[QUOTE="Sincock, post: 8120872, member: 156353"] A common observation... After applying granular Nitrogen you will typically see a 'flush' of growth. Grass in particular responds quickly to any granular applied. The 'flush' of growth you see after Ammonium Nitrate, for example, is the plant taking in loads of water to try and dilute the poison you have just applied. Nitrate is a poison, well Nitrite but you need Nitrate to get Nitrite and Natures solution to pollution is dilution. Ammonium Nitrate is also a salty fertiliser which will result in an uptake of water. I would use the example of us eating bacon... what do you do after eating salty bacon? Drink water, the plants do the same. Probably the easiest way to explain it. To the naked eye this greening after AN suggests a positive response to the N applied and a better crop. The reality is the crop is full of water and more susceptible to lodging and disease. The latter isn't an issue with grass (it is to cereals) but the reduced DM certainly is. Applying foliar N, which isn't poisonous or salty, will not result in an uptake of water and therefore provide no greening effect. To the naked eye it will look like there has been no response and the N hasn't worked. Less green, less fresh weight but I can promise you, you will see a difference when you analysis the grass as silage. Higher DM, increase ME, increased starch, increased sugars, higher protein (usually). It will have worked but the grass hasn't responded as you would expect. I have attached an on farm trial we did last year in Northern Ireland that compares CAN, Efficient 28 and Urea. In each trial foliar N provided better quality grass and you will see the same. Disclaimer... Folex mu35 is not Efficie-N-t 28, it is manufactured very differently and contains twice as much free urea so not directly comparable. The trial data has been done with Efficie-N-t 28 so again not comparable to what you have used but will give you an indication of what to expect. [/QUOTE]
