Ammonia (NH3) losses from swine manure contribute to odor problems, decrease animal productivity, and increase the risk of acid rain deposition. This study was conducted to determine whether aluminum chloride (AlCl3) or dietary manipulation with phytase could decrease relative NH3 losses from swine manure. Twenty-four pens of nursery pigs were used in two trials, and the pigs were fed normal or...

Quantification ofnutrient andmass loss during composting isneeded ωunderstand the composting process, to implement methods for nutrient conservation, andto reduce potential adverse environmental impact. Beef cattle feedlot manure was composted in a windrow on an open concrete area in 1992, 1993, and 1994 to determine the amounts ofnutrient, C, and mass loss during composting. The area was enclo...

A pot experiment was conducted on Satla soil series in Terokhada Upazilla, Khulna during the boro season (February to June) see whether Azolla (biofertilizer) could be grown together with BRRI dhan 28 and compare effect of recommended dose N (100 kg ha-1) that different combinations urea (all treatments having doses P, K, S Zn). The laid out a completely randomized design 5 4 replications. pinn...

introduction: citrus are one of the important orchard fruit production that after banana is second in production at the world level and every year, chemical fertilizers having most important role in increasing crops productions, but in long application of fertilizers cause soil destructions and polluting underground water. also soils of dry regions are very poor in organic matter level. nowaday...

Nitrogen (N) balance has been identified as a principal agri-environmental indicator. In addition to national N balances, calculation of N balances for different agricultural regions is also recommended. In this study, national and regional net N balances for Finland were calculated. The net N balance is the result of deducting the NH3-N losses from manure and fertilisers from the gross N balan...

The problems of high nitrogen (N) fertilizer application rate and low N utilization efficiency are common worldwide in vegetable plantations. Application brown coal (BC, also known as lignite) can increase crop yield recovery (NRE). However, the effect BC on distribution exogenous soil–plant system under different fertilization strategies is unclear. pot experiment was set up three factors rand...

In order to discover the advantages and disadvantages of different fertilization regimes and identify the best management practice of fertilization in greenhouse fields, soil enzyme activities involved in carbon (C) transformations, soil chemical characteristics, and crop yields were monitored after long-term (20-year) fertilization regimes, including no fertilizer (CK), 300 kg N ha-1 and 600 k...

Nitrogen (N) availability and soil microbiota exert significant impacts on plant metabolic systems yield. Different studies have indicated that yield nitrogen use efficiency (NUE) of pearl millet (Pennisetum glaucum L.R.Br.) can be improved by the inoculation N-fixing bacteria. However, interactive effects different N sources bacteria growth, productivity, NUE been less explored. Therefore, ind...

Animal and poultry manures have been recognized for centuries as organic fertilizers providing essential nutrients to crops and improving soil structure due to their large input of organic matter. Increasing demand for poultry and egg products has led to intensification of the poultry rearing process, resulting in large amounts of poultry manure. Drying can be used to reduce the environmental i...

Soil amendments with high carbon (C) content can be effective in semi-arid regions where soils are characterized by low C. A field study was conducted 2016–2018 to evaluate the effect of char on soil chemical properties and irrigated maize (Zea mays L.) yields sandy loam fertilized urea or composted manure. Carbon-rich used a product coal combustion residue from local factory western Nebraska. ...
