Efeito da adubação orgânica sobre as frações de carbono de solos cultivados com alfacen americana Organic fertilizer effects upon carbon fractions from soils cultivated with iceberg lettuce

Avaliou-se, neste estudo, o efeito da aplicação de adubos orgânicos, minerais e calagem, nas frações húmica, fúlvica e nos teores de carbono orgânico de um Latossolo Vermelho e de um Cambissolo, cultivados com alface (americana). O experimento, realizado no Departamento de Ciência do Solo da Universidade Federal de Lavras, foi constituído de cinco doses de material húmico (0, 20, 40, 100 e 200 L ha-1), três tipos de adubação (composto orgânico, esterco de aves e mineral) e calagem (com e sem uso de calcário), em cinco repetições. No Cambissolo, a calagem contribuiu para a diminuição do teor de C orgânico nas áreas adubadas com fertilizante mineral e composto, e aumentou o armazenamento de C no solo adubado com esterco de aves. Em relação à adubação mineral, o uso de adubo orgânico aumentou os teores de C-fração ácido húmico e a relação C-húmico/fúlvico. No Latossolo, independente do tipo de adubação, o uso da calagem propiciou o armazenamento no solo de mais C do que o observado na área sem correção da acidez. Os efeitos da calagem e das fontes de nutrientes variaram em função da fração orgânica analisada ou das relações entre seus teores de carbono.<br>This study evaluated the effects of organic and mineral fertilizers and liming, on humic, fulvic, and organic carbon fractions of an Inceptisol and an Oxisol grown with lettuce. The experiment was carried out at the Soil Science Department of Federal University of Lavras, Minas Gerais state, Brazil. It was performed with 5 levels of soil conditioner (0, 20, 40, 100, 200 L ha-1), 3 fertilizers (organic compost, chicken manure and mineral), and liming (present or absent) using five replications. In the Inceptisol essay, the liming contributed to a decrease in the organic-C content in the mineral and compost fertilized plots, and increased C-accumulation in the treatments under chicken manure. The organic fertilizer increased the content of C-humic acid and the relation Chumic/fulvic. In the Oxisol essay, the liming contributed to C-accumulation when related to the treatments without liming. Liming effects and fertilizers varied as a function of the analyzed organic fractions and C content

A Review of the World’s Soil Museums and Exhibitions

The soil science community needs to communicate about soils and the use of soil information to various audiences, especially to the general public and public authorities. In this global review article, we synthesis information pertaining to museums solely dedicated to soils or which contain a permanent exhibition on soils. We identified 38 soil museums specifically dedicated to soils, 34 permanent soil exhibitions, and 32 collections about soils that are accessible by appointment. We evaluate the growth of the number of museums since the early 1900s, their geographical distribution, their contents, and their attendance. The number of museums has been continuously growing since the early 1900s. A noticeable increase was observed from 2015 to 2019. Europe (in a geographical sense), Eastern and South-East Asia have the highest concentration of soil museums and permanent exhibitions related to soils. Most of the museums’ attendance ranged from 1000 to 10,000 visitors per year. Russia has the largest number of soil monoliths exhibited across the world’s museums, whereas the ISRIC-World Soil Museum has the richest and the most diverse collection of soil monoliths. Museums, collections, and exhibitions of soil play an important role in educating the population about this finite natural resource that maintains life on the planet, and for this reason, they must be increasingly supported, extended, and protecte
