Technical Specifications
Corn Soil adaptation: Performs best on well-drained soils. Poorly drained sites will not allow timely planting and will reduce yields and increase competition from weeds. Moderately well-drained sites can be chosen if flooding is desired. Seedbed preparation: Well-prepared seedbed or no-till into a legume, small grain or old residue. Plant in 30 to 40 inch rows. Planting: March 15 April 25. Plant 16,000 to 18,000 seeds/acre, which is equivalent to 12-15 lbs/acre. Fertility requirements: Use soil test recommendations, or use 300 - 400 lbs/acre of 13-13-13. pH requirement: 6.0 to 6.5. Apply agricultural lime according to soil test recommendation. Grain Sorghum Soil adaptation: Grain sorghum is adapted to a wide range of soils. Soils best adapted are deep, well-drained, but yields can be obtained on heavy, clay-to-clay loams, shallow soils and soils not well-drained. Seedbed preparation: A clean, firm seedbed is necessary. Planting: April 15 May 15. Rates vary from 8 to 10 lbs/acre assuming the seed has an 80% germination rate and a 75% emergence rate. Cover seed about 1 inch deep. Plant in rows of 36 to 40 inch spacing for best results. Fertility requirement: Use soil test recommendations, or use nitrogen rates of 34 to 200 lbs/acre depending on desired yields. Potassium requirements range from 30 to 50 lbs/acre and potash from 60 to 100 lbs/acre. pH requirement: 5.5 to 6.5. Apply agricultural lime according to soil test recommendation.
Soybeans Soil adaptation: Widely adapted to drained, medium textured soils and heavier textured soils. Seedbed preparation: Prepare a clean, firm seedbed. Fertility requirements: A soil test is recommended or apply 200 lbs/acre
of 0-20-20. pH requirements: 6.0 7.0. If soil pH is below 6.0, lime with at least 1 ton of agricultural lime per acre. Soil Adaptation: A well-drained, productive soil is best; however, sunflower is adapted to a wide range of soils. Seedbed preparation: Prepare a seedbed as for cotton or corn. Planting: April 15 June 15. 10 to 15 lbs/acre in 36 to 42 inch rows using a corn planter with an 8 inch spacing within the row. Cover seed about 1 inch deep. Fertility requirements: Apply 300 lbs/acre of 13-13-13 at time of planting. pH requirement: Sunflower is adapted to a wide range of soil conditions.
Winter Wheat Soil adaptation: Winter wheat is adapted to most soil types throughout the state. Avoid wet, poorly drained, soils. Seedbed preparation: Prepare a clean, firm seedbed. Planting: September 1 November 1. Plant 80 lbs/acre (1.5 bushels) when seedbeds are conventionally prepared. Increase rates to 96 lbs/acre where wheat is "roughed in". Fertility requirements: Use soil test results for determination or 60 lbs/acre of nitrogen, 80 lbs/acre of potassium and 80 lbs/acre of potash. An additional amount should be added in February or March. Amount will depend on use. pH requirement: 6.0 to 6.5. Apply agricultural lime according to soil test recommendation.
