NEW! Grass Seed. Organic Sorgum Sudan. (Sorghum bicolor) Annual, fast-growing, heat-loving cover crop unsurpassed for adding organic matter to soils in hot, fairly dry situations. Loosens compacted soil, outcompetes weeds, and known to suppress nematode populations. A superb choice for reviving worn-out soil, particularly if followed by a legume. May be used as a quick-growing pasture or hay crop, but care must be exercised in feeding it to livestock due to concerns around prussic acid. Best to plant into warm soil. Seed at 1 lb./1000 sq. ft or 20 lbs./acre. 16,000 seeds/lb. Pkt plants 12 sq. ft.
