Overview
About this product
YaraVita Thiotrac 300 — a highly concentrated liquid with 100% soluble available sulphur: 1 l contains 300 g sulphur (22.8%, SO3 57%) and 200 g nitrogen (15.2%), which helps keep the N:S ratio in the plant. Per the maker, the sulphur is taken up faster than from a flowable powder or from products in which it must first oxidize.
The formulation includes a sticker, stabilizer, wetting agent and absorbent, and the product is widely used in tank mixes. On cereals the rate is 5 l/ha from the start of stem elongation to the first node. 10 l pack, United Kingdom.

Questions & answers
What farmers ask most
- Rates depend on crop, prior history and soil analysis. Urea and other straight nitrogen grades are not an NPK complex: a cereal ballpark is often 100–250 kg/ha of product, but the exact dose is an agronomist's call.
