How is top soil replenished ? In simple language please so I can easily understand the answer.?
Question:After a heavy rain, how is top soil replenished ? What is the composition of typical top soils ? Is it mainly organic or mineral ?
Answers:
During thunderstorms lightning causes nitrogen in the air to become attached or "fixed" to rainwater. This returns a small amount of the nitrogen back to the soil. Along with the decay of dead plants and animals this supplies essential elements for plants to regrow. It is a continuous cycle. Soil is largely mineral - various combinations of sand, silt or clay. The "ideal" soil for many plants is called loam, about 40% sand, 40% silt and 20% clay. Sand has the largest particle size and clay the smallest. Organic materials usually make up 1 to 7 percent of natural soils.
Organic is always better, usually manure and peat moss will do.
organic..use animal droppings to fertilize the topsoil
Hello
Compost, Manure, Peat Humus, Organic fertilizers, even earthworms. The best way is to till what ever you use into the soil the beneficial bacteria's will break down the compost's and such into rich soil. Espoma Organic Lawn Food is an easier way to do it because you just cast it on your lawn as you would any fertilizer and it act's as an immediate fertilizer and also replenishes the 15 basic nutrients that all plants feed from, Nitrogen, Phosphorous, Potassium, Boron, Magnesium, Iron, Zince, Calcium, etc etc. Goodluck

O Horizon - The top, organic layer of soil, made up mostly of leaf litter and humus (decomposed organic matter).
A Horizon - The layer called topsoil; it is found below the O horizon and above the E horizon. Seeds germinate and plant roots grow in this dark-colored layer. It is made up of humus (decomposed organic matter) mixed with mineral particles.
Types of Soil: There are many different types of soils, and each one has unique characteristics, like color, texture, structure, and mineral content. The depth of the soil also varies. The kind of soil in an area helps determines what type of plants can grow. There are 12 orders (types) of soil: Alfisols, Aridisols, Entisols, Histosols, Inceptisols, Mollisols, Oxisols, Spodosols, Ultisols, Gelisols, Andisols, and Vertisols.

The kind of soil in an area helps determines what type of plants can grow. Different regions of the world have different soils and different plant life. The development of soil is influenced by temperature, rainfall, the plant life which decays and adds richness to the soil, and the organisms which live in the soil.
rain affects mineral leaching Example: potassium
