  1. 8. The ability of a soil and crop system to hold water in the root zone.
  2. 13. excess water filling the spaces in the soil. Water drains from the soil most quickly.
  3. 14. a substance that provides nourishment essential for growth and the maintenance of life
  4. 15. The embryo of a plant’ also kernels of corn, wheat, etc., which botanically are seedlike fruits, including the ovary wall.
  5. 17. To develop into a plant from a seed, spore, or bulb.
  6. 19. Any matter, defined as organic incorporated in or on the surface of the soil. It may include undecomposed plant matter and highly humidified—sometimes used interchangeably with humus.
  7. 21. a group of textural classes in which the particles are finer than gravel but coarser than silt
  8. 23. is a mixture of minerals and organic material that covers much of Earth’s surface.
  9. 24. A mineral, or minerals, classified with the micas, expands into scales and becomes a loose, absorbent mass with treatment at high temperatures.
  10. 27. Process by which green plants, using chlorophyll and sunlight energy, produce carbohydrates from water and carbon dioxide and release oxygen.
  11. 28. Granular material of a size between sand and clay.
Down
  1. 1. The relative proportions of sand, silt, and clay particles in a mass of soil.
  2. 2. Soil or soil-like material in which plants are grown, also referred to as medium.
  3. 3. this nutrient helps the plant's immune system and rooting abilities
  4. 4. A volcanic glass having numerous concentric cracks that give rise to the perlitic structure and are used in synthetic potting media mix.
  5. 5. are part of the embryo and develop into the first leaves of the plant. Flowering plants are called angiosperms
  6. 6. This helps a plant put on lush, green growth and helps break down organic matter in compost
  7. 7. any material of natural or synthetic origin that is applied to soils or plant tissues to supply one or more nutrients essential to plant growth
  8. 9. water available for a plant to absorb
  9. 10. Two cotyledons or two leaves. Have leaf veins that are in a netlike pattern and have taproots
  10. 11. water that is unavailable to plants
  11. 12. Moving a seedling or grown plant from one place to another
  12. 14. A reading of the three main macronutrients, nitrogen, phosphorous, and potassium. A fertilizer label will read the percentage of each nutrient in the bag in percentages—for example, 20-10-5.
  13. 16. The early growth stage of a plant grown from seed as it emerges above the ground surface.
  14. 18. a domestically produced alternative fuel most commonly made from corn. It is also made from cellulosic feedstocks, such as crop residues and wood
  15. 20. material (such as decaying leaves, bark, or compost) spread around or over a plant to enrich or insulate the soil.
  16. 22. Fibrous, partly decayed fragments of vascular plants that retain enough structure to identify the peat as originating from certain plants (e.g., sphagnum peat or sedge peat).
  17. 25. One cotyledon or single leaf. Parallel leaf veins and fibrous roots such as corn
  18. 26. helps the plant’s overall reproductive system, its flower and fruiting capability and its tissue strength
