SEEDBED PREPARATION
EVEN EMERGENCE
SAME CONDITIONS FOR EACH PLANT
Zone A
The top layer must have a stable aggregate size and structure to reduce erosion and capping. Rapid heating of the soil and adequate oxygen supply to the germinating seeds is maintained. A load-bearing seed horizon into which the seeds can be embedded at an absolutely even depth over the whole area of the field. An unbroken association between the seed horizon and the capillary water conducting lower layer to ensure germination in the absence of rainfall. A formed barrier keeps the moisture and avoids water evaporation a certain time.
Zone B
Zone C
water evaporation barrier
access to capillary water
Disadvantages caused by incorrectly preparing the seedbed: 1. If it is inadequately compacted and/or at an uneven depth
If the soil is cultivated too loose or too deep, the seed has no connection to capillary water conducting ground beneath, meaning it depends primarily on essentially on rainfall for growth. This leads to uneven and delayed germination. 2. If the soil structure has been harmed by cultivating incorrectly at the wrong time and wrong speed, the soil can seal, reducing the oxygen supply and resulting in uneven germination. 3. If the land is cultivated when it is too wet, the result may be a compacted and coarse seedbed. Root growth may be restricted with reduced access to water and nutrients, causing poor plant growth and a tendency to fork.
