Book excerpt: In the summers of 2018-19, two trials were conducted at the Hancock Turfgrass Research Center in East Lansing, MI to evaluate the viability of fraze mowing cultivation and dazomet fumigation for cool-season fairway renovations. Both trials were conducted on native and sand topdressed (TDS) blocks. In Trial 1 (Rate Study), plots were stripped with fraze mowing cultivation and dazomet was applied either; once at rates of 0, 293.7, or 588.7 kg ha-1 or twice at rates of 146.8 or 293.7 kg ha-1. Plots of Trial 2 (Disturbance Study) were subjected to 0, 15, 50 or 100% fraze mowing surface disturbance and uniformly fumigated with dazomet at 293.7 kg ha-1. Dazomet was incorporated mechanically in either Trial via Tillage or Solid-Tine (ST) cultivation and followed procedures consistent with the fumigant label. 5-days after fumigation, all plots were seeded with creeping bentgrass (Agrostis stolonifera L.) [CBG]. In the Rate Study, interval treatments provided the most consistent control of ABG emergence across seasons. Only treatments applied once at 293.7 kg ha-1 failed to yield greater CBG cover than the control. In the Disturbance Study, plots fraze mowed to 100% and cultivated by tillage achieved the greatest ABG control but poorest CBG cover. Across trials, no single treatment provided complete or acceptable control of ABG and fraze mowing cultivation impeded CBG establishment. Fraze mowing cultivation simplified the removal of surface material but did not provide acceptable ABG control at any level of surface disturbance or dazomet treatment applied.

Available in PDF, EPUB and Kindle. Book excerpt: A major concern regarding creeping bentgrass (Agrostis stolonifera) putting greens is annual bluegrass (Poa annua) invasion. With methyl bromide fumigation now being highly restricted, alternatives must be investigated to curtail weed seed soil infestations. Currently, dazomet is the only fumigant labeled for annual bluegrass control in turfgrass systems. Therefore, research questions related to dazomet efficacy come to the forefront such as how soil texture and depth of seed bank affect efficacy as well as which application rate is most effective within a soil. A study was designed to garner data as to the depth of soil removal needed to reduce annual bluegrass seedling emergence in a newly renovated putting green. Research was conducted in different seasons, summer and fall, respectively; to evaluate seedling emergence across five soil removal depths in four sampling sites. Cores were collected from four golf courses in southeastern Michigan, subdivided into different soil removal depths, potted in sterile soil media, and established in a growth chamber. Results suggest that excavating soil to a depth of 2.54 cm, or more prudently, 3.81-cm depth could minimize annual bluegrass competition in a creeping bentgrass putting green, e.g., annual bluegrass emergence was observed to be greatest in the upper soil depths (1.27 to 3.81cm) in both seasons with minimal emergence (

Download or read book Biofuel Cropping Systems written by Hans Langeveld and published by Routledge. This book was released on 2014-01-21 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Choosing appropriate practices and policies for biofuel production requires an understanding of how soils, climate, farm types, infrastructure, markets and social organisation affect the establishment and performance of these crops. The book highlights land use dynamics, cultivation practices related to conversion and wider impacts. It explores how biofuel production chain development is steered by emerging technologies and management practices and how both can be influenced by effective policies designed to encourage sustainable biofuel production. The book highlights major biofuel production chains including: cane cultivation in Brazil corn ethanol in the USA wheat and rapeseed in Europe oil palm in the Far East cane in Asia and Africa SRC and other lignocellulosic crops. In each case the development, cropping systems and impacts are discussed, system dynamics are shown and lessons drawn for the way things could or should change. Biofuel Cropping Systems is a vital resource for all those who want to understand the way biofuels are produced and how they impact other elements of society and especially how improvements can be made. It is a handbook for students, biofuel producers, researchers and policymakers in energy and agriculture.

Available in PDF, EPUB and Kindle. Book excerpt: Conservation planning involves targeted management practices and land use decision-making based on careful analysis of landscape limitations in order to protect soil and water resources. Developing solutions to conservation planning is of worldwide interest due to anticipated population growth, growing demand of feedstocks for biofuels, decreasing
