O feijão (Phaseolus vulgaris L.) é um dos principais constituintes da dieta do brasileiro, por ser excelente fonte protéica e, portanto, produto agrícola de grande importância econômico-social. A interação feijoeiro com bactérias fixadoras N atmosférico pode aumentar a produtividade e diminuir os custos produção. No presente trabalho, avaliou-se, no campo, eficiência agronômica estirpes previamente selecionadas rizóbio em simbiose o feijoeiro, comparadas à estirpe recomendada para produção...
No-till farming and manure application are means of storing carbon in soil increasing quality. However, the organic fertilization no-till soils may sustain subtropical agroecosystems for only a limited period until quality declines. The C, N, P, other nutrient cycles perturbed due to imbalance manures their on surface, which poses risk dispersion into environment. Long-term N-based also impacts apparent recovery (ANR) by crops and, hence, crop Our objective was monitor changes measure from...
Phosphorus (P) is an essential element for plant growth and development. Studies show that up to 90% of phosphorus applied via inorganic fertilizer adsorbed or precipitated into colloids not made available plants. In this context, the use microorganisms as promoters P availability in soil solution essential. The objectives work were delimit management zones (MZ) based on spatial variability content investigate effects supply, from different sources (mineral biological) each ZM, soybean crop...
Cowpea (Vigna unguiculata) cultivation in northern and northeastern Brazil provides an excellent source of nutrients carbohydrates for the poor underprivileged. Production surplus leads to its consumption other regions also as export commodity. Its capacity establish relationships with atmospheric nitrogen-fixing bacteria is crucial reduction production costs environmental impact nitrogen fertilizers. This study assessed symbiotic efficiency new strains cowpea their tolerance pH aluminum....
Successive applications of pig slurry and deep litter may lead to an accumulation copper (Cu) zinc (Zn) fractions in the soil profile. The objective this study was evaluate Cu Zn forms a Sandy Typic Hapludalf after long-term application litter. In March 2010, eight years initiating experiment Braço do Norte, Santa Catarina (SC), Brazil, on soil, samples were collected from 0-2.5, 2.5-5.0, 5-10 10-15 cm layers treatments consisting no manure (control) with at two levels: single double rate N...
High copper (Cu) levels in uprooted old vineyard soils may cause toxicity transplanted young vines, although such be reduced by inoculating plants with arbuscular mycorrhizal fungi (AMF). The objective of this study was to evaluate the effects AMF on plant growth, chlorophyll contents, colonization, and Cu phosphorus (P) absorption vines cultivated a soil contaminated Cu. Commercial high placed plastic tubes which were inoculated six species (Dentiscutata heterogama, Gigaspora gigantea,...
This work examined the capability of Imperata cylindrica to respond, tolerate and accumulate Cu when growing at high concentration (300 mg kg−1 substrate) different times exposure (2, 14 21 days). The accumulation in plants was by atomic absorption spectroscopy (AAS) localized Scanning Electron Microscopy-Energy Dispersive X-Ray spectroscopy. Additionally, phenolic compound identifications concentrations were determined using liquid chromatography coupled mass spectrometry. Our results...
In potato (Solanum tuberosum) crops, the use of fungicides to control some diseases is widespread; however, it has been reported that this practice can modify polyphenolic content, and new strategies oriented defense system are necessary. One alternative arbuscular mycorrhizal fungi (AMF) improve mechanisms plants. study, phenolic profiles antioxidant activities in leaves three genotypes (CB2011-509, CB2011-104, VR808) were evaluated crops inoculated with AMF strains (Claroideoglomus...
Pig slurry (PS) represents an important nutrient source for plants and using it as fertilizer makes greater cycling in the environment possible. The aim of this study was to assess how PS application over a period years can affect grain yield, dry matter production accumulation commercial cover crops. experiment carried out experimental area Universidade Federal de Santa Maria, RS, Brazil, from May 2000 January 2008. In period, 19 crops were grown with before sowing, at rates 0, 20, 40 80 m³...
The application of animal manure to soil can increase phosphorus availability plants and enhance transfer the nutrient solution drained from surface or leached into profile. aim this study was evaluate effect successive applications organic mineral sources on available content, runoff leaching P forms in a Typic Hapludalf no-tillage systems. Experiment 1 set up 2004 experimental area UFSM, Santa Maria (RS, Brazil). treatments consisted of: control (without application) pig slurry (PS),...
Management of biological nitrogen fixation in common bean still requires improvement. The objective this study was to verify the compatibility fertilization with N2 increase yield and profitability. Four field experiments were performed four municipalities Minas Gerais, Brazil, during 2009 2010 winter crop season. set up under a no-till system conducted using conventional tillage. A randomized block experimental design used replications seven treatments combining application rates mineral N...
ABSTRACT The application of foliar fungicides in vineyards and orchards can increase soil concentration heavy metals such as copper (Cu) zinc (Zn), up to the toxicity threshold for fruit trees cover crops. However, some agronomic practices, liming, addition organic fertilizers, cultivation crops inoculation young plants with arbuscular mycorrhizal fungi decrease availability potential metal trees. This review aims compile present information about effects increasing concentrations metals,...
