Abstract:

Fertilizer P fixation and fertilizer N losses in soils may be reduced through additions of polyphenolic compounds. The influence of ammonium lignosulfonate (NH$ sb4 sp+$-LS) on triple superphosphate (TSP) efficiency was investigated in a soil incubation study using three Quebec soils and in a growth bench study using one soil. For the incubation study, soils were analyzed for pH and P extractability, as a function of NH$ sb4 sp+$-LS rate and time. In the growth bench study, TSP and NH$ sb4 sp+$-LS were applied at varying rates and corn (Zea mays L.) dry matter yields and nutrient compositions

Abstract:

The sugar refinery process used by Lantic Sugar Ltd generates three by-products having characteristics that give them potential as soil amendments or fertilizers, particularly as a phosphorous and calcium source. Laboratory and a field trials were conducted in order to examine the changes in agronomic properties of soil produced by the application of these residues.<br>During the laboratory experiment, the by-products examined were spend bone char (SBC), filter-press mud (FPM), clarification scum (SCU) and a compost (COM) produced using FPM and SCU, where as in a field experiment, COM, SBC and

Abstract:

Variable rate prescription maps can improve nitrogen use efficiency within a field by directing N applications where it is needed. If NDVI collected with a drone could be used to predict yield, it also could be used to develop N rate prescription maps. Experiments on wheat were carried out in farmer fields and in small plots. Small plot experiments consisted of six rates of nitrogen and NDVI was collected from sensors on a drone and was correlated to yield and protein after harvest. NDVI measurements were also collected from farmer fields that had a nitrogen rich strip applied to the field al

Abstract:

Phosphorus in wastewater is mainly present as inorganic phosphate forms and is commonly removed through chemical co-precipitation using Al(III) and Fe(III) salts. However, precipitation is expensive and generates a waste to be disposed. If the recovery of phosphorus is the target objective the solution could be based on the integration of specific chemical processes or physico-chemical treatment process to recover phosphorous as pure mineral phases or supported onto low-cost inorganic sorbents. Recovery of phosphate from diluted streams has been evaluated by integration of a pre-concentration

Allerdings sind die agroökologischen Wirkungen noch nicht hinreichend erforscht.

This low level of ash utilisation in Australia is inevitable due to the combination of inherently high transport costs, and relatively low value products. This situation argues for more value-added utilisation of c

Abstract:

Composting is a sustainable method to deal with huge amount of daily organic waste due to its robustness and easy operation. However, food waste (FW) as the main material in composting has disadvantages such as the heterogenous properties, high foreign matters contamination, high moisture content, low C/N ratio, poor structure, low porosity and high acidity during the initial phase of composting. These shortcomings not only influence degradation efficiency but also cease the composting process. Therefore, a bulking agent is required to increase the porosity and adjust the moisture content as w

Microbial fertilizers are newly developed agricultural materials which have been proved to promote crop growth. Besides, the application of microbial fertilizer also shows potential in partly replacement of chemical fertilizer. Under the efforts of industry, government, academic organization, and research institut

Abstract:

Sustainability in natural ecosystems is dependent on chemical and biological balance in the soil which is mainly governed by the cross-interaction of microbial communities with organic matter and plant roots. The development of efficient tools to manage these key factors could offer to modern agriculture a way to improve productivity and reduce the reliance on chemical fertilizers. The research described in this thesis is focused on the increase of efficiency of the most promising bio-effectors (i.e. plant growth promoting microorganisms PGPMs) and active natural compounds derived from recycle

Thesis (MScFor)--Stellenbosch University, 2014.<br>ENGLISH ABSTRACT: A field trial of six replications was established to test the effect of various wood ash and fertilisers application rates on soil chemistry, tree nutrition and early growth rate of a clonal Eucalyptus grandis x urophylla stand. Wood ash from pulpmills is currently disposed of in landfills. Increasing costs and potential environmental risks have driven companies to investigate alternative disposal methods. Ash consists of a combination of carbonates, hydroxides and other calcium containing minerals that induce the liming effe

Based upon the idea of “What comes from nature, goes back to nature”, kitchen and food wastes could be reused by transformed to organic liquid fertilizers. The reuse of the wastes is environmental friendly. The aim of this work is to investigate the effects of different liquid fertilizers and chemical fertilizers on the growth of Pak Choi, a chinese vegetable. Two typ

Abstract:

A strategy for beneficiation of wastewater streams from fissure and process water developed for a gold mine operation in the west of Johannesburg was tested for viability in a pilot study. The investigation was aimed at evaluating the compliance of the finally discharged effluent streams with the current Water Use Licence (WUL). The core of the water recovery process consisted of softening to remove divalent cationic species, followed by ion exchange processes employing Strong Acid Cationic (SAC) resins and Weak Acid Cationic (WAC) resins. An operational design limitation was that the crystala

However, several factors resulted in a consumption of n-6 PUFAs approximately 20 times greater than the consumption of n-3 PUFAs, showing a lack of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in the dietary requirements. Both come from marine fish, such as salmon and mackerel, or from fish oils. As result of the increasing demand for food
