The changes in the structural characteristics of biomass residues during pyrolysis and composting were investigated. The biomass residues particles were prepared by pyrolysing at temperatures ranging from 350 to 400. For soilless production of the ornamental plant Anthurium andraeanum, pure sphagnum peat moss (P) has traditionally been used as the growing medium. This use of P must be reduced, ...

During oil-sands mining all vegetation, soil, overburden, and oil sand is removed, leaving pits several kilometers wide and up to 100 m deep. These pits are reclaimed through a variety of treatments using subsoil or a mixed peat-mineral soil cap. Using nonmetric multidimensional scaling and cluster analysis of measurements of ecosystem function, reclamation treatments of several age classes wer...

In high-latitude ecosystems climate change induced plant community shifts towards dominance of shrubs and trees will potentially have large consequences for soil carbon dynamics. Changes in the litter layer due to an altered quantity and quality of litter input, or by its indirect effect on microclimatic conditions, might affect the decomposer community. To be able to predict the effects of inc...

The positive effects of biochar applied as soil conditioner for boosting fertility and thus plant growth are sufficiently documented, mostly through in-situ experimentation. This field study evaluated the amendment (5% v/v) with distinct types (biosolids-derived biochar, BDB; cattle manure-derived MDB; spent coffee grounds-derived SCGDB) on growth, physiology quality attributes lettuce ( Lactuc...

Chironomid midges are amongst the most abundant and diverse holo­ metabolous insects of the Antarctic and sub-Antarctic. Eretmoptera murphyi Schaeffer, 1914, has been enigmatic to systematists since the first discovery of adult females on South Georgia. The rediscovery of the species as a suspected introduction to Signy Island (South Orkney Islands) allows the description of the immature stages...

Origanum acutidens (HAND.-MAZZ.) IETSWAART is a promising ornamental plant that can be widely used in landscape management. It is endemic to Eastern Anatolian region of Turkey. Tissue culture has not been used to micropropagate it. The study reports stem node explants from one-week-old seedlings of the plant for successful micropropagation. The stem nodes were cultured on MS medium containing 0...

The physico-chemical characteristics as well as chemical composition of Arachis hypogaea shell (AHS) ash were evaluated by different techniques such as X-Ray fluorescence, X-Ray diffraction and thermo-gravimetry. The material, which is considered a by-product obtained from Groundnut shelling, was investigated as a potential fertilizer, energy source and as animal feeds. And this will provide a ...

For clean a agriculture and safe environment, this study was conducted, which included the preparation of compost from Prosopis fracta Alhagi maurorum plants, evaluation Its as medium for tomato seedlings production comparing it with peat moss, an organic fertilizer in comparison number fertilizers - poultry wastes, cow sheep wastes spent mushroom residues, results showed superiority prepared o...

Objective: Evaluate the effect of three types substrate and different shoot lengths onthe rooting Carica papaya L. shoots.Design/ methodology/ approach: This experiment followed a completely randomizeddesign with 2×3 factorial arrangement. Shoots 30 40 cm length werecollected in March 2018 from lateral branches plants (Carica L.)native to various regions Guerrero. were placed substrates: 1)sand...

An experiment was conducted on the topic “A study vertical gardens in urban areas’’ during rainy season 2021-22 at Research Field of Department Horticulture, Sam Higginbottom University Agriculture, Technology and Sciences, Prayagraj. The observations were recorded various growth parameter. Vertical are becoming a common component contemporary garden designs living spaces because shrinking land...
