The present investigation entitled “Effect of incorporation of crop residue on carbon pools and soil properties in Alfisol” was conducted at AICRP on Agroforestry, CES, Wakawali, Dr. BSKKV, Dapoli, Maharashtra during 2020-2021. The results of the experiment showed that the incorporation of crop residue significantly influenced the soil pH, electrical conductivity of soil, available nitrogen, phosphorus, potassium, sulphur and micronutrients viz DTPA-Zn, Fe, Mn and Cu over control and its initial status of soil. All the parameters of soil were noted declining trend with increase in depth of soil. The incorporation of Ain (Terminalia tomentosa) residue @ 5 t ha^-1 was significantly influenced the soil pH (5.71), electrical conductivity (0.27dS m^-1), avai. Nitrogen (381.00 kg ha^-1), avai. Phosphorus (27.09 kg ha^-1), avai. Potassium (492.29 kg ha^-1), avai. Sulphur (17.12 kg ha^-1) and micronutrients viz. DTPA-Zn (1.88 mg kg^-1), DTPA-Fe (21.12 mg kg^-1), DTPA-Mn (39.62 mg kg^-1) and DTPA-Cu (4.10 mg kg^-1). Almost similar trend of chemical properties were observed at 15-30 cm depth of soil. While, treatment of incorporation of Glyricidia sepium residue @ 5 t ha^-1 showed significant effect on available nitrogen (381kg ha^-1) of the soil may be due to high N content than other. However the effect of incorporation of crop residue significantly improved the yield of mustard crop.
