Acacias are invasive Fabaceae species that can be composted to produce organic amendments and horticultural substrates. With this aim, big piles were set up with ground and screened acacia residues and pine bark, and managed with different turning frequency, to analyze the physicochemical...

Aims: In order to explore the main reasons and the invasive processes of water hyacinth (Eichhornia crassipes) in the dike-pond district in southern China, we reviewed and comprehensively analysed the historical documents and files on the water hyacinth concerning the latest research progress on...

Reduction of soil fertility is a key factor for restoration of species-rich grasslands. However, when soil fertility is already low, a further reduction may reduce flower size and weight. Low fertilization rates could then enhance grass production and enlarge the size of the flowers of grassland...

Acacias are invasive Fabaceae species that are highly competitive and a serious threat to local biodiversity and natural habitats. Taking into account their high availability and low cost, a valorization approach for acacia shrubs may be composting to produce horticultural organic amendments and...

Due to the increasing of wood as energy renewable resource in power and heat plants the amount of wood ash as waste will increase. Wood ash contains plant macronutrient elements P, K and different elements as micronutrients, only organic and nitrogen are missing. Wastewater sludge from small...

The ecological aspects pertaining to floral diversity, cropping systems and crop diversification of an organic farm CSKHPKV, Palampur were studied. The data for two years, that is, 2006-07 and 2007-08 was analyzed. The initial recorded data pertaining to various activities in the organic farm...

In search of less toxic and ecofriendly alternative of disease management seed treatment was done with Trichoderma @ 4 gm/kg and soil application of neem cake, mustard cake and karanj cake. The result revealed, under natural condition, that all the organic amendment significantly increased seed...

Waste materials, and materials derived from wastes, possess many characteristics that can improve soil fertility and enhance crop performance. These materials can be particularly useful as amendments to severely degraded soils associated with mining activities. This study evaluated biosolids,...

In a 10-year study, we assessed the influence of five carbon (C) treatments on the labile C and nitrogen (N) pools of historically N-enriched plots on the Shortgrass Steppe Long Term Ecological Research site located in northeastern Colorado. For eight years, we applied sawdust, sugar, industrial...

Bauxite is processed in alumina refineries by the Bayer process in which Al-containing minerals are dissolved in hot NaOH. The insoluble solids (bauxite processing residue mud and sand) are washed, sometimes partially neutralized (using CO₂ or seawater treatment), and deposited in impoundments...
