What is granular lime nitrogen and its use in agriculture.

Calcareous nitrogen (calcium cyanamide) is a kind of granular slow effect alkaline medicine and fertilizer product which is produced by original patent technology. It has double effects of medicine and fertilizer. The main component is 60% calcium cyanamide and the content of available nitrogen (n) is more than 20%. Effectively control soil borne diseases and insect pests such as root knot nematode, root swelling disease, Fusarium Wilt and lotus root rot, and kill blood control snails and longevity snails. It can provide nitrogen and calcium nutrition for crop growth, and the sustained release of fertilizer effect lasts for 4-5 months. Adjust the pH of soil, accelerate the maturity and transformation of organic fertilizer. Kill monocotyledonous grass and reduce grass damage. It can inhibit the nitrification of nitrogen in the soil, improve the utilization rate of nitrogen and protect the agricultural production environment. Calcium cyanamide is a kind of efficient soil disinfectant. Its disinfection principle is that the monocyandiamide and liquid dicyandiamide, which are produced by the decomposition of calcium cyanhydride in contact with water, have a broad-spectrum killing effect on the fungi, bacteria and other harmful organisms in the soil, can prevent a variety of soil borne diseases and underground pests, and also have a certain control effect on the root knot nematode which has been plagued the agricultural production in the facility. In particular, it has a good effect on fungal damage, such as Sclerotinia of lettuce, stem rot of pea, root swelling, retting, soft rot of cruciferous vegetables, and blight and bacterial wilt of spinach. The method of lime nitrogen disinfection is easy to use, low cost and free of any residual poison

Practical operation safety and other advantages.
