Assessment of physico-chemical and chemical properties of soils under turmeric growing sites of Nizamabad District, Telangana

Abstract

A detailed soil survey was conducted in major turmeric growing soils of Nizamabad district Telangana state to examine the physico-chemical and chemical properties of soils. Soil samples (40 surface and 40 subsurface) were collected at a depth of 0-15cm and 15-30cm. Collected soil samples were analyzed for their physico-chemical properties (pH, EC, and OC) as well as chemical properties, including available nitrogen (N), phosphorus (P), and potassium (K). The pH of the soil was slightly acidic to slightly alkaline (6.2 – 8.6) in nature and the EC was non saline (0.08 – 0.54 dS m-1) suitable for all crops. Organic carbon was found low to medium (3.60 to 8.50 g kg-1), these soils had low to medium nitrogen levels (101.20 – 389.50 kg ha-1) Phosphorus (14.69 – 69.97 kg ha-1) and potassium (114.80 – 356.80 kg ha-1) were found low to high in ranges.
