Main Concepts Chapter 13: * Soil forming factors * Soil formation begins with fragmentation of parent material. * Parent material consists of ancient layers of rock, or more recent deposits from lava flows or glacial activity. * The first organisms to gain a foothold in modified parent material also contribute to soil formation. * Lichens form pioneer communities. * Decomposition of dead lichens further alters underlying rock. Humus is the organic material resulting from the decay of plant and animal remains. * It mixes with top layers of mineral particles, and supplies needed nutrients to plants. * It creates a crumbly soil that allows adequate water absorption and drainage. * Burrowing animals such as earthworms bring nutrients up from deeper soil layers, improving soil fertility. * * The organic material resulting from the decay of plant and animals remains is called………….? HUMUS * Soil properties: Soil texture Soil texture is determined by the size of mineral particles within the soil. * Too many large particles (sand, gravel) lead to......
