Adsorptive Equilibrium

Soil has many functions in sustaining life. The prerequisite conditions for proper soil functioning may be expessed in terms of quality. Chemical quality of soil is predominantly determined by behaviour of compounds in soil. Compound behaviour is the result of the interactions of properties of the compounds and of the soil system under consideration. These can satisfactorily be described by applying methodical rules as derived in soil chemistry and soil physics. This is elaborated with examples referring to the static situation prevailing at adsorptive equilibrium, and to the dynamic situation of compound displacement in soil. The variability of soil properties appears to be of major concern. In these examples, attention is limited to the behaviour of cadmium in soil.

Mineralization Of Organic Matter

In recent decades, various procedures have been introduced to improve the conditions of the cultural ponds' conditions in aquaculture. Numerous biological products, including live bacterial inocula, preparation of enzymes, extracts of plant products, and many others, are being promoted to induce water and soil quality conditioners in aquaculture ponds. However, several studies have shown no significant effect of bacterial inoculums, and also the treatment with enzymatic preparation led to an enhancement of microbial mineralization of organic matter, but no effective net production of fish was observed. Probiotics have recently been applied to aquaculture. Probiotics are the live cells or a substrate that induce its benefits by stimulating growth, digestion, and active immune response. Probiotics can also improve water and soil quality. The current study summarizes the role of commercial probiotic ‘Super-PS’ on water quality and soil quality maintenance during the culture of freshwater fish Pangasius hypophthalmus fingerlings.

Orchard Soils

Soils and crops in orchard agrosystems are particularly vulnerable to climate change and environmental stresses. In many orchard soils, soil biodiversity and the ecosystem services it provides are under threat from a range of natural and manmade drivers. In this scenario, sustainable soil use aimed at increasing soil organic matter (SOM) and SOM-related benefits, in terms of soil quality and fertility, plays a crucial role. The role of soil macrofaunal organisms as colonizers, comminutors and engineers within soils, together with their interactions with microorganisms, can contribute to the long-term sustainability of orchard soils. Indeed, the continuous physical and chemical action of soil fauna significantly affects SOM levels. This review paper is focused on the most advanced and updated research on this argument. The analysis of the literature highlighted that a significant part of soil quality and fertility in sustainably-managed fruit orchard agrosystems is due to the action of soil macrofauna, together with its interaction with decomposing microorganisms. From the general analysis of the data obtained, it emerged that the role of soil macrofauna in orchards agrosystems should be seriously taken into account in land management strategies, focusing not exclusively on fruit yield and quality, but also on soil fertility restoration.

Sheep Production

For five years, three rates of ammonium sulphate (N0, N1, and N3: 0, 280, and 840 kg/ha/year) were applied as a split dressing to ,a pasture of Bromus mollis L. and Trifolium subterraneum L. which was continuously grazed by wethers set-stocked at 8.6 and 12.4 sheep/ha. The N0 treatment produced clover dominance, N1 a mixed sward, and N3 grass dominance. The higher stocking rate increased the proportion of clover in the mixed sward. These differences in botanical composition produced three significant effects on the relation between liveweight gain and quantity of green pasture on offer. An increase in the proportion of clover in the sward increased: (1) the quantity of herbage dry matter on offer required for liveweight maintenance; (2) the maximum rate of liveweight gain; (3) the quantity of dry matter on offer at the point of 90% maximum liveweight gain. Regressions of those three parameters on botanical composition accounted for over 90% of the variance. The effects of treatments on liveweight at other times of the year are also described. In the first year of grazing ammonium sulphate increased liveweight, apparently because of increased pasture on offer after emergence. In subsequent years the effect of ammonium sulphate was reversed: liveweight was reduced, and this was associated with lower nitrogen concentrations in, and lower quantities of, herbage produced. Wool elongation rates were greatest in spring and lowest prior to the germinating rains in autumn. Elongation rate was unaffected by stocking rate and only slightly affected by ammonium sulphate. From January to April, greatest elongation occurred on the grass-dominant N3 paddocks; from May to December greatest elongation occurred on the clover-dominant N0 paddocks. The implications of the role of nitrogen fertilizer in relation to sheep production in the winter rainfall regions of Australia are discussed.
