Sandy soilSandy soil

Sandy Soil- This type has the biggest particles and the size of the particles does determine the degree of aeration and drainage that the soil allows. It is granular and consists of rock and mineral particles that are very small. Therefore the texture is gritty and sandy soil is formed by the disintegration and weathering of rocks such as limestone, granite, quartz and shale. Sandy soil is easier to cultivate if it is rich in organic material but then it allows drainage more than is needed, thus resulting in over-drainage and dehydration of the plants in summer

Sandy soil is easier to cultivate if it is rich in organic material but then it allows drainage more than is needed, thus resulting in over-drainage and dehydration of the plants in summer

. It warms very fast in the spring season. So if you want to grow your plant in sandy soil it is imperative that you water it regularly in the summers and

Loamy soilLoamy soil

Loamy SoilLoamy Soil- This soil consists of sand, silt - This soil consists of sand, silt and clay to some extent. It is considered to and clay to some extent. It is considered to be the perfect soil. The texture is gritty and be the perfect soil. The texture is gritty and retains water very easily, yet the drainage retains water very easily, yet the drainage is well. There are various kinds of loamy soil is well. There are various kinds of loamy soil ranging from fertile to very muddy and ranging from fertile to very muddy and thick sod. Yet out of all the different kinds of thick sod. Yet out of all the different kinds of soil loamy soil is the ideal for cultivation.soil loamy soil is the ideal for cultivation.

Chalky soil Chalky soil Chalky SoilChalky Soil-Unlike Peaty soil, Chalky soil is -Unlike Peaty soil, Chalky soil is

very alkaline in nature and consists of a large very alkaline in nature and consists of a large number of stones. The fertility of this kind of number of stones. The fertility of this kind of soil depends on the depth of the soil that is soil depends on the depth of the soil that is on the bed of chalk. This kind of soil is prone on the bed of chalk. This kind of soil is prone to dryness and in summers it is a poor choice to dryness and in summers it is a poor choice for plantation, as the plants would need much for plantation, as the plants would need much more watering and fertilizing than on any more watering and fertilizing than on any other type of soil. Chalky Soil, apart from other type of soil. Chalky Soil, apart from being dry also blocks the nutritional elements being dry also blocks the nutritional elements for the plants like Iron and Magnesium.for the plants like Iron and Magnesium.

many of them are no deeper than eight or many of them are no deeper than eight or nine inches below this is what gardeners nine inches below this is what gardeners call the subsoil ,which may be similar in call the subsoil ,which may be similar in character to the material above ,and yet character to the material above ,and yet which may not contain available plant which may not contain available plant foods it is important to try and get the soil foods it is important to try and get the soil to as great a depth as possible. to as great a depth as possible.
