Soil & Compost Matter Science/Geology
What is soil? • Soil is composed mostly of mineral particles, air, water, and organic matter—plants need all of these to live. • The quantities can vary and determine the type of soil you have.
Types of Soil • Sandy – light and drains rapidly • Clay – heavy, sticky, and becomes waterlogged • Medium loam – moisture retentive yet well drained
Choosing plant according to your soil • Acid Soil – yellow-orange, pH value below 7 and soil is acidic • Neutral Soil – bright green, pH value of 7 and soil is neutral • Alkaline Soil – dark green, pH above 7 and soil is alkaline
Improving your soil • Clear the site—no roots, weeds, large rocks, etc. • Improve soil texture and structure—through both adding organic & inorganic matter.
Composting • ORGANIC MATTER –Well-rotted manure, leafmold (decomposed fallen leaves), composted shredded bark, plant fibers • Grass clippings, old flowers, coffee grounds, egg shells, craps for kitchen items (like cut-off peels, pieces of onion, apple cores, etc.) & other once living, but now dead things
