Core Ideas Soybean seed inoculation with Bradyrhizobium japonicum enhances grain production. Greater response happens in Argentinean sites than the United States. Several soil properties and crop management practices are related responses to inoculation. Although relevance of biological N nutrition soybean [ Glycine max (L.) Merr.] is recognized worldwide, shows variable results benefit needs be validated under current production practices. We conducted statistical analysis field trial data...
Abstract Crop productivity under dryland conditions is largely limited by soil water availability. Soil organic matter (SOM) contents have been found to be a reliable index of crop in semiarid regions because it positively affects water‐holding capacity. Our objectives were explain differences wheat ( Triticum aestivum L.) yields response SOM levels and related properties quantify the contribution unit increment content during 1991, 1992, 1994 on total 134 production fields Argentine Pampas....
The development of well‐structured soils is a goal for achieving sustainable and productive agricultural systems. Nevertheless, the maintenance soil structure in continuous no‐till (NT) has sometimes been thought to induce conditions that are detrimental crop yields. objectives this research were characterize effects periodic tillage disruption otherwise NT systems on properties yields winter wheat ( Triticum aestivum L.), double‐cropped soybean [ Glycine max (L.) Merr.], maize Zea mays L.)...
Nitrogen availability and drought influence wheat ( Triticum aestivum L.) grain yields in the semiarid subhumid Pampas region of Argentina. The application fertilizers containing osmoprotectants, such as glycinebetaine, to crop canopies might reduce losses caused by environmental stresses. objectives this study were (a) determine effects on foliar a commercial fertilizer with (b) establish, under farmers’ field conditions, relation between soil properties productivity crops treated same...
Abstract Organic carbon (C) levels in a Typic Hapludoll under four management systems [moldboard plowing, chisel no‐tillage, and perennial fescue (Festuca arundinacea) pasture] were determined by two methodologies: wet oxidation with potassium dichromate (K2Cr2O7) dry combustion analyzer. The correlation between organic C obtained both methodologies (r=0.87, n=48, p<0.01) rose when agricultural pasture considered separately. Carbon recovered Walkley‐Black method was 15% lower than that the...
Abstract In semiarid regions the availability of water has an important influence on dryland crop productivity. Water is closely related to soil organic matter (SOM) content, texture and thickness. Safflower (Carthamus tinctorius L.) winter in some due its deep roots drought tolerance. However, adaptation different conditions still not well known. The objective this study was evaluation safflower productivity, relation properties, across 30 grower fields Pampas region Argentina. soils were...
Biological nitrogen fixation (BNF) is of key importance in the N balance soybean (Glycine max) crops. A number authors have suggested that a negative may occur under high yield conditions. Few studies measured contribution BNF to soil pampas region. The aims present study were compare three determination methods – two isotopic using sorghum or non-nodulating isoline as reference crop, and one involving calculation difference content between nodulating isolines estimate crops raised...
We combined water activity meters and fractal modeling to facilitate rapid, physically based characterization of the soil retention curve. Desorption data (6 points per sample) were collected in tension ( h ) range 2.0 × 10 2 1.5 5 kPa using gravimetric method measure content w Thirty‐two disturbed samples from a long‐term nitrogen fertilization tillage comparison study on silt loam analyzed. A new form an established equation was derived: = ah D− 3 − ρ / s , where is compound parameter...
The soils from the sandy Pampas region (Argentina) are coarse‐textured Mollisols with high to very extractable K levels. However, in several KCl fertilization field trials, wheat ( Triticum aestivum L.) grain yield and alfalfa Medicago sativa dry matter production increments have been reported. Our objective was determine contribution of Cl − on dryland spring productivity. study performed during 2001 2002 growing seasons 10 experimental sites establishing 14 treatments completely randomized...
Distributions of soil fragments (a mixture primary aggregates resulting from tillage fragmentation) in seedbeds are known to influence emergence and early shoot root growth crops. However, it is not clearly understood which distribution model parameters the roots responding when water imbibition nutrient availability limiting factors. The objective this study was determine effect(s) variation geometric mean diameter (GMD) log standard deviation (LogGSD) taken a log‐normal fragment size on...
