Effects of wastewater from a cassava industry on soil chemistry and crop yield of lopsided oats (Avena strigosa Schreb.) [PDF]

Brazilian Archives of Biology and Technology, 2010
This experiment was carried out in the Arenito soil of the Cidade Gaúcha county, Northwest Paraná in Brazil, in which 0, 150, 300, 450 and 600 m³ ha-1 of wastewater were applied onto soil and the crop yield and soil chemistry were investigated for lopsided oat (Avena strigosa Schreb.) plants. The crop yield from the control was 2818 kg ha-1 contrasting

Phosphate system fertilization in no-tillage Oxisols: Effects of temporal, horizontal, and vertical distribution of available phosphorus in the soil. [PDF]

J Environ Qual
Abstract System fertilization enhances logistics and phosphorus (P) use efficiency, but its effects in high P‐export systems, particularly regarding fertilization timing, placement, and distribution, remain unclear. This study evaluated P fertilization timing (90, 45, and 0 days before winter crop sowing [DBS]), placement (banded vs.

Inundation impacts on diversified pasture biomass allocation and soil particulate organic matter stocks

Grass and Forage Science, Volume 78, Issue 4, Page 563-577, December 2023., 2023
Abstract Natural soil inundation caused by frequent and intense precipitation affects carbon allocation in grassland biomass, ultimately leading to changes in soil carbon storage. Increasing forage diversity could provide resiliency to inundation of grassland.

Rye planting date impacts biomass production more than seeding rate and nitrogen fertilizer

Agronomy Journal, Volume 115, Issue 5, Page 2351-2368, September/October 2023., 2023
Abstract Management is critical to maximize cover crop benefits, while minimizing costs. However, cover crop performance and cost can vary without consistent management strategies. Therefore, we investigated how four planting dates (late October, early November, late November, and early December), two seeding rates (67 and 101 kg ha−1), and four N ...

Cover crop planting practices determine their performance in the U.S. Corn Belt

Agronomy Journal, Volume 115, Issue 2, Page 526-543, March/April 2023., 2023
Abstract Cover crop growing periods in the western U.S. Corn Belt could be extended by planting earlier. We evaluated both pre‐harvest broadcast interseeding and post‐harvest drilling of the following cover crops: (a) cereal rye (Secale cereale L.) [RYE]; (b) a mix of rye + legumes + brassicas [MIX1], (c) a mix of rye + oat [Avena sativa L.] + legumes +

Grazing intensity and nitrogen fertilization effects on biomass and morphology of black oat roots in an integrated crop–livestock system

Agronomy Journal, Volume 115, Issue 2, Page 512-525, March/April 2023., 2023
Abstract Grazing stimulates root and forage mass of perennial pastures, but few studies have addressed the effects of grazing on annual pastures which are often grown in short periods within integrated crop–livestock systems (ICLS). In these pastures, N fertilization is a common practice to increase forage mass, but its effects on root morphology are ...

Finding the right mix: a framework for selecting seeding rates for cover crop mixtures

Ecological Applications, Volume 32, Issue 1, January 2022., 2022
Abstract Cover crop mixtures have the potential to provide more ecosystem services than cover crop monocultures. However, seeding rates that are typically recommended (i.e. seeding rate of monoculture divided by the number of species in the mixture) are non‐optimized and often result in the competitive species dominating the mixture, and therefore ...

The medium‐term impacts of integrated crop–livestock systems on crop yield and economic performance

Agronomy Journal, Volume 113, Issue 6, Page 5207-5221, November/December 2021., 2021
Abstract Integrated crop–livestock (ICL) systems are diverse production systems that can improve resource utilization through spatially or temporally rotating land among crop, livestock, and pasture uses. However, research on whether the enhanced resource utilization translates to greater crop productivity is still warranted.
