Soil analysis is used to estimate nutrient availability, but concentrations are not always related yield in most fruit plants, including grapevines. Thus, additional multivariate mathematical models, such as the compositional diagnosis (CND), which takes into account leaves concentration, and yield, can contribute estimating critical levels or sufficiency bands of elements, well detect deficiency and/or excess nutrients. The aim present study was establish CND standards, level band...
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...
A significant quantity of nutrients in vineyards may return to the soil each year through decomposition residues from cover plants. This study aimed evaluate biomass and nutrient release black oats hairy vetch deposited vines rows, with without plastic shelter, between-row areas throughout vegetative productive cycle The was conducted a commercial vineyard Bento Gonçalves, RS, Brazil, October 2008 February 2009. Black oat (Avena strigosa) (Vicia villosa) were collected, subjected chemical...
Abstract The processes involved in deformation, internal strength and stability of soils with long‐term application fertilizers (organic inorganic sources) remain poorly investigated hence understood, particularly agricultural systems under subtropical climatic conditions. We how fertilizer management organic amendments no‐till crops affects the microstructural a sandy Alfisol oscillatory shear. study was conducted southern Brazil on 17‐year completely randomized block experiment five...
Soils with a long-term history of animal manure application exhibit higher residual effects nitrogen (N) in soil and can affect the efficiency which N will be used. This study aimed to evaluate how immediate effect 16 applications reflects on yields black oat corn rotation system, as well use efficiency. The was carried out no-tillage from 2004 2016 Brazil. treatments were pig [...]
Copper (Cu) and zinc (Zn) fraction accumulation adsorption capacity were evaluated in sandy-soil after 16 pig slurry (PS) deep-litter (DL) applications under subtropical climate. Sixteen PS DL to a Typic Hapludalf increased soil Cu Zn soluble, exchangeable, mineral, organic, total fractions. mostly accumulated organic residual fractions (1.03, 4.39, 9.81, 9.68, 12.9, 13.98 mg kg−1 the control, PS, DL, respectively), whereas presented greater increase mineral exchangeable (0.42, 6.39, 15.46...
Copper (Cu) contents in vineyard soils due to the application of cupric fungicides cause changes native covering flora. Under these conditions, surviving individuals accumulate metal and decrease its availability soil, reducing potential toxicity grapevine. We have identified spontaneous plant species their phytoremediation from vineyards Isabella (Vitis labrusca) on two distinct soil types (Inceptisol Entisol) contaminated with Cu. The results demonstrated that wild displayed higher Cu...
Injection of pig slurry (PS) into soils under no-tillage system (NTS) is more efficient for improving soil chemical and physical attributes, reducing C N emissions, than surface applications. This study evaluated the effect using injection application PS, compared to NPK control treatments, on aggregate, contents, isotopes 13C 15N. The NTS consisted rotations summer (maize) winter (black oat wheat) grasses from 2011 2015. treatments were PS injected (PSI), applied (PSS), fertilization (NPK),...
Soil erosion in Brazil is very high, and there need to promote aggregate stability technics increase the soil organic matter water infiltration, with a consequent decrease processes. Applications of animal manure on sandy loam may carbon (C) nitrogen (N) contents aggregates, causing increased stability. This study aimed evaluate total (TOC) (TN) as well physical properties subjected 11 years application mineral fertilizer. The experiment was conducted under no-tillage (NT) system corn...
Los suelos arenosos de la región Campanha Gaúcha son naturalmente bajos en contenidos fósforo (P) disponible, por lo que requiere una atención especial con fertilización previo a siembra. Sin embargo, aún no existen trabajos investigación permitan calibración adecuada para determinar el contenido P disponible cultivo vides viníferas jóvenes. El objetivo esta fue evaluar fosfatada las variedades jóvenes vid Chardonnay y Pinot Noir fin sugerir dosis recomendación P, arenosos. En Octubre 2011...
