- what are the type of soil erosion?What are the main elements that determine soil capacity to produce higher yields? If a plant shows stunted growth as well as yellow leaves then what type of nutrients would be deficient? How to address the issue? Please please answer thatWhy do tropical and temperate soils have different rates of nutrient regeneration?
- Name the following as soil forming processes: a. Soil erosion b. Formation of humus c. Weathering of sand d. Nutrients absorbed by plant roots e. deposition of organic matter f. Leaching of water along with dissolved ionsWhat is the most important thing you can do to a mineral soil in order to ensure an adequate supply of and maximum availability of plant nutrients?How can soil erosion lead to desertification? It reduces the level of organic matter It promotes flooding that destroys vegetation It promotes salinization that destroys soil structure Which of the following is not a factor that may lead to urban sprawl? Pollution Immigration Overpopulation Which statement is NOT true about soil salinization? Soil dehydrates due to decrease in accumulation of water underground. Starts by attempting to wash the salts out of the topsoil by pumping more water. Results to the damage and killing of plants as saline water surrounds its deep roots. Which would most likely happen if too much nutrient entered a freshwater ecosystem? Algae will decrease, leaving few food resources, for fish. Nutrients would sink to the bottom, increasing soil deposition. Algae breakdown lowers dissolved oxygen, causing fish to suffocate.
- How are soils formed? Through the breakdown of what material? Why are new soils not suitable for most plant species?How large are the forces that allow leaves to pull water from the soil?Why are total soil concentrations poor indicators of the amounts of ions that may bioaccumulate (enter the food chain)?
