Developing integrated farming systems is critical to reducing the environmental impact of animal production. Traditionally, this has been through integrating animal and feed or plant production. But that has become increasingly difficult as agricultural production has become regionally specialized leading to the spatial separation of animal and feed production. This spatial separation has led t...

A new generation of small scale (less than 20 MWe) biomass fueled, power plants are being developed based on a gas turbine (Brayton cycle) prime mover. These power plants are expected to increase the efficiency and lower the cost of generating power from fuels such as wood. The new power plants are also expected to economically utilize annual plant growth materials (such as rice hulls, cotton g...

Aluminum toxicity is a major limitation to leguminous crop production in acidic soils but mineral and organic fertilizer applications could ameliorate the condition. Thus, focus of this study was evaluate influence manures on post-harvest soil fertility quality, yield agronomic efficiencies soybean (Glycine max). The had six treatments: poultry manures, rabbit pig sheep cattle single super phos...

Organic manures are more preferred and environmentally friendly than chemical fertilizers for minimally contaminating soil, water environmental resources, but the determination of right source organic continues to remain an unexplored aspect. Considering important issue, a multi-year field trial was carried out determine response forage soybean four sources nutrients such as (IF), poultry litte...

The organic source of nutrients would be a promising practice for Valeriana jatamansi cultivation which maintains its curative value. A set experiments was conducted at Hill Zone West Bengal, Kalimpong two consecutive cycles to standardize nutrient management in V. optimum growth and economic yield. Different sources such as farm yard manure (FYM), bio-fertilizer (BF), vermicompost (VC) were ap...

The ground cover produced by green manures has a direct influence on weed suppression and, in addition, the biomass these same plants influences crop growth. This study was carried out to compare effect of manure species incidence weeds, sequence, order evaluate effects use productive characteristics maize plants. A completely randomised experimental design used, with 11 treatments and 4 replic...

This chapter considers the emissions of ammonia (NH 3) and nitrous oxide (N 2 O) from the excreta of agricultural animals deposited in buildings and collected as either liquid slurry or solid manure. This includes emissions from animal excreta at all stages: animal housing, manure storage and from land spreading of manures. Excreta deposited in fields by grazing animals are dealt with under SNA...
