ABSTRACT. - Short-term solutions like increasing N fertilization and decompaction with deep tillage (DT) have been proposed to mitigate soil degradation in continuous cropping systems. However, the joint evaluation of these factors in established no-till systems is limited. This work aims to quantify corn yield losses generated by the cumulative degradation of soil quality of intensified no-till cropping systems, quantify to what extent yield losses could be mitigated by soil DT and N fertilization, and identify the most important process involved in yield reductions. Eleven experiments were installed during 2014 and 2015, on a typic Argiudoll with different soil quality generated by more than 50 years of contrasting land uses. A split-plot design was employed; the main plots were for DT (with and without) whereas the subplots were four N rates (0, 60, 120, and 240 kg ha?1). Overall, soil physical quality (SPQ) and carbon losses were associated with yield depletions. An increase in bulk density of 0.1 g cm?3 was associated with a 15.8% yield decrease. Deep tillage improved SPQ and modified water and N dynamics. However, these changes were small, variable, and did not affect corn growth. N fertilization improved yields but did not eliminate differences linked with land degradation and previous crop effects. Soil organic carbon had a better association with yields than bulk density, macroporosity, and penetration resistance. The results of this study highlight the importance of evaluating remediation practices to soil degradation under real conditions, regardless of its greater complexity for interpretation.

Uruguayan meat production systems are based mainly on grazing pastures. More intensive systems have been growing by adding concentrate to grazing animals to improve performance and beef carcass and meat quality. Thirty two Hereford steers of 20 months of age, were randomly assigned to 4 treatments as a result of combining 2 levels of forage allowance (LFA: 2% and 4% of live weight LW) and supplementation (S: 0.8 and 1.6 % of ground sorghum), where: T1 = 4 % LFA + 0 % S; T2 = 2 % LFA + 0 % S; T3 = 2 % LFA + 0.8 % S and T4 = 2 % LFA + 1.6 % S. Steers from T1 and T4 produced heavier carcasses (HCW) and higher back fat thickness (BFT). When HCW is adjusted by final live weight (FLW) the differences disappeared, showing that differences were due basically for different final weight. Same tendency was observed for the weight of the most valuable meat cuts. Treatments did no affect (P>0.05) ultimate pH, intramuscular fat, meat color at 48 hours after slaughter, tenderness of meat aged for 7 and 20 days. No treatment differences on PUFA concentration and PUFA/SFA and n6/n3 ratio were found. However, meat of T4 animals presented the higher concentration of MUFA, particularly oleic fatty acid. Meat of treatments based only on pasture (T1 and T2) presented the higher concentration of linolenic and stearic fatty acids. Meat produced on grass-fed or combined with low supplement levels, could promote human health. |
