Active crop sensor to detect variability of nitrogen supply and biomass on sugarcane fields
(SPRINGERDORDRECHT, 2012)
Nitrogen management has been intensively studied on several crops and recently associated with variable rate on-the-go application based on crop sensors. Such studies are scarce for sugarcane and as a biofuel crop the ...
Effect of different cover crops on C and N cycling in sorghum NT systems
(2016)
In many no-till (NT) systems, residue input is low and fallow periods excessive, for which reasons soil degradation occurs. Cover crops could improve organic matter, biological activity, and soil structure. In order to ...
Effects of soil water deficit and nitrogen nutrition on water relations and photosynthesis of pot-grown Coffea canephora Pierre
(2002-12-01)
Coffea canephora plants (clone INCAPER-99) were submitted to low N (LN) or high N (HN) applications and two watering regimes (daily irrigation and irrigation every 5 days for a month). Although water potential was not ...

Mechanisms of nitrogen conservation at the leaf-level in annual and perennial desert forbs: Implications for perennial crops domestication
(Elsevier Gmbh, 2019-03)
Perennial plants show traits such as long-lived leaves and higher nutrient retention that provide a more efficient use of nutrients in low-resource environments when compared to annuals. These traits do not only generate ...
Ultramicropore-influenced mechanism of oxygen electroreduction on metal-free carbon catalysts
(Royal Society of Chemistry, 2019-11)
Two series of microporous carbon catalysts were prepared from ordered mesoporous carbon obtained from sucrose and KIT-6 as a carbon source and template, respectively. To modify surface features, the mother sample carbon ...
Mulching films affecting soil bacterial and fungal communities in a drip-irrigated potato soil
(Revista Brasileira de Ciência do Solo, 2022)
Organic farming does not increase soil organic carbon compared to conventional farming if there is no carbon transfer from other agroecosystems: A meta-analysis
(Csiro Publishing, 2021-11)
Context: Organic farming is based on the non-use of synthetic fertilisers and pesticides. Nitrogen inputs are derived from symbiotic fixation and organic fertilisers, which also contribute carbon to the agroecosystem. Soil ...
