define humus and silt.
Answers
Answer:
Humus is the organic constituent of soil, formed by the decomposition of plant materials, and can be bought in bags at local gardening stores. ... Silt soils are nearly the same as sand soils, expect they have a consistency more like clay and darker in colors. Silts hold nutrients well but do not hold water very well
Answer:
Humus is dark, organic material that forms in soil when plant and animal matter decays. When plants drop leaves, twigs, and other material to the ground, it piles up. ... The thick brown or black substance that remains after most of the organic litter has decomposed is called humus.
Silt is granular material of a size between sand and clay and composed mostly of broken grains of quartz. Silt may occur as a soil or as sediment mixed in suspension with water. Silt usually has a floury feel when dry, and lacks plasticity when wet.
