“Towards digital soil morphometry”, the author described how proximal soil sensing and other tools can be used in soil profile descriptions where techniques and tools are not changed in recent decades. Digital landform metrics is defined as the application of tools and techniques to measure and quantify soil profile attributes and derive continuous depth functions. The application of these tools is compared to standard soil profile descriptions for 11 common attributes: horizons, texture, color, structure, moisture, mottle, texture, carbonates, rock fragments, pores and roots. These attributes are widely used in soil classification and are indicative of many soil functions. Commonly, a soil profile is divided into genetic horizons and the attributes are described, sampled and its properties analyzed in the laboratory. The information is used to classify soils and to interpret soil functions. Interpolative functions have been developed that use analytical data from soil horizons to estimate soil property values ​​at any depth or depth class. Say no to plagiarism.

In the agricultural sector parameters such as quantity and quality of products are important measures from the "point of view" of farmers. Soil is recognized as one of the most valuable natural resources, the pH property of which is used to describe the degree of acidity or basicity that affects nutrient availability and ultimately plant growth. A pH of 7.0 is neutral, and soils above or below this value are alkaline or acidic. Soil pH is an important factor in determining which plants will grow because it controls what nutrients are available for plants to use. A soil test is a process by which elements such as P, K, Ca, MG, Na, S, Mn, Cu, Zn are chemically extracted from the soil and measured for "plant available" content within the sample of land. Soil pH can be determined by soil color using digital image processing techniques. In which digital photographs of soil samples were used for soil pH analysis. Soil colors are the parts of the visual perceptual property where digital values ​​of red, green, and blue (RGB) provide a clue for capturing the spectral signature of different pHs in soil. “Determination of Soil pH using Digital Image Processing Technique”, The based technique is used digital image processing technique in remote sensing where digital photographs of soil samples have been used for determination of soil pH. The digital photographs were collected during sunlight. RGB values ​​in deep brown terrain. The correlation between the digital value and soil pH values ​​should be useful in determining the soil pH of different soil types. In "Soil Analysis - Determination of Soil pH - 2014", this document explores the meaning of soil pH and pH table for various agricultural crops. This article discusses the importance of soil pH. The procedure for calculating pH using the pH meter is explained. The principle of the potentiometric method is based on the measurement of.
