Abstract

Soil, as a growth medium and through its various functions, plays a vital role in the production system. Empirical models are functions to explore widely available dataset to generate the impedance of one property on other correlated soil properties. In this paper, we tried to develop some empirical equations and easily understandable graphical representations for gaining better knowledge, particularly for vertisols of central India. The soil samples were collected from research farm of JNKVV, Jabalpur, India during the period 2018-2019. The samples from surface and sub-surface soil were analysed for SOC, cation exchange capacity, bulk density, penetration resistance and soil textural analysis, compiled to develop a regression models. The relationship of SOC with cation exchange capacity and bulk density; clay content with cation exchange capacity, bulk density, penetration resistance and liquid limit were developed. The models were found statistically significant with good predictability. Soil clay content had direct linear correlation (p< 0.05%) with coefficient of determination (R2) = 0.64 for CEC, 0.607 for bulk density, 0.732 for penetration resistance and 0.738 for liquid limit of soil. Soil organic carbon also had direct linear correlation (p< 0.05%) with coefficient of determination (R2) 0.849 while, bulk density (R2 = 0.74) was found inversely correlated with of soil organic carbon.

Conclusion

For vertisols of central India the predicted models can be used for evaluating the existing soil management practices, soil fertility assessment and nutrient recycling. The models are statistically significant and suggestions are accepted. The function can be utilized to generate expensive and laborious soil properties. Utilising PTFs is a practical tool, an affordable approach, and a simple methodology for determining the properties of soil, assessing its capacity to retain water, and helping farmers manage their water resources.
