Mulching is used to improve the condition of agricultural soils by covering the soil with different materials, mainly black polyethylene (PE). However, problems derived from its use are how to remove it from the field and, in the case of it remaining in the soil, the possible effects on it. One possible solution is to use biodegradable plastic (BD) or paper (PP), as mulch, which could present a...

The constraints associated with peat use in horticulture has led to a search for alternative materials their as growing media. organic derived from palm trees (composted or not) can constitute an due ligneous and fibrous character, similar coir fiber. This work studies the feasibility of using several palm-tree-derived (Phoenix dactylifera L.) media ingredients transplant production lettuce (La...

Sweet-scented geranium (Pelargonium graveolens L'Hér), a plant belonging to the Geraniaceae family, has medicinal and aromatic properties and is widely used in the cosmetic, soap, perfume, aromatherapy, and food industries. The aim of this study was to evaluate the influence of fertilization and the use of different colors of plastic mulch on sweet-scented geranium biomass and essential oil. Th...

A two year (2010-2012) study was conducted to assess the effects of different agronomic management practices on the emissions of CO2 from a field of non-irrigated wheat planted on China's Loess Plateau. Management practices included four tillage methods i.e. T1: (chisel plow tillage), T2: (zero-tillage), T3: (rotary tillage) and T4: (mold board plow tillage), 2 mulch levels i.e., M0 (no corn re...

Mulch applied to tropical soil may increase soil health both through stimulation of microbiota beneficial to plant nutrient uptake and the suppression of plant disease. To test this hypothesis, we compared beans in three cropping systems: (1) mulched with secondary vegetation (slash/mulch), (2) mulched with foliage from alleycropped nitrogen-fixing trees, Calliandra calothyrsus, Gliricidia sepi...

Multilayer routing is an important problem in the physical design of integrated circuits as technology evolves towards several layers of metallization. MulCh is a channel router accepting specification of an arbitrary number of routing layers. Though several other channel routers for three layers of interconnect have been proposed, the only previously reported practical implementation for an ar...

This paper reports on the thermal characterization, via the thermal conductivity, of natural materials, such as mulch and lava rock and their usefulness as building insulation. Experiments were carried out using a scale one monitored wall (i.e. heat flux and temperature sensors) exposed to a heating source on one side and to an air conditioned space on the other. The wall system was composed of...

The problem of degradation of agricultural residues from palm oil industry is increasing due to its expansion. Lignocelloulosic waste from these industry represent large amount of unutilized resources, this is due to their high lignin content. Since white rot fungi are capable of degrading lignin, its potential for the degradation of lignocelloulosic waste from palm oil industry was accessed. T...

Cellulolytic fungi have shown potential applications in various industries such as pulp and paper, agriculture, biofuel production, textile. The purpose of this is study to isolate, screen identify cellulolytic from palm. Twenty (20) strains were isolated screened. Seven (7) isolates: 3 Aspergillus spp, (2) Trichoderma 1 Rhizopus species, Penicillium spp had significant activity. C (from palm p...

A ®eld experiment was conducted during the dry season of 1993/1994 at the Irrigation Research Farm, Institute for Agricultural Research, Samaru, Nigeria to evaluate water management options on the performance of tomato. The trial involved three furrow irrigation methods (conventional furrow, conventional furrow with cutback, and alternate furrow), two mulch treatments (without mulch and straw m...
