“…Cultivar UFSMFW 2202 has an early, significantly shorter cycle than the control cultivars. In crop rotation systems, an early cycle is advantageous, for allowing anticipated sowing of the subsequent crop, and because the high-quality straw left on the soil is abundant and releases nutrients (Melo et al 2011). In addition, cv.…”

“…The main use of this crop is as ground cover, to improve the soil chemical, physical and biological properties in the period before summer crop sowing. According to Melo et al (2011), the dry matter yield potential and soil nutrient extraction of black oat are outstanding and can benefit subsequent crops. As reported by Carneiro et al (2008), ground cover crops are essential to protect the soil against erosion and to suppress weeds.…”

“…According to Carneiro et al (2008), black oat protects the soil against weeds and erosion. The early cycle is important in crop rotation, anticipates the subsequent crop and still leaves straw in the soil which is a source of nutrients (Melo et al 2011). UFSMFM 2101 was selected for a specific region, being adapted to the region.…”

“…Moreover, grasses (Poaceae) have high yield and large root systems. Thus, black oat (Avena strigosa Schreb) begun to be adopted by farmers in the study region and included in crop systems to increase soil cover (BARRADAS et al, 2001;MELO et al, 2011), mainly between crop seasons.…”

Biogenic and Physicogenic Aggregates Under Different Crops With Black Oat in Nova Friburgo, Brazil

et al. 2020

ABSTRACT The objective of this study was to evaluate the efficiency of black oat (Avena strigosa Schreb) crops in recovering soil aggregation, and quantify the nutrient contents in aggregates considering their formation pathways (biogenic and physicogenic) in crop areas in a mountains environment in the municipality of Nova Friburgo, RJ, Brazil. The landscape was stratified into two sections for the study: upper, two areas with black oat crops, one fertilized and one not fertilized one not fertilized, and one adjacent forest area representing the original soil conditions; and lower: one fertilized area with black oat, and one fertilized area with black oat intercrops with oilseed radish (Raphanus sativus L.) and vetch (Vicia sativa L.), and one adjacent forest area representing the original soil conditions. The aggregates were separated according to their formation pathways, quantifying the weight percentage of each formation pathway. The aggregate stability and nutrient and organic carbon contents were evaluated. The fertilized area in the upper section had the highest biogenic aggregate percentage, which was associated with the highest total organic carbon contents, and soil fertility. This area also had the highest weighted mean diameter (WMD) and geometric mean diameter (GMD) of aggregates. The intercrop area in the lower section had the highest biogenic aggregate percentage and the lowest P, Ca+2, Mg+2, and K+ contents in the aggregates. The management systems affected the aggregate formation pathways. Morphological classification is an important tool for the monitoring of soil management. The black oat crops increased the biogenic aggregate formation, which become reservoir of nutrients.
