“…In our experiment, improved yields were obtained when using organic manure as compared with local fertilization. It has already been shown that phosphorus availability in andosols was improved with organic manure [20]. It is also known that the organic phosphorus fraction (75% of total P) from poultry manure strongly integrates the pool of the soil steady organic matter [21] and organic colloids prevent soluble phosphates from linking with soluble Fe and Al in acidic soils.…”

--Introduction. Little is known about the impact of organic manure on andosol. Materials and methods. Two varieties of Solanum lycopersicum L. (cvs. 'Rio grande' and 'Rossol VFN') were grown under tropical andosol. The soil was silty, acidic and very poor in Bray P (3 mg·kg -1 ) with a strong imbalance in the (Ca:Mg:K) ratio of (74.0:25.0:0.7). Five fertilization treatments were used: (i) control with no fertilizer, (ii) minerals, with a (Ca:Mg:K) ratio of (76:18:6) and 75 mg P·kg -1 of soil; (iii) poultry manure with a (Ca:Mg:K) ratio of (68:24:7) and 450 mg P·kg -1 of soil; (iv) a combination of (ii) and (iii), and (v) mineral fertilization as applied by local farmers, with a (Ca:Mg:K) ratio of (73:25:1) and 54 mg P·kg -1 of soil. Results. All cationbalanced treatments (organic, mineral or a combination of both) significantly improved plant growth, the number of trusses and fruits per plant, the marketable fruit yield and fruit P, K, Ca and Na contents of both tomato varieties considered. The 'Rio grande' variety was the most productive (32-44 t·ha -1 ) compared with the 'Rossol' variety (20-22 t·ha -1 ). There was no major difference between the organic fertilizer and the cation-balanced mineral fertilizer. There was no effect of mineral fertilizer with an unbalanced cation composition on tomato plant growth and production as compared with unfertilized control. Conclusion. In tropical andosol poor in potassium and phosphorous and with excess of Mg, application of poultry manure in adequate dosage and at the right time is capable of sustaining tomato fruit production, as well as the application of calculated inorganic fertilizer. ). Il n'y a pas eu de différences majeures entre les plants fertilisés avec l'engrais organique et ceux ayant reçu un engrais minéral équilibré en cations. La fertilisation minérale déséquilibrée en cations n'a pas eu d'effet sur la croissance et la production des plants de tomate par rapport au traitement témoin sans engrais. Conclusion. Dans les andosols tropicaux pauvres en potassium et en phosphore et présentant un excès de magnésium, l'application de fumier de volaille à des doses adaptées et au bon moment permet de maintenir une production de tomates équivalente à celle obtenue avec un engrais minéral bien dosé.Cameroun / Solanum lycopersicum / fruits / andosol / fertilisation / engrais minéral / engrais organique / croissance / qualité

“…Further, high amounts of organic P are produced, presumably during the decomposition of enriched compost process as well as in the soil in comparison of ordinary compost process, and this increases P uptake by the plants (Biswas and Narayanasamy 2002). Odongo et al (2007) reported that P-enriched composting in the presence of wheat straw significantly increased P availability and increased plant growth. Higher nutrient uptake by potato and soybean due to enriched composts could possibly be attributed partly to the contribution of other plant nutrients and partly to a favourable effect on physical, chemical and biological properties of the soil which in turn, helps in higher biomass production as well as greater nutrient uptake by plant.…”

This manuscript focuses on the nutrient recycling potential of enriched compost prepared using rice straw, low-grade rock phosphate (RP) and waste mica along with Aspergillus awamori and their effect on crop productivity and changes in soil fertility under potato-soybean cropping sequence in an Inceptisol of Indo-Gangetic Plains of India. Enriched composts had higher total as well as bioavailable P and K content than ordinary compost. Data emanated from the field study revealed that yield and uptake of N, P and K by potato tubers were significantly increased due to application of inorganic fertilizer and enriched compost over control. Application of 50% recommended dose of NPK fertilizers (RDF) along with 4.0 Mg ha -1 of enriched compost product-C prepared by rice straw ? RP @ 4% P ? waste mica 4% K ? Aspergillus awamori resulted in 43.3% additional yield and 102.3, 67.0 and 62.2% additional N, P and K uptake by potato over control, respectively. Significant increase in yield and uptake of N, P and K by soybean grown on residual fertility were also observed over control. Post-harvest soil analysis indicated a significant build-up in soil organic C, available N, P and K due to application of enriched compost in combination with inorganic fertilizer over 100% RDF. The results clearly showed that enriched compost could be an alternative and cost effective option to prepare a value added product using agricultural wastes and low-grade minerals like RP and waste mica in place of costly chemical fertilizer for crop production and maintaining soil fertility.

“…Rock phosphate enriched compost produced longer stem, larger shoot diameter, and leaf area and biomass than rock phosphate amended substrates. This is probably due to the fact that rock phosphate underwent the composting process enriches the final compost available P (Goyal & Mishra 1983;Singh et al 1983;Akande et al 2005;Odongo et al 2007;Nishanth & Biswas 2008;Biswas et al 2009). During composting, OM decomposition produces organic acids and evolves CO 2 forming weak carbonic acid which enhances the dissolution of RP and increases P solubility (Biswas & Narayanasamy 2006).…”

“…Global peak of P production is predicted to occur around 2030 (Cordell et al 2009;Ashley et al 2011). Although there are technical and scientific challenges in the search for alternatives to rock phosphate, there are ways to increase the efficiency of P: for instance recovering P from waste treatments (Güney et al 2008;Cordell et al 2011), use of genotypes that mobilize the soil P (Föhse et al 1988;Horst et al 2001;Bucher 2007) or increasing solubility of the low-reactive rock phosphate by composting (Biswas & Narayanasamy 2006;Odongo et al 2007;Aria et al 2010). The search for practicable alternatives to peat-based growing media has led many researchers to substitute peat with other organic components.…”

b Consiglio per la ricerca e la sperimentazione in agricoltura -Centro per lo studio delle relazioni tra pianta e suolo -Agricultural Research Council, Research Centre of soil-plant system (CRA-RPS),Peat substitution in growth media with renewable organic components such as compost is one of the main challenges for organic nursery production. Two greenhouse experiments were carried out to investigate the performance of tomato seedlings grown on different compost-based growing media. The factors investigated were: (1) dose of compost, (2) level of phosphorus (P) enrichment and, only in the experiment 2, (3) source of P enrichment (rock phosphate enriched compost or rock phosphate amended growing media). Tomato seedling length, diameter, leaf area, leaf dry weight, shoot dry weight and seedling N, P and K concentrations were determined. Growth substrates with 30% compost showed the best seedling growth regardless of the source and level of P enrichment. Furthermore, at higher compost doses (60%) in the growth media, rock phosphate enriched compost (0.59 g P kg 21 compost) produced seedlings that were comparable to the rock phosphate amended substrates (1.18 g P kg 21 substrate). This demonstrates the capacity of the rock phosphate enriched compost in the growing media to supply more P to seedlings than the rock phosphate amended substrate. Moreover, growth media with 60% compost and peat-based growing media with standard rock phosphate application produced similar seedling growth confirming the potential of compost to substitute 60% of the peat in the growth media.
