Aims: Availability of nutrients-rich topsoil for nursing cocoa seedlings is becoming limited and poor growth of cocoa seedlings in the nurseries has been ascribed to the use of unsuitable potting media. Experiments were conducted to investigate the suitability of compost in improving soil chemical properties and boost the growth of cocoa seedlings at the nursery. Study Design:  The experiment was laid out in a Completely Randomized Design (CRD) with four replications. Place and Duration of Study: The experiment was carried out at the main nursery of Cocoa Research Institute of Ghana, New Tafo-Akim, between September, 2014 and June 2015. Methodology: Polybags were filled with soil obtained from an old cocoa plot (K6O2) at Cocoa Research Institute of Ghana. The soil has been classified as Rhodic-Lixic Ferrasol. Three soil: compost mixtures treatments, that is, 90:10, 80:20 and 70:30% w/w were tested. A Standard foliar fertilizer and unamended soil were included as treated and untreated controls. Seedlings were raised from mixed hybrid cocoa and assessed at bi-monthly intervals for six months for growth. Pre and post treatments soil analyses were carried out using standard laboratory procedures. Results: Initial soil analyses showed that OC (1.18%), Ca (5.60 cmol kg-1), P (14.23 mg kg-1) and pH (5.63) were below the critical values required for good cocoa growth. The 70:30 soil: compost treatment produced significantly (P = .05) tallest plant (41.9 cm) with the unamended control the shortest (30.7 cm) at the end of the study. Residual pH (6.98), OC (2.30%), P (14.23 mg kg-1) and Ca (13.02 cmol kg-1) were significantly (P = .05) higher under the same treatment compared to the unamended control; pH (5.36), OC (1.04%), P (11.65 mg kg-1) and Ca (5.60 cmol kg-1). Conclusion: Less fertile soils could be improved with the addition of Municipal Solid Waste (MSW) compost for raising good quality cocoa seedlings at the nursery in Ghana.

Waste management is a vital environmental issue in the world today. Municipal solid wastes (MSWs) are discarded in huge quantities on a daily basis and need to be well controlled. Incineration is a common method for reducing the volume of these wastes, yet it produces ashes that require further assessment. Municipal solid waste incineration bottom ash (MSWI-BA) is the bulk byproduct of the incineration process and has the potential to be used in the construction sector. This paper offers a review of the use of MSWI-BA as aggregates in cementitious materials. With the growing demand of aggregates in cementitious materials, MSWI-BA is considered for use as a partial or full alternative. Although the physical and chemical properties of MSWI-BA are different than those of natural aggregates (NA) in terms of water absorption, density, and fineness, they can be treated by various methods to ensure suitable quality for construction purposes. These treatment methods are classified into thermal treatment, solidification and stabilization, and separation processes, where this review focuses on the techniques that reduce deficiencies limiting the use of MSWI-BA as aggregates in different ways. When replacing NA in cementitious materials, MSWI-BA causes a decrease in workability, density, and strength. Moreover, they cause an increase in water absorption, air porosity, and drying shrinkage. In general, the practicality of using MSWI-BA in cementitious materials is mainly influenced by its treatment method and the replacement level, and it is concluded that further research, especially on durability, is required before MSWI-BA can be efficiently used in the production of sustainable cementitious materials.

Municipal solid waste (MSW) may be a potential substitute for peat substrate in soilless medium. Adequate N and P are needed for a complete composting of MSW. MSW piles treated with diammonium phosphate (MSWP) or without P on Mar. 1994 were cured for 5 months. In Fall 1994, a factorial treatment combination of nine mixes and 3 fertigation treatments were evaluated in a completely randomized design on soft-pinched, single-stem `Red Sail' poinsettia. Mixes were MSW or MSWP ranging from 33% to 100% by volume in 1 peat: 1 perlite (v/v) and Sunshine mix was used as the control. Fertigation treatment began on the 1st, 2nd, or 3rd week after potting. Fertigation solution contained 266 mg·liter–1 N from 30N–4.4P–8.8K. The total fertigations ranged from eight to 10 for the 13-week study. With MSW mixes, shoot dry mass at the week 1 fertigation was 36% larger than at the week 3 fertigation. At the week 3 fertigation, shoot dry mass with 100% MSWP was ≈53% greater than with the 100% MSW. Shoot dry mass with 100% MSWP was similar to the control at the week 1 fertigation.

<p>The oil palm empty fruit bunches are solid waste produced from the processing of oil palms which have a large amount of potential to be used as compost and are expected to improve the physical, biological and chemical properties of the subsoil. This study aimed to evaluate the best combination between oil palm empty fruit bunches compost and rice husk charcoal on soil chemical properties in tomato. This research was conducted in Sona Village, Labuhanbatu Regency on December 2019-March 2020. Analysis of soil chemical properties was conducted at the Socfindo Seed Production and Laboratories (SSPL) Laboratory of PT. Socfin Indonesia. The study was conducted with a factorial randomized block design with 2 factors. The first factor was the application of oil palm empty bunches which consists of no oil palm empty bunches (control), 0.5 kg/polybag, 0.7 kg/polybag and 1 kg/polybag. The second factor was the application of rice husk charcoal which consists of non-husk charcoal (control), consisting of 0.2 kg/polybag and 0.4 kg/polybag. Data that had a significant effect after analysis of variance continued with DMRT at the level of α = 5%. The results showed that application of oil palm empty fruit bunches (0.7 kg/polybag) significantly increased pH and C-organic. Application of rice husk charcoal (0.2 kg/polybag) significantly increased C-organic and P-available.</p>

Technological and industrial advancements and the rapid increase in population, gradually changing the function of agricultural land into housing and industrial complexes. Overcoming the reduction of agricultural land, efforts made by farming vertically or verticulture methods.Shallots are an important vegetable commodity for the community, because of their high economic value and nutritional content. To reduce imports, it is necessary to increase production and quality of shallots through intensification and extensification. The purpose of the study was to determine the effect of the composition of the growing media, the effect of the dose of organic fertilizer in municipal waste, and its interaction with the productivity of shallots with verticulture cultivation techniques.The study was conducted in the experimental area of ​​the Faculty of Agriculture, UNTAG Banyuwangi, using Kooi's house, using a factorial completely randomized design (RAL) method with four replications consisting of two factors: the composition of the growing media and the dose of municipal waste fertilizer.Growth media composition factor (M) consists of 3 treatments, namely: M1 = soil: sand: husk (2: 1: 1); M2 = soil: sand: stem of fern (2: 1: 1); and M3 = soil: sand: cocopeat (2: 1: 1). The composition of municipal solid waste (P) consists of 3 treatments, namely: P1 = composition of municipal solid waste organic fertilizer 25%; P2 = composition of city organic waste 50%; and P3 = composition of urban organic waste 75%. Observation parameters in this study were Plant Height (cm), Number of Leaves, Wet Weight (grams), Number of Tubers, and Tuber Diameter (cm).
