Which soil is best for my plants? Greenhouse
Learning Target • Evaluate whether a soil is suitable for growing various plants by interpreting data found on a soil’s texture, drainage and pH level.
The game plan… • Short lecture reviewing the components of soil particles and how their characteristics effect soil drainage, aeration and texture • Discuss pH levels • Soil Analysis Lab: • Assess the soil’s drainage capabilities • Calculate soil particle percentages to determine texture • Conduct a pH reading
Soil Types • Best garden soil is loam= equal amount of sand, silt, and clay • Good drainage so oxygen is available for roots • Organic matter to hold moisture and provide plants with nutrients • pH range should be from 6.3-7.0 for most veggies
Soil Management Practices… • Clay Soils • Work up in the fall of the year - This allows drier soil in spring for earlier planting • Prepare “raised beds” to plant early in season • Work manure, residue, and leaves into soil to increase organic matter
Soil Management Practices… • Sandy Soils • Best when planted with a fall cover crop, rye or vetch and the worked in early spring - This adds organic matter - Helps to hold on to moisture and plant food • Soil tests should be done each year to determine nitrogen, phosphorus, and potassium levels as well as pH level.
Soil Management Practices… • Base (alkaline) – pH above neutral • Neutral – pH = 6.0-7.0 • Acidic – pH below neutral
Soil Management Practices… • pH is too high (alkaline) • Add sulfur to recommended amounts • pH is too low (basic) • Add lime to recommended amounts • When close to proper pH 5lbs/100sq. Ft. every 2-3 years should keep soil at good levels • Beans, peas, onions require high pH levels
Formative Assessment • Use the data you have gathered from your soil sample to answer the following questions: • Is this unknown soil suitable for growing tomatoes and daylilies based on the data you gathered about the soil’s texture, drainage rate and pH level? EXPLAIN! • Explain the importance that determining the best soil for your plants, in terms of money, production, and efficiency during the growing season.
