Sandy soil often has low organic matter (SOM) content, cation exchange capacity (CEC), and water storage levels. requires specific management techniques to improve quality. The purpose of this study was evaluate chemical characteristics microbial activity sandy soil, as well the effects different rotation systems on crop yield in these environments. treatments consisted cultivation with cover c...

and Reule, 1994; Norwood, 2000; Peterson et al., 1993; Schlegel et al., 2002). No-till (NT) production systems, especially winter wheat (Triticum Dhuyvetter et al. (1996) reported that the more intenaestivum L.)–summer crop–fallow, have increased in the central Great sive cropping systems had higher profit potential than Plains, but few N fertility studies have been conducted with these systems...

The objective of this paper is to report the cumulative effects of cropping system intensification on the near surface soil physical properties (surface one inch of soil) within the Colorado dryland agroecoystem project, which has been in existence since 1986. Intensifying cropping systems from wheat-fallow to wheat-com-fallow to continuous cropping, increased crop residue return to the soil. R...

Soil amendments can improve the sustainability of agricultural systems by building soil carbon and improving numerous other soil health indicators, including soil structure, water infiltration and retention, bulk density, nutrient availability, and microbial activity. This chapter covers some general considerations relevant to the use of soil amendments followed by a discussion of biosolids, an...

Long-term use of conventional tillage and wheat (Triticum aestivum L.)-fallow systems in the northern Great Plains have resulted in low soil organic carbon (SOC) levels. We examined the effects of two tillage practices [conventional till (CT) and no-till (NT)], five crop rotations [continuous spring wheat (CW), spring wheat-fallow (W-F), spring wheat-lentil (Lens culinaris Medic.) (W-L), spring...

I describe the design of NooShare, a decentralised ledger similar to Bitcoin [11] with the novel feature that its proofs of work are iterations of essentially arbitrary Markov-Chain Monte-Carlo (MCMC) chains, the scheduling of which can be purchased using the currency itself. It is a novel economic basis for sharing fallow computational resources.

Replacing portions of fallow between sorghum [Sorghum bicolor (L.) Moench] harvest and wheat (Triticum aestivum) planting with cover crops provides opportunity to increase productivity profitability in dryland winter wheat–sorghum–fallow (WSF) cropping systems. The objective this study was identify potential spring replacement management optimize resource use efficiency a WSF system. conducted ...

Doñana National Park (DNP) in southern Spain is a UNESCO Biosphere Reserve where commercial hunting and wildlife artificial feeding do not take place and traditional cattle husbandry still exists. Herein, we hypothesized that Mycobacterium bovis infection prevalence in wild ungulates will depend on host ecology and that variation in prevalence will reflect variation in the interaction between h...
