After a lot of education, now many of our farmers have begun to pay attention to the use of calcium and magnesium fertilizer But when should calcium magnesium fertilizer be used? How to use it more scientifically This is a regular solanaceous melon and fruit crop One of the highest utilization periods for this calcium and magnesium is after the end of the slow seedling after the fixed value Ah, and then in the middle and early stages this combination is the most efficient Wait until after this late period ah mid late period after This calcium and magnesium fertilizer, this utilization rate is absorbed and this absorption rate is rapidly going down So if we supplement calcium for fertilizer at what time is ten steps in the early You know, after the crop was set, after the fire was poured, after the water was painted, when we first applied the fertilizer Began to pay attention to the supplement of dry magnesium fertilizer dry magnesium fertilizer supplement Of course, what about calcium and magnesium fertilizer if it's just absorbed through the root After all, he also has a quantity limit. After all, your quantity cannot be too high. After all, you still need to You can't have too much NPK for this The rest of the amount can be supplemented by the slope of a page Root absorption and leaf absorption such as a combination of calcium magnesium fertilizer a method of use Ah, the magnesium bar ah, this this quantity which is relatively better ah, magnesium sulfate Ah, generally only through the root absorption is no problem, especially calcium must be added on this page to do a supplementary supplement But you have a lot of friends who say that I don't have to tell you that I'm not going to be able to supplement this amount directly through the page So you have to have both the leaves and the roots supplement each other so that this amount of calcium is sufficient for the whole crop Ah, this is one. This is another one. The selection of calcium is also critical If you choo se calcium nitrate you have to be aware that this calcium nitrate has that nitrogen in it and that it could be used to boost the growth Ah, in addition, the calcium in sugar and this calcium and this is no nitrogen element ah, calcium is specifically for calcium But this this is probably going to cost a little bit more than this calcium nitrate but it's going to have a little bit more stability than calcium nitrate
