“…However, while CC gave the highest value, AC at various rates (except 30 kg N ha -1 which is a lower rate compared to that of NPK) gave higher values across the WOI compared with the control and NPK in both Alfisol and Ultisol. The high value of P obtained from compost treatments relative to NPK could be due to the ability of organic materials to reduce the P adsorption capacity of soils, and the potential of chemical fertilizers to reduce soil pH, thus increasing P fixation (von Wandruszka, 2006;Hepperly et al, 2009;Yu et al, 2013). This is in line with the findings of Ipinmoroti (2013) that compost released higher amount of available P than the control.…”

Article Info Received : 02.02.2017 Accepted : 22.05.2017 Acceleration of composting process could influence fertilizer-efficiency of the accelerated composts. This study therefore evaluated the nutrient release dynamics of different rates of a commercial accelerated compost (OBD-plus ) in two soils described as Alfisol and Ultisol, under laboratory incubation study, in order to generate information for simulation under field conditions. Accelerated compost (AC) at the rates of 30, 60, 90, 120, 150 kg N ha -1 , mineral fertilizer (NPK 15-15-15) and conventional compost (CC) at 60 kg N ha -1 , were each mixed with 2 mm sieved soil (Alfisol and Ultisol) in cups, and arranged in a completely randomised design with three replications. Soils without amendment served as control. The treated soils were retrieved at 2, 4, 6, 8, 10 and 12 weeks of incubation (WOI), air dried and analysed for pH, organic C, N, P and K, and data analysed using regression test. The results revealed that the 60 kg N ha -1 AC improved the pH, OC, N. P, K by -2%, 11%, 3%, 141% and 4% respectively, across the WOI, on the average of performance in the two soils, comparable with mineral fertilizer (-5%, 8%, -1%, 76%, 4% respectively) and CC (11%, 40%, 3%, 773%, 10% respectively). The 60 kg N ha -1 AC significantly correlated (p<0.05) with time of incubation only with respect to P (0.934) and gave a similar nutrient release pattern compared with mineral fertilizer and CC, in terms of C, N, P and K in both soils. It therefore showed that the accelerated compost evaluated could mineralize in a way similar to conventional compost and mineral fertilizers, despite its shorter composting duration to maturity.

“…For these authors, the slow and gradual release of nutrients throughout the growing season has been the main factor contributing to the increase in grain yield. This may be associated to an increased synchronization between the release of these nutrients and the plant needs (Muneshwar et al 2001, Nevens & Reheul 2003, enabling a gradual long-term improvement in soil physical, chemical and biological characteristics (Hepperly et al 2009). …”

With the intensification of pig farming systems, in Brazil, the production of swine waste has increased considerably, leading to water and soil contamination, due to its improper release. Pig slurry composting is an alternative that can be used in order to avoid or reduce negative impacts, especially for producers with physically limited farm areas, or those who intend to increase the number of animals in their production units. This study aimed at evaluating the influence of pig slurry compost doses on the agronomic characteristics and grain yield of proso millet. A randomized blocks design experiment was installed with four replications and five treatments: control without fertilization, control with mineral fertilizer (NPK) and pig slurry compost doses (4.0 Mg ha-1, 8.0 Mg ha-1; 12.0 Mg ha-1). The pig slurry composting increased the dry matter yield, number of grains per plant and grain yield of proso millet, when compared to the control with or without mineral fertilizer. The proso millet yield, at the doses of 8.0 Mg ha-1 and 12.0 Mg ha-1 of pig slurry, was superior than for both the control without fertilization and the control with the recommended mineral fertilizer, with the latter reaching a maximum agronomic efficiency at the dose of 8.0 Mg ha-1.

Fames and Microbial Activities Involved in the Suppression of Cassava Root Rot by Organic Matter

-The incorporation of organic matter has been used to manage of diseases caused by soilborne pathogen, but there is a gap in the use of coffee residues on disease supressiveness. The objective of this study was to evaluate the effect of organic matter sources against cassava root rot caused by F. solani CFF109. Fertilization with coffee residue (CR), cattle manure (CM), earthworm excrements (EE) and goat manure (GM) resulted in suppression of cassava root rot. The treatments of CR and CM presented higher reduction in the cassava disease severity. There were changes in the soil microbial community structure by organic matter incorporation, mainly in total fungi and Gram-negative bacteria populations. The total organic carbon and magnesium are negatively associated with disease severity. The microbial quotient, alkaline and acid phosphatase activities were positively and the biomarker a-15:0 was negatively associated with disease severity. This study indicated that agro-industrial residues can be recycled for providing organic matter and nutrients with effect for management of plant diseases by suppressing soilborne pathogens. This is the first evidence that the industrial residue of coffee can be use in the management of cassava root rot, caused by F. solani.Keywords: Manihot esculenta. Fusarium solani. Coffee residue.
