According to the department of soil survey of Pakistan, 400 soil categories are found in Punjab. 80% of these comprise 45 series. In broader sense soils are divided into three flexible groups viz. light, medium and heavy soils. In this video, we have elaborated about light soil and its salient features. Such soils are distributed more or less throughout Punjab but more frequently found in Thal area (Layya, Bhalker, Mianwali) and Cholistan Bahawalpur
Light soil or sandy loam is that type in which sand is found more predominantly than silt and clay particles. It may contain 50-85 % sand, 25-50% silt and 10-20% of clay. This category may be sub divided into sandy, sandy loam, silt loam and silt clay loam in accordance with the change in proportion of soil separets.
This type of soil if often less fertile, record yield cannot be obtained with common cultural practices, these are well drained and aerated, require repeated application of water and fertilizer and can withstand relatively unfit water. Crops like barley, root crops like carrot, radish, stem crops like sweat potato, leaf deposited crops like onion and garlic can easily be cultivated in such crops but potential yield cannot be achieved. With the passage of time, their category may be changed with improving canal irrigation status.
There are different types of soil in Pakistan. Soil survey has revealed that, there are more than 200 various types of soils with minor differences from each other. In this video, information about sandy loam soil has been given including its characteristics, quality of this type of soil, merits and demerits etc. Sandy loam soil can not be considered as a fertile soil. It has a low quantity of nutrients which are needed for plant growth. In simple words, we can say that, it gives result upto the extent as we use fertilizers like dap ,diammonium phosphate, diammonium phosphate fertilizer, diammonium phosphate, diammonium phosphate fertilizer, organic fertilizer, npk fertilizer, dap fertilizer, urea fertilizer, nitrogen fertilizer, potash fertilizer. Different types of soil amendments are needed to grow plants in this type of soil. It absorbs water better than other types of soils. This is the plus point for sandy loam soil. Soil stabilization elements are required to maintain its fertility. Humic acid, humic acid fertilizer, fulvic acid for plants is not required in this type of soil because it already has enough pore spaces in it due to the presence of sand.
