Good morning Hugh, as you say Calcium is very important to plant health, my thoughts of its effects on SAR in viticulture deserves a more detailed response which I would like to reply to by email if you would update me with your contact please ? Best regards GizWhile calcium is important in the physical process of plant health ,what are you views on the biological effects calcium has ,especially with the SAR responses and its effect on plant health
Good morning Johnathan, use of Yara iron Chelates hold little impact on the soil if applied by recommended dosage. Yara Chelates are formulated and tested at our labs in Poklington to ensure the best formulations both on both fertigated and prilled products.Are there any negative impacts on the soil from applying Iron Chelates? Are there any organic methods to apply iron?
Good morning Hugh, text chat is running very slow and doing some interesting things my end.many thanks ,Also with calcium ( being a metal) what are your thoughts on its ability over and its effects on SAR responses to improve soil biology and the symbiosis within the zonal layers ,as well as the effects on vertical water movement upwards that is over and above flocculation
Good morning Hugh, text chat is running very slow and doing some interesting things my end.
My discussion on Calcium is focused on feeding vine directly via the foliage, using a Yara formulation proven to deliver Calcium directly to the target area. Negating the need to consider Calcium at root zonal level. In this case the fruit and surrounding leaf.
Calcium within the rooting zone in viticulture is interesting not only from a stand point of its impact on the biology though most Calcium being immovable is locked in heavier soils. Microbialy broken down at the root zone, to more soluble forms for uptake Calcium is slow in moving from soil to plant root.
But also as the calcium in root stock is one aspect but we need consider the sap transfer of calcium between the root stock and graft. This I believe the key benefit of application of calcium in vine should focus on highly soluble formulations like YaraVita CALCINIT and foliage fed YaraVita STOPIT to mitigate the delay of uptake.
