Soil potential in physicochemical properties and its impacts on sustainable land planning, Neelam River Basin, AJK, Pakistan

Soil is the primary foundation of the agroeco-system. Keeping in view such scenario, the soil potential physio-chemical properties and their impacts on sustainable land use planning over the Neelam river basin, AJK, Pakistan has been investigated. Soil potential and their physicochemical properties using the survey method at various classes of land use in the AJK regions were measured. The results of the study revealed that soil fertility was categorized into very low, low, medium, high, and very high fertility classes. The outcome of the survey showed that 66.95% sand and 23.91% soil elements were measured in the forest layer, and 37% clay elements in the subsurface layer of cultivated land. The high (58.09%) and low (49.34%) mean TP values were observed in cultivated and forest land areas, respectively. About 52.61% of Neelam valley was detected below low organic matter (OM) classification. Comparatively, a high total nitrogen nutrient (0.121%) was found high in the cultivated land. K nutrient particles 93.15 mg kg(-1) and 23.47 mg kg(-1) were recorded for cultivated and forest layers, respectively. The higher (61.54%) and lower (25.14%) values of PBS were observed for cultivated and forest land. Furthermore, Mn > Fe > Cu > Zn order of the micronutrient quantity has been recorded for all land types over the Neelam valley, Pakistan. The results of the study predicted that the potential of soil nutrients is essential for green innovation and green economic growth, which positively contributes to sustainable land use planning.
