When handled separately from manures, dairy farm effluents (DE) are costly to manage because of their low nutrient content and large volume. In anticipation of using surface irrigation to lower the land application cost of DE, this projects investigated the impact, on DE characteristics, of different sources and storage systems. Milk house wastewaters were monitored on two farms using a 500 l m...

Dairy farms generate a considerable amount of manure, which is applied in cropland as fertilizer. While the use of manure as fertilizer reduces the application of chemical fertilizers, the main concern with regards to manure application is microbial pollution. Manure is a reservoir of a broad range of microbial populations, including pathogens, which have potential to cause contamination and po...

Intensification increases the environmental impact of livestock production systems. Efforts to recycle nutrients in livestock manure for crop production will effectively reduce several pollution problems, although general solutions are difficult to devise in view of the diversity in production systems, management strategies and legislation between countries and regions. This paper argues that a...

A study was undertaken to evaluate the impact of soil application spent mushroom substrate (SMS) and farm yard manure (FYM) enriched with T. harzianum on pre-emergency damping off (PED) post-emergence (POED) in chilli tomato seedlings nursery beds containing naturally infested Pythium aphanidermatum Rhizoctonia solani experimental field area Department Plant Pathology, CCSHAU Hisar during 2018-...

A pot culture experiment was conducted at the Department of Agronomy, Madras Veterinary College, Chennai, during rabi season 2019 - 2020 to study influence organic manures and synthetic fertilizers on nutrient uptake green fodder yield maize (Zea mays L.). An laid out with two factors three replications. Four manure treatments in main-plots viz., no manure, farm yard (25 t ha-1), vermicompost (...

Cultivation of an important sub alpine-alpine medicinal and aromatic herb, Angelica archangelica Linn. (Apiaceae), was carried out at two different climatic zone at 2200 m asl (Pothivasa, PV) and 3600 m asl (Tungnath, TN) altitudes in Garhwal, North west Himalaya, India. These altitudes represent temperate and alpine region of the Himalaya. Since the species has a very few wild populations, cul...

There is need for proper understanding of plant nutrients status in the soil and their requirements by various crops under different farming system. Farmers must be encouraged to make compost from residues, house refuse and other decomposable wastes available with them. If crop residues have been incorporated into the soil, care must be taken that it must be incorporated well in advance (about ...

Comprehensive control of odors, hydrogen sulfide (H2S), ammonia (NH3), and greenhouse gas (GHG) emissions associated with swine production is a critical need. The objective of this paper is to review the use of soybean peroxidase (SBP) and peroxides as a manure additive to mitigate emissions of odorous volatile organic compounds (VOC), NH3, H2S, and GHGs. Soybean peroxidase plus peroxide (SBPP)...

On a typical dairy farm today, large amounts of N are imported as feed supplements and fertilizer. If this N is not recycled through crop growth, it can lead to large losses to the atmosphere and ground water. More efficient use of protein feed supplements can potentially reduce the import of N in feeds, excretion of N in manure, and losses to the environment. A simulation study with a dairy fa...

During the rabi season of 2021, a field experiment was conducted in North Western plains Uttarakhand at Crop Research Centre, School Agriculture, Uttaranchal University, Dehradun to examine impact integrated nutrient management (INM) on lentil growth, yield, and economics (Lens culinaris Medik.). The laid Randomized Block Design with seven treatments i.e. T1 (Control, 100% RDF (Recommended Dose...
