Many farmers use sulphur-calcium fertilizer as a phosphate fertilizer, which poses a serious hidden danger to crop production!
After preliminary investigation, the use of sulphur-calcium fertilizer as a phosphate fertilizer for fraudulent sales seriously misled farmers. The main source of sulphur-calcium fertilizer is the waste slag produced by the production of sulphuric acid from phosphate ore. The main component is calcium sulphate. It is suitable for improving soil properties and providing soil sulfur and calcium. It cannot be used as phosphate fertilizer.
It is understood that most of the cultivated soil is a calcareous soil with rich calcium and sulfur content and does not need to be replenished. In order to meet the growth of wheat, in addition to nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, etc. are needed. If phosphate fertilizer is lacking, it will cause severe wheat yield reduction.
Therefore, you should not use sulphur-calcium fertilizer as a phosphate fertilizer, so as not to cause losses to yourself! Because superphosphate contains about 14% active ingredient (more than 80% of which is soluble in water), it is a water-soluble quick-acting phosphate fertilizer, agricultural lime. Limestone powder belongs to calcium fertilizer.
