While adding a soil conditioner to crops or a garden can seem like a great way to get healthier plants, over-application of some amendments can cause ecological problems. For example, salts, nitrogen, metals and other nutrients that are present in many soil amendments are not productive when added in excess, and can actually be detrimental to ...
The type of soil—sandy, clay, peat, silt, loamy, or chalky or a mixture–will influence if the nutrients stay in the soil or go past the root line. Leaching can occur, which is when nutrients ...
Ultisol, commonly known as red clay soil, is one of twelve soil orders in the United States Department of Agriculture soil taxonomy. The word "Ultisol" is derived from "ultimate", because Ultisols were seen as the ultimate product of continuous weathering of minerals in a humid, temperate climate without new soil formation via glaciation .
Traditionally, garden soil is improved by amendment, the process of adding beneficial materials to the native subsoil and particularly the topsoil. The added materials, which may consist of compost, peat, sand, mineral dust, or manure, among others, are mixed with the soil to the preferred depth. The amount and type of amendment may depend on ...
Soil quality reflects how well a soil performs the functions of maintaining biodiversity and productivity, partitioning water and solute flow, filtering and buffering, nutrient cycling, and providing support for plants and other structures. Soil management has a major impact on soil quality. Soil quality relates to soil functions. Unlike water ...
The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt):
Soil aeration maintains oxygen levels in the plants' root zone, needed for microbial and root respiration, and important to plant growth. Additionally, oxygen levels regulate soil temperatures and play a role in some chemical processes that support the oxidation of elements like Mn 2+ and Fe 2+ that can be toxic.
After the garden has been laid out soil preparation is the next key aspect to consider for successful planting. Weeds and debris are removed from the beds and 3-4 inches of compost or manure is dug into the soil and left for a month in order to have nutrients spread around the soil; the process can be sped up by placing black or clear plastic ...
