Available in PDF, EPUB and Kindle. Book excerpt: Conventional soybean production in the midsouthern United States has involved planting in a seedbed that had been shallow-tilled in the fall or spring just before planting. Moisture deficits that frequently occur during the growing season reduce yield of soybean in this traditional production system. Field experiments were conducted at Stoneville, Mississippi (lat 33°26'N), on Tunica clay (clayey over loamy, smectitic, nonacid, thermic, Vertic Haplaquept) and Sharkey clay (very-fine, smectitic, thermic chromic Epiaquert) from 1993 through 2000. The objective was to compare yields and economic returns from plantings of MG IV and V soybean varieties grown on the two soils after shallow (ST) and deep (DT) fall tillage. Net returns were calculated as the difference between income and all direct and indirect costs excluding those for land, management, and general farm overhead. Costs for tillage in DT were $12 ti $17 per acre greater than those for tillage in ST. Yields and net returns resulting from DT were greater than those from ST in all years on the Tunica soil. Yields and net returns from nonirrigated April/early May plantings after DT on Sharkey clay were significantly greater than those from ST in only 1 year out of 5. Yields and net returns from nonirrigated mid-May/early June plantings after DT were never significantly different from those of ST. The DT treatment followed by irrigation of the soybean crop the following year did not affect yield or net return. These results indicate that deep tillage of Tunica clay soil will result in significantly greater yield and net return. while deep tillage of Sharkey clay soil only has potential for increasing both when plantings are made in early April.

Available in PDF, EPUB and Kindle. Book excerpt: Extract: Average per-acre returns differ little for most U.S. corn and soybean farmers using various alternative tillage strategies, according to this analysis of 1980 farm-level production data. Midwest conventional-till soybean farmers, however, accrue a significantly higher average return than do Midwest no-till farmers. Most conservation-till soybean farmers in the three major producing regions incur significantly lower input costs than do conventional-till soybean farmers, but also harvest lower yields except in the Southeast. Significant differences were found in the use of specific corn and soybean inputs among alternative tillage strategies.

Available in PDF, EPUB and Kindle. Book excerpt: Conservation tillage systems and rotations with corn (Zea mays (L.) increases surface residue and make popular choices for erosion control in soybean (Glycine max (L.) production. Tillage and system (rotation) affect levels of residue input which in turn affect the response of the soil and plants. Few studies have looked at the long term (23 years) effects of management practices on soil and soybean physiology. The objectives of this study were to (i) determine the effects of surface residue on soil temperature throughout the growing season, (ii) determine the effect of amount of residue on SOC, and (iii) determine the physiological response of soybean to residue, system and tillage treatments. Rotation and NT increased surface residue and soil organic carbon (SOC) for the top 0-5 cm of soil in both years of data collection. Continuous soybean and tillage increased maximum soil temperatures but did not affect minimum temperatures over the course of the study. The differences in plant height and canopy coverage were limited and not directly related to changes in soil temperatures. Long term decisions in tillage and system have a direct effect on soil response but the physiological response of soybean isn’t fully understood.
