Delineation of management zones with soil apparent electrical conductivity to improve nutrient management
(Elsevier, 2013-11)
Site-specific management demands the identification of subfield regions with homogeneous characteristics (management zones). However, determining subfield areas is difficult because of complex correlations and the spatial ...
Nutrient Uptake and Removal by Potato Cultivars as Affected by Phosphate Fertilization of Soils with Different Levels of Phosphorus Availability
(Soc Brasileira De Ciencia Do Solo, 2017-01-01)
Studies in the past decades have focused on how tuber yield of potato grown on different types of soil is affected by phosphate fertilizer rates. However, little is known about the effects of phosphorus availability in the ...
Plasticity in root symbioses following shifts in soil nutrient availability during long-term ecosystem development
(Wiley Blackwell Publishing, Inc, 2019-03)
The vast majority of terrestrial plants form root symbioses with arbuscular mycorrhizal (AM) fungi to enhance nutrient (particularly phosphorus, P) acquisition. However, some plant species also form dual symbioses involving ...
The Argentinean Pampas: A key region with a negative nutrient balance and soil degradation needs better nutrient management and conservation programs to sustain its future viability as a world agroresource
(Soil and Water Conservation Society, 2009-09)
The soils of the Pampas region have suffered different processes of degradation and erosion. Several of the causes of this degradation are commonly found throughout the world; other causes are more particular to the Pampas, ...
Differential contribution of soil biota groups to plant litter decomposition as mediated by soil use
(PeerJ, 2015-03)
Plant decomposition is dependant on the activity of the soil biota and its interactions with climate, soil properties, and plant residue inputs. This work assessed the roles of different groups of the soil biota on litter ...
Nutrient dynamics in an Andean forest region: a case study of exotic and native species plantations in southern Ecuador
(2019)
Information about nutrient dynamics is of upmost importance in order to contribute to the restoration of degraded forest environments in the Andes of southern Ecuador. This study aims to investigate the differences of ...
Simulation of growth of managed forests in the Atlantic Zone of Costa Rica and analysis of nutrient cicling to determine surpluses and shortages
(CATIE, Turrialba (Costa Rica) Ministerio de Agricultura y Ganadería, San José (Costa Rica) Agricultural University Wageningen, Wageningen (Países Bajos), 1995)
Growth of a managed natural forest and a forest plantation in the Atlantic Zone of Costa Rica were simulated with the TROPFOR programme and the resulting organic matter flows combined with concentrations of plant components ...
Effects of litter manipulation in a tropical Eucalyptus plantation on leaching of mineral nutrients, dissolved organic nitrogen and dissolved organic carbon
(Elsevier B.V., 2014-11-01)
Although many studies have shown that soil solution chemistry can be a reliable indicator of biogeochemical cycling in forest ecosystems, the effects of litter manipulations on the fluxes of dissolved elements in gravitational ...
