| Theory
Soil fertility and productivity; essential and beneficial nutrient elements, criteria of essentiality, available forms, mechanism of nutrient transport to plants, functions and deficiency symptoms in plants, factors affecting nutrients availability, Microbiological transformations of C, N and S in soils; problem soils: acid, salt affected and calcareous and their characteristics, nutrients availability and reclamation (mechanical, chemical and biological). Biological method of soil fertility evaluation. Introduction to manures and fertilizers; soil test based fertilizer recommendations to crops; integrated nutrient management; factors influencing nutrient use efficiency in respect of N, P, K, S and Zn fertilizers; sources, Methods and scheduling of nutrients for different soils and crops grown under rain fed and irrigated conditions. |
