating the problem maybe prohibitively expensive. That said, I am not into soil balancing [I]per se [/I]but I do believe that we underestimate the incredible importance of calcium. I don't sell calcium before any clever dick suggest's I do. But I do see an awful lot of crushed rock sold as calcium that simply isn't fit for purpose (we test it ourselves to ensure this is fact) and so am not surprised when people say they added calcium and it didn't work. Also using soil pH to determine calcium applications is the most imprecise piece of science, (along with variable rate application's based on RB209 but that's another story). We also forget that salt based fertilisers are [U]incredibly[/U] effective at stripping out active calcium from our soils. I recently had the pleasure of spending a day with Neil Kinsey and can say that I think that many of the soils in the States that he deals with are probably more 'broken' than ours. Dr Tim Reinbott at the University of Misssouri is currently field testing Albrecht recommendations over multiple years. His work has found some surprising results... [/QUOTE]
