Soil Fertility Forage Management Sorghum is best suited to fertile soils. Ensure potassium levels are adequate in acidic soils. Do not exceed 110kg/ha of nitrogen. An independent soil test is advised before sowing. Avoid grazing or cutting sorghum below 15cm plant height. First grazing or cutting should be conducted at approximately 1 metre to increase plant productivity. Be aware of the risk of prussic acid (HCN) poisoning with forage sorghum's. Risk is greatest when crops are < 60 cm high or are moisture stressed or frosted. Cut or graze when 60-120 cm high to maintain best quality. 25552 S BUTTE AVE • FIVE POINTS, CA 93624 • UNITED STATES • PHONE: +1 (559) 884 2535 Sow seeds shallow into adequately moistened soil.
