A sensitivity analysis of the prediction of the nitrogen fertilizer requirement of cauliflower crops using the HRI WELL_N computer model [PDF]

open access: yes, 2001
HRI WELL_N is an easy to use computer model, which has been used by farmers and growers since 1994 to predict crop nitrogen (N) requirements for a wide range of agricultural and horticultural crops.

Sources of nitrogen for winter wheat in organic cropping systems [PDF]

open access: yes, 2013
In organic cropping systems, legumes, cover crops, residue incorporation, and manure application are used to maintain soil fertility, but the contributions of these management practices to soil nitrogen (N) supply remain obscure.

Soil biological quality of grassland fertilized with adjusted cattle manure slurries in comparison with organic and inorganic fertilizers [PDF]

open access: yes, 2009
We studied the effect of five fertilizers (including two adjusted manure slurries) and an untreated control on soil biota and explored the effect on the ecosystem services they provided.

Microbial carbon mineralization in tropical lowland and montane forest soils of Peru [PDF]

open access: yes, 2016
Climate change is affecting the amount and complexity of plant inputs to tropical forest soils. This is likely to influence the carbon (C) balance of these ecosystems by altering decomposition processes e.g., "positive priming effects" that accelerate ...

Effects of Temperature and Moisture on Soil Organic Carbon Mineralization

open access: yesIOP Conference Series: Materials Science and Engineering, 2019
As an important index of soil fertility and ecological balance, soil organic carbon had been universal concern. This paper summarized research conditions of temperature and moisture on soil organic carbon in recent years, introduces the effects of ...

Nutrient supply from organic amendments applied to unvegetated soil, lettuce and orchardgrass [PDF]

open access: yes, 2006
Organic sources of nutrients are increasingly being used in horticultural and certified organic production. The nutrient-supplying potentials of poultry manure compost (PM), feather meal (FM), alfalfa meal (AA) and vermicastings (VC) and an unamended ...

Soil Properties and their Influence on Grassland Production under Low Input and Organic Farming Conditions [PDF]

open access: yes, 2006
End of project reportThis project set out to identify soil properties that most influence grassland production under low mineral nitrogen input conditions. Sixteen farms were selected in Counties Limerick and Clare and the soil sampled. Soil physical and

Short-Term Belowground Responses to Thinning and Burning Treatments in Southwestern Ponderosa Pine Forests of the USA [PDF]

open access: yes, 2016
Microbial-mediated decomposition and nutrient mineralization are major drivers of forest productivity. As landscape-scale fuel reduction treatments are being implemented throughout the fire-prone western United States of America, it is important to ...
