The effects of different mulch materials applied to compacted and uncompacted soil on the quantity and the quality of deposited earthworm casts were investigated. Biochemical properties and water stability of soil aggregates were compared with the corresponding properties of worm casts. This short-time experiment was conducted in the laboratory, simulating field conditions of mulch management i...

to study the effect of different weed control methods in tomato, an experiment was conducted as completely randomized block design with three replications at the research farm of university of tehran (karaj) in 2008. the treatments consisted of post emergence (at recommended rate) or pre emergence (reduced rate in combination with mulch) application of metribuzin, rimsulfuron and sulfosulfuron,...

In this study the influence of three different tillage systems in combination with eight varying weed treatments applied within the establishment year and its effect on the final above ground leafless biomass production (after the third growing season) of short rotation coppice poplar is presented. The three tillage systems included variants with ploughing and harrowing, variants with cultivati...

The Colorado potato beetle (CPB) is an exceptionally challenging pest. Some regenerative farmers have reported that the use of transferred green manure mulch can considerably reduce CBP damage. Previous studies confirm this observation, but mainly with straw mulch, which rarely used in Central Europe, and not embedded new cropping approach. For this, six trials conducted between 2014 2019 were ...

Stale seedbeds are used by organic growers to reduce weed populations prior to crop planting. Ryemulches, derived from mechanically killed (rolled and crimped) winter rye cover crops, can serve the same purpose for spring-planted organic crops. Both methods can also be employed by conventional growers who face looming problems with herbicide resistant weeds. The objective of this research was t...

Blowing dust from summer fallow is a major soil loss and air quality concern in winter wheat (Triricum aesrivum L.) production areas of the inland Pacific Northwest (PNW). The objective of our 3-yr onfarm study in a 286-mm precipitation zone in eastern Washington was to determine the effects of tillage mulch depth during fallow on surface soil roughness, residue retention, seed-zone water stora...

This study tested the erosion mitigation effectiveness of agricultural straw and two wood-based mulches for four years on decommissioned forest roads. Plots were installed on the loosely consolidated, bare soil to measure sediment production, mulch cover, and plant regrowth. The experimental design was a repeated measures, randomized block on two soil types common in the northern Rocky Mountain...

A large part of the research carried out with strawberries (Fragaria × ananassa) has been with the aim of gaining higher yields. At the same time postharvest losses are remarkable. Therefore the need for research with the aim of increasing quality is rising. The aim of the present research was to study the influence of mulch (plastic and straw), fertilization and the age of plants (two, three a...

In recent years, North American prairie vegetation has served as a design model for highly attractive, low-cost and low-maintenance plantings in German urban green spaces. Where mixed-planting techniques, gravel mulch toppings and non-selective maintenance techniques such as mowing are used, prairie plantings are considered to be cost-effective alternative design concepts for public green space...

This study was conducted to analyze the effectiveness of using reflective mulch under stands oil palm plants several ages on intensity solar radiation reflection, growth, chlorophyll content, and photosynthetic characteristics soybeans. A nested design used, with first factor age group consisting open land aged 4, 5, 8 years. The second that included without mulch, inorganic organic mulch. use ...
