Choosing plants to grow in clay soil takes some discretion. When it is very wet, it … Clay particles are very small but, because this allows more particles to fit in any given space (say 1cm cubed), they have huge surface area that dominates the physical properties of soil. Clay soil can be a good thing many plants grow well in it. Properties of Clay Soil. In both cities and the countryside, selection of sites with the best soil is an important engineering decision in the building process. The density of clay is the cause of the two biggest drawbacks of clay loam. It has the highest water holding capacity. The term 'soil' refers to 'The upper layer of the earth's crust, in which plants grow. This soil is common to many parts of the world, limiting what homeowners, gardeners, and farmers can grow. The higher the percentage of clay in a soil the lower the infiltration rate will be. Wet clay soil feels sticky in your hand. Clay is rich in nutrients plants need to grow, holding calcium, potassium, and magnesium. While this soil type can be difficult to work with, it can also be improved to be a very good growing medium. Clay particles are amazingly dominant in a soil. As a noun clay is a mineral substance made up of small crystals of silica and alumina, that is ductile when moist; the material of pre-fired ceramics. This leaves little room for air and water movement for plants. The size of the soil pores is of great importance with regard to the rate of infiltration (movement of water into the soil) and to the rate of percolation (movement of water through the soil). 5- The strength of the clayey soil depends on the loading and boundary conditions and generally drained and undrained conditions are considered for short term and long term behavior of the clayey soils. Soil Profile – Soil Horizon: O horizon, A Horizon, E horizon, B Horizon, C Horizon or Parent rock, R Horizon or Bedrock. Pore-water pressure play a major role in strength and deformation of clayey … ... For growing crops such as wheat, gram, and paddy, the soil should be good at retaining water and rich in organic matter is suitable. If your area's growing season typically includes three to six months of temperatures that average higher than 70 F, and you have clay soil that stays wet most of the year, then rice varieties are options for you to grow.

Avoid drought-tolerant plants with either aromatic, silver or finely divided foliage, however. It consists of weathered rock, organic matter, air spaces and water. In the composition of the clayey soil we find for the most part extremely small diameter particles which have the particularity of being considerably cohesive with each other. Hold off on turning the soil until it either dries out to the point of cracking or softens up enough to get your shovel or tiller through easily. The soil content is well suited for several species of trees and shrubs that thrive on the nutrient-rich top layers of the clay, while moist, compacted portions of the soil have played a key role in ceramics and pottery for thousands of years. Therefore, clayey soils having these characteristics are useful for such kind of crops. 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. Prior to crop cultivation, certain factors have to be considered. Clay soil has many crevices that can hold onto salts and can make plants unable to grow successfully. The soil is usually formed when rocks break up into their constituent parts. Naturally, crops need a well drained soil to produce optimally; especially in their early stage. Clay soil definition is - a soil that contains a high percentage of fine particles and colloidal substance and becomes sticky when wet. Rice (Oryza sativa) is another crop that thrives in clay soil, growing best in constant moisture and heavy soil.Rice, however, needs a long, warm growing season. In loamy soils, the proportion of large and small particle is the same. In sandy soil, most of the soil particulars are bigger than 2mm in diameter. A soil with equal parts of these three mineral particles size classes is called a loam soil. If both criteria are not met, the soil is poorly graded gravel (GP). Learn more.
