Resumo:

The plastic mulch films, which are mostly made from LDPE, are used in order to increase the yields and to prevent the weed growth by covering the top of the soil by leaves or straw in nature. After a period, the mulch films turn into unmanageable quantities of soiled plastic films, which cause an environmental problem. Using degradable mulch films for agricultural purposes can be a solution for the environmental problems caused by the plastic mulch films. In this study, to introduce biodegradability to mulch films, a natural biopolymer starch was used. Before blending, starch was transformed

Three organic mulches were tested: compost, vermi-castings and woodchips, as well as an inorganic mulch, geotextile fabric, and were compared against clean cultivation.

Agronomic research is lacking for hops (Humulus lupulus), especially in North Dakota (ND) and the northern Great Plains, where demand has risen. This research was done to evaluate factors influencing hops establishment in ND. Factors for this research were hop cultivar, mulch type, and nitrogen source. Variables measured included weed suppression, soil temperature, soil moisture, hop growth, and yield. Nitrogen source did not affect hop growth. ?Cascade? outperformed ?Mt. Hood? and ?Santiam?. Mulch type affected hop establishment, weed suppression, soil temperature, and soil moisture readings.

Vegetable producers may benefit from integrating living mulches into their operations to manage weeds and improve soil quality. Living mulches, however, can reduce vegetable yield through competition. Here we investigate strip tilling into living mulches and then direct seeding a vegetable crop in the strip till zone as a production practice to limit competition. We further investigate the use of two surface-applied mulches, a newsprint hydromulch and a compost blanket, for weed control within the strip till zone. In field conditions, living mulches reduced vegetable yield by 49-84% and the us

This study describes research conducted in the laboratory and field to examine the application of vegetative mulch as daily and intermediate landfill cover. Mulch was found to exhibit stronger physical properties than soil, leading to a more stable landfill slope. Compaction of mulch was found to be significantly greater than soil, potentially resulting in airspace recovery. Degradation of mulch produced a soil-like material; d

L’Agriculture de conservation (AC) repose sur trois principes: le minimum de travail du sol, la couverture permanente du sol et la diversification des espèces cultivées. Elle a été introduite vers la fin des années 90 dans la région du lac Alaotra, Madagascar, dans l’objectif d’augmenter la productivisté de l’agriculture pluviale qui, généralement, pâtit des problèmes liés à la faible fertilité des sols, aux contraintes hydriques et à l’enherbement. L’objectif principal de la thèse consiste à quantifier et caractériser les impacts des fonctions agro-écologiques de l’AC dans l’amélioration du r

Control of water erosion of soil at mine sites requires an ability to predict the effects of different management practices on soil loss. Using soil loss models such as the Revised Universal Soil Loss Equation (RUSLE) requires calibration of the model for materials and situations that are not defined in the models handbook or software. The outer slopes of bauxite residue disposal areas are potentially highly erodible surfaces, and a recent evaluation of previous rehabilitation practices at Worsley Alumina, Collie, Western Australia, identified areas on the bauxite residue disposal areas w

Mestrado em Engenharia do Ambiente - Instituto Superior de Agronomia<br>The use of plastic mulch in agriculture had its beginning in the middle of last century and since then its use has been intensified and the costs of send this residue to appropriate final destination lead it often to be left or burned in open field, causing huge environmental concerns. The biodegradable mulch films, which can be incorporated in the soil at the end of the crop appear as a possible solution for this problem. The goal of this work was to test the biodegradability of 5 plastic mulches, made from biodegradable

Resumo:

Situated on the western edge of Africa's harsh Sahel region, Senegal faces a number of agricultural production constraints. Limited rainfall, poor soil fertility, and insufficient agronomic inputs all contribute to low yielding millet production systems. This study was initiated to assess the potential for intercropping either cowpea (Vigna unguiculata (L.) Walp.) or mungbean (Vigna radiata (L.) Wilczek) into traditional pearl millet (Pennisetum glaucum (L.) R. Br.) cropping systems. During the 2013 and 2014 growing seasons two varieties of cowpea (upright and viney), and one variety of mun
