Abstract For sowing grain crops on stubble, stubble seeders with tine coulters are used, which perform technological operations in one pass. However, they do not meet the requirements of agricultural machinery to ensure an even distribution seeds sub-spear space. The subsoil no-drill planting creates most favorable conditions for growth and development cultivated at same time, crop yields incre...

Maintaining winter stubble for the conservation of steppe passerines is widely implemented under the regional agrienvironmental program in Spanish dry lands. The adequacy of such measures was assessed in terms of bird density on different soil cover types in central Spain. Highest bird densities were found in ploughed, sown and fallow plots. Stubble plots were poorly used by wintering passerine...

Standards for the height of herbaceous vegetation remaining in meadows at the end of the growing season have been, and continue to be, implemented on public grazing lands throughout the Sierra Nevada. Although supporting research is limited, stubble height standards are intended to benefit riparian resources by limiting grazing pressure. This study illustrates how the timing and intensity of de...

Conservation practices that involve leaving mulch on the soil are known to increase fertility. However, is an important source of feed for ruminant livestock. Accordingly, trade-offs between mulching and stubble uptake by livestock currently hot topics in research field. In this study, a comparison quality stubbles wheat grown no-tillage conventional tillage fields rumen fermentation characteri...

Dynamics of cropland soil organic carbon (SOC) in response to different management practices and environmental conditions across North China Plain (NCP) were studied using a modeling approach. We identified the key variables driving SOC changes at a high spatial resolution (10 km × 10 km) and long time scale (90 years). The model used future climatic data from the FGOALS model based on four fut...

A field experiment was performed in Southwest Germany to examine the effects of long-term reduced tillage (2000–2012). Tillage treatments were deep moldboard plow: DP, 25 cm; double-layer plow; DLP, 15 + 10 cm, shallow moldboard plow: SP, 15 cm and chisel plow: CP, 15 cm, each of them with or without preceding stubble tillage. The mean yields of a typical eight-year crop rotation were 22% lower...

A series of 10 aircraft flights was conducted over agricultural fields to evaluate relationships between observed surface soil moisture and soft moisture predicted using passive microwave sensor observations. An a pr/or/ approach was used to predict values of surface soil moisture for three types of fields: tilled corn, no-till corn with soybean stubble, and idle fields with corn stubble. Accep...

In recent years, Fusarium head blight (FHB) outbreaks have occurred much more frequently in China. The reduction of burning of the preceding crop residues is suggested to contribute to more severe epidemics as it may increase the initial inoculum. In this study, a large number of Fusarium isolates was collected from blighted wheat spikes as well as from rice stubble with perithecia originating ...

This research focused on rill formation, rill density, and associated flow velocity distribution in rills at the field level and with different tillage treatments in the inland Pacific Northwest. The study was conducted by applying flow at three different rates under winter conditions, which provides the greatest potential for rill formation. The following tillage treatments were tested: chisel...

Fifty Merino weaner sheep grazing on a wheat stubble at Wongan Hills were fed ad lib. either oat grain mixed with limestone (2% w/w) or just oat grain during the summer and autumn of 1985. The addition of limestone to the oat supplement increased the growth of the sheep from 39 g/day to 83 g/day (P<O.OOl) during the first 70 days of feeding. A summer thunderstorm resulted in a brief germination...
