Purpose In soil-based nursery media, topsoil, poultry droppings and sawdust conventionally provide anchorage, nutrients and aeration, respectively. Considering poultry droppings’ scarcity and sawdust’s inertness nutrient-wise, more readily available organic wastes should be explored as substitutes. Here, we evaluated the effect of such substitution on media fertility, aimed at seeking alternatives to the conventional practice. Methods […]
Purpose Vinasse is produced in large quantities as a by-product from bioethanol production. To ensure environmental sustainability, a beneficial use was sought. Previous study showed that short-term crops grown with vinasse-amended soil provided higher yield than crops treated with chemical NPK (15:15:15) fertilizer. To understand this phenomenon, this study sought to establish the nutrient release […]
Purpose Soil fertility management requires a precise assessment of nutrient release from organic amendments to decide the rates and frequency of application. Method Time-dependent release of some macro- and micro-nutrients from farmyard manure, mushroom compost, poultry manure, vermi-compost, biogas slurry and biochar of Lantana sp. was studied during 120 days incubation through entrapment of released nutrients on ion […]
