Book Description
The Publication Deals With Green Manuring, A Subject Of Interest Not Only In Rice Cultivation But Also In Upland Agriculture, Where The Practice Is Beneficial For The Improvement Of The Physical And Biological Characteristics Of Soil As Well As For The Supply Of Plant Nutrients For Increased Crop Yields. Advantages, Disadvantages And Constraints In Adopting Green Manuring Practices Are Outlined. Labour, Time And Energy Constraints, Particularly Under Small-Farm Conditions, Are Highlighted. A Large Amount Of Available Research Data Is Reviewed In This Publication, And Future Research Needed Are Suggested. Contents Chapter 1: Introduction; Definitions, Historical Background, Potential For Green Manuring, Advantages Of Green Manuring; Chapter 2: Green-Manuring Practices; Ecological Background, Cultivation Practices, Number Of Cultivations, Method Of Sowing, Time Of Sowing, Seed Rate, Inoculation, Fertilizer Application, Irrigation, Age At Incorporation, Method Of Incorporation, Depth Of Incorporation, Interval Between Incorporation And Crop Establishment, Sub-Tropical Green-Manuring Practices, Stem-Nodulating Legumes, Azolla, Environmental Requirements Of Azolla, Management Practices For Field Cultivation Of Azolla, Genetic Improvement In Azolla, Green-Manure-Based Crop Rotations, Transported Green-Manuring Material, Green-Leaf Manuring, Alley-Cropping; Chapter 3: Accumulation Of Biomass And Nitrogen; Leguminous Green Manures, N-Accumulation In Herbage, N-Accumulation In Roots, Soil-N Versus Fixed-N, Azolla; Chapter 4: Nutrient Transformation In The Soil; Nitrogen, Phosphorus, Potassium, Calcium, Magnesium And Sulphur, Micronutrients, Organic Substances; Chapter 5: Effect On Soil Properties; Biological Properties, Microfauna, Organic Carbon, Electro-Chemical And Chemical Properties, Soil Ph, Redox Potential And Partial Pressure Of Co2, Electrical Conductivity, Physical Properties, Aggregation, Bulk Density, Water Transmission, Soil Erodibility; Chapter 6: Reclamation Of Salt-Affected Soils; Salt-Tolerance Of Green Manures, Effect Of Base-Exchange, Influence On Crop Yields; Chapter 7: Responses Of Crops To Green Manuring; Rice, In Situ Green Manuring, Green-Leaf Manuring, Intercropping With Green Manures, Dual-Purpose Leguminous Green Manures, N-Recovery And Fertilizer Equivalence, Response To Azolla, Maize, Green Manure In The Rotation, Interplanting With Green Manure, Green-Leaf Manuring, Sorghum, Wheat, Cotton, Potato, Other Annual Field Crops, Sugarcane, Residual Effects; Chapter 8: Conclusions; Constraints, Development And Research Needs.

Book Description
With the introduction of green revolution technologies, the modern agriculture is getting more and more dependent upon the steady supply of synthetic inputs. Intensive agriculture with the use of chemical fertilizers in large amount has, no doubt, resulted in manifold increase in the productivity of farm commodities but the adverse effect of these chemicals are clearly visible on soil structure, micro flora, quality of water, food and fodder. At this critical juncture, biofertilizers are useful supplement to chemical fertilizers. Organic farming has emerged as the only answer to bring sustainability to agriculture and environment. Biofertilizers is also an ideal for practicing organic farming. Biofertilizers are the most advanced biotechnology necessary to support developing organic Agriculture, sustainable agriculture, green agriculture and non-pollution agriculture. Bio Fertilizer are natural and organic fertilizer that helps to keep in the soil with all the nutrients and live microorganisms required for the benefits of the plants. Today product like biofertilizers using the biotechnology techniques have proved that biological control is widely regarded as a desirable technique for controlling insects and pests, due to its minimal environmental impact and its avoidance of problems of resistance in the vectors and agricultural pests. The increasing demand for biofertilizers and the awareness among farmers and planters in the use of biofertilizers have paved way for the fertilizer manufacturers and new entrepreneurs to get into biofertilizers production. It is one of the important components of integrated nutrient management, as they are cost effective and renewable source of plant nutrients to supplement the chemical fertilizers for sustainable agriculture. This book gives a detailed process on manufacture of biofertilizers & organic farming. It contains chapters on biofertilizers, role of biofertilizer in crop production, production and distribution of biofertilizer, organic farming, method of organic farming, weed and pest management, and many more. This book will be very helpful to soil scientists, microbiologists, biologists, students, new entrepreneurs, fertilizer industry, organization engaged in biofertilizers production, training centres and to all those interested in the efficient use and recycling of wastes, resource management and sustainable farming.
