Forest soil in acidic forest ecosystems is ecologically and economically important. The most basic dynamics of forest ecosystems can be said to be forest soil. The acidity of the forest soil may change the chemical, biota and hydraulic properties of the soil, thereby altering soil formation properties and soil composition. Therefore, many studies and caution are required for acidification of forest soil. Forest soils are usually found to exhibit a pH value of 4 to 6 even in medium to low acidic deposition areas (Binkley et al., P. 12.
Forest soil is characterized by the deposition of organic matter from the forest. Humic rust dominates the forest soils and is primitive at higher levels, resulting in highly acidic conditions known as pooled soils. However, in lowlands and lowlands, it has low acidity and is called brown soil. There are forest soils in the Himalayas and the north, the Ghats mountains in the western and eastern part, and the other mountains of the peninsula. High levels of organic matter and nitrogen in the soil of the hillside of Assam and Meghalaya
Most of the topography at the foot of the Himalayas is covered with the soil of the forest. Forest soil is devoid of potassium, phosphate and lime. When applied properly, it is very suitable for agriculture. Plant plantations such as tea, coffee, spices, tropical fruits, corn, barley etc in this kind of soil. Various kinds of crops are planted in the desert soil that supplies water. Normally, this type of soil occurs throughout the Western Aravallian Mountains of Rajasthan. In the Tar Desert, the soil spreads to the Haryana State, the Northern Region of Punjab State and the Kachi Mountains of the South. In recent years the Canadian province of Rajasthan has introduced canal irrigation with the Indira Gandhi Canal and it is a major producer of cereals and cotton in the desert soil.
In forest areas, soil is mainly red soil. In regions with moderate precipitation, they are subdivided into relatively fertile, weakly acidic ozrosol (red, brown, yellowish brown, relatively drainy soil), more acidic and less fertile in the extreme southwest It changes into soil. Oxide, annual precipitation exceeds 65 inches (1,650 mm). Ozuzol occurs in a wide area of the coastal and northern Savanna area. Like woodland areas, they are the best agricultural land. Coastal savanna is rich in soil types such as tropical black soil, tropical calcareous soil, acid sewage, sodium salt. Most soils are not of agricultural importance except for the tropical black soil known locally as Akuse clay. The clay of Akuse fills the vast area of the coastal savanna plain; it is heavy and difficult to handle, but it reacts well to planting under irrigation and mechanical cultivation.
