1. Biochar and swine wastewater: Effects on soil fertility of different textures and corn nutrition
ABSTRACT The use of organic waste in agriculture has stimulated the search for technologies that reduce environmental pollution. Among the residues are the biochar and swine wastewater (SW), which incorrectly disposed cause negative impacts, however, when combined, they can enhance agricultural production, due to the synergism between both. In this sense, th

2. SOIL CHEMICAL CHANGES AND RESEMBLANCES IN A CHRONOSEQUENCE RAINFOREST-SUGARCANE-PASTURELAND IN THE ATLANTIC FOREST BIOME
ABSTRACT This study evaluated soil chemical and isotopic changes in soils of a chronosequence rainforest-sugarcane-pasture in the Atlantic Forest biome, Brazil. Soil samples were collected (0-20 cm) in areas of native Brazilian Atlantic rainforest, sugarcane plantation and pastures of Brachiaria decumbens. The soil analyses performed were: pH (water 1:2.5),

3. Achados de fundoscopia de pacientes diabéticos e/ou hipertensos
ABSTRACT Soil compaction in agricultural areas has greatly increased in recent decades due to intensive farming practices, including short-cycle crops and machinery intensification. This study aimed to evaluate the impacts of management systems on the physical quality of a dystrophic Yellow Oxisol, in the Cerrado region of Brazil. Treatments consisted of fiv

5. Characterization of the solid residue generated in the detoxification step of sugarcane bagasse hemicellulosic hydrolysate and behavior in agricultural soils
ABSTRACT Overliming is an effective way of neutralizing and reducing the toxicity of the hydrolysates generated from acidic pretreatment of lignocellulosic biomass for ethanol production and others biotechnological products. Overliming generates a solid residue whose inadequate disposal may represent an environmental problem. This work aimed at the chemical

6. Physical and chemical characterization of sewage sludge with different proportions of diatomaceous earth
ABSTRACT The use of residues for agricultural production is an alternative for the achievement of sustainability. When mixed with diatomaceous earth (DE) from biofuel filtration, sewage sludge (SS) plays an important role as soil conditioning agent. As a result, the objective of this work was to make a DE vermicompost at different proportions: 0; 7.53; 15.06

7. How increased atmospheric carbon dioxide and ‘The Law of the Minimum’ are contributing to environmental obesity
Resumo Justus von Liebig observou que era possível aumentar a produção agrícola adicionando pequenas quantidades de nitrogênio (N), fósforo (P) e potássio (K) aos solos. Essa descoberta levou a mais recente revolução agrícola. Contudo, uma vez que a maioria das plantas e microrganismos podem ser não-homeostáticos em relação a composição quím

8. Water retention capacity in Arenosols and Ferralsols in a semiarid area in the state of Bahia, Brazil
Abstract: One of the most serious problems in areas indicated for irrigation projects in the Brazilian Northeast region is the occurrence of sandy soils, known to have low moisture retention, but occurring in strategic locations in terms of water supply and geographical situation, and which can be used for agricultural purposes. The objective of this study

9. Saline-sodic soil treated with gypsum, organic sources and leaching for successive cultivation of sunflower and rice
RESUMO A correção de solos salinos e sódicos objetiva reduzir os sais dissolvidos na solução e sódio trocável, respectivamente, possibilitando o crescimento e a produção das culturas. Neste contexto, um experimento foi desenvolvido, entre agosto/2011 e setembro/2012, em solo salino-sódico do Perímetro Irrigado de São Gonçalo, no município de So

11. Cover cropping system and mulching can shape soil microbial status in fruit orchards
ABSTRACT The use of cover crop in agricultural fields has been well elucidated, especially regarding nitrogen fixation from legume crops and their function as weed protection. Furthermore, to cover crops can benefit the soil microbial community. This study aimed to evaluate and compare the benefits of mulching and cover cropping systems on soil microbial gro

12. Synthesis of enriched biochar as a vehicle for phosphorus in tropical soils
RESUMO O fósforo (P) é um dos nutrientes que mais limita a produtividade agrícola, principalmente em solos tropicais. Biocarvão enriquecido tem sido proposto com o intuito de incrementar a biodisponibilidade de P e de outros nutrientes no solo. Assim, objetivou-se avaliar a disponibilidade do fósforo em biocarvão fosfatado (composto de biomassa e solo)
