Cover crops in the Southeastern region of Buenos Aires, Argentina: effects on organic matter physical fractions and nutrient availability
(Springer Verlag, 2018-06)
In the Southeastern region of Buenos Aires province, soybean monoculture has led to a decline in soil organic matter (SOM) levels in soil, mostly the labile fractions. The reduction of SOM has a negative impact on the soil ...
Soil aggregation according to the dynamics of carbon and nitrogen in soil under different cropping systems
(Empresa Brasil Pesq Agropec, 2016-09-01)
The objective of this work was to evaluate total soil carbon and nitrogen, as well as their contents in particulate and mineral-associated C fractions; to determine C stock and sequestration rates in the soil; and to verify ...
Soil organic carbon in cropping sequences with predominance of soya bean in the argentinean humid Pampas
(Wiley Blackwell Publishing, Inc, 2020-01)
Soya bean (Glycine max (L.) Merr.) monoculture can lead to a decrease in labile fractions of soil organic carbon (SOC). This study sought to evaluate the effects of cover crops (CC), application of fertilizer, and crop ...
Seasonal patterns of organic matter stoichiometry along a mountain catchment
(Springer, 2016-05)
Organic matter (OM) nutrient content is expected to change as OM is transported from upstream forested reaches downstream to open land, and these changes could depend on seasonal patterns. The aim of this study was to ...
