Multiresidue method for trace pesticide analysis in honeybee wax comb by GC-QqQ-MS
(2017-01-15)The aim of this analytical study is to develop an improved multi-residue methodology of high sensitivity and expanded scope for pesticide residue analysis in honeybee wax combs. The method was validated for 160 pesticide ... -
Increased cropping intensity improves crop residue inputs to the soil and aggregate-associated soil organic carbon stocks
(Elsevier, 2017-01)Many South American agroecosystems are based mainly on soybean [Glycine max (L.) Merr.] as a sole crop in the year, which has increased concerns regarding soil conservation and ecosystems sustainability. The increase in ... -
Vertical distribution of root biomass and soil carbon stocks in forage cropping systems
(Springer, 2018-02)Background and aims: Forage cropping systems may differentially affect the vertical distribution of roots and soil organic C stock (C-OM). In annual crops sequences (ACS) and perennial pastures (PP), we assessed the ... -
Development and evaluation of an automatic software for management zone delineation
(2018-06)The lack of availability of user-friendly and automatic software for management zone delineation is limiting the adoption of site-specific management practices. Several procedures for management zone delineation have been ... -
