How Deep Should Corn Be Planted? Master the Correct Sowing Depth
When planting corn for the first time, you will encounter all kinds of problems, such as planting too deep or the seeds failing to sprout, so how deep should corn be planted?
1. How deep should corn be planted?
When soil moisture is good, a corn sowing depth of 3-5 cm is suitable. But the specific depth must be determined according to soil conditions; for example, a sowing depth of 3-4 cm is suitable for sticky, wet soil, 4-5 cm for sandy soil, 5-6 cm for flat land and shaded land, and 6-7 cm for sloping land and sunny land. No matter which type it is, the deepest should not exceed 10 cm.
2. When is corn sown?
Henan: corn is planted in June, after the wheat harvest, and the corn harvest is around the Mid-Autumn Festival, that is, the end of September.
Shandong: because spring corn is sown early and has a long growth period, its yield is high. In the Shandong region, spring corn is generally planted in early April and harvested at the end of August.
Northeast: the sowing time is after Grain Rain (around April 20) and before May 10, and the harvest is generally after October 1 and before October 20.
