Effect of Urban Waste Compost Leachate on the Soil Physical, Hydraulic, Moisture Characteristics and Corn Yield
Compost leachate is a liquid resulting from physical, chemical and biological decomposition of organic materials. The main objective of this study was to evaluate the influence of leachate compost on the physical, hydraulic and soil moisture characteristic curves. Also, the effect of leachate on the aerial organ fresh weight of corn was investigated. Leachate was added to clay loam and sandy cl...
متن کاملSimulating urban waste compost effects on carbon and nitrogen dynamics using a biochemical index.
Composting has emerged as a valuable route for the disposal of urban waste, with the prospect of applying composts on arable fields as organic amendments. Proper management of urban waste composts (UWCs) requires a capacity to predict their effects on carbon and nitrogen dynamics in the field, an issue in which simulation models are expected to play a prominent role. However, the parameterizati...
متن کاملWASTE MANAGEMENT Soil Properties as Influenced by Phosphorus- and Nitrogen-Based Manure and Compost Applications
posting has some disadvantages that include nutrient and C loss during composting, the cost of land, equipManure or compost application based on N needs of corn (Zea ment, and labor required for composting, and odor assomays L.) may result in soil accumulation of P, N, and other ions, ciated with composting. since the manure or compost N/P ratio is usually smaller than the corn N/P uptake ratio...
متن کاملMicrobial Dynamics and Fertility Characteristics in Compost from Different Waste and Maturation Processes
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...
متن کاملMeasuring and Simulating 2,4-D Residues in Silty Clay Soil Profile Under Two Water Regimes Using a LEACHP Model
The extensive use of pesticides in agriculture is compromising soil and water quality. One major concern is protecting water resources from contamination. The main objective of this research was measuring 2,4- D in a silty clay soil and simulating temporal transportation of this herbicide in soil using a LEACHP model, in a corn root zone field. 2,4- D was applied at 3.5 kg a.i./ha, followed by ...
