ABSTRACT- Crop-livestock-forestry (CLF) has been recommended as a strategy for soil carbon sequestration, reducing greenhouse gas (GHG) emissions of livestock as well as for sustainable soil management for improving soil organic carbon (SOC) and soil health. In this study we quantified SOC accruals in a very clayey Rhodic Ferralsol during the evolution of a 11-year-old crop-livestock-forestry system in the municipality of Cachoeira Dourada, Central West region of Brazil. CLF was implemented in 2009 in a conventional Pasture area, and soil samples were collected in 2012 and 2020 under two land uses, CLF, and the conventional Pasture as time-zero reference. The soil in CLF was evaluated within the tree lines (CLF-WL) and in the alley pasture between the tree lines (CLF-BL) having palisade grass. SOC dynamics were different in the upper 30 cm and in the underlying 70 cm layer. In the 0.0-0.3 m layer, after an initial decline in SOC stocks due to soil preparation for the implementation of CLF, SOC accumulation rates were positive in CLF (0.46-0.28 Mg ha-1 yr-1 ), but negative in the reference Pasture (-0.26). At 0.3-1.0 m SOC stocks were higher (both in 2012 and 2020) in the CLF-WL (86.70 and 83.74) than in the Pasture (71.81 and 74.96), however, CLF SOC was declining. Total soil N under CLF, compared to the reference Pasture, was lower and declining. These findings confirm that in general CLF is a valid strategy to increase SOC stocks compared to conventional Pasture, but adequate soil fertility management is necessary to potentialize SOC.
RESUMEN- Se ha recomendado a la agricultura-ganadería-silvicultura (AGS) como estrategia para el secuestro de carbono del suelo, la reducción de las emisiones de gases de efecto invernadero (GEI) del ganado, así como para el manejo sostenible del suelo para mejorar el carbono orgánico del suelo (COS) y la salud del suelo. En este estudio cuantificamos la acumulación de COS en un Ferralsol Ródico muy arcilloso durante la evolución de un sistema agrícolaganadero-forestal de 11 años de antigüedad en el municipio de Cachoeira Dourada, región Centro Oeste de Brasil. AGS se implementó en 2009 en un área de pastos convencionales, y se recolectaron muestras de suelo en 2012 y 2020 bajo dos usos de tierra, AGS y pastos convencionales como referencia de tiempo cero. El suelo en AGS se evaluó dentro de las líneas de árboles (AGS-DL) y en el pasto en callejón entre las líneas de árboles (AGS-EL) que tenía pasto en empalizada. La dinámica del COS fue diferente en los 30 cm superiores y en la capa subyacente de 70 cm. En la capa de 0,0-0,3 m, después de una disminución inicial en las existencias de COS debido a la preparación del suelo para la implementación de AGS, las tasas de acumulación de COS fueron positivas en AGS (0,46-0,28 Mg ha-1 año-1), pero negativas en la capa de referencia. Pasto (-0,26). A 0,3-1,0 m, las existencias de COS fueron mayores (tanto en 2012 como 2020) en AGS-DL (86,70 y 83,74) que en Pastizales (71,81 y 74,96), sin embargo, AGS SOC estaba disminuyendo. El N total del suelo bajo AGS, en comparación con el pasto de referencia, fue menor y disminuyó. Estos hallazgos confirman que, en general, la AGS es una estrategia válida para aumentar las reservas de COS en comparación con los pastos convencionales, pero es necesario un manejo adecuado de la fertilidad del suelo para potencializar el COS.

Genomic selection has been implemented in several plant and animal breeding programs and it has proven to improve efficiency and maximize genetic gains. Phenotypic data of grain yield was measured in 147 maize (Zea mays L.) singlecross hybrids at 12 environments. Single-cross hybrids genotypes were inferred based on their parents (inbred lines) via single nucleotide polymorphism (SNP) markers obtained from genotyping-by-sequencing (GBS). Factor analytic multiplicative genomic best linear unbiased prediction (GBLUP) models, in the framework of multienvironment trials, were used to predict grain yield performance of unobserved tropical maize single-cross hybrids. Predictions were performed for two situations: untested hybrids (CV1), and hybrids evaluated in some environments but missing in others (CV2). Models that borrowed information across individuals through genomic relationships and within individuals across environments presented higher predictive accuracy than those models that ignored it. For these models, predictive accuracies were up to 0.4 until eight environments were considered as missing for the validation set, which represents 67% of missing data for a given hybrid. These results highlight the importance of including genotype-by-environment interactions and genomic relationship information for boosting predictions of tropical maize single-cross hybrids for grain yield. |
