Greenhouse Growing

In Nebraska, a greenhouse offers several benefits, particularly during colder months. It provides a controlled environment that protects soybean plants from frost and unpredictable weather patterns. Greenhouses also help extend the growing season, allowing for earlier planting and potentially higher yields.

Consider investing in a 10×12 FT Greenhouse priced at $1,199 to ensure your soybeans thrive in a controlled environment.

Soybean Planting Dates in Nebraska

In Nebraska, soybean planting typically occurs from late April through mid-June. This timeframe ensures that the seedlings establish well before the hotter summer months, optimizing growth and yield.

Transplanting Soybean Seedlings

Unlike some other crops, soybeans are usually direct-seeded rather than transplanted. Seed should be sown in well-prepared soil when soil temperatures reach at least 55°F to 60°F. Aim for a planting depth of 1 to 1.5 inches for optimal germination.

General Care and Maintenance

Watering

  • Watering is crucial during the germination phase, particularly if rainfall is insufficient. Aim to keep the soil consistently moist.
  • After establishment, soybeans are relatively drought-tolerant, but supplemental irrigation may be necessary during critical growth periods, especially pod development.

Fertilizing

  • Conduct a soil test to determine nutrient needs for your fields. Apply fertilizer as needed at planting time to support healthy growth.
  • Incorporating nitrogen-fixing inoculants at planting can enhance soybean growth since soybeans have a symbiotic relationship with specific bacteria.

Pest and Disease Management

  • Regularly inspect plants for common pests such as aphids, soybean loops, and podworms. Monitoring and early intervention can prevent potential outbreaks.
  • Utilize crop rotation and resistant varieties as strategies to manage soil-borne diseases effectively.

Harvesting

  • Harvest soybeans when leaves turn yellow and most pods are brown. This usually occurs from late September through October, depending on the growing season conditions.
  • Ensure to harvest when moisture levels in the beans are around 13-15% for optimal storage quality.

The importance of good soil

Before starting to grow it is important to take a step back and find the condition of the soil in your garden,The optimal soil is a blend that includes the mineral-rich dirt along with organicrich organic matter that plants need to thrive.


In my garden I try to compost as mutch as possible, so I can mix in the nutrient ritch compost in my soil. I use both hot composting of food scraps and cold composting of all organic garden “waste”..
If you dont have the time or space for composting, it is possible to get compost ready to use in garden centers and Community Composting.
You can read more on Community Composting here: https://www.epa.gov/sustainable-management-food/community-composting

If you are uncertain of the quality of your soil, you can get easy to use soil tests at amazon for 17 dollars. Check latest prices here: Soil testing kit.

Also remember to check out how much sunlight your growing area gets, and that the rain drains well. If you treat your soil well and plan you crops according to your climate you will succeed with any plant you want.

The satisfaction when you harvest your own produce is well worth the time you put in 🙂
