Soil water recharge for grassed and forested land covers on the Oak Ridges Moraine, southern Ontario, Canada
Soil water recharge (R) below 1 m depth was estimated via a 1-d water balance for grasslands, hardwood stands and red pine plantations on the Oak Ridges Moraine (ORM) in southern Ontario, Canada. Annual R values (431–696 mm) were in the order of previous estimates for outcropping sands and gravels on the ORM (∼400 mm); however, they only partially supported hypothesized differences in R ...

Effect of N-(n-butyl) Thiophosphoric Triamide and 3,4 Dimethylpyrazole Phosphate on gaseous emissions from grasslands under different soil water contents
The intensification of grassland systems is leading to serious environmental risks due to the large input of nitrogen (N) in fertilizers and the subsequent gaseous losses. Addition of nitrification inhibitors (NI) or urease activity inhibitors to fertilizers could reduce these losses to the atmosphere. In the present study, the effects of the nitrification inhibitor 3,4-dimethylpyrazole phosphate ...

Historic record of pasture soil water and the influence of the North Atlantic Oscillation in south-west England
The North Wyke Farm Platform for sustainable grassland research in south-west England contains infrastructure measuring soil moisture and field runoff. Its time series of sensor data is used to validate the parsimonious SH2O-NW model for soil water at field-scale. Thirty-four years of daily soil moisture and runoff is simulated, and used to detect long-term trends and produce a risk analysis. ...

Losing Soil
In 1938, Walter Lowdermilk, a senior official in the Soil Conservation Service of the U.S. Department of Agriculture, traveled abroad to look at lands that had been cultivated for thousands of years, seeking to learn how these older civilizations had coped with soil erosion. He found that some had managed their land well, maintaining its fertility over long stretches of history, and were ...

Impact of Agri-environment measures
The application of agri-environment contracts concerning 1 farmer in every 7 and delivering environmental services over 20% of European farmland, marks a very significant step towards sustainability. The target set in the 5th Environmental Action Programme of 15% coverage by 2000 has thus already been exceeded. The requirement on Member States to apply the regulation throughout their territories ...
