MAKING THE PERFECT SEEDBED
After years of extensive field research, Case IH found that a stand can be in jeopardy if soil clods are too big or if the holes they roll out of are left in the field. Clod and valley sizes should be 6 inches or less in prairie soils and 4.5 inches or less in forest soils when coming out the back of a tillage pass in the fall.
SOIL QUALITY FOR STAND AND PLANT PERFORMANCE
Maximizing yield potential starts at the time of primary tillage, one of the most critical elements is soil output. Case IH has discovered that growers can dramatically reduce the risk of emergence problems in the spring by reducing both clod and valley sizes out the back of a tillage pass in the fall. Large clods leave holes, which are detrimental to seeds. The different heights in the soil surface result in variable moisture and temperature levels, with the holes staying wet and cold — one of the reasons for slow, uneven germination of seeds. The Ecolo-Tiger handles today’s realities of high plant population, tough Bt corn residue and earlier planting dates, providing aggressive residue sizing and mixing for more rapid nutrient cycling.
