ABSTRACTThe use of rock dust in agriculture has increased worldwide and particularly Brazil since its regulation by Law 12.890 (2013). However, some inconsistent results standard chemical analysis soils amended with have drawn attention, among them, cation exchange capacity (CEC). This paper evaluates the increase sum bases (SB) CEC two commercial (magnesium silicate), measured four methods: ion resin, potassium chloride (KCl), compulsive cesium adsorption. The maximum possible SB soil was...
Objetivou-se, com este trabalho, avaliar a influência da salinidade no crescimento de espécies leguminosas comumente utilizadas como adubação verde. Conduziu-se um experimento em ambiente protegido, ano 2010, blocos ao acaso, esquema fatorial 5 x 2. Os tratamentos foram cinco níveis sais (0,8, 1,6, 2,4, 3,2 e 4,0 dS m-1 25 ºC) duas leguminosas: Crotalaria juncea spectabilis. A água irrigação foi preparada adição NaCl as irrigações feitas manualmente, dias alternados, base consumo das plantas...
An integrated knowledge of the soil and its deeper substratum is required when dealing with environmental issues Critical Zone research. Though lower boundary for classifying soils set at 200 cm in both Soil Taxonomy (ST) World Reference Base (WRB), these systems are ill equipped categorising layers below diagnostic horizons. The authors reflect on need solum–subsolum continuum based data four profiles from Brazil. solum was classified ST, WRB Brazilian Classification, subsolum...
Este trabalho objetivou avaliar o desenvolvimento da cebolinha verde em detrimento a lâmina de irrigação e adubação sintética. O experimento foi conduzido na área experimental do Campus Arapiraca UFAL. delineamento teve fatorial 5 x 6, DBC, com quatro blocos, os tratamentos adotados foram cinco lâminas seis níveis NPK. Os dados obtidos submetidos à análise variância, regressão multivariada: componentes principais (ACP) hierárquica Clusters (AHC), utilizando software estatístico R. resultados...
Saprolite plays a central role into hydrologic and nutrient cycles. Despite that, saprolite research is scattered uses heterogeneous, sometimes conflicting, methods concepts. During field work, it difficult to assign the boundary between soil saprolite. This paper aimed identify subjacent logic that pedologists use regolith volume its or nature. To achieve this goal, tree algorithm was used build hierarchy of physical chemical properties set profiles. Such hierarchization expose inner,...
