Fertilizer is an important means of production to promote the growth and development of crops and improve the efficiency of agricultural production. In the face of a wide variety of fertilizers, combined with their own production needs, according to the type, characteristics, ingredients, and efficacy of fertilizers, can be said to be the necessary knowledge of many agricultural producers.
Farmers and families use fertilizer every day to help crops and gardens grow. Whether it’s a small garden for flowers or a large farm with thousands of acres of crops, fertilizers have been developed to help different crops grow in different soil and weather conditions.
Fertilizer is a substance added to the soil to improve plant growth and yield. Fertilizers were first used by ancient farmers, and with the discovery of the chemical needs for growing plants, fertilizer technology developed significantly. Modern synthetic fertilizers consist mainly of nitrogen, phosphorus, and potassium compounds, with the addition of secondary nutrients. The use of synthetic fertilizers has greatly improved the quality and quantity of food available today.
The fertilization method of potted plant fertilizer is different in each season. The spring and autumn season is the growing period of plants, and the demand for fertilizer is relatively large, so the amount of fertilizer needs to be increased. A small amount of fertilizer in summer, summer evening is the best time to fertilize, to avoid sunburn. When plants stop growing in winter, no fertilizer is needed.

Caustic soda is used in agriculture, industry, medicine, etc. The following is a brief introduction to the application of caustic soda in the textile industry：
1,Excellent color build-up
Caustic soda is used instead of soda ash for fixing, and even if the amount of 1/10 is substituted for soda ash, sufficient color yield can be guaranteed. Inadvertent addition of caustic soda during operation will have no effect on fiber coloration.
2. Wide adaptability in dyes and equipment, good dye reproducibility
Applicable to all kinds of reactive dyes, it has high color yield and reproducibility for reactive dyes of various structures; it is suitable for various equipments, especially in low bath ratio and aerosol dyeing machine, it shows its unique superiority. In the production of cheese yarn, the inner and outer layer difference can be effectively solved.
3,Shorten the dyeing time
Caustic soda is a new type of buffered solid base with less electrolyte and low ionic strength in the dissolution. Therefore, the coloring is slower during the caustic soda addition process, which makes the dye leveling better. Whether dyed dark or light, the caustic soda can be added in about 20 minutes, shortening the dyeing time.
4, Improve the quality of dyed products, reduce the repair rate.
