Geostatistical Tools to Interpolate the Textural Variation Influences the Yield of Tapioca (Manihot esculenta)

Soil texture is an important feature that represents a variety of soil parameters such as bulk density, particle density, infiltration rate, hydraulic conductivity, water holding capacity, nutrient storage and availability, as well as soil aggregate movement, binding, and stability. Tuber development is influenced by the texture of the soil. The major goal of this study was to create kriged maps (Ordinary kriging map and semivariogram) to interpolate the soil texture for Tapioca growing soils in Namakkal District’s Paramthy block in unsampled areas. Nearly 254 surface samples were obtained for this investigation, which covered 19,149 ha of agricultural land with Tapioca as the predominant crop. Our findings indicate the utility of geostatistical techniques in analysing the spatial distribution of soil texture, specifically sand, silt, and clay content, which governs soil physical, chemical, and hydrological properties. Every crop has its own economic component, which may be below ground or above ground. Both require improved soil for high production, but crops with economic components below the earth rely heavily on soil texture. The findings, such as the supplied maps and their related variation, can be utilised to build and implement additional land management and soil water conservation programmes in the research area.
