No-till and unpuddled mechanical transplanting of rice
(IRRICIMMYT, 2014)
Acidity and Aluminum Speciation as Affected by Surface Liming in Tropical No-Till Soils
(SOIL SCI SOC AMER, 2010)
Aluminum toxicity is one of the major soil factors limiting root growth in acidic soils. Because of the increase in organic matter content in the upper few centimeters of soils under no-till systems (NTS), most Al in soil ...
Co-accumulation of microbial residues and particulate organic matter in the surface layer of a no-till Oxisol under different crops
(Pergamon-Elsevier B.V. Ltd, 2012-07-01)
In the absence of significant mechanical disturbance such as under permanent no-till (NT), crop type should be a prominent factor controlling soil organic C (SOC) pools. Microbial cell residues have been shown to be ...

(Pergamon-Elsevier B.V. Ltd, 2012-07-01)
In the absence of significant mechanical disturbance such as under permanent no-till (NT), crop type should be a prominent factor controlling soil organic C (SOC) pools. Microbial cell residues have been shown to be ...
Modulation of the soil microbiome by long-term Ca-based soil amendments boosts soil organic carbon and physicochemical quality in a tropical no-till crop rotation system
(2021-05-01)
Unsustainable agricultural management practices such as non-conservationist tillage and overuse of fertilizers result in soil acidity and, in turn, soil degradation due to reduced carbon (C) concentrations and nutrient ...
Comparative analysis of exchangeable aluminum in a tropical soil under long-term no-till cultivation
(2022-02-01)
Aluminum toxicity is a key determinant of crop yield for acid soils. Techniques used to characterize a soil's exchangeable Al content often yield discordant results, thus impeding the implementation of corrective measures. ...
Phosphorus fractions in Brazilian Cerrado soils as affected by tillage
(Elsevier B.V., 2014)
Preparo do solo, inoculação de sementes e doses de nitrogênio em cobertura no feijoeiro comum de inverno irrigado
(2011-05-01)
Common bean is a demanding plant in nutrients, mainly in relation to nitrogen. The adoption of a management system that improves the soil conditions, associated to the appropriate nitrogen supply can be very important to ...
Cover crops at soybean agronomic performance in the western region of Parana state, Brazil
(Univ Federal Rural Pernambuco, 2022-01-01)
Soybean crop is one of the main activities of Brazilian agribusiness, grown in practically all regions of the country. Even though it is of fundamental importance, the no-till system is fully adopted in a few situations. ...
