Nitrogen mineralization and phosphorus solubization due to rewetting of forest and paddy soils

Annals of Tropical Research, 2010
Rewetting of soils may cause an increase in phosphorus solubilization and nitrogen mineralization resulting in the release of bioavailable phosphates and nitrate which are vital for crop growth but are also associated with eutrophication of surface ...

Effect of long-term application of manure and mineral fertilizers on nitrogen mineralization and microbial biomass in paddy soil during rice growth stages

Plant, Soil and Environment, 2009
Net N mineralization rate (NMR), net N consumption rate (NCR), microbial biomass carbon (MBC) and nitrogen (MBN), potentially mineralizable N (PMN) and mineral N (N-NH+4 and N-NO-3) were measured in paddy soil at five growth stages of rice to determine ...

Improving Nitrogen Fertilization Recommendations in Temperate Agricultural Systems: A Study on Walloon Soils Using Anaerobic Incubation and POxC

Nitrogen
Crops nitrogen supply through the in situ mineralization of soil organic matter is a critical process for plant nutrition. However, accurately estimating the contribution of mineralization remains challenging.

Mineralização de nitrogênio e carbono em solos sob plantações de eucalipto, em uma sequência de idades Carbon and nitrogen mineralization in soils under an eucalyptus plantation chronosequence

Revista Brasileira de Ciência do Solo, 2010
A estimativa da mineralização de N e de C é essencial no desenvolvimento de práticas que maximizem a eficiência no uso de N, especialmente no caso do eucalipto, que apresenta baixa magnitude de resposta à fertilização nitrogenada.

Nitrógeno de amino-azúcares en suelos: calibración y relación con el nitrógeno incubado anaeróbico Amino-sugar nitrogen in soils: calibration and relationship with anaerobically incubated soil nitrogen

Ciencia del Suelo, 2009
La determinación de los requerimientos de nitrógeno (N) para maíz se realiza en base al contenido de nitrato en suelo, pero la fracción orgánica de N puede realizar aportes significativos durante el ciclo del cultivo.

Vermifiltration and sustainable agriculture: unveiling the soil health-boosting potential of liquid waste vermicompost

Frontiers in Sustainable Food Systems
Vermifiltration is a promising technique that can help recover nutrients from wastewater for further use in agriculture. We conducted a field experiment to assess the effectiveness of vermicompost produced from the vermifiltration of liquid waste (manure

RELATIONS OF ORGANIC CARBON, TOTAL AND POTENTIALLY MINERALIZABLE NITROGEN WITH THE NITROGEN UPTAKEN BY MILLET

, 2007
The present study was carried out in greenhouse to correlate soil organic carbon (OC), total nitrogen (Nt) and potentially mineralizable nitrogen (No – estimated by the hyperbolic, simple and the double exponential models) to nitrogen uptaken by millet. Stocks of OC, Nt and No, no matter which tillage systems have been used, are closely associated with
