The fungus Agaricus bisporus is commercially grown for the production of edible mushrooms. This cultivation occurs on compost, but not all of this substrate is consumed by the fungus. To determine why certain fractions remain unused, carbohydrate degrading enzymes, water-extracted from mushroom-grown compost at different stages of mycelium growth and fruiting body formation, were analyzed for t...

The effect of successive applications of urban compost (up te 150 and 400 t ha-1 during eight years) en the status ef phosphorus in a calcareous soíl (20%) was testad in a greenhouse experimento An 6-15-15 complex fertiliser was also applied for comparison. Five years of ryegrass and three of horticultural plants (tomate and eggplant) were successively cropped during the experimento Increases o...

this experiment was conducted in order to study the influence of different levels of municipal solid waste compost and nitrogen rate on grain quality of sweet corn (zea mays l. saccharata) and some soil properties under marvdasht conditions during growing season of 2008-2009. the experiment was arranged as split plots based on a randomized complete block design with two factors and three replic...

Chemical ripening of sugarcane is an important component to profitable sugar production in the United States as well as other sugarcane industries throughout the world. Harvesting of sugarcane often begins before the sugarcane reaches the desirable maturity level. This is especially true in the Louisiana sugarcane industry where the window for harvesting is limited because of the risk of freezi...

Manure or compost from beef cattle feedlots can be excellent sources of nutrients and organic matter when added to soils. This study was conducted to determine the effect of a single application of manure and compost on runoff and erosion under no-till and tillage conditions. Tillage consisted of a single disking operation up and down the slope on a Sharpsburg soil which was cropped to grain so...

The remarkable influence of organic inputs, such as manure and compost, on dN values of growing plants suggests the possible use of N natural abundance as a tracer of N. Thus, using N natural abundance might be possible to estimate compost-N recovery as an alternative method to the use of N-enriched materials. The objective of this study was to verify the feasibility of using dN value to esti...
