Field crops refer to crops grown on large fields, such as wheat, rice, sorghum, corn, cotton, and pasture. The following is a compound fertilizer formula for field crops:

Corn: 30-5-5 / 28-6-6, 25-10-5, 25-10-16, 27-14-9 (high tower technology)
       28-6-8 (Rotating drum humic acid process) The crop is suitable for high nitrogen, low phosphorus and low potassium formula

Wheat: 25-13-7, 25-14-6, 25-17-9, 27-17-7, 27-14-9 (high tower technology)
       24-15-8, 18-12-10, 18-18-18, 23-20-7, 21-14-7 (drum humic acid process) This crop is suitable for high nitrogen and high phosphorus formula
       15-15-15, 16-16-16, 17-17-17, 18-18-18 (ammonia process)
        If balanced chlorine is used, supplement nitrogen

Rice: 25-10-16, 25-10-18, 24-6-10, 24-6-16 (high tower technology)
       18-12-10, 20-13-10, 18-18-18 (rotating drum humic acid process)
15-15-15, 16-16-16, 17-17-17, 18-18-18, 22-8-10 (ammonification process) Rice planting fertilizers generally use a formula with potassium content of about 10, nitrogen The content is controlled about 20, and the nitrogen in the formula is not enough to supplement nitrogen.

Rape: 30-5-5 / 28-6-6, 25-10-5, 25-10-16, (high tower craft)
        18-6-6, 15-6-9, 15-15-15 (drum technology)

Peanut: 14-16-15, 15-15-15 (spraying process)
      18-12-10, 20-13-10, 18-18-18 (rotating drum humic acid process)
