Abstract Knowledge of the structure-property-function relationship humic substances (HSs) is key for understanding their role in soil. Despite progress, studies on this topic are still under discussion. We analyzed 37 fractions with respect to isotopic composition, structural characteristics, and properties responsible stimulating plant root parameters. showed that regardless source origin carbon (C 3 or C 4 ), soil-extracted HSs acids (HAs) structurally similar each other. The more labile...
Agroforestry systems have been promoted as a solution to address trade-offs between environmental conservation efforts and the need for increased agricultural productivity on smallholder farms in Brazil. However, impact of land use change from degraded pasture agroforestry soil properties remains unclear. The objectives this research were to: (1) assess chemical, physical biological across distinct uses (degraded pasture, secondary forest); (2) understand relationships litter quality,...
Soil salinization is a significant abiotic factor threatening agricultural production, while the low availability of phosphorus (P) in plants another worldwide limitation. Approximately 95–99% P soil unavailable to plants. Phosphate-solubilizing bacteria (PSB) transform insoluble phosphates into soluble forms that can utilize. The application PSB replace or partially reduce use fertilizers. Therefore, selecting with high solubilization capacity from extreme environments, such as saline...
This study had as its objective to evaluate the effects of different tillage and crop systems on growth productivity sugarcane plants. The experiment was conducted in Linhares, ES. It is one oldest assays country investigating unburned burned sugarcane. Installed a Yellow Latosol with sandy/medium texture, treatments consisted plots (conventional minimum tillage) subplots (raw sugarcane). Plant growth, contribution organic matter quantification yield were evaluated. diameter larger for...
Our main goal was to investigate the potential accumulation of fluoroquinolones (FQs) in agricultural soils over extended periods land use, predicting leaching and estimating risk quotients for soil microorganisms. Short long-term poultry litter fertilization (<1-30 years) were evaluated enrofloxacin (ENR) ciprofloxacin (CIP) input, addition emergence plasmid-mediated quinolone resistance (PMQR) genes. High FQs concentration (range 0.56-100 mg kg-1) measured samples. In soils, occurrence...
Abstract Most deforested lands in Brazil are occupied by low-productivity cattle ranching. is the second biggest meat producer worldwide and projected to increase its agricultural output more than any other country. Biochar has been shown improve soil properties productivity when added degraded soils, but these effects context-dependent. The impact of biochar, fertilizer inoculant on forage grasses ( Brachiaria spp. Panicum spp.) was investigated from environmental socio-economic...
Large amounts of waste, such as those generated during offshore well drilling and sewage treatment, pose environmental challenges due to risks human health soil contamination when improperly disposed of. The present study aimed evaluate the feasibility using cuttings sludge together produce an organomineral fertilizer (OMF). effects on quality, waste properties, agronomic efficiency OMF in corn plants were evaluated. results indicated that gravel particle size (<0.25 mm) favours mineral...
Introduction The effect of co-inoculation with plant growth-promoting bacteria on the microbiome soybean roots was investigated in a field experiment. Soybean plants were inoculated Bacillus subtilis , aryabhattai Streptomyces sp., and Saccharopolyspora spinosa compared to control treatment that received mineral fertilization. Methods yield parameters endophytic evaluated. Results No significant differences observed among treatments, suggesting microbial inoculation can serve as an...
The application of biochar as a soil amendment has garnered significant interest due to its potential enhance fertility, promote plant growth, and contribute sustainable agriculture. This study investigated how the structural morphological characteristics artisanal biochars from four different brands (AB1, AB2, AB3, AB4), purchased in supermarkets, influence development rice plants sandy soil. Spectroscopic analyses demonstrated that AB4 exhibited highest aromaticity (77%), ensuring...
Novas tecnologias com o intuito de minimizar as perdas N-NH3 por volatilização devem ser desenvolvidas para aumentar a eficiência uso do N-ureia. A incorporação boro e cobre na ureia pode reduzir esses efeitos meio da inibição atividade urease. O experimento foi conduzido em casa vegetação, onde foram aplicados diferentes fertilizantes nitrogenados (ureia pastilhada sem cobre, sulfato amônio, inibidor urease NBPT, granulada revestida cobre) superfície um Planossolo Háplico contido bandejas...
The objective of this study was to evaluate the accumulation fresh weight hydroponic lettuce in terms ionic concentrations and flow rates nutrient solution. This work consisted three experiments NFT system, conducted between July September 2006. Lettuce cultivars Lucy Brown, Izabela Veneza were grown different 100, 75 50% 1.50, 1.00 0.75 L min-1. Fresh gains observed for Brown when on 100% ion concentration a rate solution 1.0 Greater mass cvs. under 1.5 A general analysis data allows us...
Reducing soil degradation and its impacts on the environment have been one of main challenges 21st century, exacerbated by a direct link between increases in human population that raises current future food security concerns. Despite this, experiences worldwide reveal degraded land restoration projects either achieved little success or failed. Thus, understanding underlying causes devising appropriate mechanisms is crucial. Soil amelioration using beneficial microorganisms, particularly...
This study aimed to apply statistical response surface models (RSMs) evaluate morphological parameters of plant root system changes in humic acid (HA). The was carried out a growth chamber. Experimental treatments consisted HA extracted using IHSS methodology at increasing doses: 0, 20, 40, 60, 80, 110, and 150 mg L−1. Seedlings were collected 24, 48, 72, 96, 120 144 h, the rice analyzed with WinRHIZO software. Different systems analyzed. stimulation pattern doses on morphology seedlings...
No-tillage (NT) has been adopted in organic agriculture as an alternative to conventional tillage (CT) for improving soil conservation. Cover crops (CC) play a vital role this process by providing straw and releasing nutrients into the soil. Therefore, study, we aimed evaluate effects of NT CT management on chemical properties bacterial diversity following cultivation diverse CC system. The experiment was conducted using randomized block design with subdivided plots, wherein plots...
O manejo de resíduos orgânicos sob condições anaeróbias pode, durante a fase inicial do processo metabólico, levar à formação ácidos voláteis (C1-C4), cuja atividade fitotóxica determina perdas substanciais produção vegetal. A caracterização da fitoxidez desses foi o objetivo presente revisão. tipo e quantidade dos produzidos dependem, basicamente, qualidade resíduo adicionado, sendo fitotoxidez diretamente relacionada ao comprimento cadeia carbonos concentração pH meio em que se encontram....
