Corn planting methods in Virginia's residue mulch
… method of planting corn in a vegetative residue mulch seedbed which would result in stand and yields as good as obtained in planting in a conventionally prepared seedbed. Yields obtained in the first experiments in Virginia were very low because methods used in preparing the mulch seedbed, which …

Evaluating post-fire woody mulch effects on soil and stream nitrogen
… water treatability, and aquatic habitat. Woody mulch is commonly applied to mitigate soil erosion and enhance revegetation post-fire, but it also provides a source of labile carbon (C) that may stimulate microbial immobilization and limit N release from soils. The objective of our study was to …

Influence of tillage and mulch on the early growth of corn
… 1979 and 1980 to study the effect of tillage and mulch treatments on the early growth of corn plants. The objectives of this research were: (1) to separate and measure the effects of tillage and mulch on early growth of corn, (2) to determine whether observed differences in corn growth represented …

Sequential cropping of vegetables using plastic mulch, trickle irrigation, and soil fumigation
… one season utilizing trickle irrigation, plastic mulch, and soil fumigation was performed in two separate experiments. In 1980, cabbage (Brassicae olericea L. var capitata cv. Market Prize) was followed by tomato (Lycopersicon esculentum Mill cv. Pik Red). In 1981, cabbage was followed by broccoli …

Promoting pulp and paper mill material circularity: functionalised organic-inorganic cellulosic mulch films
… Conventionally, fossil-fuel-based synthetic mulch films have been used to mitigate soil water loss, as a matrix for the slow-release of fertiliser, and for UV-vis light blocking to retain water, limit nutrient loss and prevent weed growth, respectively. However, microplastics remaining from …

The effects of soil moisture, mulch, slope-facing, and surface temperature on grass seedlings
… under solar radiation than either wood-cellulose mulch or slope-facing. More growth and lower temperatures occurred at low than high moisture tensions. Mulch did not consistently benefit growth. Slope effects were evident primarily at high tensions: higher temperatures and less growth occurred on …

Reflective mulch effects on the grapevine environment, Pinot noir vine performance, and juice and wine characteristics
Reflective mulches were applied in a cool climate vineyard in Canterbury, New Zealand. Materials used were waste products: mussel shells (MS) and green (GG) and clear (CG) recycled crushed glass. A control of bare soil was also included. MS and CG were light coloured while GG and CON were dark. …

Land Use Impacts of Plastic Mulch Tomato Production and Evaluation of Sorbent Control on Shellfish Hatchery Operations
… there was also an increase in the use of plastic mulch on some of the vegetable fields on the Eastern Shore. The increased runoff commonly associated with these plastic-covered fields often contains copper-based bactericides that are used on the crops. The plasticulture fields were often located …
