Soil and water impacts around re‐introduction of manure into farming systems

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 4, December 2025.
Abstract This case study seeks to assess the long‐term impact of manure usage on soil health and water under on‐farm conditions. Explicitly, we concurrently monitored nutrient concentrations in shallow groundwater (nitrogen and phosphorus) and related in‐field soil health indicators (permanganate oxidizable carbon, mineralizable C, and autoclaved ...

Effects of Land Use Change and Seasonality of Precipitation on Soil Nitrogen in a Dry Tropical Forest Area in the Western Llanos of Venezuela

open access: yesThe Scientific World Journal, 2014
We evaluated changes of different soil nitrogen forms (total N, available ammonium and nitrate, total N in microbial biomass, and soil N mineralization) after conversion of semideciduous dry tropical forest in 5- and 18-year-old pastures (YP and OP, resp.

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

open access: yesAnnals 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 ...

Comparisons of organic and conventional maize and tomato cropping systems from a long-term experiment in California [PDF]

open access: yes, 2005
Yield differences and trends, organic matter accumulation, and the loss of nutrients to deeper soil horizons are discussed using data from organic and conventional maize/tomato cropping systems from the Long Term Research on Agricultural Systems Project (

Beneficial management practices to stabilize Canadian wheat yield in a changing climate

open access: yesAgronomy Journal, Volume 117, Issue 6, November/December 2025.
Abstract Wheat (Triticum aestivum L.) remains a major staple crop, which is vulnerable to abiotic and biotic stresses that can be compounded by climate change. This review assesses the projected effects of climate change on wheat production globally with an emphasis on the Canadian Prairies.

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

open access: yesPlant, 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 ...

Nitrogen management in organic horticultural rotation [PDF]

open access: yes, 2014
A field crop rotation with a cover crop of hairy vetch (Vicia sativa, L.) and rye (Secale cereale, L.)followed by potato (Solanum tuberosum L.) and lettuce (Lactuca sativa, L.)was set up with the aim of improving nitrogen (N) management for organic ...
