Available in PDF, EPUB and Kindle. Book excerpt: This book provides insights into recent developments in the use of mulching in agroecosystems with emphasis on the major pros and cons. Increase in human population, climatic changes and agricultural intensification have put enormous pressure on soil and water resources. As a result, we are confronted with challenges to enhance nutrient and water use efficiencies and conserve soil organic matter without compromising crop yields and food security. Increasing the soil organic matter (SOM) via residue return increased nutrient availability and soil physical and biological properties. Management practices, such as straw mulching or incorporation, have significant effects on soil health. Straw addition also increases functionality related to carbon and N metabolism via increasing the microbes and thus greatly contributes to CO2 and N2O emissions. However, the co-use of organic and inorganic fertilizer reduces the N2O emission without compromising crop yield. Mulching has long been advocated to conserve soil moisture and increase the efficiency of macro- and micro-nutrients by improving soil physical, chemical, and biological properties. These effects of mulch are translated into better crop yields while improving soil health and quality in the long run. Therefore, the use of mulching techniques is on the rise in organic as well as conventional agriculture. The book is of great interest for researchers, academics, agriculture extensionists, soil and plant scientist, fertilizer industry, farmers, agro-industrial workers, farm managers, NGOs, and climate and civil society activists.

This book was released on 2013 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Small-scale urban agriculture production has become increasingly prevalent in the United States, due to an increased availability of abandoned property and demand for locally grown products. As with most agriculture production, weed suppression is a major concern for urban growers. Mulch is ideal for managing weeds because it is inexpensive and readily available. A variety of mulches have been found successful in conserving soil moisture, moderating soil temperature, suppressing weeds, and improving crop performance. These include continuous mulches such as black plastic, and particulate mulches, such as residues from cover crops. Disadvantages of black plastic, the industry standard, include impermeability and difficulty of removal and disposal. Alternatively, newspaper end-rolls (the unprinted remains of the newspaper printing process) may be a good alternative to black plastic in that they are permeable and biodegradable. However, newspaper has a high C:N ratio which can reduce soil fertility and crop growth. The primary disadvantage of plant residue is the large quantity necessary for adequate weed suppression, but combining newspaper and plant residues may provide adequate weed suppression with reduced mulch material and a lower C:N ratio. The objective of this research was to compare two continuous (sheet) mulches, newspaper and black plastic, with and without an underlying particulate mulch of killed cover crop. Field studies were conducted in 2011 and 2012 to determine the effects of mulches on soil moisture, soil temperature, weed growth, weed removal cost, and collard (Brassica oleracea L.) performance in a low input production system. Mulch treatments were newspaper alone, black plastic alone, cover crop alone (no overlying sheet mulch), newspaper + cover crop, black plastic + cover crop, and a control (no cover crop or sheet mulch). A 60:40 mix of cowpea [Vigna unguiculata (L.) Walp.] (84 kg ha-1) and buckwheat (Fagopyrum esculentum Moench) (107 kg ha-1) was planted on June 7, 2011 and May 18, 2012, and was used based on the species' rapid growth and low C:N ratio. The cover crop treatments were killed with a tractor-mounted undercutting crimper attachment eight weeks after planting. In the sheet mulch treatments, a single layer of black plastic or two layers of newspaper were rolled over the cover crop residues or bare soil and anchored with soil and/or staples. Collards were transplanted after mulches were established at 24 plants plot-1 (August 5, 2011 and June 29, 2012). In general plots with newspaper sheet had lower soil temperature and higher soil moisture than black plastic. Adding newspaper over cover crop alone improved weed control and reduced hand weeding costs compared to cover crop alone. Plots with newspaper sheets yielded as well as plots with black plastic. The addition of a cover crop had no effect. Newspaper alone or the combination of newspaper + cover crop mulch should be considered for further research because of its positive impact on soil moisture and soil temperature and its potential to suppress weeds and improve crop performance with modifications to cover crop management practices.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Integration of different weed control methods is essential to address the financial as well as environmental concerns being faced by nursery and landscape industry. Herbicide and mulch combinations have been suggested to achieve longer weed control in nurseries and landscapes. Field and laboratory experiments were conducted to determine the effects of herbicide formulations, mulch materials, depths of mulches, and herbicide placement relative to mulches on herbicide efficacy and persistence. Two field experiments were conducted, the first in the fall of 2006 and 2007 and the second in spring of 2007 and 2008. Granular and liquid formulations of a trifluralin+isoxaben mixture were applied alone and in combination with pine nuggets and hardwood mulch at three depths, 3-, 6-, and 12-cm. Granular herbicides were applied alone (without mulch) and above the mulch; and granular-pretreated mulches were also included. Liquid herbicides were applied alone, over the mulch, under the mulch, or as herbicide-pretreated mulches. Trifluralin and isoxaben in all formulations were applied at the rate of 4.48 kg ai/ha + 1.12 kg ai/ha, respectively. Mulch alone treatments and untreated control (no mulch, no herbicide) were also included. Visual weed control ratings and weed fresh weight data were collected at 30, 60, 90, and 120 days after treatment (DAT) for the spring experiment and at 180 and 210 DAT for the fall experiment. Visual ratings were based on a scale of 0 (no control) to 10 (complete control), with 7 and above being commercially acceptable. Selected treatments from the spring experiment, including the granular formulation alone, the liquid formulation alone, liquid formulation applied under 6-cm mulches, and the liquid formulation-treated mulches at 6-cm were used to investigate herbicide persistence. Herbicide residue analysis using liquid chromatography and bioassay studies using oats and radish were part of the herbicide persistence studies. All the treatments involving 6-cm and 12-cm mulch with or without herbicides provided efficacy ratings of above 7 in both experiments. Certain combinations of 3-cm mulch and herbicides, such as granular formulation over 3-cm pine nuggets, liquid formulation under 3-cm pine nuggets, and liquid formulation under 3-cm hardwood consistently provided at efficacy ratings>̲ 7 at all evaluation dates in both studies. This could be due to the longer residual activity of herbicides in those treatments. The time-course assay of herbicide dissipation in soil indicated that herbicides applied under the mulch persisted longer compared to herbicides applied alone. Results suggested that the persistence of herbicides largely depended on the physico-chemical properties of herbicides and mulches, as well as soil moisture and temperature. Weed control with greater mulch thickness could be largely due to the physical inhibition of weed germination and growth by the mulch, whereas at lower mulch thickness, the addition of herbicides to the mulch treatments was necessary to provide weed control equivalent to the thick mulch layer. Mulches applied at the 12-cm depth are expensive and can be detrimental to health of desirable plants, even though it provided almost complete weed control. Depth of mulches could be reduced to 3-cm from commercially recommended depths of 5- to 8-cm when herbicides were combined with mulches.
