Land application of sewage sludge: Phosphorus considerations

Keywords

Phosphorus, sewage sludge

Abstract

Phosphorus considerations are gaining increasing attention where sewage sludges are applied to land because of the continuing trend of rising P levels in sludges and the growing concern for environmental pollution and nutrient recycling issues. P in sludges has reached levels comparable to inorganic fertilizers in some cases while currently average values will be in the region of 2% P (dry solids basis). In reactions with soils the soluble component (or that capable of being solubilized) will be the most important fraction. Potential benefits to be gained from sludge applied P are large while hazards from disposal of sludge P are minimal owing to the transformations which P undergoes in soils. The finite world supply of resource P and the escalating costs of inorganic P fertilizers warrants that further research be directed towards making sludges more acceptable as a source of this nutrient. Unacceptable P pollution of the environment is an added stimulus to effectively dispose of and utilize such wastes simultaneously. S. Afr. J. Plant Soil 1984, 1: 21–29

    Evidence of a germination inhibitor in senescent soybean pod walls

    Keywords

    Field weathering, Germination, germination inhibitor, Glycine max (L.) Merr., soybean

    Abstract

    Water based pod extracts of the pod wall material of four soybean cultivars were found to reduce the germination rate of mustard (Sinapis alba L.) seeds. Highly significant differences were also observed in this respect between the different pod extracts. These results indicated the presence of a germination inhibitor in senescent soybean pod walls which might provide some protection against the effects of field weathering of soybean seeds.

      Perspectives on the Principles and Structure of the Soil Classification System in South Africa: Discussion and Practical Examples

      by Turner, David P

      The paper discusses revised principles, perspectives and structure for soil classification of natural soils in South Africa. An expanded ‘sphere of pedological interest’ is proposed through the formal recognition of a wider range of subsurface soil materials. The concept of soil groups has been recognised and is further developed as a formal classification category. In addition, a subgroup cate...

      Phytochemical Content, Antioxidant Capacity and Physicochemical Properties of Pomegranate Grown in Different Microclimates in South Africa

      by Mditshwa, Asanda, Fawole, Olaniyi A, Al-Said, Fahad, Al-Yahyai, Rashid and Opara, Umezuruike L

      We investigated the antioxidant and physicochemical properties of pomegranate (Punica granatum cv. Bhagwa) fruit grown in three microclimates in South Africa. The physicochemical properties of fruit peel and arils differed among the growing locations, including weight and redness color of both peel and arils. Contents of vitamin C, anthocyanin and total phenolics were 0.67–1.41 mg ml−1, 0.07–0....

      Estimation of Thrips (fulmekiola Serrata Kobus) Density in Sugarcane Using Leaf-Level Hyperspectral Data

      by Abdel-Rahman, Elfatih M, Way, Mike, Ahmed, Fethi, Ismail, Riyad and Adam, Elhadi

      The aim of this study was to investigate the potential use of leaf-level hyperspectral data to predict the density of sugarcane thrips Fulmekiola serrata (Kobus). A hand-held spectroradiometer was used to make the spectral measurements on spindle leaves of 4- to 5-month-old plants of sugarcane cv. N19 growing in commercial fields near Umfolozi, South Africa. A random forest algorithm followed b...

      A Revised Perspective on Principles of Soil Classification in South Africa

      by Turner, David P

      Limited significance has been given to the formal recognition of certain subsoil materials in the South African Soil Classification System. Three principles in the current classification system are discussed using variants of soil profiles associated with the Avalon soil form. The retention of the arbitrary depth criterion is questioned in favour of the recognition of an enlarged ‘sphere of ped...
