[QUOTE="shields kaiser, post: 7266720, member: 15370"] The 140 part in your equation or the "multiplier" reflects the Dry Matter so 140 = 14%. In wetter weather I'd imagine you'd have grass dry matter at nearer 12 or 10%., so your multiplier would change to 120 or 100 in this scenario. As a side job, it would be a good idea to test some yourself so that you know what Dry matter is at certain points of the year. Cut 100g of grass and heat overnight in the oven until the sample doesnt get any lighter - the end weight is the dry matter of your grass at that point - e.g. 10grams was 10% DM. The "adder" (500 figure) wont be far away at 500 or 600 and I dont think it needs to alter much, but 'i'd find out further as cant remember what it is as a number, minimum volume of DM that you cant measure possibly. However in answer to your question, using your same formula (14%) and if grass is growing, I'd exepct to see the overall DM increase week on week, its strange that it is decreasing as you say, but possibly because the very wetter grass has less strength to hold up the plate and therefore even with more bulk there actually is less of it as Dry Matter. I've also been told in the past that you shouldnt measure in frosty weather as it gives a false reading too. Possibly someone else on here will be able to explain better though? [/QUOTE]
