Evaluation of potentially available nitrogen by biological and chemical methods in soil cultivated with maize in succession to cover crops
(2022-01-01)
Estimating mineralization rates is one of the best ways to predict N availability over time. However, different methods can lead to distinct predictions, especially when different production systems are used. The aim of ...
Grain sorghum grown as second crop and inoculated with Azospirillum brasilense associated with nitrogen fertilizationSorgo granífero em segunda safra inoculado com Azospirillum brasilense associado a adubação nitrogenada
(2021-07-01)
Nitrogen fertilization in off-season sorghum may have lower cost-benefit ratios than expected due to the residual effect of previous crops. However, the use of growth-promoting bacteria can be an economical alternative to ...
Crop diversification strategy to improve economic value in Brazilian sugarcane production
(2018-07-01)
Crop diversity is beneficial to rural properties in terms of reducing business risks and increasing agricultural revenues. In sugarcane (Saccharum spp) farming, crop diversity using rotation or succession planting remains ...
Nitrogen Supply for Cover Crops and Effects on Peanut Grown in Succession under a No-Till System
(Amer Soc Agronomy, 2009-01-01)
In Brazil, as no-till (NT) crop management expands, there is an increased interest in growing peanut (Arachis hypogaea L.) with this system. However, it is not known if the preceding cover crop species, the amount of straw ...

Crop systems and topdressing nitrogen on grain yield and technological attributes of common bean under no-tillage
(Univ Federal Goias, 2019-01-01)
Common bean has been the main crop in succession to corn and Brachiaria in no-tillage systems, in the Brazilian Savannah. This study aimed to evaluate the influence of crop systems and topdressing nitrogen on grain yield ...
Effects of long-term no-tillage systems with different succession cropping strategies on the variation of soil CO2 emission
(2019-10-10)
The optimization of conservationist production systems, whose goal is to increase carbon stocks and reduce greenhouse gas emissions, is considered one of the greatest challenges faced by agriculture nowadays. Therefore, ...
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 ...
