Impacts of felling, mulching, and burning on budgets of C, N, S, P, K, Ca, and Mg; rates of CO2 evolution from the soil; soil seed storage; and plant growth were evaluated. The felled tropical evergreen forest was 8-9 yr old, interspersed with patches of 70-yr-old forest and had a leaf area index of 6 and aboveground biomass of 5.2 kg/M2. Harvest of the largest trees removed 18% of the S, and >...
The study compares energy production from semi-natural grasslands by the integrated generation of solid fuel and biogas from biomass (IFBB) through mechanical separation of the biomass with the dry fermentation (DF) and hay combustion system (HC). In addition, traditional use for beef cattle production and non-refining systems of landscape conservation, i.e. mulching and composting, are conside...
This study investigates the influence of blade lifting angles, tractor forward speed, and power take off (PTO) speed on degree mulching. Four blades with different two PTO speeds, three speeds were assessed using parametric test at Universiti Putra Malaysia oil palm plantation. The result shows that best-fit regression equation was a quadratic high coefficient determination. It indicates any ch...
Film mulching is an effective water-saving and yield-increasing measure for potato production in Northwest China. However, the response mechanism of microbial communities to films soil still unclear. In this study, polyethylene film (PM), biodegradable (BM), liquid (LM), non-mulching (NM) were applied on drip-irrigated investigate effects bacterial fungal through DNA sequencing, Pearson correla...
Mulching the soil with organic-based formulations (hydromulching) is a sustainable alternative to plastic mulching that here hypothesized maintain crop production under drought stress by hormonal and metabolic regulation of source–sink relationships. To test this hypothesis, artichoke plants were grown on non-mulched mulched polyethylene three different organic mixtures, subjected optimal reduc...
Source reduction efforts have helped to keep waste generation rates under control. The state of the economy has a direct impact on consumption and waste generation. With the strong economic growth that has occurred throughout the 1990's, waste generation has continued to increase. Despite this, the total per capita waste generation has remained unchanged from 1997 to 1998. On-site yard waste co...
Potato is an important crop in the Northwest China, however, its production constrained by water scarcity. Plastic mulching film efficient technical measure to alleviate potato restrictions. Therefore, studying response of yield and use efficiency plastic great significance. The study conducted a meta-analysis quantify effect on Northwest. then quantified effects different levels natural condit...
Lack of adequate seed-zone moisture is a major problem in the timely sowing of wheat (Triticum aestivum L.) after maize (Zea mays L.) in rainfed areas of north-west India. Field experiments were conducted during 1993±1997 in an acid Al®sol (typic Hapludalf) in north-west India to conserve rainwater in situ by using four combinations of mulch and tillage practices, and using the conserved moistu...
The physical and chemical properties of composite starch-based films containing cellulosic fiber, chitosan, and gelatin were investigated. Films containing both cellulosic fibers and chitosan demonstrated tremendous enhancements in film strength and gas permeation. The water absorbency of composite films could be greatly reduced in film composites containing cellulosic fibers and gelatin, but t...
