Patent / Technologies / Methodologies / System etc. (Upto Five) :

  1. Granted COPYRIGHT (Copy Right No. SW-8955/2016) for development of Computer based Software for Decision Support System (DSS) for On-line assessment of Soil Health by Indian Copyright Office, Ministry of Human Resources, Govt. of India.
  1. Medium duration no-till (10 yr) combined with short intervals of conventional tillage (3 yr) followed by long-term no-till emerged as novel technology to sequester more soil organic carbon (SOC) as compared to continuous long-term no-till under wheat.
  1. For the first time Brassica carinata cv. DLSC 1 had been identified as the most promising phytoextractor for Zn, Pb and Ni, while Brassica juncea cv. Pusa Bold for Cu.
  1. The PCA with non-linear scoring functions emerged as the best protocol for development of SQIs. Established the critical limits of indicators and indices of soil quality in rice-rice cropping systems under Inceptisol, Entisol, and Alfisol.
