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. Interaction of Lead and Calcium with Biochar Produced from Cassava Waste: Perspectives for Agricultural and Environmental Application
Biochar from slow pyrolysis under controlled conditions is favorable in the transformation of waste into materials that serve as soil conditioners, and/or environmental remediation. Thus, this work aimed to produce and characterize biochar from cassava waste under different temperature conditions and evaluate interactions with Ca2+ and Pb2+ for agricultural

4. 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),

5. SPATIAL VARIABILITY OF IRRIGATED COMMON BEAN YIELD CORRELATED WITH THE FERTILITY OF A SANDY SOIL
ABSTRACT The common bean is widely cultivated in Brazil. In the 2016–2017 growing season, an experiment was carried out in a Typic Quartzipsamment (or Neossolo Quartzarênico) soil in the municipality of Cassilândia, MS, Brazil, with the aim of characterizing specific aspects of soil management, using a linear and spatial correlation between the irrigated

6. REMEDIACIÓN ELECTROCINÉTICA DE UN SUELO REAL CONTAMINADO CON PLOMO ASISTIDA CON LA ADICIÓN DE UN AGENTE COMPLEJANTE
The use of ethylenediaminetetraacetic acid disodium salt (Na2EDTA) as a chelating agent presents ideal characteristics to be used for the removal of lead from a contaminated site. Batch experiments together with a simple local equilibrium model were carried out to evaluate the role of EDTA as enhancing agent in electrokinetic remediation of a Pb-contaminated

7. Effects of organic liquid fertilizers on biological activities and fruit productivity in open-field cherry tomato
ABSTRACT This study evaluated the effects of liquid fertilizers (LF) with farm-derived renewable resources on biological activities and chemical attributes of the soil and fruit in an open-field tomato (Lycopersicon esculentum var. cerasiforme) experiment conducted in South Korea in the 2019 growing season. The LF treatments included bone+fish meal (BF), fis

8. Greenhouse gas emission, water quality and straw decomposition as a function of rice postharvest field management
ABSTRACT The objective of this paper was to evaluate the quality of water drained after the use of the knife-roller (an implement used to incorporate rice residues after harvest), the partial global warming potential (pGWP) and straw decomposition as a result of postharvest field management of irrigated rice. The experiments were conducted during the 2018 an

10. Plastic soil covers in vegetative development, production and quality of strawberries
ABSTRACT The purpose this study was to evaluate the vegetative development, yield and quality of strawberry cultivars of short and neutral days as a function of soil cover. Two experiments were carried out in a protected environment. The experimental design used in both experiments consisted of randomized blocks, with subdivided plots. Harvests were carried

11. DEFICIT IRRIGATION OF SUBSURFACE DRIP-IRRIGATED GRAPE TOMATO
ABSTRACT Agriculture is one of the segments that most uses water and developments have been made to save irrigation water. Deficit irrigation is a technique that can contribute to production and water saving in agriculture. This study aimed to evaluate the viability of deficit irrigation in tomato production irrigated by subsurface drip in a greenhouse and e

12. Biorremediação de solos contaminados com arsênio por meio de lavagem de solo usando biossurfactantes
RESUMO A mineração de ouro é uma das principais fontes de contaminação de arsênio (As) no Quadrilátero Ferrífero em Minas Gerais. O As é um elemento tóxico capaz de causar sérios danos à saúde humana. Com o objetivo de investigar formas mais ecológicas e igualmente eficientes para a remoção de As em solos, empregou-se a técnica de lavagem de
