No footnotes date April 2009 Image Bodenart.jpg thumb soil types In terms of soil texture , soiltype usually refers to the different sizes of mineral particles in a particular sample. Soil is made up in part of finely ground rock geology rock particles, grouped according to size as sand , silt and clay . Each size plays a significantly different role. For example, the largest particles, sand, determine aeration and drainage characteristics, while the tiniest, sub microscopic clay particles, are chemically active, binding with water and plant nutrient s. The ratio of these sizes determines soiltype clay, loam , clay loam, silt loam, and so on. In addition to the mineral composition of soil, humus organic material also plays a crucial role in soil characteristics and fertility for plant life. Soil may be mixed with larger aggregate, such as pebbles or gravel. Not all types of soil are permeable, such as pure clay. There are many recognized soil classification s, both international and national.

Unreferenced stub auto yes date December 2009 A soil conditioner , also called a soil amendment , is a material added to soil to improve plant growth and health. A conditioner or a combination of conditioners corrects the soil s deficiencies in structure and or nutrients. Purpose The type of conditioner added depends on the current soil composition, climate , and the type of plant. Some soils lack nutrients necessary for proper plant growth. Some hold too much or too little water, with water conservation aided in the latter. They can be incorporated into the soil or applied to the surface. Materials Agricultural lime Lime is used to make soil less acidic , as is lime containing crushed stone . Fertilizer s, such as manure , anaerobic digestate or compost add depleted plant nutrient s. Materials such as peat , diatomaceous earth , clay , vermiculite , hydrogel , and shredded bark will make soil hold more water. Gypsum releases nutrients and improves soil structure. Sometimes a soil inoculant is added for legume s. Unless clay is incorporated into a healthy crumb Soil structure structure , water may bond to it too strongly to be available to plant roots or run off before penetrating the surface.

Over time, this created a very rich agricultural soil which could be over 1m in depth unlike our modern arable soils, which tend to be just 30 cm deep.
