|Soil is an important components of the environment that supports many forms of life. It is a complex mixture of solid, liquid, and gaseous substances, and plays a vital role in crop production, environmental pollution, and human health.In this study, we examined the effects of five fertilization treatments-no fertilizer (CK), straw return (SR), chemical fertilizer (NPK), and green manure (GM)-on soil pH, SOC, TN, C/N ratio, and available nutrients (AN, AP, and AK) in the ploughed layer (0–20 cm) of 5 different crops like Wheat, Rice, Maize, Sugarcane, Soyabeans in 7 fields in in Betul District, Madhya Pradesh. The results show that CK (5.38 units) had the lowest soil pH, whereas NPK (5.97 units) and OM (5.63 units) were higher (P,0.05). OM treatment had the highest C/N ratio, 9.66 to 10.98 (P,0.05). Thus, by using NPK (Chemical Fertilizer) that it boosts soil fertility in this location. Our finding shows that the both Inorganic type fertilizers, when applied properly, may provide plants the vital nutrients they need to develop and produce. The potential effect on crops is influenced by a number of variables, such as the kind of fertilizer used, the pace at which it is applied, the soil's characteristics, and the crop's needs.
