The proportion of phosphorus (P) that is in organic form is greater in solid than in liquid manure. P in liquid manure can occur as particulate P such as trimagnesium Transport ofNitrogen, Phosphorus and Microorganisms 33 phosphate (Fordham and Schwertmann 1977), or as soluble components such as orthophosphates and low molecular weight organic phosphorus compounds. Leinweber (1997) found that the total P in dry poultry manure was less than in liquid swine man ure but the proportion ofsoluble Pwas greaterin poultrymanure.
1992; Jimenez and Stegeman 1990), heat shock (HSP70 stress proteins) (Pyza et al. 1997; Bradley 1993), antioxidant enzymes (DiGiulio 1992; Doyotte et al. 1997), and various measures ofDNA damage (Shugart et al. 1992; Theodorakis et al. 1992). In many cases, these biomolecular and biochemical measures have proven to be excellent biomarkers of exposure to a variety of environmental stressors. These exposure biomarkers cannot serve, however, as ecologically relevan t indicators of stress effects at higher levels ofbiological organization.
The future development of specific DNA probes for other soil organisms is in progress. The successful application of these probes will require continued co operative and multidisciplinary research, to enable the quantification of the organism to be related to its effect in soil or on plants. The regulatory and registration frameworks that apply to the release and commercial use ofboth native and genetically manipulated microbial pesticides are complex, time-consuming and can be costly. The testing and commercial registration of the genetically modified Agrobacterium strain K1026 for biocontrol of crown gall disease is one example.
