A stable compost is needed in plant growth media. However, when compost is land applied, its effect is through the initiation and acceleration of microbial processes leading to the production of soil stabilizing agents. It was proposed that there is an optimum degree of maturity of compost used for land application, a degree characterized by the reduction of the labile organic matter to a point...

The recycling of livestock manure in cropping systems is considered to enhance soil fertility and crop productivity. However, there have been no systematic long-term studies of the effects of manure application on soil and crop macro- and micro-nutrients, heavy metals, and crop yields in China, despite their great importance for sustainable crop production and food safety. Thus, we conducted fi...

Establishing a simple yet reliable compost stability test is essential for a better compost quality control and utilization efficiency. The objective of this study was to examine the relationship between extractable organic carbon (OC) and compost stability based on 18 compost samples from five composting facilities. The compost samples were extracted sequentially with water for 2 h [water(2h)]...

COMPOST is the result of our first reflections on the computing requirements for synthetic speech generation. It combines the basic facilities of a rule-oriented software with object-oriented design. COMPOST is a tree compiler : it manipulates and transforms not only lists of atoms but also trees and subtrees. Basic atoms involved into the tree inherit of properties of user defined classes Feat...

When feedlot pens are scraped in the spring and summer, manure is often stored before land application can occur in the fall. Manure stockpiled or composted was evaluated for nutrient losses in 2 experiments for 104 (Exp. 1) and 111 d (Exp. 2). Stockpiles (n = 2 in Exp. 1 and n = 3 in Exp. 2) and compost windrows (n = 6 in Exp. 1 and n = 4 in Exp. 2) were constructed with feedlot manure scraped...

The objective of this series of studies was to investigate the use of compost and mulch materials in erosion control and stabilization projects. The first phase of the study primarily looked at the impacts of surface blankets of twelve different compost and mulch materials on total solids (TS) loss and water quality and found that mulch blankets produced runoff with the lowest TS and nutrient c...

We evaluated the abundance of microbial functional groups involved in compost fertility, and the chemical parameters of maturity and quality most commonly analyzed in compost products. We employed compost produced using the same hydrolytic stage and two maturation processes (with and without earthworms) and with different organic wastes. Our aim was to propose a valid tool for measuring the qua...

Improper use of urea may cause environmental pollution through NH3 volatilization and NO3 (-) leaching from urea. Clinoptilolite zeolite and compost could be used to control N loss from urea by controlling NH4 (+) and NO3 (-) release from urea. Soil incubation and leaching experiments were conducted to determine the effects of clinoptilolite zeolite and compost on controlling NH4 (+) and NO3 (-...

H ighbush blueberry (Vaccinium corymbosum L.) is adapted to soils with high organic matter and pH of 4.5-5.5. Coniferous sawdust is the blueberry industry standard soil amendment and mulch in the Pacific Northwest, USA. However, sawdust prices are increasing, and its availability is becoming limited. Therefore, many blueberry producers are interested in compost as an alternative to sawdust, whi...

Fertilization plays an important role in crop growth and soil improvement. This study was conducted to determine the best fertilization system for wheat production. Experiments were arranged in a complete block design with three replications in two years. Main plots consisted of six methods of fertilization including (N1): farmyard manure; (N2): compost; (N3): chemical fertilizers; (N4): farmya...
