“…It was concluded from these studies that during decomposition of organic residues, organic acids formed stable complexes with Fe and Al and/or were adsorbed by ligand exchange onto mineral surfaces, to consequently block P retention in the soil. Nevertheless, increased P retention due to organic residue application has also been observed (Jackman 1955;Harter 1969 For personal use only. (Table l).…”

Al and Fe contents, but some significant curvilinear relationships were observed.The results indicate that PP and PolyN-P may be retained to a lesser degree than OP in soils dominated by sesquioxides of Fe and Al. Application of farmyard manure (FYM) and alfalfa residues reduced the retention of ortho-and polyphosphate in the surface soils. The magnitude of the effect was greater with FYM than with alfalfa residues. The results suggest that P uptake from added polyphosphate could be enhanced by added organic residues. CaCO, effects were studied on Uplands topsoil and subsoil only. Added CaCO, reduced PP retention but had no effect on OP retention in Uplands topsoil. In the Uplands subsoil, added CaCO, consistently increased PP and PolyN-P retention but reduced OP retention. The samples were equilibrated under slow, continuous, end-over-end shaking for 24 h at 25"C. (197 l) and Mortvedt and Osborn (1977).

“…The relationships found by Williams, Scott, and McDonald (1958) and Jackman (1955) between extractable aluminium, phosphorus retention, and the contents of organic constituents are confirmed, and, in addition, there is an apparent inverse relationship between these variables and the index of the rate of organic matter mineralisation, K. The allophanic soils have the higher extractable aluminium, the higher organic matter content, and lower values for K.…”

Allophanic soils, compared with non-allophanic soils, are shown to contain more aluminium extractable by oxalate, more organic matter, and higher phosphorus retention capacities, but lower apparent specific rates of mineralisation. This difference in mineralisation rate is considered to be real, to be related to differences in the type of mineral colloid, and may determine the differing organic matter contents found in these soils.Annual rates of immobilisation of nitrogen, sulphur, and phosphorus in organic forms may be quantitatively important when compared with the amounts needed to maintain good pasture growth.Allophanic soils should be ploughed infrequently and shallowly in order to reduce subsequent immobilisation of available nutrients.The cropping of both allophanic and non-allophanic soils, appears to be equally possible provided that the organic matter content is at a near steady-state.

“…The behavior of the organic phosphate is to some extent analogous to that of the soil organic matter considered as a whole, and its amount is correlated with the contents of carbon and/or nitrogen (SCHOLLENBERGER [1920], PEARSON and SIMONSON [1939], KAlLA [1948KAlLA [ , 1963, THOMSON et al [1954], JACKMAN [1955b], WILLIAMS and DONALD [1957], ). However, it is a much more variable constituent than, for example, is organic sulfur, and wide variations have been reported in the ratios of carbon to organic phosphorus.…”
