[QUOTE="Sincock, post: 8098964, member: 156353"] I doubt there is much info on many of the other foliar N products as they are all pretty new to the market. 3 / 4 years ago Efficie-N-t 28 was probably the only foliar available and in the last 12 months alone there have been at least 5 new products released. A great question re free urea volatilisation... we know that with only 6% free urea in efficient 28 you will be applying 1.5 kgs free urea / ha This is a tiny amount over 1ha. As urea provides N as an amide (NH2) it is very easily and very quickly absorbed through the plant leaf, therefore, it will be absorbed / used before it can volatilise into the atmosphere. With Folex mu35, you will be applying 2.9kgs free urea / ha which will is still low and again likely to be used before it volatilises. That's the beauty of urea, its attached to a carbon (technically making it organic) and the N is in amide form which is literally the building blacks of protein. Advice is always very similar but 20L / ha = 25kgs / ha = 7kgs N / ha and will replace, more or less, 40kgs N / ha from granular. Applying more than this in a single does will see diminishing returns. The Nitrogen has a half life which means after 4 weeks you will have used 95% of the 7kgs N applied. Foliar N is great but it needs to be used properly or you wont see the benefits / get the return on investment so whatever you are using it's worth doing your homework 👍 [/QUOTE]
