In this session, experts from chemical and fertiliser specialists Yara will present two sessions with a focus on understanding how certain chemicals can
improve your crops.

Session 1 - Speaker: Fabrice Cabot, Yara France

The first called ‘Key to managing nitrogen and iron applications in sparkling wine viticulture’ will be presented by Fabrice Cabot from Yara France. He
is agronomic advisor for the French wine making regions with many years of experience under his belt.

Session 2 - Speaker: Giz Gaskin, Yara UK
1594222810641.png

The second, called ‘The importance of foliar applied calcium in viticulture’ will be with Yara UK fruit expert Giz Gaskin, who has eight years of experience in the fruit industry both in the UK and abroad.

Good morning everyone

I am Giz from Yara UK, my colleague Fabrice Cabot is with Yara France, welcome to the Yara seminar. I'll be here throughout the seminar, before returning to the Yara exhibitor stand. If you have any questions please type them below.

While 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 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 Giz

Are there any negative impacts on the soil from applying Iron Chelates? Are there any organic methods to apply iron?
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.

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.

Hi

yes I appreciate that your products are foliar but wouldn't a holistic approach to plants/soil and calcium be more beneficial ( so long as product is made available in the right way to both ) ?

Good morning Hugh

Yara products are both foliage and soil applied. A holistic approach for me is a lifestyle choice for the grower and may well yield them a good soil type and understanding of soil microbial condition with greater organic matter content. Calcium availability without formulation in my opinion would require a higher OM soil to make it available to the plant. This could be achieved through regular testing and assessment of the soil condition. Something Yara Labs could help with. In addition to using a secondary cropping or inter row cropping to boost soil fertility. Though with an extra cropping the system would need more feeding not less. In my opinion there is no better way to get calcium directly into the grape than to use a foliage feed.

Best regards

Giz
