Biomass allocation is an important plant trait that responds plastically to environmental heterogeneities. However, the effects on this trait of pollutants owing to human activities remain largely unknown. In this study, we investigated the response of biomass allocation of Phragmites australis to petroleum pollution by a ¹³CO₂ pulse-labelling technique. Our data show that plant biomass signifi...
The lack of cover is one the main accelerators soil degradation. Without protection and exposed to rainfall, breaks particles, causing surface sealing, making infiltration difficult. This study characterizes sealing hydraulic erosion in Ultisols Alto Ipanema Basin. Eight plots were established under treatments: bare with Brachiaria decumbens mulch. Three rain events simulated at 24-hour interva...
Intensive tillage will continuously reduce soil quality, characterized by decreased C-organic. Low C-organic indicates the disturbance of fertility. More conservative management experiments have been done for seven years to restore quality sugarcane (Saccharum officinarum L.) productivity. This research aimed study effect system, bagasse mulch, and their interactions on chemical properties agro...
A regional assessment of the ecological effects of chipping and mastication fuels reduction and forest restoration treatments. Project Title: A regional assessment of the ecological effects of chipping and mastication fuels reduction and forest restoration treatments. ABSTRACT: Over the past several years, fire managers have increased their use of mastication treatments, the on-site disposal of...
crop residue is a non-chemical method of weed control in agricultural sustainable systems. this research was conducted at the alarogh site of ardabilto evaluate the effect of integrated use of mulch and herbicide on weed emergence and growth in potato in 2007. treatments were four levels herbicide including: (1) paraquat [n,n'-dimethyl-4,4'-bipyridinium dichloride] herbicide as pre-pl...
in order to study the effects of cropping systems and mulch application in relay intercropped styrian pumpkin (cucurbita pepo l.) with chickpea (cicer arietinum l.), a field experiment was conducted as factorial layout based on a randomized complete block design with three replications at the agricultural research station, college of agriculture, ferdowsi university of mashhad, during growing s...
North American prairie vegetation has been a role model for designing highly attractive plantings for German urban green spaces for the past decade. In combination with gravel mulch top layers on planting sites and non-selective maintenance techniques like mowing or burning, prairie plantings are considered to be cost-effective and low-maintenance. This study was undertaken to assess the impact...
food quality, marketability, soluble solids, size and color of nectarine fruit is affected by the intensity and amount of direct sunlight. usually the outer areas of fruit trees get enough light and take the appropriate color. however, in the middle and lower part of trees, due to low light intensity, fruits have no good color and taste and their marketability were not desirable. to improve the...
effects of nitrogen fertilization timing close to the beginning of short-day period and white mulch on flowering and yield components have been studied in ‘paros’ and ‘queen elisa’ strawberry cultivars. split plot experiment in a randomized complete block design with eight treatments (two mulch treatments × n fertilization during four different times from last week of august to third week of se...
