Influence of organic and mineral amendments on microbial soil properties and processes
Microbial diversity in soils is considered important for maintaining sustainability of agricultural production systems. However, the links between microbial diversity and ecosystem processes are not well understood. This ...
Effects of past and current crop management on soil microbial biomass and activity
(Springer Berlin / Heidelberg, 2007-06)
Because soil biota is influenced by a number of factors, including land use and management techniques, changing management practices could have significant effects on the soil microbial properties and processes. An experiment ...
Using nitrogen : what is best practice?
(South Island Dairy Event (SIDE), 2005-06)
Feed shortages occur in spring because the rate of pasture growth is below the cow demand. Spring pasture growth rate is slow in the South Island because the soil temperature is low and the rate of nitrogen (N) supply from ...
Phosphorus exchangeability and leaching losses from two grassland soils
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2002)
Although phosphate phosphorus (P) is strongly sorbed in many soils, it may be quickly transported through the soil by preferential flow. Under flood irrigation, preferential flow is especially pronounced and associated ...
Small-scale spatial variability of selected soil biological properties
A strategy for sampling soil from intact monolith lysimeters was established based on measurements of spatial heterogeneity within the lysimeter area. This was part of an ongoing study to determine relationships between ...
