A statistical approach to evaluate compost genotoxicity
Parallel experiments were carried out to evaluate the induction of genotoxic effects in Vicia faba seedlings treated both with aqueous and organic extracts (dimethyl sulphoxide 5%) of 13 composts, or grown on soil samples to which different doses of the same composts were added. Pearsons linear correlation coefficient and multiple regression were used to study how these two different ...

Compost maturity as expressed by phytotoxicity and Volatile organic acids
VOA in Composts Maturity is a qualitative trait of compost that may be expressed in a number of ways and is generally held to be relevant to plant performance. Volatile organic acids (VOA) have been cited to be responsible for phytotoxicity (plant growth suppression) when immature compost is used for growing plants (Manios et al., 1989). However, the production of VOA in compost has not been ...

Potential utilisation of pulp and paper mill biosolids in composting and plant production: a case study at St. Marys Papers Ltd. (Canada)
The use of St Marys Paper biosolids as a soil additive or growth cover was investigated. Biosolids were mixed with a commercial potting media in five vol/vol ratios and employed in a greenhouse study. The biosolids were found to improve Pinus banksiana seedling growth, a 50% biosolids:50% ProMix mixture yielding the tallest plants and highest dry mass. To further biologically stabilise the ...

Fertilization of pinus pinea L. seedlings with a sewage sludge-based compost
Two experiments were conducted to evaluate the effect of a sewage sludge-based compost (SSC) on the growth and mineral composition of containerized Pinus pinea L. seedlings. In the first experiment, five different substrates were tested: four binary mixtures of SSC and peat (100% SSC, 75% SSC, 50% SSC and 25% SSC, by volume) without fertilization, and a control substrate (peat-based substrate + ...

What are the advantages of using rabbit manure as organic fertilizer?
Nutrient content of rabbit feces Rabbit manure is a kind of high efficient organic fertilizer, the content of nitrogen, phosphorus and potassium is significantly higher than other animal manure. The nitrogen content of rabbit manure is 1.53 times of chicken manure, 3.29 times of sheep manure, 3.83 times of pig manure, the phosphorus content is 2.88 times of chicken manure, 4.6 times of sheep ...

What are bioplastics and where are they used?
Bioplastics are biodegradable plastics. They will typically break down completely in three to six months whereas regular plastics can take up to 1000 years to break down to the same extent. Biodegradable plastics could play a key role in helping to solve the problem of plastic wasted. Here, plastic manufacturing specialist Ansini provide a quick guide to what you need to know. Understanding the ...

How three U.S. mini-farms are sowing the seeds of global food security
Tiny, biointensive operations show smallholder farmers from around the world how they can grow far more food than conventional approaches. Her face shaded by a wide-brimmed straw hat, Olawumi Benedict is cheerfully tending to her “little babies” — kale seedlings growing in shallow wooden flats until they’re hardy enough for transplantation into soil beds. Three miles over ...

cheap 50 72 128cell trays wholesale supplier
Due to the need for higher temperature, it is necessary to sprinkle some warm water on the leaves regularly. Plants placed in a dry environment can put a layer of wet small gravel in the flower pot to promote the growth of plants. Seedlings are planted from March to April in spring, or preferably from September to October in winter. Sowing before the frost season. In winter, please manage ...

What raw materials can be used to produce organic fertilizer
Organic fertilizer is a kind of organic material fermented by microorganisms, such as plant residues, animal manure, organic by-products of processing industry, which can be applied to the soil to provide plant nutrition. Organic fertilizer can provide comprehensive, stable and long-term nutrient elements for plant growth, improve soil structure, improve soil buffering performance, water and ...

Is Conservation Tillage the Future of Agriculture?
Like any business, farmers must manage their farms with one foot in the present and the other in the future. It’s not enough to focus just on yields. We must also consider the impact those yields have on our fields. To ensure sustainable crop production, the implementation of a method like conservation tillage is vital. Conservation tillage is a tilling process that leaves at least ...
