The study looked at how different types of nutrients affect the soil and nutrient levels for rice crops in a specific region. They tested organic and inorganic sources of nutrients on direct seeded rice in Bastar plateau zone. The researchers found that the recommended dose of fertilizers (NPK) had a significant impact on soil chemical properties and nutrient availability for the rice crop. Soil samples were collected before and after the growing season to analyze the nutrient content and uptake by the rice plants.
