Previous studies have reported that tractors are responsible for high proportions of fatal and nonfatal agricultural injuries. However, many common and preventable risk factors, conditions, and ...associated costs related to tractor-related injuries have not been investigated. This case-based study used workers' compensation data to investigate tractor-related injuries. The objectives of this study were to (1) identify and describe tractor-related injuries, (2) assess medical and indemnity costs associated with tractor-related injuries, and (3) determine contributing factors associated with those injuries. Tractor-related injury claims data from Colorado workers' compensation records were analyzed for a 12-year period (1992-2004). Descriptive analyses of the costs, characteristics, and contributing factors associated with tractor-related injuries were conducted. The epidemiological agent-host-environment model was used to analyze injury event descriptions. A total of 23,484 agricultural-related injury claims were analyzed. Through an event description analysis, a total of 642 claims were identified as being tractor-related. Over 60% of tractor-related claims involved sprains/strains and contusions. A total of 21% of tractor-related claims were associated with the worker mounting or dismounting a tractor, and an additional 10% of claims were associated with the worker falling, jumping, or slipping off a tractor. Among all claims associated with tractor mounting or dismounting, 35% involved the ankle and 15% involved the knee. Nearly three-quarters of tractor-related claims were medical-only claims. The median medical claim cost was $319, and the median medical plus indemnity claim cost was $335. Claim costs associated with tractor-overturn injuries were higher than tractor-related injury claims in general. This study determined that a large percentage of tractor-related injury claims were associated with tractor mounting and dismounting. These findings are consistent with previous research and suggest the need to further investigate tractor design criteria related to mounting and dismounting.
If you are familiar with the musical “Fiddler on the Roof,” this approach was used to balance “traditional” decision-making with the use of the term (on the other hand) to develop and explore new and ...better ways to make decisions. Land pays for itself over the long term through the cash flow generated from rent or crops and asset appreciation over time. Utilizing your existing cash to make a sizable down payment on the purchase could lead to cash-flow problems, like not having money available for repairs, inputs or other urgent expenses. Given the size of the business, an incremental $38,000 purchase, if 100% debt-financed, would nominally impact the balance sheet.
Yoğun tarla trafiği kaynaklı toprak sıkışması, suyun infiltrasyonunu, kök gelişimini ve ürün verimini azaltırken,
toprağın hacim ağırlığı ve toprağa giriş direncini artırmaktadır. Bu çalışmanın ...amacı, mısır yetiştirilen bir tarlada silaj
ekipmanlarının kullanılmasından önce ve sonra toprak penetrasyon direncinin yersel değişim paternlerindeki değişimleri
belirlemektir. Toprak penetrasyon direnci 100 × 400 m'lik tarlada hasattan hemen önce ve sonra 10 m'lik aralıklarla
ölçülmüştür. Ölçümler herbir transect boyunca sıra üzeri ve sıralar arasında üst 20 cm'lik toprak katmanında
kaydedilmiştir. Hasattan önce ve sonra 1353 ölçümün ortalama penetrasyon direnci sırasıyla 2097 kPa ve 3116 kPa'dır.
Hasat sonrası çalışma alanının ortalama hacim ağırlığı 1.14 g cm-3'den 1.46 g $cm^{-3,}$e yükselirken, ıslak agregat stabilitesi
% 33.4'den % 17.9'a düşmüştür. Çalışma alanında 1'er m aralıklarla toprak penetrasyon direnci dağılım haritalarını
hazırlamak için nokta kriging analizi uygulanmıştır. Hasat sonrasında toprak penetrasyon direnci değişim paternleri
hasat öncesi değişim paternlerinden önemli ölçüde farklılıklar göstermiştir.
Soil compaction caused by heavy wheeling reduces water infiltration, root development, and yield, and increases
bulk density and soil strength. The objective of this study was to determine changes in spatial variability patterns of soil
penetration resistance before and after using the silage machine in a corn-growing field. Soil penetration resistance was
measured in a 100 × 400 m field with 10 m intervals just before and after harvesting. Measurements were taken from the
20 cm top layer on rows and inter-rows throughout each transect. The mean penetration resistance of 1353 measurements
before and after harvesting was 2097 and 3116 kPa, respectively. Average bulk density within the field increased from 1.14
g $cm^{-3},$ to 1.46 g cm-3, but wet aggregate stability decreased from 33.4% to 17.9% following harvesting. Punctual kriging
analysis was performed to prepare distribution maps of soil penetration resistance with 1 m intervals within the field. The
patterns of variation in soil penetration resistance following harvesting showed remarkable differences compared to preharvesting.
