Manure characteristics can influence the potential for P transfer in runoff following land application of manures. This research assessed the influence of manure characteristics on P solubility in calcareous soils using manures from poultry (Gallus Domisticus) fed a variety of grain-based diets with the manures containing a range of total P (5.6–16.4 g P kg), water-extractable P (WEP, 0.9–4.7 g...

The effect and relative contributions of C P inputs on soil microbial biomass (MBP) accumulation were studied in three long-term fertility experiments with various climate characteristics at Qiyang, Yangling, Wulumuqi. maximum MBP all sites was 47.8 mg kg-1. accumulated per unit (mg kg-1 soil) correlated a 4.91 increase Olsen P. For each surplus (kg ha-1), manure stubble increased by 330, 3.7, ...

In this paper, we present a theory for bounding the minimum eigenvalues, maximum eigenvalues, and condition numbers of stiffness matrices arising from the p-version of finite element analysis. Bounds are derived for the eigenvalues and the condition numbers, which are valid for stiffness matrices based on a set of general basis functions that can be used in the p-version. For a set of hierarchi...

We describe a theoretical investigation into the semantic space described by our interlingua (IL), which currently has 191 main verb classes divided into 434 subclasses, represented by 237 distinct Lexical Conceptual Structures (LCSs). Using the model of aspect in Olsen (1994; 1997)—monotonic aspectual composition—we have identified 71 aspectually basic subclasses that are associated with one o...

the overgrazing and excessive utilization of rangelands has caused vegetationand soil degradation in many rangelands. in the rangeland management, the soil andvegetation elements, environmental factors and livestock should be considered as decisionmaking agents. various methods are applicable for the rangeland restoration as contourfurrows and mortar stone dam. in order to evaluate the effects ...
