The relative content of particles of miscellaneous sizes like sand, silt and clay in the soil are indicated by soil texture and is the most important property of soil. An analysis of soil texture is essential process because it determines the characteristics of soil that affects growth of plant and it has agricultural applications such as to determine crop suitability, to predict the response of the soil to environmental and management conditions such as drought or calcium requirements, as well as soil texture has good effect on management and productivity of soil. An achievement of objectives and goal of Analytical Spectral Device Fieldspec4 Spectroradiometer (350-2500 nm) is preferred which require less effort and is very efficient, rapid, more accurate, non-wasting and non-destructive technique. To non-destructively characterize the key soil properties the reflectance spectroscopy provides an alternate method. The research aims to predict soil texture with the use of ASD Fieldspec4 Spectroradiometer. The device is used for obtaining spectral signature measurement of different soil samples. The Partial Least Square Regression (PLSR) technique is a statistical method in which the predicted variables and the observable variables are projecting to a new space to find a linear regression model which can be a best method to determine soil texture distribution. This paper describes the observations of various researches to determine soil texture. The further research gives the best results for soil texture determination which is beneficial for growth of plant because the good soil texture is important to allow water into the soil which is vital for healthy plant growth.
