Description
The appearance color of calcium ammonium nitrate is generally off-white or taupe particles, and there are also green ones. Among them, ammonium nitrogen and nitrate nitrogen each account for half, and the nitrogen content is much less than the original ammonium nitrate. However, it has low hygroscopicity, is not easy to agglomerate, has good dispersibility, and has good physical properties.
A new type of high-efficiency compound fertilizer is a high-efficiency and environmentally friendly green fertilizer widely used in greenhouses and large-scale farmland. Calcium ammonium nitrate contains a large amount of calcium carbonate, and it has good effect and effect when used as top dressing on acidic soil. When applied in paddy fields, its fertilizer effect is slightly lower than that of ammonium sulfate with equal nitrogen content, while in dry land, its fertilizer effect is similar to that of ammonium sulfate. The cost of nitrogen in calcium ammonium nitrate is higher than that in ordinary ammonium nitrate. As a low-concentration fertilizer, calcium ammonium nitrate is a physiologically neutral fertilizer, and long-term application has a good effect on soil properties. It can be used as top dressing on cereal crops. Nitrogen in calcium ammonium nitrate particles can be released relatively quickly, while lime dissolves very slowly. The results of field trials in acidic soils showed that calcium ammonium nitrate had good agronomic effects and could increase the overall level of yield.
