This study aimed to evaluate enzyme activity, glomalin-related soil proteins (GRSP), chemical attributes, and total organic carbon (TOC) in two Agroforestry systems (AFS) (AFS-1 AFS-2), a traditional agriculture area (TA), secondary forest (SF) Paraty (RJ). Soil samples (from 0 5 cm depth) were collected during the rainy dry seasons. AFS improves and/or maintains indicators based on pH increase, reduces aluminum saturation nutrient content (Ca, Mg K), when compared with SF. The contribution...
Monitoring the spatial variability of soil attributes is an important tool in crop management. Multivariate statistical methods and geostatistics were jointly applied to evaluate influence different on soil. The aim this research was apply multivariate principal component analysis map area subjected conservation management identify most relevant physical chemical attributes. Disturbed undisturbed samples collected georeferenced at 99 points study depths 0.00 - 0.10 m 0.20 measure soil; (PC)...
Soil is a fundamental natural resource for subsistence and development of humanity, exploited mainly agriculture. Agricultural practices, though, are improperly performed, compromising edaphic conditions favoring erosive processes, which culminate in the loss soil nutrients. Water erosion represents main form degradation, given that impact raindrops on results detachment particles, process favored by factors such as climate, relief, vegetation use occupation. The objective study was to...
ABSTRACT Studies on spatial variability of soil attributes tropical pastures gather information that can assist in decision making about managements these soils. The objective the present study was to evaluate chemical and their effects grass yield Tifton 85. experiment carried out an area 3.91 ha at Feno Rio Farm Federal Rural University de Janeiro, Seropédica, RJ, Brazil. Soils 0-0.20 0.20-0.40 m layers were sampled considering irregular sampling mesh, a total 50 georeferenced points....
The use of Precision Agriculture tools and soil attributes has contributed to local agricultural management in the identification different productive potentials quality pastures. present study aimed investigate spatial variability organic matter fractions chemical physical delineate zones pasture soils cultivated under tropical conditions. was conducted on a hay production farm located Seropédica, Brazil. Fifty points were collected irregular grid samples taken at depths 0-0.20 0.20-0.40 m...
A erosão promove danos às lavouras, solo, assoreamento e poluição das bacias hidrográficas. Desse modo, objetivou-se avaliar a perda de nutrientes solo em diferentes estágios evolutivos voçorocas na bacia hidrográfica do Ribeirão Cachimbal, Pinheiral - RJ. As foram classificadas morfologicamente inicial, juvenil, madura senil. Foram coletadas amostras deformadas indeformadas profundidade 0,00-0,10 m face interna cada voçoroca. Procedeu-se análises para avaliação da fertilidade, carbono...

O desenvolvimento e a expansão industrial desenfreados propiciaram o uso inadequado do solo das águas subterrâneas. Entretanto, conhecimento da vulnerabilidade áreas onde ocorre exploração é de extrema importância para gestão sustentável destes recursos, bem como ocupação solo. presente trabalho apresenta avaliação sistema aquíferos município Queimados (RJ). A área experimental fica localizada no Distrito Industrial deste município, foram cadastrados trinta três pontos coletas. Para foi...
A proposta deste artigo com caráter ensaístico é ser uma auto etnografia, reconstrução das reminiscências da minha "infância viada" como meio de compreender o controle escolar sobre a (homos)sexualidade. Objetivo neste texto, dessa forma, apresentar em um primeiro momento panorama histórico normatização sexualidade infantil e escola espaço mesmas no Brasil, seguida fazer crítica, partir experiência pessoal quando criança, forças que atuam forma excludente, colonizadora subalternizante nos colégios.
Water erosion acts as the main form of soil degradation, promoting release particles that associated with factors such climate, relief, vegetation and use occupation favor this process. This study aimed to evaluate whether gullies are more likely be present in a specific type landform how physical chemical characteristics vary between internal external environments concave convex gullies. The was performed Cachimbal River sub-basin, Pinheiral (RJ). Gullies were mapped quantitative...
