3
Evaluate whether a soil is suitable for growing various plants by interpreting data found on a soil’s texture, drainage and pH level. Learning Target
4
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 The game plan…
5
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 Types
6
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…
7
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…
8
Base (alkaline) – pH above neutral Neutral – pH = 6.0-7.0 Acidic – pH below neutral Soil Management Practices…
9
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 Soil Management Practices…
10
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. Formative Assessment
