Anaerobic thermophilic treatment of cattle manure in UASB reactors [PDF]

Waste Management & Research: The Journal for a Sustainable Circular Economy, 2002
Cattle manure was characterised after filtration through a 1-mm sieve and subsequently treated in a 9-l volume Upflow Anaerobic Sludge Blanket (UASB) reactor made of transparent PVC at a thermophilic temperature (55°C). Different Hydraulic Retention Times (HRT)(22.5, 16, 10.6, 8.9 and 7.3 days) were employed and organic matter ...

Moderate Biochar–Compost Mixture Is More Effective in Improving Biomass, Nutrient Fluxes, and Photosynthetic Outputs for Sustainable Land Restoration and Soil Fertility

Land Degradation &Development, EarlyView.
ABSTRACT Soil nutrient depletion severely constrains crop productivity in degraded and saline environments. Strategies such as biochar–compost integration could be useful for sustainable agriculture and land restoration on a global scale. This study evaluated the effects of biochar (1% Bc), compost (1% Co), and their blends (0.5% Bc + 0.5% Co and 1% Bc

Mitigation and current management attempts to limit pathogen survival and movement within farmed grassland. [PDF]

, 2007
To successfully curb microbial contamination of surface waters we need to understand, and holistically evaluate, the range of mitigation strategies that have been designed to protect watercourses from non-point agricultural sources, so as to use them to ...

Substrates with green manure compost and leaf application of biofertilizer on seedlings of yellow passion fruit plants

Semina: Ciências Agrárias, 2013
Substrates and fertilization are fundamental for seedling production, which well nourished can produce earlier and are more resistant to stresses. Animal manures are often used in non-industrialized substrates with good results, but their costs are ...

ORGANIC PHOSPHORUS FRACTIONS IN SOIL FERTILIZED WITH CATTLE MANURE [PDF]

Revista Brasileira de Ciência do Solo, 2015
Inorganic phosphorus (Pi) usually controls the P availability in tropical soils, but the contribution of organic P (Po) should not be neglected, mainly in systems with low P input or management systems that promote organic matter accumulation. The aims of this study were to evaluate the changes in the Po fractions over time in soil fertilized and not ...

Optimized Fertilization Balances Microbial Carbon and Nitrogen Use Efficiency: Evidence From Microbial Communities

Land Degradation &Development, EarlyView.
ABSTRACT Optimized fertilization involving reduced mineral N input and organic substitution can alter resource stoichiometry, microbial carbon use efficiency (CUE) and nitrogen use efficiency (NUE). However, how fertilization‐induced resource imbalance reshapes microbial community to regulate CUE and NUE remains unclear. We conducted a field experiment

Incidental phosphorus and nitrogen loss from grassland plots receiving chemically amended dairy cattle slurry [PDF]

, 2012
peer-reviewedChemical amendment of dairy cattle slurry has been shown to effectively reduce incidental phosphorus (P) losses in runoff; however, the effects of amendments on incidental nitrogen (N) losses are not as well documented. This study examined P

Using participatory scenario planning to explore the synergies and trade‐offs from upland treescape expansion

People and Nature, EarlyView.
Abstract The future of land use in the UK uplands is highly debated, with growing interest in increasing tree cover and other land use changes, alongside a desire to maintain traditional land use patterns and practices. Treescape expansion is likely to result in synergies and trade‐offs between different outcomes, so integrating stakeholder preferences

СРАВНИТЕЛНА АГРОЕКОЛОГИЧНА ОЦЕНКА НА ТОР ОТ ГОВЕДА И СВИНЕ ПО СЪДЪРЖАНИЕ НА БИОГЕННИ ЕЛЕМЕНТИ

Животновъдни науки, 2015
The aim of this paper was to study and assess a fresh and stored cattle and pig manure, for a period of 12 months by content of nutrients (N, P, K). Manure samples were collected monthly from the livestock buildings, manure storage and lagoons.

SEEDLINGS PRODUCTION AND FRUIT YIELD OF CUCUMBER ON DIFFERENT ORGANIC SUBSTRATES

Revista de Agricultura Neotropical, 2019
Demand for agricultural products with zero or reduced amounts of agrochemicals leads to increasingly healthy production alternatives. Thus, seedling formation and fruit yield of three cucumber cultivars were evaluated on different organic substrates in a
